Hail Exposure and Damage
Often times, it takes a trained technician to process, evaluate and detect Wind and Hail damage on a roofing system. It seems that everyone will have a different assessment on the extent of the damage. The damage may be highly visible dents and tears to the shingle, or it can be almost undetectable indentations along with very small granule loss. In either case, even small amounts of damage can compromise the integrity of the material and cause premature deterioration. If the shingle has exterior damage it may compromise the underlying components to a certain degree. When Hail impacts a shingle, the strike force from the Hail stone may damage the granule surface in the top asphalt coating, which may loosen the granules causing premature separation. The granule surfacing is necessary to protect the shingle from ultraviolet radiation, caused by the sun. Once the granule surface is damaged the shingle will eventually deteriorate and expose the fiberglass substrate, which may cause a leak in the roofing system. When a roofing system suffers severe Hail damage, the fiberglass substrate may be physically broken compromising the integrity of the shingle. There is really no way to determine the extent of the damage on the shingle without visible damage. It may take months, or even years for a roofing system to expose outside damage caused by Hail. Under the terms of our Limited Warranty, there is no coverage for damage caused by hail or wind. If the shingle is damaged by hail or wind, the manufacturer will still continue to warranty the material against manufacturer’s defects. Look for the following conditions when evaluating Hail and Wind damage:
Tears in the Shingle
– Tears are rips and creases in the shingle. They are usually found on 3-tab systems, hips, ridges, sides and edges of the shingle.
Indentations in the Shingle
– Indentations can be large impact round or half-moon shaped. Small indentations may expose granule loss and require the technician to lightly rub their hand over the shingle to feel the indentations. It may require the technician to lift the shingle so they can feel the backside for any irregularities.
Excessive Granule Loss
– May expose the fiberglass membrane and be an indicator of possible damage. Accelerated granule loss will significantly reduce the life of the shingle.
Other Collateral Damage:
- Broken skylights
- Broken glass
- Broken glazing beads on the windows
- Dents on the soft metals
- Tree or shrub damage
- Car dents
All Hailstones are different and vary in size, shape and hardness. They will create a distinct pattern of dents and depressions consisting of various sizes, shapes and depths. If you have any further questions regarding hail and wind damage, contact your homeowner’s insurance carrier and/or the experts at Texas Home Contractor.

What to know during the construction of your new roof:
Scheduling your Project:
After we have engaged into a contract, we will contact you to arrange a convenient date and time to install your new roof. If you would like to request a specific date, please call our office at 888-804-7775.
We will call to inform you of both delivery and start dates. In the event we are unable to reach you we will leave a message on your answering machine or with the person who answers the phone.
Occasionally your project may be delayed due to bad weather conditions. If we feel bad weather may be imminent, we will notify you of schedule changes. Our installation crews are fully prepared in case the weather should turn bad unexpectedly during the installation of your project. The crews will seal your roof, with visqueen, to prevent water from entering your home and we will resume work as soon as the weather permits.
The material for your project will be delivered on a large truck by a local shingle supply warehouse. The driver will use a forklift to unload the pallets off the truck. The sales representative will ask you where you want your roofing materials placed on your property. Please notify us 24 hours prior to delivery of any changes in your delivery.
Please call your sales representative, or the office at 888-804-7775, if you have any questions or concerns during your roofing project. Even though our office hours are Monday-Friday 8:00 a.m. to 5:00 p.m. we will answer your call 24 hours a day, 7 days a week.
If you allow us to place a company sign in your yard, which helps us with our advertising, we will give you a credit towards your roofing project.
Shingles & Other Materials:
There will be shingles, starter strip, roofing felt, valley flashing, roofing nails, roof jacks and flashing metal delivered to your home. We will place these materials in a convenient spot, of your choosing, on your property.
Wiring, Plumbing and Air Conditioning:
Any electrical, plumbing, telephone, security, air conditioning or other service lines, according to F.H.A. standards should not be installed within 3 inches of the roof deck. The sales representative will inspect the roof and notify you if any such lines currently exist. We cannot and will not be held responsible for the puncture of improperly installed lines within 3 inches of the roof deck.
