What Is Impact Resistant Roofing?

There are several roofing products on the market that resist hail, reducing your Insurance costs. Feel free to ask your sales representative for samples during your initial consultation.


To qualify in Texas as "impact resistant roofing" the roofing product must meet Underwriters Laboratory testing requirements under designation UL-2218. Roofing materials successfully tested by Underwriters Laboratory in accordance with UL-2218 are classified as to impact resistance in one of four classes, Class 1 - Class 4. A Class 4 roof covering offers the best hail protection and will receive the highest discounts on insurance premiums. Even more specifically, the shingles must meet other more specific requirements of the Texas Insurance Department. All manufacturers of roofing materials* eligible for the impact-resistant roofing discount adopted by the Texas Department of Insurance must label their products with the following information:

1) The proper Underwriter's Laboratories label or label from any other testing lab approved by the Texas Department of Insurance
 2) The impact-resistance classification
     (Class 1, Class 2, Class 3, Class 4) of the product under U.L. Standard 2218
3) The manufacturer's name
4) The year manufactured
5) The brand name of the roofing product

Do I Have Defective Roofing Materials?

All composition roofing will eventually wear out from the effects of the ultra-violet rays of the sun and the wear and tear of the elements. Our concern right now is when manufacturing defects cause composition shingles to prematurely fail. This does not happen often, but in our huge Texas marketplace and our many years of experience, we have seen manufacturer's defects create premature failure hundreds of times. The premature wearing out of composition shingles can be manifest in many ways. Here are 4 specific examples.

  • Granular failure
  • Delamination
  • Blistering
  • Cracking or Spawling

Not all pre-mature failure is caused by manufacturer's defects. We need to be very careful not to confuse shingle problems caused by manufacturer's defects from shingle failure problems created by a lack of proper ventilation or even hail damage. Inadequate attic ventilation can cause premature roofing failure. Roofs can suffer pre-mature failure due to mechanical damage created by foot scuffs or tree limb damage or other mechanical factors. Each of these roofing failure modes has nothing to do with manufacturer's defects.

Manufacturers Warranties and Installation requirements for Composition Shingles
Each manufacturer of composition roofing sells an initial warranty on their products and has a proper installation method for their materials. On those occasions when these manufactured products, usually organic and asphalt shingle products, prematurely fail, homeowners can create a claim for warranty coverage.

Are you concerned that your composition roof is prematurely failing? We would be happy to help you understand what you are dealing with. We can help you document your situation and assist you with a warranty claim. Showtime Exteriors has helped guide of homeowners over the years through this process. Let us help you with the "knowing the what, how and where" to process your manufacturer's defect claim.

Does My Roof Meet City Codes?

If you have Wood Shake or Wood Shingles Underneath your existing roof, the answer isNO!
Insurance companies have deemed this a Fire Hazard!

• The 2003 IRC (International Residential Code) states.......... R905.2.1 Sheathing Requirements: Roof Covering shall be fastened to solidly sheathed decks. Any roof which is roofed over Wood Shake or Wood Shingles and has any storm damage to any portion of the existing roof, the entire roof must be re-decked to conform to code.

• Showtime Exteriors offers free inspections to see if you qualify for this code compliance upgrade and full roof replacement. This is also the time to take advantage of some energy efficient roofing products that will reduce your electric bill and insurance premiums up to 30%. Also, by making your house energy efficient you will be entitled to a break on your next income tax return.

• Although some roofs are sold as lifetime - i.e..Alcoa aluminum, most of which are attached to wood shake or wood shingles and the smallest hail will damage this roof. Insurance companies are paying to remove the aluminum, the wood shake, and paying to re-deck the entire roof.

• Allow Showtime Exteriors to get your largest investment up to specifications on local city codes.

What Affects My Roofs Performance?

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 grow 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 flashingaround 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.
