1. Scope of work: repair, replacement, or full GAF system
The first step in pricing a GAF project is defining what the roof actually needs. In some situations, a focused repair using GAF shingles to match existing roofing may be enough. In others, the roof is worn out and a full tear-off and replacement is recommended. You may also choose a complete GAF roofing system with compatible underlayment, starter strips, ridge caps, and ventilation components. A full system with tear-off is a larger investment than small repairs or partial work, but it is also what can open the door to enhanced and lifetime limited warranty options on qualifying projects. During an estimate visit, the contractor evaluates whether repair, overlay, or full system replacement makes the most sense for your roof and builds the cost around that scope.