Light Fixtures, Mirrors & Pictures:
It is the homeowners’ responsibility to insure that these items are securely attached to your walls and ceilings. If you feel that they may become unattached during the installation process, PLEASE take them down. Sometimes small cracks or crows feet will appear in older plaster or in cases were the attic space between the sheetrock and plywood is very minimal. These problems are often caused by the vibrations of the hammer and are often unavoidable. We cannot assume responsibility for these damages, since there is no way of controlling or stopping these problems from occurring.
During Tear-Off, existing roofing materials have a tendency to fall between the decking materials on your roof, (especially on skip sheeting) into your attic. It is the homeowners’ responsibility to cover any items in the attic which you think would require protection. Even though there will be a thorough clean-up of the exterior of your home, we can only pick up approximately 98% of the nails that fall around the area. Mowing the yard prior to the roof installation will help maximize the amount of nails that the magnet will pick up.
The homeowner will allow all Texas Home Contractor employees and Sub-Contractors access to their driveways and yard. In addition, the homeowner will permit Texas Home Contractor to use the homeowners’ electricity. If there are no exterior duplex receptacles available, we will run an extension cord through a window or under a door. In very rare cases, if the driveway was not built properly you might develop a crack or two when the materials are unloaded. If this happens, we cannot assume responsibility for the damages. This is a very rare occurrence but has been known to happen.
Trees and Shrubs
: It is the homeowners’ responsibility to cut down or remove any obstructions that may detour us from completing the project. You may prefer to have the tree or trees trimmed professionally before we begin construction.
If the chimney flashing cannot be waterproofed once work begins, an additional charge may be added to the contract price to replace the flashing or counter flashing unless otherwise stated in your contract. Sometimes on older homes the brick on the chimney or the cap on top of the chimney will settle and sometimes cause cracking which may cause leaking later on down the road if it is not already leaking. We can only assume liability for the flashing around the chimney that we change out. If we see a problem we will let you know immediately and inform you of your options and how we might be able to help you. As a standard, we change out both step flashing and counter flashing at the base of the chimney when we replace the roof whether it needs it or not.
Arrangements to remove solar panels from the roof are the sole responsibility of the homeowner unless otherwise stated in your contract.
We remove and re-install antennas up to 20 feet in height, but we cannot be held liable for the old lead-in wire breaking. Satellite dishes will be reinstalled, but we cannot be held liable for reception. Sometimes you may need to have a repairman come out to realign your dish since our crews are not knowledgeable in this field.
Upon completion of your job, please check all interior connections of your furnace and hot water heater vent pipes. These pipes have a tendency to be dislodged when re-flashing the bases. Since these pipes exhaust carbon monoxide we strongly recommend having an HVAC certified contractor reconnect the pipes in the attic, we can help you take care of this.
Left over Material:
Any leftover materials remain the property of Texas Home Contractor. We customarily over ship a small quantity to insure adequate supplies for our crews.
Upon completion of the job, the roofing foreman, along with the salesperson or superintendent, will inspect the work and complete an inspection report. We ask that you meet with the foreman and salesperson to insure that you are 100% satisfied with the job.
: The payment for your roof will be due upon completion of your job. If this is an insurance claims job, we will require the first check (ACV) from the insurance company at the signing of the contract. The remaining balance that includes your deductible will be due at the time of completion. If recoverable depreciation is withheld by the insurance company until the job is complete, we will require payment of the deductible upon completion of job. We will file with the insurance company to release the depreciation check. Once you have received the depreciation check, you will need to contact us so that we may make arrangements to collect the check. Once the job is paid in full you will receive the receipt and warranty papers for the job.
Warranty: Your new roof will be covered by two warranties:
- Workmanship: Our Warranty covers any and all defects in craftsmanship. The specifics of the warranty are outlined in the contract that you signed.
- Material: This warranty is issued by the manufacturer and covers the material that was used. This warranty will be mailed to you 7-10 business days after we have received the final payment upon completion.

