Start with the middle bid and make the other two explain themselves. That is the plain answer for a first-time buyer holding three quotes from roofing companies Middletown RI neighbors keep naming, where the numbers run from around nine thousand dollars to twenty-two thousand on the same house. The spread is not proof that somebody is cheating you. It usually means three crews priced three different jobs, and only one wrote down what they actually intend to do up there.

Vetting matters more than it did a few years ago. A July 2026 Moneywise report carried by Yahoo Finance cited National Insurance Crime Bureau figures showing contractor fraud reports jumped nearly 40% between 2023 and 2025. That does not make your low bidder a criminal. It does mean the burden of proof sits with the contractor, not the homeowner.

Read the scope lines before you read the totals. One bid may quote a tear-off, which simply means stripping every old layer down to the bare wood deck, while another quotes an overlay that nails fresh shingles straight over the existing ones. Add plywood replacement where the deck is soft, drip edge, ice and water barrier along the eaves, ridge vent, and the two numbers separate quickly. Say the middle bid on that East Bay house lands at $14,800 with a complete tear-off, while the nine thousand dollar quote covers shingles, nails and two days of labor. Same roof. Two different products.

Do not climb up there to settle the question yourself. Falls to a lower level killed 389 construction workers in 2024 out of 1,034 construction deaths overall, which is why OSHA runs fall protection as its top construction hazard campaign and why a wet or storm-damaged roof belongs to a licensed, insured crew with harnesses. Ask each estimator to photograph what they found instead. The one who did that without being asked is telling you something.

Three documents settle most of this, and they cost nothing. Ask for the state contractor registration number and verify it with the licensing board, not the letterhead. Ask for a certificate of liability and workers’ compensation coverage sent straight from the insurance agent. Then ask what the workmanship warranty covers and whether it transfers when the house sells, because a manufacturer’s shingle warranty and an installer’s labor warranty are two separate promises, and after a leak it is the labor side that decides who pays.

Warranty language is where a thin bid gives itself away. A ten year transferable workmanship warranty from a company that has held the same registration for two decades is a different asset than a one year handshake from a crew that formed last spring. The bid that explains the least is the one you understand the least, and that is exactly what you would be signing. Ask how many installs from five years back they have returned to fix, and listen if the answer is zero.

Salt air is the variable out-of-town bidders underprice. Coastal exposure wears a shingle roof down faster than the brochure life span suggests, and Money reported that S&P Global Market Intelligence puts asphalt shingle life expectancy at 10 to 12 years in Florida versus about 20 years elsewhere. Rhode Island is not Florida, though salt and wind-driven rain push the number the same way. The case we see most often in these comparisons is a low quote that prices shingles carefully and treats the metal work as an afterthought. A roof with skimped flashing is on borrowed time.

Here is what nobody can tell you honestly: there is no clean published figure for how many residential roof leaks trace back to bad flashing rather than bad shingles, because the evidence gets torn off and hauled away before anyone records it. Contractors will each quote a confident percentage and they will not agree. What you can check is whether each bid lists step flashing at the wall lines, counter flashing at the chimney, and a new boot on every pipe. Absent from the page usually means absent from the price.

The decision comes down to who picks up the phone in year three. Search results for roofing companies Middletown RI will hand you a list of names, and the list is not the work; a contractor forty miles out is a different proposition than an owner who drives past your street. Pick the bid you can read line by line, from a registered and insured installer who put the tear-off, the underlayment, the flashing and the warranty in writing, then hold that company to every line. If that turns out to be the middle number, pay it.
