GENERAL

This category covers materials intended to provide Classes A, B and C coverings on combustible (wood, 3/4-in. thick sheathing boards or 3/4-in. thick plywood unless otherwise indicated) decks when applied in accordance with detailed instructions included with the packages.

The use of 15/32-in. thick (minimum) plywood is a suitable alternate to 1/2-in. thick (minimum) plywood specified in the certifications for individual manufacturers.

The use of 3/8-in.-thick (minimum) nonveneer PS-2-rated sheathing (oriented strandboard panels, structural particleboard panels, composite panels or waferboard panels) is a suitable alternate to 1/2-in. thick (minimum) plywood specified in the certifications for individual manufacturers when a certified underlayment is utilized between the sheathing and the prepared roof covering.

Certifications are applicable either for new work or for recovering purposes.

Flashings and trimmings are intended to be the same as or not less than the equivalent of the roof coverings in each class, or of 16 oz. or heavier copper, No. 26 USS gauge or heavier galvanized steel, or 0.019-in. thick or heavier aluminum.

This category also covers shingles with factory-applied adhesives or integral locking features. The certification markings for such shingles may, in addition to fire-resistance information, include wind-resistance information.

PREPARED ROOF COVERINGS

Asphalt Organic-Felt Shingle Coverings are composed of asphalt organic-felt (previously identified as rag-felt) grit-surfaced shingles, one or more thickness, laid in accordance with the instruction sheets accompanying the packages. These coverings are limited to roof decks capable of receiving and retaining nails and to inclines sufficient to permit drainage.

Asphalt Glass-Fiber Mat Shingle or Sheet Roofing Coverings are composed of asphalt glass-fiber mat, grit-surfaced shingles or sheet roofing, laid in accordance with the instruction sheets accompanying the packages. These coverings are limited to roof decks capable of receiving and retaining nails and to inclines sufficient to permit drainage.

Modified Asphalt Glass-Fiber Mat, Asphalt Organic-Felt or Glass-Fiber/Polyester Composite Shingle Coverings are composed of modified asphalt-coated glass-fiber mat or glass-fiber/polyester composite, grit-surfaced shingles, laid in accordance with the instruction sheets accompanying the packages. These coverings are limited to roof decks capable of receiving and retaining nails and to inclines sufficient to permit drainage.

Wind-resistant Asphalt Glass-Fiber Mat Shingles are provided with field-applied or factory-applied adhesive or integral locking tabs. Some shingles with factory-applied adhesive utilize bands or spots of a heat-sensitive adhesive located either on the surface of the shingles or on the back side of each tab. Adhesives of this type must be activated by solar heat of intensity generally attained on warm, sunny days. Other shingles with factory-applied adhesive utilize a combination pressure-sensitive and heat-sensitive adhesive. Due to the nature of adhesives of this type, sealing is induced by application of pressure and/or heat.

Hip and Ridge Shingles are composed of asphalt or modified asphalt-coated glass-fiber mat surfaced with granules and are intended to be installed as specified on packaging supplied with the product for hip and ridge installations only. They are investigated for fire resistance in accordance with the fire test portion of UL Subject 2375, "Outline of Investigation for Hip and Ridge Shingles." Where indicated, they have also been investigated for wind resistance in accordance with the test procedures of UL Subject 2375. The class of shingles and performance criteria are in accordance with ASTM D3161. Wind-resistant hip and ridge shingles may utilize locking mechanisms, field-applied adhesives or factory-applied heat-sensitive adhesive which must be activated by solar heat of intensity generally attained on warm, sunny days.