Most dimensional shingles are metric in size. The values have been changed to inches for clarity. If they aren't metric, then their measurements are like those of standard 3-tab strip shingles which is 36" by 12" with a 5" exposure or so. Most dimensional shingles are two pieces of material laminated together. Nailing on the nail line is a must because it is very important that the nails penetrate both pieces of material. With most dimensional shingles there is only about a 3/4" wide strip where both materials are laminated together. This is considered the nailing line.
These are tiles that were not originally nailed in place and they have since out of place.

EG (Nails): ELECTROGALVANIZED
- This method uses electricity and zinc anodes to put on a beautiful, shiny coating. The problem is that the coating is very then. The thin coating soon oxidizes away and allows rust to start. Many trade associations warn against using these nails in exterior applications. We recommend that when galvanized nails are specified for a project, ONLY HOT-DIPPED NAILS SHOULD BE USED
. It doesn't pay to skimp on the nails - since cheap nails that rust can be a real heartache down the line for the retailer, builder and home owner. If you want galvanized nails you need hot dipped nails (see hot dipped nails)

Hot Dipped Nails:
are immersed in molten zinc - insuring that each nail gets a thick, uniform zinc coating. Hot-dip galvanizing prevents corrosion by coating steel with zinc. The galvanized coating is metallurgically bonded to the underlying steel, forming an impervious barrier between the steel substrate and the corrosive environment. The hot-dip galvanized coating also preferentially corrodes to protect the fastener’s underlying steel and is able to protect small areas of the fastener’s steel that may become exposed when mechanically damaged. Hot-dip galvanizing is the most effective method for delivering both long-term barrier protection and cathodic protection.
Condition formed at the lower roof edge by the thawing and re-freezing of melted snow on the overhang. Can force water up and under shingles, causing leaks.

- (Replacement Cost Value) This is determined by your local prices for construction. Most policies have an endorsement for this, meaning your insurance company will pay for the full replacement cost. Check your policy, it will be on the endorsements page.
- This is determined by the RCV minus the ACV. Your adjuster will figure how much it costs to repair or replace your property. For example a roof that costs $5,000.00, usually has a life of 25 years. The roof has been on the house for 10 years. The adjuster will depreciate the roof 40%. So he will pay you an ACV of $3,000.00, holding back $2,000.00 until you get the roof done. If you do not use all of the $2,000.00, the insurance company will keep the difference. If you don’t have the roof replaced, you can keep the $3,000.00, but remember your roof is no longer insured.

There is no standard definition for a Roof Certification. You could probably talk to ten different Roofing Contractors about the meaning of a Roof Certification and you will get ten different answers. A Roof Certification is, loosely, a written opinion issued by a Licensed Roofing Contractor to certify that a roof is free of defects and should perform as designed for a certain period of time. The Roof Certification period is usually for 1 or 2 years and can be up to as many as 5 years. But, be very careful, a Roof Certification is not always a Roof Warranty against future roof leaks. Unless you have done business with a certain Roofing Contractor, you will need to know what their Roof Certification is all about, and what is included in, or excluded from, their Roof Certification.
A Roof Inspection is an inspection performed by a professional Roofing Company to determine the current condition of the roof. After a Roof Inspection is performed, a detailed Roof Report is provided which describes any current roofing conditions that need to be corrected and any preventative maintenance to prevent a future roof problem from occurring. The Roof Report will provide options, from roof cleaning, roof maintenance, simple roof repairs, major roof repairs, roof restoration, or it may even recommend that a complete roof replacement is necessary. A Roofing Contractor is able to charge a fee for a Roof Inspection because they are providing a Roof Report which goes beyond providing a simple Roof Repair Estimate. A Roofing Contractor will typically charge their customers up to $100 or more for the completion of a Roof Inspection and the issuance of the Roof Report.
