Roof Pitch

Allsteel roofing panels require a minimum 4/12 pitch to ensure proper water drainage, and to prevent water from siphoning over the ribs. A 4/12 pitch means that there is 4 inches of rise for every 12 inches running horizontally. Lap screws and sealant are recommended when the pitch is less than 4/12, and optional when the pitch is 4/12 or greater. As a general rule, the less steep the roof, and the more essential that sealant be used at all side-laps. Check with our representatives for suggestions for your particular roof pitch, and about roofing options if you have less than a 2/12 pitch.
