Review my roofing bid
A roofer handed you a number and a signature line. Roofing proposals are among the shortest documents in construction and among the easiest to under-scope — tear-off, decking, flashing, ventilation, and disposal are routinely left undefined.

Questions homeowners ask
How do I know if my roofing quote is too high?
Price alone rarely answers that. Two roofing bids can differ by 40% and both be fair if one includes tear-off, new flashing, decking allowance, and a manufacturer warranty and the other does not. We show you a typical cost range for your state and, more importantly, what each estimate does and does not include.
Can you tell if my roof was installed correctly from photos?
No, and no honest reviewer would claim otherwise. We flag things in your photos that are worth verifying — visible flashing details, fastener patterns, transitions — and give you the exact question to put to your contractor or an inspector.
