Your roof is one of the biggest investments you’ll make in your home. When it starts leaking, shows storm damage, or the shingles are past their prime, the contractor you hire matters as much as the materials you choose. A good roof done wrong can still cost you. This guide walks through what to check before you sign anything, so you can hire with confidence instead of guesswork.
Look for Real Local Roofing Experience
Roofs in this region take a beating. Snow load, ice dams, and sharp temperature swings between seasons all affect how a roof performs over time. As a contractor who works in Jamestown and across Chautauqua and Warren Counties year-round, we have the experience to know which materials hold up and which installation details actually matter here, not just what looks good on paper.
Ask how long the contractor you’re considering has worked in the area and whether they can point to homes nearby they’ve worked on. A contractor who’s built a reputation through referrals, rather than one who relies on ads and cold calls, usually has the track record to back it up.
Confirm Proper Licensing and Insurance
This one’s non-negotiable. Before any work starts, ask for:
- A current business license number
- Proof of general liability insurance
- A workers’ compensation certificate
This protects you in case of accidents or damage during the project. If a contractor hesitates to provide these, that’s a sign to walk away. Proper coverage protects you if something goes wrong during the job, whether that’s property damage or a jobsite injury.
Check References and Local Reviews
Recent, local references tell you more than a polished sales pitch ever will. Ask for two or three homeowners in your area you can call, and look up the contractor’s Google Business Profile for honest, unfiltered feedback. Nextdoor, local Facebook groups, and the Better Business Bureau are also worth a quick check.
And, see if a how a contractor responds to any negative reviews. A thoughtful, professional response says more than a perfect star rating.

- BBB (Better Business Bureau)
Get a Written Estimate that You Can Understand
A trustworthy contractor puts everything in writing, and the quote should match what you actually pay when the job’s done. Vague verbal estimates or numbers that change without warning mid-project are red flags. Your estimate should spell out:
A good estimate should include:
- Roof type and material specifications
- A realistic timeline for completion How cleanup and debris removal will be handled
- Payment terms
If a contractor’s estimate is careful and specific from the start, that’s usually a good sign for how the rest of the job will go.
Ask About Certifications and Warranty Coverage
Some roofing manufacturers, including GAF, CertainTeed, and Owens Corning, certify contractors who meet their training and installation standards. Working with a certified contractor can also open the door to stronger, extended warranties on materials.
Beyond the manufacturer’s warranty, ask about the contractor’s own workmanship guarantee. Find out how long it lasts, what it covers, and how they’ve handled warranty issues for past customers. A contractor who stands behind their labor, not just the shingles, is one worth trusting with the job.
Red Flags Worth Walking Away From
Most roofing contractors are professionals, but it’s worth knowing the warning signs of the ones who aren’t:
- High-pressure sales tactics or pushing you to decide on the spot
- Requests for large payments upfront, before any work begins
- No physical address or local presence you can verify
- No written contract
- Poor reviews, or no online presence at all
If something feels off during your first conversation, trust that instinct.
Questions Worth Asking Before You Sign
A short conversation before you commit can save you a lot of trouble later. Consider asking:
- How long have you worked in this area?
- Can I see photos or talk to references from recent jobs?
- Who will actually be on-site managing the project?
- What happens if weather delays the timeline?
- How do you handle cleanup and waste disposal when the job’s done?
The way a contractor answers these questions tells you a lot about how the project itself will go.
