Roof replacement is a major household project, and the lowest bid is not automatically the best value. Before signing an agreement, make sure each estimate is describing roughly the same work.
1. What exactly is included in the scope?
Ask whether removal of old materials, decking repairs, flashing, vents, underlayment, cleanup and disposal are included. A detailed scope makes competing estimates easier to compare.
2. Which roofing system is being proposed?
Material brand, product line and installation method matter. Ask for the exact product, not just a generic label such as “architectural shingles.”
3. How will unexpected deck damage be handled?
Rot or damaged decking may not be visible until the old roof is removed. Ask how additional work is priced and approved before it is performed.
4. What warranty applies?
Separate the manufacturer warranty from the contractor’s workmanship warranty. Ask what each one covers, how long it lasts and what could void coverage.
5. Are permits and inspections included?
Confirm who is responsible for permits, inspections and any local requirements.
6. How will the property be protected?
Ask how landscaping, driveways, siding and gutters will be protected and how debris will be contained.
7. What is the payment schedule?
A written schedule should explain deposits, progress payments and the final payment. Avoid relying on verbal promises.
Before you decide
Keep copies of estimates, contracts, warranties and important communications. For regulated services or high-value projects, independently verify credentials or requirements that apply in your location.
