The Gregor Roofing Advantage
GAF Lifetime Roofing Systems
At Gregor Roofing, we look at your roof as an integrated system. Each part of the system affects the other. The correct installation of the roof, gutters and ventilation all work together for the optimal long term function of your roof, protecting your investment.
When you install any GAF Lifetime Shingle and at Least three qualifying GAF accessories, you’ll automatically receive a Lifetime ltd. warranty on your shingles and all qualifying GAF accessories!*
The GAF Lifetime Roofing System has earned the prestigious Good Housekeeping Seal, which means that Good Housekeeping stands behind the products in this system.
