How to choose a roofer and compare roofing estimates

A clear roofing estimate tells you what happens when the old roof comes off.

The answer in 2 lines. Get competing written estimates after an inspection, verify required licensing and request proof of insurance. Compare the same scope, including removal, materials, flashing, damaged decking, permits, cleanup and payment terms. Licensing, deposits, contract requirements and cancellation rights vary by state. Do not sign under pressure after a storm, pay the entire price upfront or rely on an oral promise that insurance will cover everything.

Start with these checks

Ask each roofer to inspect the proposed work and provide a detailed written estimate. Request photographs so you can discuss findings from the ground.
Ask which state or local license or registration applies, then verify it with the issuing authority rather than accepting an advertisement as proof.
Request evidence of liability insurance and applicable workers' compensation coverage. Make sure the business identity matches the estimate and contract.
Give each bidder the same project description, then ask them to explain differences in scope and price.

Stop: danger

Stay off the roof: do not climb up to inspect damage or accompany a salesperson. Ask for photographs and an explanation from a safe location.
Active structural danger: keep people away from falling roofing materials or a visibly sagging ceiling. Arrange a safety assessment before ordinary estimating continues.

Verify credentials for your location

The FTC contractor guidance explains license, insurance and estimate checks. Use its consumer-protection links to identify the appropriate office for your location and ask which roofing credentials and deposit rules apply.

For a concrete state example, use the California contractor selection page and follow its license-status link. Match the business and roofing classification, review status and check insurance information. California's requirements are specific to California; a registration elsewhere may provide different protections.

A bond, a business registration and liability insurance serve different purposes. Ask what each document actually covers and who handles a claim. Do not assume a credential guarantees workmanship or reimbursement.

What not to do

Signing because a salesperson says leftover materials make the offer available only today.
Comparing a repair estimate with a replacement estimate as though they cover identical work.
Leaving blank spaces in the contract or relying on a verbal warranty.
Paying the full contract price before the work is completed and reviewed.

Make the estimate specific

Ask the roofer to identify the roof areas included and whether existing roofing will be removed. Have the estimate describe underlayment, flashing, ventilation, edges and penetrations, along with the roofing material's specification. These are comparison questions, not a universal construction prescription: the right assembly depends on the roof and local requirements.

Ask how concealed damage will be handled. For example, if deteriorated decking becomes visible after removal, who documents it, how is the extra cost calculated and when must you approve it? Require written approval for changes before extra work proceeds.

Include responsibility for permits, inspections, protection of landscaping, temporary weather protection and debris removal. Ask who supervises the crew, whether subcontractors will be used and whom you contact if the property is left exposed.

Read payment, warranty and cancellation terms

The contract should connect payments to clearly described progress and identify expected start and completion arrangements. Ask what happens if weather delays work. Separate the workmanship warranty from any material warranty, and get the exclusions and claim procedure in writing.

Some home sales have federal cancellation protections, but coverage and exceptions matter. Read the FTC Cooling-Off Rule summary and follow its rule-text link before relying on a right to cancel. Ask the applicable state consumer office about additional protections. Do not assume every roofing contract has the same cancellation period.

If problems arise, document them and request a written response. California residents can use the state attorney general's contractor page to follow the licensing-board complaint route. Elsewhere, use the relevant local regulator.

Good to know

Ask references about leaks after completion, cleanup and how the roofer handled callbacks.
If you are filing an insurance claim, confirm coverage with your insurer and review the roofing contract separately.
Keep the signed scope, change approvals, inspection records, photographs and warranty documents together.

Elena receives competing estimates for a roof replacement. One leaves flashing and damaged decking unexplained. She asks every bidder to clarify those items and document insurance. She chooses a roofer whose revised contract explains the work, additional-cost approval and cleanup, with payments tied to progress.
