Recent construction material price increases can be a reason to recheck a roof replacement quote. They do not tell you how much your quote should change. A broad market index cannot see the products, quantities, labor, scope, or timing in one contractor's proposal.
If your quote has been revised, ask for the exact changed line and amount in writing. Then compare the same job. Remi's guide to deciding whether a roof price is fair covers the broader price check, while the roof estimate guide covers the full written scope.
What changed in the July 2026 price report?
The National Roofing Contractors Association reported that overall construction input prices rose 0.1% in July 2026 and 7.4% over the prior twelve months. Within that report, softwood lumber was up 15.0% year over year and iron and steel was up 17.6%. Read the NRCA update. (opens in a new tab)

NRCA reported these producer-level construction input changes on August 18, 2026. They are not changes to a specific homeowner's installed roof price.
Those figures are useful context for a new or aging quote. They show that some construction inputs have moved. They do not identify a product, quantity, purchase date, or dollar line in your proposal.
Why 7.4% is not your roof-quote increase
The Bureau of Labor Statistics says the Producer Price Index measures average changes in selling prices received by domestic producers. That is an earlier point in the pricing chain than a complete roof replacement sold to a homeowner. See what the Producer Price Index measures. (opens in a new tab)
The PPI statistic and your written quote are different records. One describes average producer-price changes. The other states a price for a defined scope. Adding 7.4% to the quote would assume a direct relationship the index does not establish.
What the report cannot confirm about your estimate
The NRCA update does not connect its lumber or steel percentages to a product, quantity, purchase date, or dollar line in your quote. Do not assign either percentage to your proposal without documentation from the contractor.
If the contractor cites a material increase, ask for the exact line and the amount before and after the revision. If the scope also changed, ask for that change to be documented separately. This keeps the comparison tied to the written proposal instead of a market headline.
Four questions to ask about a revised quote
- 1What date and validity period are on the quote? Check the document itself. Do not rely on a universal rule of thumb.
- 2Which exact line changed? Ask for the named product, quantity, or scope item rather than a general inflation explanation.
- 3What was the amount before and after the revision? This keeps a material adjustment from quietly changing unrelated parts of the job.
- 4How will later changes be documented? Ask what happens if the contractor identifies an additional scope item after work begins.
The Federal Trade Commission advises homeowners to get three written estimates and a written contract. That makes a written revision the cleanest way to compare the new number with the original scope. Read the FTC home-repair guidance. (opens in a new tab)
Compare the same roof before accepting a new total
Put the original and revised quotes side by side. Confirm that the listed products, quantities, scope, warranties, and payment terms still match. If the scope changed too, separate that difference from the material price adjustment.
If you are comparing two contractors, line up both the date and the scope before judging the totals. One newer quote may use current supplier pricing while the older quote needs confirmation. One may also include work the other leaves out.
A lot of roofers charge extra for plywood replacement, not Remi.
Michael's review describes one project, not a reason another quote changed. Confirm decking allowances and revision terms in your own written proposal.
Frequently asked questions
No. The 7.4% figure covers a broad group of construction inputs at the producer level. It does not show the material mix, labor, overhead, scope, or timing in your roof quote. Ask for an updated written quote instead of applying the index yourself.
Ask the contractor to identify the product, quantity, or scope line that changed and show the revised amount in writing. Also check the quote date, any stated validity period, and how unknown conditions will be documented.
No. Those percentages describe broad producer-level categories, not the products, quantities, purchase dates, or dollar lines in your proposal. Ask the contractor to connect any revision to the actual quote in writing.
Confirm that both prices are still current, then compare the same materials and scope. If one contractor changed a price, ask for the reason and amount in writing before comparing the totals.
