Do I need a new Roof? — Repair or Replace?

If your roof isn’t very old and you spot a few loose or damaged shingles, you may be able to just replace them. But for broader or more extensive damage, it may be time for a new roof. The key is a regular roof inspection so you know what’s going on up there. We have put together the top Key Danger Signs your roof could be in need of replacement.

What goes in to a new roof?

It’s a lot more than just shingles. Cobra Attic Ventillation helps reduce attic moisture and heat. Leak Barriers help prevent leaks caused by wind-driven rain and ice dams. Roof Deck Protection helps shield the roof deck from moisture infiltration. Starter Strip Shingles help guard against shingle blow-offs. Ridge Cap Shingles are the finishing touch that helps defend against leaks at the hips and ridges. And when you install any GAF Lifetime Shingle & at least 3 qualifying GAF Accessories & you’ll automatically get: a Lifetime ltd. warranty on your shingles and all qualifying GAF accessories!* PLUS Non-prorated coverage for the first 10 years!

Does it come with a warranty?

All shingles are backed by GAF’s industry leading Shingle and Accessory Limited Warranty which is automatically included with your installation so no need to register. And we don’t stop there, Roofing system, System Plus Warranties cover materials and workmanship beyond the Shingle and Accessory. StainGuard Plus is available on select shingles to protect against blue-green algae, and the Wind Proven Limited Wind Warranty with no maximum wind speed limitation. So you can sleep easy at night knowing your roof is protected for many years to come.
