Roof repair or replace: compare the exact area and work
A patch and a full reroof do not cover the same surface or future risk. Begin with the documented location and cause of the problem. Then inspect the replacement proposal's tear-off, decking allowance, flashing, underlayment, ventilation, cleanup, and warranty before interpreting any price gap.
What changes the answer?
- Ask for photos or an inspection record that locates the damage and explains why a localized repair is or is not viable.
- Separate a fixed installed total from allowances and change-order conditions. Hidden decking damage can make an apparently cheaper proposal incomplete.
- Compare the scope and materials in each written estimate. A lower total does not necessarily mean the same roof assembly or the same labor warranty.
Check the written proposal
Look for these items in each quote. If one is missing, ask whether it is excluded or will be priced later.
- Tear-off area, disposal, and any decking allowance
- Flashing, underlayment, ventilation, and permit
- Material specification, cleanup, exclusions, and workmanship warranty
Questions to take back to the contractor
- Where exactly is the failure, and what evidence supports a full replacement?
- How much decking repair is included before a change order?
- Which flashing and ventilation work is part of the stated price?
Compare your real numbers
Enter the repair quote now, even if you do not yet have a replacement price. Add up to three complete proposals later and keep their rebates and scope separate.

This is a scope and cash worksheet, not a roof inspection. It does not estimate life remaining or turn regional weather into a roof-failure probability. Active leaks near wiring or structural hazards require qualified attention.
