Reid’s Roofing is a GAF Certified Contractor. The GAF Weather Stopper® System Plus Ltd. Warranty provides coverage against manufacturing defects for all major GAF components on your roof (not just your shingles) — so you’ll have the peace of mind of knowing that, if any covered roofing component fails, it will be covered by the warranty. The warranty is available through GAF’s factory-certified contractors, and is a low-cost way to get up to 50 years of non-prorated coverage (against manufacturing defects) on your new roofing system. For the small additional cost of the System Plus ltd. warranty, this is probably the best value you can get for your investment. Contractor’s who do not hold the certified Program can only offer the basic 10 year pro-rated warranty.
