How to choose a roofing contractor: red flags and questions to ask

Hiring a roofing contractor is one of the bigger home decisions most people make, and the difference between a smooth job and a headache usually shows up before any work starts, in how the contractor handles the estimate, the contract, and their answers to direct questions. Our ranked list of Hartford Metro roofing contractors is a useful starting point, but the questions below apply no matter who you are considering.

Verify the basics first

Connecticut requires roofing contractors doing residential work to hold a Home Improvement Contractor (HIC) registration. Ask for the registration number and confirm it is current. Also ask for proof of general liability insurance and workers’ compensation coverage, and get the actual certificate rather than taking someone’s word for it. If a roofer is unlicensed or uninsured and a worker is hurt on your property, you could end up liable.

Manufacturer certifications, like GAF Master Elite or CertainTeed’s SELECT ShingleMaster designation, are a second, optional layer of vetting. These are not required to do good work, but contractors who maintain them have gone through additional training, and hiring one typically qualifies you for a stronger material warranty than a standard installer can offer. Neither certification is a guarantee of a good experience on its own, but it does confirm the contractor has met a manufacturer’s independent standard rather than just their own word for it.

What a solid estimate looks like

A trustworthy estimate is itemized: tear-off and disposal, decking repair, ideally priced per sheet or per hour rather than a vague allowance, underlayment and flashing, the finish material, labor, and any code-required upgrades like ventilation or ice-and-water shield. If a quote is one lump number with no breakdown, ask for a rewrite before you compare it against anything else.

Get everything in writing: start date, estimated completion window, payment schedule, material brand and product line, and both a manufacturer materials warranty and a separate workmanship warranty covering labor. Verbal promises about “we’ll take care of it” are not a substitute for contract language.

Red flags worth walking away from

Reviews and complaints across the Hartford Metro market point to a consistent handful of warning signs. Watch for:

• A contractor who pressures you to sign the same day, especially after an unsolicited door knock following a storm
• A request for a large deposit, or full payment, before any work has started
• No fixed address or a phone number that only accepts texts, not calls
• Vague answers when you ask about licensing, insurance, or the specific crew who will do the work
• A quote that is dramatically lower than every other bid with no clear explanation

None of these guarantee a bad outcome on their own, but two or more together are a strong reason to keep looking. Trust your own read of the interaction too. A contractor who answers direct questions plainly, without deflecting or rushing you, is telling you something about how they will handle the actual job as well.

Questions worth asking every contractor

Question	Why it matters
Can I see your HIC registration and insurance certificate?	Confirms legal standing and protects you from liability
Who will actually be on my roof: your crew or a subcontractor?	Subcontracted crews vary in quality and accountability
What is your plan if you find rotted decking?	Reveals whether pricing surprises are handled fairly
What does the workmanship warranty cover, and for how long?	Separates a contractor who stands behind labor from one who doesn’t
Can you give me two recent local references?	A confident contractor will not hesitate here

Trust the pattern, not just one review

No contractor has a perfect record, and a single negative review is not disqualifying. What matters more is the pattern: fair pricing and responsive communication show up again and again in the strongest local reviews, while dishonesty, aggressive upselling, or vanishing after a deposit show up as recurring complaints for the contractors worth avoiding. Reading several recent reviews, not just the star average, tells you more than the number alone.
