Buying a House? How to Evaluate the Roof Before You Close

  • Published November 7, 2026

Under InterNACHI’s standard of practice, a home inspector may judge the roof from the ground or the eaves without walking it, predicting its remaining life or confirming how it was fastened. Close that gap before your inspection contingency expires: get the seller’s roof records, add a roof specialist when the report shows limits, and get an insurance quote that states how the roof will be covered.

Every step below runs on the same clock. Write the contingency deadline at the top of a page, then work backward: documents first, because they decide whether you need a specialist, and the insurance quote in parallel, because an older roof may have to pass the insurer’s own inspection before you get a firm answer.

What the Home Inspection Leaves Out on the Roof

The roof section of the InterNACHI Home Inspection Standards of Practice, in its October 2022 revision, has the inspector “inspect from ground level or the eaves.” It also lets the inspector skip what a buyer might assume was done: walking the roof, predicting how long it will last, and confirming that the covering was fastened and installed properly. Other inspector associations and some states publish their own standards, and their roof scope may differ, so ask your inspector which standard they follow.

None of that makes the home inspection weak. It means the roof section answers a narrower question than the word “inspection” suggests: what can be seen from where the inspector stood. Read the roof section for its method line first (“observed from ground,” “inspected with drone,” “walked”) and then for its findings. For a full walk-through, see how to read a roof report’s sections and limitation lines.

Three things the report may not tell you, even when it is thorough:

  • How old the roof is, and how anyone knows.
  • Whether the shingles were nailed and sealed the way the manufacturer requires.
  • How an insurer will treat the roof when you apply for a policy.

Roof Documents to Request Before the Contingency Deadline

Send the request in writing through your agent on the day the contract is signed. Ask for copies, not descriptions:

  • Installation date proof: the roofing contractor’s invoice, the building permit and its final inspection, or a warranty registration. How to find out how old a roof is explains which record carries the most weight.
  • Contractor name and license number, so you can confirm the company existed and, where your state or city licenses roofers, was licensed when the work was done.
  • Warranty documents for the shingles and the workmanship, and any paperwork about transferring them. Manufacturer warranties can set their own transfer steps and notice windows; see transferring a roof warranty before the deadline passes.
  • Repair invoices for leaks, storm repairs or flashing work, with dates.
  • Any roof insurance claims the seller filed: the date, what was paid, and whether the repair or replacement was actually completed.
  • Earlier inspection reports, including any from a previous sale or refinance.

Whether your state requires a seller disclosure form, and what it asks about the roof, varies by state, so ask your agent which form applies and read every answer that touches the roof, leaks or repairs. A blank or “unknown” answer is not an answer; follow up in writing.

When to Add a Roof-Specific Inspection

A roofer or roof specialist can add what the home inspection is not required to do: walk the roof where it is safe, check fastening and flashing up close, and look for soft decking. Add one if any of these apply:

  • The report says the roof was viewed only from the ground or not inspected because of height, pitch or weather.
  • The roof’s age is unknown, or the documents conflict.
  • The attic shows water stains, damp insulation or daylight through the deck.
  • The report mentions curling, missing shingles, granule loss, sagging or more than one layer.
  • The roof is tile, slate, metal or low slope, and the inspector did not inspect it closely.
  • The seller filed a roof claim and cannot show the work was finished.

The exception is a recent roof with a permit, an invoice and warranty papers in hand. That roof may need no specialist if the home inspector saw nothing of concern.

Book the specialist early in the contingency window. Ask them to put three things in writing: the method used (walked, ladder, drone), photos of each finding with its location, and which findings are roof-wide versus local.

Get an Insurance Quote That States the Roof Terms

An insurance quote is roof evidence you can get without climbing anything. Insurers look hard at older roofs: an Insurance Information Institute explainer on roofs and insurance says most insurance companies will require a roof over 20 years old to pass an inspection when you apply, and some may cover it only at actual cash value (ACV). That is an industry summary, not a rule every insurer follows.

The Texas Department of Insurance’s guide to insurance and your roof, last updated April 1, 2026, makes the same point from the regulator’s side: some policies pay less for a roof that is older or worn, and some companies move aging roofs to actual cash value. In the definitions of the NAIC’s consumer’s guide to home insurance, ACV pays the roof’s value after age and wear are taken into account, while replacement cost (RCV) pays to repair or replace it with materials of similar kind and quality, so the gap between the two widens as the roof ages.

Ask the agent or insurer in writing:

  1. Will the roof be covered at replacement cost or actual cash value?
  2. Does the policy include any endorsement or schedule that changes how roof claims are paid by roof age or material?
  3. Will the insurer require a roof inspection before binding coverage, and who orders it?
  4. Is there a separate wind or hail deductible, and what is it?

Then read the quote’s declarations page and any roof-related endorsement it lists. If an insurer declines the property or will cover the roof only at ACV, that is a finding to negotiate on, just like a specialist’s report. Rules on roof-age underwriting vary by state, and your state insurance department can tell you what insurers there may do; the NAIC’s list of state insurance departments has contacts for each. For how insurers apply roof age, see roof schedules, insurer inspections and other roof-age rules.

Turn Roof Findings Into a Repair, Credit or Price Request

Put every roof ask in writing, attach the evidence (report pages, photos, the insurance quote), and tie it to a written estimate from a licensed roofer. Each option shifts control differently:

  • Seller repair before closing: the seller picks the roofer and the scope. If you take this route, require a licensed contractor, a permit where your jurisdiction requires one, a final invoice, and warranty documents in a form that can pass to you. Ask for photos of the finished work.
  • Credit at closing: you control the roofer and the scope after closing. Ask your lender in writing whether a credit is allowed and how it must be handled, because loan programs and lenders can limit seller credits.
  • Price reduction: simplest on paper, but it lowers the price rather than putting cash in hand for the work.

Layer count changes the size of the fix. In Lincoln, Nebraska, for instance, a roof with two or more layers must lose all of them at re-roofing, under a city re-roof policy drawn from the 2018 International Residential Code (IRC). Where you are buying, the rule depends on the code edition and local amendments that building department enforces; see overlay versus tear-off for how layer limits work.

Should the Roof Change Your Offer?

If the documents are complete, the inspection found no roof-wide wear, and the insurance quote covers the roof at replacement cost, the roof should not change your offer. Keep the records for your own file.

If any one of those three fails, get the specialist’s findings and a written roofer’s estimate, then ask for a repair, credit or price change sized to that estimate, and send the request before the contingency expires. If you cannot get the specialist report or the insurance answer in time, ask in writing for a short extension of the inspection contingency rather than waiving it.

If you are using an FHA or VA loan, the appraisal adds its own roof question; see what FHA and VA appraisers check on the roof and ask your lender which wording applies.
