SnapNrack Roof Attachment

About

SnapNrack Roof Attachment Components SnapNrack offers a variety of roof attachment components. Some may be used individually, while others require a combination of components. The flashed L-foot is recommended for simple flush mounts to a roof with composition shingles. Roofs with tile or thick roofing material will probably require standoffs . The Corrugated Roof Block allows attachment of the L-foot directly to structural members covered with corrugated metal without collapsing or crushing the ridge in the roof material. The Hanger Bolt Clamp allows a versatile installation on roof surfaces which won't allow L-feet or standoffs. Configuring tilt angles from 0 to 10 degrees simply requires SnapNrack standoffs. A 5-1/2 standoff on the lower rail and a 7 standoff for the upper rail allows adjustability for shallow tilts. For angles from 10 to 45 degrees, use standoffs for both upper and lower rails, then extend the upper edge with sections of rail cut to length and drilled with two holes. Tilt leg rails can be cut and drilled in advance to save time on the job site. A simple drill guide will help with locating the holes in the tilt leg. If the length of the cut-rail leg exceeds 4 feet, consult a structural engineer before proceeding.
