Reading a Roofing Quote (and What the Cheap One Leaves Out)

By Chesapeake Roofing Pros · October 21, 2026 · 8 min read

Picture three quotes on the kitchen table for the same roof in Great Bridge: $11,800, $14,200, $15,600 (an illustrative example, but a familiar spread). Most people assume the middle one is right and the low one is a bargain. What's usually true is that they're quotes for three different roofs. A good roof estimate in Chesapeake names every layer and every line, and the cheapest one is often cheapest because of things you won't see until it leaks.

Here's how to read them, line by line.

What a roofing estimate in Chesapeake should include

A real estimate is one or two pages. Go down each quote and check for these:

1. Tear-off and disposal. Full removal of the existing roof down to the deck. If a quote is quiet about this — or mentions "overlay" or "re-cover" — it's a roof-over. Whether one is allowed on your house is a question for the City of Chesapeake, and near the coast it's a bad idea anyway: the old shingles hold moisture against the deck, the new ones sit on a lumpy surface and don't seal well in wind, and nobody has looked at the plywood.

2. Decking. A per-sheet price for replacing bad plywood, usually $90–$150, and a stated number of sheets included (often zero or one). That's the decking allowance, and it's the line that decides what you actually pay. "Decking as needed" or "additional charges may apply" means the surprise comes on the last day. On a 1980s Greenbrier house that's had a valley leak, that surprise can be eight sheets.

3. Underlayment. Synthetic, by name. On synthetic underlayment vs felt, the felt is about $150 cheaper on a whole roof, wrinkles in Chesapeake humidity, and tears in wind before the shingles go on.

4. Ice-and-water membrane. Where, exactly: valleys, around every penetration, along the eaves, and at wall transitions. Whether code requires it at the eaves is something to confirm with the City of Chesapeake; either way, the low quote often skips it. Wind-driven nor'easter rain gets under the first course of shingles much the way ice does farther north.

5. Shingle product and wind rating. A named line — not "30-year architectural" — with its ASTM D7158 class. Class H is rated to 150 mph and is what belongs on a roof in Hampton Roads. Class F is 110 mph. If the quote doesn't say, ask.

6. Nailing. Six nails per shingle. It's on the shingle wrapper as the high-wind pattern, and it can decide whether the manufacturer's wind coverage applies. Four nails is faster, and it's what the low bid often assumes.

7. Starter strip and drip edge. A starter strip with its own adhesive along the eaves and rakes — not cut-down shingles — and new metal drip edge. Rakes are where wind gets under the roof edge first.

8. Flashing. New step flashing at every wall, new counter-flashing at the chimney, new pipe boots, new vent caps. A quote that reuses 25-year-old flashing is saving $400 on the part of the roof most likely to leak.

9. Ventilation. Ridge vent cut in, soffit vents checked. Cheap to add now, expensive to add later.

10. Permit. A re-roof in Chesapeake generally needs a city building permit — confirm with the City of Chesapeake's permits office and ask your roofer who pulls it and whether it's in the price. If the quote doesn't mention it, ask before you sign.

11. Cleanup. Tarps on landscaping, a dump trailer, and a magnet sweep for nails. Ask what happens to the pool and the AC unit.

12. Warranty. Two lines: the manufacturer's material warranty in years, and the workmanship term. Get the workmanship term in years, in writing, from the roofer who installs it.

13. Squares. The roof measurement. If one quote says 26 squares and another says 31 for the same house, one of them measured wrong, and the per-square price is meaningless until you know which.

Roof quote comparison: what the cheap one usually left out

Take a low quote apart and it typically looks like this:

That's $1,700–$3,100 of roof that isn't in the low number. Add the decking on invoice day and the quotes converge — except one roof has felt and reused flashing.

Two things that aren't on the paper

Who's doing the work. Ask whether the crew is the company's own or a subcontractor found that week, and who supervises. Whether anyone went in the attic. A quote from a satellite measurement without an attic look hasn't seen the ventilation, the decking, or the leak trail.

What to do with three quotes

Put them side by side against the list above. Ask each roofer for the lines that are missing. The company that adds them and re-prices is worth talking to. The one that says "we don't do that here" has told you what you needed to know. If you want more than two or three roofing estimates in Chesapeake, VA, you're usually better off asking the ones you have to fill in the gaps than collecting a fourth. The roof replacement page lists what a full replacement should include, and the cost page has the ranges each of those lines should land in. Our post on questions to ask a roofing contractor covers the license and insurance side.

Mistakes people make comparing a roofing quote

• Comparing the bottom line first. Totals only mean something once the scope matches. Read the lines, then the price.
• Ignoring the square count. A bid that measured five fewer squares will look cheap and then grow on invoice day.
• Accepting "or equal" on materials. If the shingle line says "or equal," ask which product will actually arrive in the driveway.
• Taking verbal promises. "We always do six nails" means nothing unless the paper says it. Anything you were told on the driveway belongs in writing.
• Signing the same day. A sales visit that pushes a same-day price is a reason to slow down, not speed up.

A five-step way to compare quotes

1. Write the thirteen lines above down the left side of a sheet of paper.
2. Put each quote in its own column and mark what each one includes, leaves out, or leaves vague.
3. Send each roofer the same short list of gaps and ask for a revised price.
4. Check the square counts against each other. If they disagree by more than a square or two, ask how each one measured.
5. Only then compare totals, and set aside room for decking beyond the included sheets.

Questions to ask before you sign

• Which of these lines is an allowance, and what does it cost if you go over it?
• Who pulls the permit, and is the fee in this price?
• Will someone go into the attic before the price is final?
• What happens if it rains halfway through the tear-off?
• Who do I call about a leak after the job, and is that in writing?

Common questions

What should a roofing estimate include?

Tear-off, decking allowance with a per-sheet price, the underlayment by name, ice-and-water membrane locations, the shingle product and wind class, the nailing pattern, starter and drip edge, new flashing and boots, ventilation, permit, cleanup, warranty terms in years, and the number of squares. If a line is missing, ask for it in writing before you compare prices.

Why is one roof quote so much cheaper than the others?

Usually because it's a different roof. The low bid tends to use felt instead of synthetic, skip membrane at the eaves, reuse flashing, assume four nails, and leave decking open-ended. Sometimes it also measured fewer squares. Line the quotes up item by item and the gap usually explains itself.

What materials are needed to replace a roof?

On a typical Chesapeake shingle roof: replacement plywood where the deck is bad, synthetic underlayment, ice-and-water membrane, drip edge, starter strip, architectural shingles, ridge cap, step and counter-flashing, pipe boots, vent caps, a ridge vent, and roofing nails. A complete quote names each one.

Should a roof quote include the permit?

It should say clearly whether it does. A re-roof here generally needs a city building permit, so ask who pulls it and whether the fee is in the price. Confirm the current rules with the City of Chesapeake's permits office rather than relying on any one roofer's answer.
