Key Takeaways
- The lowest quote by a wide margin is rarely the right call. Roofing is close to a fixed-cost trade, so a much lower price almost always means lighter value, not a better deal.
- A cheap number is reached by cutting something — thinner shingles, reused flashing, skipped ventilation, no permit, or a weak warranty.
- Those cuts show up later as leaks, premature failure, and voided warranties — often within a few years, and usually for more than the money you saved.
- The fix isn’t to always pay the most. Level the quotes to the same scope, then pick the best price among roofs that actually match.
Should you hire the cheapest roofing contractor?
Usually not — at least not when one quote sits far below the rest. A roof is one of the larger purchases you’ll make on your home, and the lowest bidder is almost never offering the same roof for less. They’re offering a different, lighter roof at a price that reflects it. The goal isn’t to chase the lowest number or automatically pay the highest one. It’s to find the best value, then the best price within it.
Why is roofing close to a fixed-cost trade?
Asphalt shingles, underlayment, ice-and-water shield, flashing, and the disposal of your old roof cost about the same for every reputable contractor buying from the same suppliers. Honest, experienced labor costs roughly the same too. In Massachusetts, roofing labor runs about 15% above the national baseline — but that applies to every contractor quoting your roof, so it can’t explain why one bid is thousands less than the others.
Because the real costs don’t move much, a much-lower price has to come from somewhere. It comes out of the materials, the scope, or the protection behind the work — which is exactly why two quotes for the same roof can land so far apart. We unpack that gap in detail in why two roofing quotes for the same roof are so different.
What does a cheap roofing quote usually cut?
When a price comes in well under the others, the savings are almost always one or more of these:
- Thinner materials — a builder-grade three-tab shingle instead of a premium architectural line, or felt underlayment instead of synthetic.
- Reused flashing — the old metal put back instead of replaced, at the most common leak point on the roof.
- Skipped ventilation — no intake-and-exhaust upgrade, which shortens the roof’s life and can void the manufacturer warranty.
- No permit — skipping the permit also skips the town inspection, and can stall a future home sale. A licensed contractor pulls it as a matter of course; the licenses and insurance a Massachusetts roofer should hold are part of what you’re paying for.
- A weak or missing warranty — a short workmanship term, or none in writing.
- A planned upcharge — a low headline number with “unforeseen” decking repairs the contractor already expects to bill you for once the old roof is off.
Find what the cheap quote left out
Our Quote Comparison Tool lines up your estimates so the gaps behind a lower price — the unnamed shingle, the reused flashing, the missing permit — are easy to see before you decide.

The savings are immediate; the bill comes later. Reused flashing fails at the chimney and lets water into the ceiling. No ice-and-water shield means an ice dam drives water back under the shingles and into the walls. Poor ventilation cooks the shingles from below, ages them early, and can void the manufacturer warranty you thought you had. An unpermitted roof can surface as a problem when you sell.
These aren’t rare outcomes — they’re the predictable result of the specific things that got cut to reach a low number. And the repair usually costs more than the money saved, because you’re paying a second crew to fix what the first one skipped.
“A price with nothing behind it isn’t a bargain. We’ve been called to roofs that were a few years old and already leaking — reused flashing, no ice-and-water shield. The homeowner saved a little up front and paid for two roofs instead of one.”

How do you choose without overpaying?
Avoiding the cheapest roof doesn’t mean buying the most expensive one. It means comparing roofs that actually match:
- Level the quotes. Ask every contractor to describe the same materials and scope — the same shingle line, synthetic underlayment, new flashing, a real ventilation plan, the permit, and cleanup. That’s exactly what a complete roofing estimate should include.
- Then compare price. Once the roofs match, the price difference reflects crew quality, warranty depth, manufacturer certifications, and the company’s track record.
- Pick the best value, not the lowest line. Among matched quotes, the most affordable can be a smart choice. It’s the unmatched low bid — the one that’s cheap because it’s less roof — that you walk away from.

Frequently asked questions
Should you hire the cheapest roofing contractor?
Usually not, if it’s the lowest by a wide margin. Roofing is close to a fixed-cost trade, so a price well below the others almost always means something was cut — thinner materials, reused flashing, skipped ventilation, no permit, or a weak warranty. Compare value first, level the quotes, then choose the best price among matched ones.
Why is one roofing quote so much cheaper than the others?
Because it’s buying a lighter roof. A quote 30% below the rest usually leaves things out — a builder-grade shingle, felt instead of synthetic, reused flashing, no ventilation upgrade, no permit, or a short warranty. Sometimes the low number is a plan to upcharge you for decking repairs the contractor already expects to find.
Is a cheap roof a bad investment?
A roof priced well below honest market value usually costs more over its life. Cut corners show up as leaks, premature failure, and voided warranties, often within a few years. A fairly priced, complete roof that lasts its full term is almost always the cheaper choice over the time you own the home.
How do you compare roofing quotes fairly?
Make every quote describe the same roof first, then compare price against value — crew quality, warranty depth, certifications, and track record. The cheapest of three matched quotes can be a fine choice; the cheapest of three unmatched ones rarely is.
