How to compare roofing estimates.

Check that the proposals describe the same job

A roofing estimate is a description of a project as well as a price. Before deciding which offer looks better, check whether both contractors are proposing repair or replacement, which roof areas are included, and how they reached that recommendation.

If one proposal recommends a repair and another recommends replacement, use our roof repair versus replacement questions to clarify what each option resolves before comparing prices. If the proposed approaches differ, ask each contractor to explain why. A useful answer connects the work to observations about your roof. Ask for photos or written findings you can review from the ground; this guide is not an invitation to climb onto a roof.

Read the scope in layers

Create a comparison sheet with a column for each proposal. Record the proposed material and product line, removal and disposal, treatment of existing layers, flashing details, and any ventilation work. Add a row for the treatment of damaged decking discovered after work begins. Mark anything not stated as “needs clarification,” rather than assuming it is included.

Put two roofing proposals side by side

Download the roofing quote comparison worksheet (.txt). Save it on your device or print it from a text editor. It gives each proposal a place for the roof areas, materials, removal, flashing, ventilation, decking repairs, exclusions, schedule, and service terms. Keep the original proposals alongside your notes.

Fill in only what the contractor has confirmed. Use “needs clarification” for an unanswered item and “not included” for an explicit exclusion. Those mean different things: an unanswered question is not a zero-cost item.

When the lower total leaves work out

Illustrative example: Proposal A excludes disposal; Proposal B includes disposal but leaves possible decking repairs unpriced. Ask A for a written disposal price and ask both contractors how any decking repairs would be measured, priced, documented, and approved. A listed unit price is not a final amount when the quantity is unknown.

Record confirmed extras separately from optional upgrades. Do not add an item twice if a revised proposal already includes it. If the scope or product still differs, label the proposals as different options instead of treating their totals as interchangeable.

A follow-up message to send with your questions

Before I compare these proposals, please confirm the roof areas and products included, the removal and disposal work, and any exclusions. How would additional decking or other concealed work be documented, priced, and approved? Please send a revised written proposal for any changes, with the schedule and product and workmanship warranty documents.

The worksheet organizes your questions; it does not assess roof condition, certify a contractor, or replace the written proposal.

Look at the contractor behind the proposal

NRCA recommends evaluating a contractor’s business credentials, insurance, references, and written proposal; price is only one consideration. Check the details with the relevant issuer rather than relying only on a logo or badge in a sales presentation. NRCA: selecting a roofing contractor ↗

Ask who will supervise your job, who will answer questions during the work, and how you will receive updates. A clear point of contact matters when a detail needs to be resolved quickly.

Resolve gaps before signing

The FTC recommends written estimates describing the work, materials, completion date, and price. It also advises checking licensing and insurance and not paying the entire amount upfront. FTC: choosing a home improvement contractor ↗

Ask the contractor to revise the proposal when a conversation changes the scope. Save the version you accept along with the product information and warranty terms. Discuss permits, payment milestones, and how any change orders will be approved before work starts.

Ask Chatter can help you explore a roofing partner option. The provider must assess your project and supply its own quote; a chat result is not a roof inspection or a recommendation to replace.
