The WellRoof® Guarantee Extension requires an extensive annual inspection performed by Collis Roofing, a GAF Certified Maintenance Professional (CMP). This gives you the peace of mind that your roof is performing as it was intended—while meeting the requirements to maintain your guarantee coverage!
Exterior (Evaluate exterior of building for obvious evidence of existing or potential leaks.)
Interior (Examine interior roof deck, walls, and ceiling for evidence of leaks.)
Roof Perimeter (Evaluate base flashing, metal work, caulking, and anything that would affect the watertight integrity of the roof.)
Field of Roof (Examine the condition of the roof; look for evidence of leaks, debris, or damage to the membrane. Also check ancillary items; evaluate penetrations for proper detailing and evidence of potential leaks.)
