Warranty details describe the standard warranty included with installation. There are additional coverage options available for most products. You can elect for more coverage when ordering your product.

Asphalt roofing shingles generally all carry the same wind resistance classifications: ASTM D3161 Class F and ASTM D7158 Class H. However, wind rating is the specific warranted wind coverage by individual products.

Class A is the highest rating, offering the highest resistance to fire, followed by Class B, Class C, and unrated is the worst. A standard fire test with the following performance criteria is used to determine the fire rating of a roof covering: 1) flame penetration through the roof covering into the attic space, 2) flame spread over the surface of the roof covering, and 3) the propensity for the roof covering to become dislodged and generate embers.

Impact resistant shingles are designed to withstand hail and their durability rating is established by administering the UL 2218 impact test. Shingles are granted a rating of Class 1, 2, 3, or 4 based on the degree of impact they can withstand without cracking. The criteria for a Class 4 rating is whether a 2-inch steel ball dropped from a height of 20 feet directly onto the shingle being tested cracks through the shingle. If not, the shingle receives Class 4 impact rating. To achieve Class 3 rating, the shingle must withstand a 1 ¾-inch steel ball dropped from 20 feet. Roofle considers Class 3 and 4 to be impact resistant.

Algae growth on roofs can leave unsightly black streaks, cover UV resistant granules, and possibly leading to damaging moss growth. Coastal, warm and humid climates tend to create the friendliest environments for algae growth. To prevent this, some products incorporate copper-containing granules on the surface of the shingle.

The nominal dimension is the approximate size of each individual shingle or piece of material as sold by the manufacturer.

Exposure is the amount of material after installation that remains exposed to weather. The standard asphalt roof shingle exposure is 5" or 5 5/8" (metric shingles). For 12-inch wide shingle materials this means that the headlap or covered portion of each shingle course will be 7.