A Roof Inspection and Roof Report are usually obtained when: purchasing a home as part of the buyer inspection process; when a seller is listing a property to be made aware of a roof problem that could affect their transaction; when a roof certification is required by a lender as a condition of loan funding; when a roof certification is required by a home owner insurance policy; or when a roof certification is required by a buyer, before closing on a property that they are purchasing, to make sure that the roof isn't going to be a problem after they move into the home. The Roof Report will contain an estimate to repair current damage to the roof, preventative maintenance to prevent future damage to the roof, and an offer for a Roof Certification Leak Warranty that will warranty that the entire roof is free from leakage for the next 2 or 3 years.

Hand sealing with plastic cement should be done to ensure sealing in winter.

Factory-applied adhesive that bonds shingle courses together when exposed to the heat of the sun after application.
That portion of roll roofing overlapped by the succeeding course to obtain double coverage.
Slight differences in shingle color that may occur as a result of normal manufacturing operations.
Exterior grade boards used as a roof deck material.
A roof containing only one sloping plane. Has no hips, ridges, valleys or gables.
refers to the end lap in any sort of roll roofing or felt. For instance the side laps for roofing felt should be over lapped a minimum of 12” for composition roofing and 2 feet for tile roofing. In regards to roof repair the side laps in not properly done will leak down the road. That is why many contractors feel that a tile roof repair is simply a patch or band aid type of repair. What many roofing contractors don’t know that is the side lap is properly done the repair can outlast the rest of the roof and would not be considered a patch or band aid but a permanent solution to a roof leak without completely replacing the whole roof.
Asphalt roofing that provides one layer of roofing material over the deck.
roofing tiles that are specifically made from real slate rock. You should not mistake concrete or clay tile for slate tile. Slate tile is known for its heavy weight, durability, and high cost.

This is a accessory piece of metal used where a tile roof terminates into a vertical side wall. The metal catches the water run-off from the vertical and keeps it from getting under the tile roof and eventually directs the water back on top of the tile roof even though it is installed under the tile. It comes in different widths and a 6” width is better than a 4” wide piece of tile pan.
That portion of the roofing covered by the succeeding course after installation.

Roof System Components
All steep-slope roof systems (i.e., roofs with slopes of 25 percent or more) have five basic components:
Choosing a Roof System
- Roof covering: shingles, tile, slate or metal and underlayment that protect the sheathing from weather.
- Sheathing: boards or sheet material that are fastened to roof rafters to cover a house or building.
- Roof structure: rafters and trusses constructed to support the sheathing.
- Flashing: sheet metal or other material installed into a roof system's various joints and valleys to prevent water seepage.
- Drainage: a roof system's design features, such as shape, slope and layout that affect its ability to shed water.
There are a number of things to consider when selecting a new roof system. Of course, cost and durability head the list, but aesthetics and architectural style are important, too. The right roof system for your home or building is one that balances these five considerations. The following roofing products commonly are used for steep-slope structures.
possess an overwhelming share of the U.S. steep-slope roofing market and can be reinforced with organic or fiberglass materials. Although asphalt shingles reinforced with organic felts have been around much longer, fiberglass-reinforced products now dominate the market.
- Organic shingles consist of a cellulose-fiber (i.e., wood) base that is saturated with asphalt and coated with colored mineral granules.
- Fiberglass shingles consist of a fiberglass mat, top-and-bottom layers of asphalt, and mineral granules.
Asphalt shingles' fire resistances, like most other roofing materials, are categorized by Class A, B or C. Class A signifies the most fire-resistant; Classes B and C denote less fire resistance. Generally, most fiberglass shingles have Class A fire ratings, and most organic shingles have Class C ratings.
A shingle's reinforcement has little effect on its appearance. Organic and fiberglass products are available in laminated (architectural) grades that offer a textured appearance. Zinc or copper-coated ceramic granules also can be applied to organic or fiberglass products to protect against algae attack, a common problem in warm, humid parts of the United States. Both types of shingles also are available in a variety of colors.
