Is the cheapest roof quote a red flag?
Nobody wants to overpay for a roof, and nobody wants the roof that has to be done twice. The low quote is where those two fears meet.
Not by itself. A lower price is legitimate when the contractor has lower overhead, is filling a schedule gap, or genuinely measured a simpler scope. It becomes a red flag when the gap is unexplained and the quote is missing the things that cost money: tear-off, disposal, new flashing, a decking rate, licensing, and insurance. Check those four things and the low quote tells you which kind it is.
01 /When cheap is just cheap
There are honest reasons one number comes in lower. A smaller outfit without a showroom or a sales team carries less overhead. A crew with a gap in the schedule may price to fill it. A contractor who measured a simpler scope, or who is quoting a basic shingle line rather than a premium system, is quoting a different product at a fair price for that product.
None of that is a warning sign. What matters is whether the difference is explainable when you ask.
02 /The four checks
- License. Most residential roofing work in Michigan requires a licensed residential builder, and license status is public. Run it yourself through Michigan LARA's Verify a License lookup.
- Insurance. Ask for the certificate of insurance, and ask whether it covers general liability and workers compensation. If somebody is hurt on your property and the contractor has no coverage, that exposure can land on you.
- Written, itemized scope. Tear-off or re-cover, square count, underlayment and ice barrier, which flashing and vents are new, the per-sheet decking rate, and the exact shingle line. A number on a business card is not a quote.
- Payment terms. A reasonable deposit with the balance on completion is normal. Full payment up front is not, and it is the single most common feature of jobs that never get finished.
The classic bad-outcome sequence is a large up-front deposit, a vague one-page quote, and a contractor who is difficult to reach afterward. Michigan Attorney General consumer protection resources cover home repair complaints and how to report them.
03 /What a fair number looks like here
For reference while you compare, our published Macomb County asphalt replacement range is $9,000 to $18,000, with most homes between $12,000 and $16,000. A quote far below that band on a full replacement is not automatically wrong, but it should come with an explanation you can point to in writing: a smaller roof than you thought, a re-cover instead of a tear-off, or a more basic material package.
If the explanation is just that they are cheaper, that is the moment to run the four checks above rather than to sign.
The extended list, including the specific contract language worth insisting on, is in the full red flags guide.
The follow-up questions
There is no fixed percentage, because scope explains most gaps. The better test is whether the difference can be traced to something specific: fewer squares, a re-cover instead of tear-off, reused flashing, or a more basic shingle line. An unexplained gap of thousands on identical scope is the one worth investigating.
No, and a legitimate contractor will not treat it as rude. License status is public record in Michigan and a certificate of insurance is a routine document that contractors produce constantly. Hesitation or friction around either request is itself information.
A modest deposit to secure materials and a schedule slot is normal practice, with the balance due on completion. Full payment before work begins is not standard and removes your only real leverage if something goes wrong. Get whatever is agreed in writing in the contract.
