When a roof is past patching, a replacement is the honest answer. We strip the old shingles down to the deck, replace any rotten sheathing, and rebuild the whole system: underlayment, ice and water at the valleys and eaves, drip edge, new flashing, ridge vent, and shingles. One crew, start to cleanup.
The crew that inspects your roof is the crew that replaces it. One point of contact from the first ladder to the final magnet sweep.
A specific number for your roof, in writing, that does not move after the inspection unless you approve added deck repair.
Installed to shed water and stood behind. 5 stars on Google says the roofs hold up.
Tell us the address, the age of the roof, and what you are seeing inside. We will inspect it and put a fixed number in writing, for free.