Regardless of their reinforcing type and appearance, asphalt shingles' physical characteristics vary significantly. When installing asphalt shingles, NRCA recommends use of shingles that comply with American Society for Testing and Materials (ASTM) standards-ASTM D 225 for organic shingles and ASTM D 3462 for fiberglass shingles. These standards govern the composition and physical properties of asphalt shingles; not all asphalt shingles on the market comply with these standards. If a shingle product complies with one of these standards, it is typically noted in the manufacturer's product literature and on the package wrapper.
Wood shingles and shakes
are made from cedar, redwood, southern pine and other woods; their natural look is popular in California, the Northwest and parts of the Midwest. Wood shingles are machine sawn; shakes are handmade and rougher looking. A point to consider: Some local building codes limit the use of wood shingles and shakes because of concerns about fire resistance. Many wood shingles and shakes only have Class C fire ratings or no ratings at all. However, Class A fire ratings are available for certain wood shingle products that incorporate a factory-applied, fire-resistant treatment.
—clay or concrete—is a durable roofing material. Mission and Spanish-style round-topped tiles are used widely in the Southwest and Florida, and flat styles also are available to create French and English looks. Tile is available in a variety of colors and finishes. Tile is heavy. If you are replacing another type of roof system with tile, you will need to verify that the structure can support the load.
is quarried in the United States in Vermont, New York, Pennsylvania and Virginia. It is available in different colors and grades, depending on its origin. Considered virtually indestructible, it is, however, more expensive than other roofing materials. In addition, its application requires special skill and experience. Many old homes, especially in the Northeast, still are protected by this long-lasting roofing material.
primarily thought of as a low-slope roofing material and has been found to be a roofing alternative for home and building owners with steep-slope roofs. There are two types of metal roofing products: panels and shingles. Numerous metal panel shapes and configurations exist. Metal shingles typically are intended to simulate traditional roof coverings, such as wood shakes, shingles and tile. Apart from metal roofing's longevity, metal shingles are relatively lightweight, have a greater resistance to adverse weather and can be aesthetically pleasing. Some have Class A fire ratings.
Synthetic roofing products
simulate various traditional roof coverings, such as slate and wood shingles and shakes. However, they do not necessarily have the same properties.
Before making a buying decision, NRCA recommends that you look at full-size samples of a proposed product, as well as manufacturers' brochures. It also is a good idea to visit a building that is roofed with a particular product.
Ventilation and insulation are key
One of the most critical factors in roof system durability is proper ventilation. Without it, heat and moisture build up in an attic area and combine to cause rafters and sheathing to rot, shingles to buckle, and insulation to lose its effectiveness.
Therefore, it is important never to block off sources of roof ventilation, such as louvers, ridge vents or soffit vents, even in winter. Proper attic ventilation will help prevent structural damage caused by moisture, increase roofing material life, reduce energy consumption and enhance the comfort level of the rooms below the attic.
In addition to the free flow of air, insulation plays a key role in proper attic ventilation. An ideal attic has:
- A gap-free layer of insulation on the attic floor to protect the house below from heat gain or loss.
- A vapor retarder under the insulation and next to the ceiling to stop moisture from rising into the attic.
- Enough open, vented spaces to allow air to pass in and out freely.
- A minimum of 1 inch between the insulation and roof sheathing.
The requirements for proper attic ventilation may vary greatly, depending on the part of the United States in which a home or building is located, as well as the structure's conditions, such as exposure to the sun, shade and atmospheric humidity. Nevertheless, the general ventilation formula is based on the length and width of the attic. NRCA recommends a minimum of 1 square foot of free vent area for each 150 square feet of attic floor—with vents placed proportionately at the eaves (e.g., soffits) and at or near the ridge.
Even roofs have enemies
A roof system's performance is affected by numerous factors. Knowing about the following will help you make informed roof system buying decisions:
Choosing a Contractor
- Sun: Heat and ultraviolet rays cause roofing materials to deteriorate over time. Deterioration can occur faster on the sides facing west or south.
