Questions to ask a Roofing Contractor

A new roof is one of the larger investments a homeowner can make. The right questions turn a sales conversation into a written plan for protecting the house, managing water, and finishing the job without surprise charges. They also make it easier to spot a contractor who will not document insurance, scope, or warranty terms.

Start by deciding whether the work is a targeted repair or a replacement. Age alone does not answer that question, because the condition of shingles, flashing, decking, and attic moisture all matter. This guide to roof replacement warning signs can help frame that first discussion. Then use the questions below to compare written answers, not sales promises.

What proof of licensing, insurance, and permits should a roofer provide?

A credible contractor should provide current documents and identify who will obtain the required permit before work begins. Licensing rules, permit triggers, and inspection requirements are set locally, so there is no single national roofing license. The Federal Trade Commission’s article “How to Avoid a Home Improvement Scam” advises consumers to check licensing and insurance and to get contract details in writing.

• Can you provide certificates of general liability and workers’ compensation insurance that I can verify? Ask for the insurer’s contact information and policy dates, then verify coverage directly. General liability addresses certain property-damage claims. Workers’ compensation coverage is a separate question tied to injuries to employees. A verbal assurance or an expired certificate does not establish current coverage.
• What local or state license applies to this project, and what is the license number? Look for an answer that identifies the relevant jurisdiction and gives you a number to check with the licensing authority. If a location does not license roofers, the contractor should say so plainly rather than implying that a generic registration is a roofing credential.
• Will you pull the building permit, and is the permit cost included in the written price? The contract should say who files, who pays, and whether inspections are expected. Avoid an arrangement that asks you to pull the permit solely to bypass a contractor’s responsibility for the stated scope.
• Who will be on site, and will subcontractors be used? Get the legal business name of the contracting party and an answer about supervision. This gives you a clearer record of who is responsible for the work, cleanup, and warranty service.

What should the written scope say about tear-off, protection, and hidden damage?

A useful scope states exactly what will be removed, what will be installed, and how the contractor will handle conditions that cannot be seen until the old roof comes off. A one-line proposal for a “new roof” leaves too much open to interpretation.

• Will you tear off the existing roofing or install a new layer over it? Ask for the proposed assembly in writing. A tear-off exposes the roof deck and existing flashing for inspection. A recover, often called an overlay, leaves the older layer in place and may be restricted by local code or unsuitable for the roof’s condition. The International Code Council’s 2024 International Residential Code roof-assembly provisions address roof recover conditions, but the code adopted by your local jurisdiction controls.
• How will you protect landscaping, siding, windows, and the driveway from falling material and equipment? Look for specific measures, such as ground coverings, plywood where appropriate for a vulnerable surface, and a defined debris route. The answer should also identify who is responsible for magnetic sweeps and final cleanup.
• How will you document and price rotted or damaged decking found during tear-off? The contractor cannot know the full deck condition before opening the roof. Require a unit price or another written method for authorized deck replacement, plus a requirement to show you the condition and obtain approval before adding the charge, except where immediate weather protection is necessary.
• Which flashings will be replaced, reused, or repaired? Ask about roof-to-wall intersections, chimneys, skylights, valleys, vents, and pipe penetrations. Shingles alone do not manage every water transition. The proposal should identify the flashing work rather than burying it in a broad phrase such as “as needed.”

Deck repairs are a legitimate unknown, but they should not become a blank check. A documented approval process separates a necessary change from open-ended scope creep. Dealing with unexpected repairs should be addressed in the documented quote.

Which roofing materials and jobsite details should be specified?

The quote should name the roof system components and explain how they work together on your particular roof. Brand, color, and shingle style are only part of the specification.

What exact shingle, underlayment, starter, ridge product, and flashing materials are included? Ask for the manufacturer, product line, and color where applicable. This lets you compare similar products across quotes and check the manufacturer’s installation instructions. A proposal that names only “architectural shingles” does not identify the materials you are buying.

Which underlayment will be used, and where will a self-adhered membrane be installed? Underlayment choices vary by roof slope, climate, local code, and the shingle manufacturer’s instructions. Ask the contractor to identify standard underlayment, any self-adhered water-shedding membrane, and the locations proposed. The answer should connect the choice to the roof layout rather than presenting one material as a universal upgrade.

Will you evaluate intake and exhaust ventilation as part of the roof scope? Ask for an explanation of the attic’s existing intake openings and exhaust vents, plus whether the proposal changes them. Balanced airflow depends on the attic configuration and clear air paths, not simply on adding more roof vents. If staining, damp insulation, or other moisture evidence is present, review those conditions separately with the concerns covered in this attic moisture problems guide.

How will old roofing be removed and disposed of? A clear answer identifies whether a dedicated dumpster or trailer will be used, where it will sit, and who handles disposal and final site cleanup. Confirm that the proposal includes this work. Disposal arrangements affect access, driveway protection, and the chance that debris remains after the crew leaves.

How should warranties, scheduling, and payment terms work?

Written warranty and payment terms should tell you who stands behind the materials, who stands behind the installation, and when money is due. Keep those obligations separate when comparing proposals.

• What manufacturer warranty applies, and what product registration or installation conditions affect it? A manufacturer warranty generally addresses stated defects in its roofing products, subject to its terms and exclusions. For example, GAF’s published limited warranty documents distinguish product coverage from contractor workmanship coverage. Ask for the actual warranty document that applies to the specified product, not a brochure summary.
• What is your workmanship guarantee, how long does it last, and what does it cover? This is the contractor’s promise regarding installation. Get the duration, covered work, exclusions, claim process, and the business name responsible for service in the contract. A long manufacturer shingle warranty does not automatically pay for an installation error.
• What is the planned start window, expected duration, and weather-delay process? Roofing depends on safe weather and dry conditions appropriate for the materials being installed. A practical schedule explains how the contractor will secure exposed areas if rain interrupts the work and who will update you if the date changes.
• What deposit is due, what milestones trigger later payments, and what changes require written approval? The contract should show dollar amounts or percentages, payment dates, accepted methods, and the final balance. Do not sign a contract with blank spaces or agree to charges that have no written scope. Keep copies of the signed agreement, change orders, permit records, product information, and final invoice.

Before selecting a roofer, confirm the business identity and coverage, permit responsibility, removal method, deck-repair authorization, named materials, flashing scope, ventilation plan, disposal method, workmanship guarantee, manufacturer warranty, schedule, and payment milestones. A contractor who answers these points clearly gives you a proposal that can be checked against the finished roof.

If two written scopes still differ in ways you cannot reconcile, ask each contractor to explain the difference line by line before choosing a quote. For a free, no-obligation discussion please call a listed specialist.

FAQ

Should I get more than one roofing estimate?

Yes, comparing written scopes from more than one contractor is a practical way to find omissions and mismatched materials. Match the tear-off plan, decking allowance, underlayment, flashing, ventilation work, cleanup, warranty, and payment terms before comparing totals.

Can a contractor tell whether the roof deck is rotten before tear-off?

Only visible areas can be evaluated before the existing roofing is removed. A sound proposal explains the preapproved price or authorization method for deck repairs discovered during tear-off, rather than pretending hidden conditions cannot exist.

Is an overlay always cheaper than a full tear-off?

The initial scope may involve less removal work, but price alone does not decide whether a recover is appropriate. Local code, the number and condition of existing layers, roof details, and the need to inspect the deck all affect the decision.

What should I do if a roofer pressures me to sign immediately?

Pause and request a complete written proposal, insurance documentation, and warranty terms. A roof problem may require prompt attention, especially after active damage, but a contract should still identify the work and payment obligations clearly before you sign.
