DecoRidge® 8 Inch
Complete shingle application on roof deck before applying hip and ridge shingles. Hip shingles must be applied before applying ridge shingles. All hip and ridge shingles are applied with an 8 inch exposure.
Note: If a new roof is being applied over an existing roof, remove the old hip and ridge shingles to obtain a level application.
Use nails only when installing this product. Nails must be corrosion resistant, 11 or 12 gauge, with heads at least 3/8 inch in diameter.
Standard Fastening Pattern: One nail should be placed 8 1/2 inches back from the exposed end and 1 inch in for each side edge. (Fig. 1)
