Roofing material prices moved again. Your price list didn't.
Manufacturer increases arrive with an effective date, and they land mid-season. The expensive part is rarely the increase itself. It is the weeks your quotes keep going out priced from the old list.
Manufacturers raise prices with an effective date, and the date lands wherever it lands. Often mid-season, when the office is busiest and nobody has an afternoon spare.
The increase itself is not usually the expensive part. The expensive part is the stretch between the day the new cost takes effect and the day your price list catches up, because every quote that goes out in that window is priced from a number that is no longer true.
What changed, stated carefully
Material costs have risen, tariffs on imported steel and aluminum raised input costs for metal products, and manufacturers have announced increases through distribution. Those are matters of public record.
What we are not going to do is give you a percentage, and it is worth saying why, because it is the more useful part of this post.
When we went looking for the 2026 figures, nearly everything we found was a roofing company's marketing page or a tariff explainer citing another one. A national average replacement cost quoted to the dollar with no survey behind it. A per-material breakdown with no manufacturer letter attached. One figure claiming asphalt roofing products are up more than 58 percent since 2019, which sounds like federal producer price data and which we could not confirm against the federal producer price series.
We publish numbers when we can point at where they came from. On this topic, as of August 2026, we could not, so we are not going to invent precision. Your own distributor invoices from January and from last week are better data about your market than any national figure, and you already have them.
Where the money leaks
A price increase becomes real to a roofing company at four separate moments, and they do not happen together.
The announcement arrives, to whoever opens the mail from your distributor. The effective date passes. Then quotes keep going out, priced from whatever list your estimating runs on, because that list is a file and files do not update themselves. Finally the job closes, the material comes off the truck at the new price, and the margin turns out to be a number nobody chose.
The gap between the second and third of those is where the money goes. It is invisible while it is happening, which is the whole problem. Nothing in the quoting process announces that a price is stale.
The arithmetic, with your numbers
There is no industry figure for this and there does not need to be, because you can do it in five minutes with numbers you already have. What follows is our arithmetic rather than anyone's research.
Count the quotes you send in a normal week. Multiply by the number of weeks between an effective date and the day your price list actually changed. That is the number of quotes that went out mispriced. Apply your close rate and you have the jobs you sold at last month's cost.
Owners guess that second number low, consistently. The effective date is easy to remember. The day the spreadsheet finally got updated is not, so the honest way to find it is the file's modification date rather than anyone's recollection.
Why the list is always late
Because updating it is a job, and jobs that take a day get scheduled behind jobs that take an hour.
Where the price list is a spreadsheet, re-pricing means opening it, changing costs line by line, checking that the formulas underneath still point at the cells they used to, and then telling everybody the new version is the real one. That last step fails quietly. Someone keeps quoting from the copy on their desktop.
Inside a quoting tool it is better, because there is one copy. It is still a person going through a list, and it still competes with a full week.
The design question worth asking is not how fast your team can retype a price list. It is whether cost is a number stored in one place that everything else reads, or a number copied into a hundred places that each need visiting.
What to do about it now
Find the modification date on your current price list. That single fact tells you whether this post describes you.
Then separate cost from price. If your quoting holds a material cost and applies your markup, waste and minimums as rules on top, a new distributor cost is one edit. If your quoting holds finished prices with the markup already baked in, every change is a rebuild, and that is why it keeps being late.
Finally, put the effective date somewhere the office will see it. A price increase with a date three weeks out is a manageable thing. The same increase discovered when the invoice arrives is not.
Frequently asked questions
Why do roofing material prices keep changing mid-season?
Manufacturers announce increases with an effective date rather than at a fixed point in the year, and those dates fall wherever they fall. Tariffs on imported steel and aluminum have also raised input costs, which reaches metal products most directly.
How much have prices gone up?
We are not going to give you a percentage. The figures circulating for 2026 come almost entirely from marketing pages citing each other rather than from manufacturer announcements or federal price series, and a number you cannot check is worse than no number. Your own distributor invoices are the reliable source for your market.
What is the real cost of a price increase to a roofing company?
Usually the lag rather than the increase. Between the effective date and the day someone updates the price list, quotes continue going out at the old cost, and any of those that get signed are sold at a margin nobody chose.
How do I work out what a lag is costing me?
Take the number of quotes you send in a week, multiply by the weeks between the effective date and your price list being updated, and look at how many of those closed. That is our arithmetic rather than an industry figure, and it is the only version that uses your numbers.
How often should a price list be updated?
Frequently enough that updating it is not an event. If re-pricing means one person working through a spreadsheet for a day, it will happen late. If it means changing costs in one place and having every quote pick them up, the effective date stops mattering.
