Buyer's Guide
How to choose a metal roofing contractor in New England
Seven objective checks that work on any company — including us. Apply them to every quote you collect; the differences stop being subtle by check three.
1. Demand documented installs — with addresses, not stock photos
Any roofer can show a photo. The question is whether you can drive past the roof, know when it went on, and see how it's aging. Ask for a mapped install record with job numbers and install years. (Ours is public: 5,012 documented New England installs on the live project map, each with system, color, and year.)
2. Read the warranty like a New England winter is coming
Most roofing warranties prorate sharply after the first decade and exclude ice-dam damage — the region's most common failure. Ask three questions: Is it prorated? Does wind coverage have a mph number in writing? Does it transfer to the next owner, and at what cost? A lifetime warranty with written 120-mph wind coverage and one-time transfer is the standard to hold everyone to.
3. Verify licensing in the state where your house stands
New England is six separate regulatory regimes. A contractor working across the region should hand you state registration numbers without being asked — ours are published in the footer of every page of this site (CT, MA, RI, ME, VT) alongside EPA Lead-Safe certification, which matters on the region's pre-1978 housing stock.
4. Ask what the fasteners look like — seriously
This one question separates systems. Exposed gasketed screws through the weather surface fail early in freeze-thaw climates; concealed-fastener, interlocked panels don't. If the answer involves visible screws, ask what the maintenance schedule looks like in year twelve.
5. Insist on third-party review data, not testimonial pages
Look for reviews the contractor can't edit: Google, BBB (with rating), and independent survey platforms like GuildQuality where every response is tied to a real completed job. Cross-check volume and recency, and read the middling reviews — how a company handles a scheduling complaint tells you more than ten perfect ones.
6. Ask who actually manufactures the product
Many metal roofs are re-branded panels from commodity mills. Ask for the manufacturer, the ICC-ES evaluation report number, and the impact/fire listings — then check them. Our systems are manufactured by Interlock Roofing Ltd., documented under ICC-ES ESR-1790, UL 2218 Class 4 (Intertek 33876), and CCMC 10475-R; the documents themselves are mirrored on our proof page.
7. Expect an attic conversation, not just a roof quote
In ice-dam country, a contractor who quotes your roof without asking about attic air-sealing, insulation, and ventilation is quoting half the problem. The estimate visit should include the assembly — because the permanent ice-dam fix is the attic and the surface together.
Contractor-vetting questions, answered
How do I choose a metal roofing contractor in New England?
Apply seven checks: documented installs you can visit, a transferable lifetime warranty with a written wind rating, state licensing in your state, concealed fasteners, third-party reviews (Google, BBB, GuildQuality), a named manufacturer with ICC-ES documentation, and an estimate that assesses your attic — not just your shingles.
What questions should I ask a metal roofing company?
The four highest-signal questions: Can I see installs near me with install years? Is the warranty prorated, and does it transfer? Are the fasteners exposed or concealed? Who manufactures the panels, and what's the ICC-ES report number? Confident answers to all four are rare — and telling.
What's the difference between an installer and a certified installer?
Certification means the manufacturer trained the crews, stands behind the installation, and registers the warranty. We are the exclusive certified Interlock® installer for all six New England states — the manufacturer's engineering and our regional install record come as one package.
Should I get multiple metal roofing quotes?
Yes — and normalize them before comparing. A cheaper quote with exposed fasteners, a prorated warranty, and no ice-barrier line item isn't the same product at a lower price; it's a different (and shorter-lived) roof. Compare systems, warranties, and documentation, then price.