- Rain: When water gets underneath shingles, shakes or other roofing materials, it can work its way to the roof deck and cause the roof structure to rot. Extra moisture encourages mildew and rot elsewhere in a house, including walls, ceilings, insulation and electrical systems.
- Wind: High winds can lift shingles' edges (or other roofing materials) and force water and debris underneath them. Extremely high winds can cause extensive damage.
- Snow and ice: Melting snow often refreezes at a roof's overhang where the surface is cooler, forming an ice dam. This blocks proper drainage into the gutter. Water backs up under the shingles (or other roofing materials) and seeps into the interior. During the early melt stages, gutters and downspouts can be the first to fill with ice and be damaged beyond repair or even torn off a house or building.
- Condensation: Condensation can result from the buildup of relatively warm, moisture-laden air. Moisture in a poorly ventilated attic promotes decay of wood sheathing and rafters, possibly destroying a roof structure. Sufficient attic ventilation can be achieved by installing larger or additional vents and will help alleviate problems because the attic air temperature will be closer to the outside air temperature.
- Moss and algae: Moss can grow on moist wood shingles and shakes. Once it grows, moss holds even more moisture to a roof system's surface, causing rot. In addition, moss roots also can work their way into a wood deck and structure. Algae also grows in damp, shaded areas on wood or asphalt shingle roof systems. Besides creating a black-green stain, algae can retain moisture, causing rot and deterioration. Trees and bushes should be trimmed away from homes and buildings to eliminate damp, shaded areas, and gutters should be kept clean to ensure good drainage.
- Trees and leaves: Tree branches touching a roof will scratch and gouge roofing materials when the branches are blown by the wind. Falling branches from overhanging trees can damage, or even puncture, shingles and other roofing materials. Leaves on a roof system's surface retain moisture and cause rot, and leaves in the gutters block drainage.
- Missing or torn shingles: The key to a roof system's effectiveness is complete protection. When shingles are missing or torn off, a roof structure and home or building interior are vulnerable to water damage and rot. The problem is likely to spread-nearby shingles also are ripped easily or blown away. Missing or torn shingles should be replaced as soon as possible.
- Shingle deterioration: When shingles are old and worn out, they curl, split and lose their waterproofing effectiveness. Weakened shingles easily are blown off, torn or lifted by wind gusts. The end result is structural rot and interior damage. A deteriorated roof system only gets worse with time-it should be replaced as soon as possible.
- Flashing deterioration: Many apparent roof leaks really are flashing leaks. Without good, tight flashings around chimneys, vents, skylights and wall/roof junctions, water can enter a home or building and cause damage to walls, ceilings, insulation and electrical systems. Flashings should be checked as part of a biannual roof inspection and gutter cleaning.
Purchasing a new roof system is an important investment. Before you spend your money, spend time learning how to evaluate roofing contractors. You should insist on working with a professional roofing contractor. NRCA wants to assist you in getting the kind of results you expect—a quality roof system at a fair price. All roofing contractors are not alike, and NRCA recommends that you prequalify roofing contractors to get the job done right the first time. The following guidelines will help you select a professional:
Commonly Asked Questions
- Check for a permanent place of business, telephone number, tax identification number and, where applicable, a business license.
- Don't hesitate to ask a roofing contractor for proof of insurance. In fact, insist on seeing copies of his liability coverage and workers' compensation certificates. (U.S. workers' compensation laws vary by state. Consult your state's laws to determine workers' compensation insurance requirements.) Make sure the coverages are in effect through the duration of the job. Many building and home owners have been dragged into litigation involving uninsured roofing contractors. Also, if a contractor is not properly insured, you may be liable for accidents that occur on your property.
- Check to see if the roofing contractor is properly licensed or bonded. Some states have specific licensing requirements, and others do not. Your state's Department of Professional Regulation or Licensing Board will have this information.
- Make sure the contractor is financially stable. A professional roofing contractor can provide current financial information about his company.
- Look for a company with a proven track record that offers client references and a list of completed projects. Call these clients to find out whether they were satisfied.
