The Takeoff The estimate

Ask What a Declined Roof Line Would Have Cost

When you turn down a gutter, skylight or chimney cap on a roof quote, ask what that line would cost as a separate job later.

A roof quote usually has a few lines you can turn down. A skylight you could leave in place, a gutter run you could skip, a chimney cap you think you can live without, a ventilation upgrade the roofer calls optional. Each no lowers the total on the page. What most homeowners do not ask is what the same line costs if they say yes later, by itself, after the new roof is on.

That number matters because a no today is not always a no for good. Saying no on the estimate date is a budget decision. Saying no after the tear-off starts is a decision made with the crew standing on your roof, and the price for a late yes can differ from the price on the page. The only way to see the difference before you sign is to ask for the declined price in writing.

Why the declined price is a separate question

Most roof bids are built as one job. The crew, the dumpster, the disposal and the install share a schedule, so a line removed from that schedule changes more than its own cost. A skylight that is left alone still has to be worked around, flashed or sealed. A gutter run that is skipped still meets the eave edge where the new shingles end. The quote may show a clean subtraction, but the work on the other lines may not drop by the same amount.

That is why you ask for two numbers. The first is the change to this quote if the line comes off. The second is the price for the same line as a separate job, done later by the same roofer or a different one, with the roof already on. If the two numbers are far apart, you have learned something about how the bid was built. If they are close, the choice is simpler.

Three lines that come up on St. Louis roofs

A skylight is the clearest case. If the opening stays, the crew works around the frame, reflashes the curb and reseals the glass edge in the same visit. If you decline a skylight replacement and then want it later, the work becomes a second trip to the roof, with its own ladder, staging and cleanup. The flashing around the opening may need to be lifted off shingles that are already in place. Ask the roofer to price the replacement on its own and to say whether it carries its own trip charge.

Gutters follow the freeze and thaw cycle. A St. Louis winter puts repeated loads on fascia and on the hangers that hold a run to it. Some homeowners decline gutters on a roof replacement because the old run looks fine from the ground. Later, a loose run or a sagging section means a ladder crew at the eave, and the new shingles at the edge may need to be lifted to reach the fascia. Ask what a full run costs as a separate job, and ask whether that price includes fascia repair if the boards are soft.

A chimney cap is smaller in dollars but easy to skip. The cap sits on top of the flue, and on a roof with new shingles the crew may be working right beside it. Declining the cap during the roof job often means a separate visit later to reach the top of the chimney. Ask whether the cap can be set during the roof job at a lower added price, and what it would cost as a standalone visit.

Reading the two numbers side by side

Put the two figures on one line. The first is the drop in the current quote. The second is the separate price. If the drop is much smaller than the separate price, the roofer may have spread part of that cost across other lines of the bid, or the separate job may carry costs the bid did not show. Either can be legitimate, but you should be able to see which one applies. Ask the roofer to explain the gap in one sentence. If the answer is that the crew must mobilize twice, check that against the trip line on your quote. If the answer is vague, ask again in writing.

If the drop is larger than the separate price, the question runs the other way. The bid may be carrying a cost that disappears when the line is removed, which is a reason to ask whether the remaining lines still reflect the work you will get. Neither result tells you whether to say yes or no. It tells you what the choice actually costs, so the decision rests on a number instead of a guess.

What the declined-line number should include

A separate price is only useful if it is complete. Ask the roofer to state, in writing, the labor, the materials, the disposal, any trip or fuel charge, and the permit fee if one applies in your city or in the county where you live. Ask whether the price assumes the roof is still on the house or whether it assumes a fresh tear-off around that spot. Those are different jobs, and they can carry different numbers.

Ask how long the price holds. A number for a skylight that is only good for thirty days may not match the price of a skylight you decide on next spring. Ask the roofer to name what would move the number, such as a change in material, a price increase on the shingles, or a delay that pushes the work into colder weather when sealing and staging take longer.

What to ask before you sign

  • What is the total on this quote if I remove the skylight, the gutter run and the chimney cap, one at a time?
  • What is the price for each of those three lines as a separate job, done after the roof is finished?
  • Does each separate price include a trip charge, disposal, and any permit fee?
  • If the skylight stays, what work does the crew still do around it?
  • How long does each declined-line price hold, and what would change it?
  • Can you put all of these answers in the written estimate before I sign?

Keys will measure your roof and produce the same document properly: square count, measured pitch, expected layers, decking unit rate, the assembly from the deck up and the penetration list. Put the two side by side. Where they disagree on a quantity, one of them has not been on your roof, and you will be able to see which.

If you would rather talk it through, this is the office line and not a call centre.
