Damaged roof decking cut out and new plywood sheets going down over the rafters during a tear-off — Damaged decking found during a tear-off. We photograph it, show you, and replace it with new plywood before the new roof goes on.

Ask every roofer for a written, itemized price. If two estimates are far apart, the line items tell you why.

How to compare estimates

Line up the estimates side by side and check that each one includes tear-off, decking allowance, ice & water shield, underlayment, flashing, ventilation, disposal and permit. A low price that leaves out three of these is not a low price.
