Owner Brad Caldwell, of Caldwell’s Roofing, successfully passed the GAF Steep Slope Pro Field Guide with a 97/100 score. Passing this manufacturer’s exam means that we have been instructed in how the manufacturer requires their shingles to be installed.
One reason this is important is because if the shingles are not installed as per manufacturer’s instructions, the manufacturer’s limited lifetime warranty is automatically voided. If you want your manufacturer’s warranty to mean something, the roofers must install your roof per the specs.
GAF has a number of Pro Field Guides, but this one that deals with “steep-slope roofs” (i.e., anything 2:12 slope or higher) is the most necessary for residential applications. This guide covers safety principles, roof tear-off, decking assessment, roof preparation (underlayments and leak-barriers), attic ventilation requirements, shingle fasteners, proper installation of various GAF style shingles (3-tab, dimensional, designer), proper flashing details, roof transition areas, and low-slope sections of a roof.
Other GAF Pro Field Guides include one for low-slope roofs (≤2:12 slope) (the “Single-Ply Pro Field Guide”), one entitled “Low Slope Repair/Maintenance/Restoration Pro Field Guide,” one entitled “Asphalt Pro Field Guide,” and yet another one called “TruSlate Pro Field Guide” (for installing GAF’s TruSlate product).
GAF has provided a wealth of proper-installation information, and Caldwell’s Roofing wants to do their best to put that info to use on your roof!
