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?

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.