- Insist on a detailed, written proposal and examine it for complete descriptions of the work and specifications, including approximate starting and completion dates and payment procedures.
- Have the contractor list the roofing manufacturers with which his firm is a licensed or approved applicator. Most roof systems require special application expertise to achieve lasting quality.
- Have the contractor explain his project supervision and quality-control procedures. Request the name of the person who will be in charge of your project, how many workers will be required and estimated completion time.
- Check to see if the contractor is a member of any regional or national industry associations, such as NRCA. Being a member of industry associations demonstrates a commitment to professionalism.
- Call your local Better Business Bureau or Department of Professional Regulation to check for possible complaints filed against the contractor.
- Carefully read and understand any roofing warranties offered, and watch for provisions that would void it.
- Choose a company committed to worker safety and education. Ask the contractor what type of safety training he provides for his workers and what industry education programs they have attended. The best roofing contractor is only as good as the workers who install the roof system.
- Keep a healthy skepticism about the lowest bid. If it sounds too good to be true, it probably is. Many fly-by-night contractors' below-cost bids seem attractive, but these contractors often are uninsured and perform substandard work. Remember, price is only one of the criteria for selecting a roofing contractor. Professionalism, experience and quality workmanship also should weigh heavily in your decision.
How can a home owner recognize when a roof system has problems?
All too often, roof system problems are discovered after leaking or other serious damage occurs. Periodic (twice-a-year) inspections often can uncover cracked, warped or missing shingles; loose seams and deteriorated flashings; excessive surface granules accumulating in the gutters or downspouts; and other visible signs of roof system problems. Indoors, look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas.
What are my options if I decide to reroof?
You have two basic options: You can choose a complete replacement of the roof system, involving a tear-off of your existing roof system, or re-cover the existing roof system, involving only the installation of a new roof system. If you've already had one re-cover installed on your original roof system, check with a professional roofing contractor. In many instances, building code requirements allow no more than one roof system re-cover before a complete replacement is necessary.
My roof leaks. Do I need to have it replaced completely?
Not necessarily. Leaks can result from flashings that have come loose or a section of the roof system being damaged. A complete roof system failure, however, generally is irreversible and a result of improper installation or choice of materials or the roof system installation is inappropriate for the home or building.
Can I do the work myself?
Most work should not be done yourself. Professional roofing contractors are trained to safely and efficiently repair or replace roof systems. You can damage your roof system by using improper roofing techniques and severely injure yourself by falling off or through the roof.
Maintenance performed by home and building owners should be confined to inspecting roof systems during the fall and spring to check for cracked or curling shingles and cleaning gutters filled with dead leaves and other debris. If you must inspect your roof system yourself, use a firmly braced or tied-off ladder equipped with rubber safety feet. Wear rubber-soled shoes and stay on the ladder (and off the roof system), if possible.
How long can I expect my roof system to last?
Most new roof systems are designed to provide useful service for about 20 years. Some roof system types, such as slate, clay tile and certain metal (e.g., copper) systems, can last longer.
Actual roof system life span is determined by a number of factors, including local climatic and environmental conditions, proper building and roof system design, material quality and suitability, proper application and adequate roof maintenance.
Roofing product manufacturers offer a variety of warranties on their products. Take a close look at those warranties to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.
What will a new roof system cost?
The price of a new roof system varies widely, depending on such things as the materials selected, contractor doing the work, home or building, location of the home or building, local labor rates and time of year. To get a good idea of price for your roof system, get three or four proposals from reputable contractors in your area. Keep in mind that price is only one factor, and it must be balanced with the quality of the materials and workmanship.
For each roofing material, there are different grades and corresponding prices. There also are a variety of styles and shapes. You need to look at the full product range and make a choice based on your budget and needs.
Within the roofing profession, there are different levels of expertise and craftsmanship. Insist on a contractor who is committed to quality work.
How can I determine my annual roofing cost?
When considering your roofing options, the following formula may help:
Total Cost (Materials and Labor) ÷ Life Expectancy of Roof System (in years) = Annual Roofing Cost
Terms you should know
