How do you choose the right roofing contractor? Ask about licensing and insurance, experience with your specific roof type, references from past work, and how the estimate is broken down — a contractor who answers all of that clearly and directly is worth trusting with the job.

Ask About Licensing and Insurance
Any contractor working on your roof should be able to provide proof of a current license and both liability and workers’ compensation insurance. This protects you if something goes wrong during the job — without it, property owners can end up liable for accidents on their own property.
Don’t hesitate to ask for documentation directly rather than taking a verbal assurance at face value. A legitimate contractor will have no issue producing it, and most will offer it as a matter of course before work begins.
It’s worth verifying this information independently rather than taking a contractor’s word for it. A quick call to the license board or a request for a certificate of insurance sent directly from the insurer gives you a way to confirm coverage is active, not just that it exists on paper.
Ask About Experience With Your Roof Type
Not every roofing contractor works with every material. If you’re considering SPF, ask specifically about their experience with spray foam application — it’s a different skill set from shingle or sheet-membrane roofing, and experience matters for a clean, even application.
Ask how long they’ve worked with the material and roughly how many similar projects they’ve completed. A contractor who’s installed dozens of SPF roofs will generally have a smoother process and fewer surprises than one just getting started with the material.
It’s also fair to ask how a contractor’s crew stays trained as materials and installation methods change. Roofing systems evolve, and a company that invests in ongoing training for its installers is more likely to catch details a less experienced crew might miss.
Ask for References and Past Work
A contractor with a solid track record should be able to point you to completed projects, ideally ones similar in scope to yours. Photos of finished work and, where possible, contact with past clients can tell you more than a sales pitch can.
If possible, ask to see a project that’s a few years old rather than freshly completed — that tells you more about how the work has actually held up over time.
When you follow up with references, ask specific questions rather than just whether they were happy overall — how the crew communicated during the project, whether the timeline held, and how any issues after the work was done got handled. Those details tell you more than a general recommendation does.
Ask How the Estimate Is Broken Down
A clear estimate should separate material costs, labor, and any additional work like repairs or drainage corrections. Vague, all-in numbers make it harder to know what you’re actually paying for and to compare quotes fairly between contractors.
It’s reasonable to ask for a written, itemized estimate rather than a verbal number, and to get the same breakdown from more than one contractor before deciding.
A line-item estimate that breaks down materials, labor and any additional work is easier to compare across contractors than a single lump-sum number. If one estimate is noticeably lower than the others, it’s worth asking what’s different — sometimes it’s a lower price on the same scope, and sometimes it means something was left out.
Beyond the specific questions, pay attention to how a contractor communicates throughout the estimating process. A contractor who answers questions clearly, follows up when they say they will, and puts the details of the project in writing is generally easier to work with once the job is underway than one who’s vague or hard to reach before you’ve even signed anything.
Payment terms deserve the same scrutiny as the rest of the estimate. A reasonable deposit to secure materials and scheduling is normal, but a contractor asking for full payment up front, in cash only, is worth a second look. Spreading payments across the project, with a final payment due once the work is complete and you’re satisfied, protects you if something doesn’t go as planned.
Online reviews are useful, but they tell only part of the story. A contractor with a handful of overwhelmingly positive reviews and no negative ones at all is worth a closer look, since it’s unusual for any company to have a perfect track record. A mix of mostly positive reviews, with thoughtful responses to the occasional complaint, often says more about how a company actually handles problems.
Ask About Warranty Coverage
Ask what’s covered under warranty, for how long, and whether it covers both materials and workmanship. A contractor confident in their work will have clear answers here rather than vague assurances.
Some warranties cover materials only, leaving labor for a repair uncovered — it’s worth understanding that distinction clearly before signing anything.
Frequently Asked Questions
How many quotes should I get before choosing a contractor? Getting at least two or three quotes is generally a good practice, as long as each one is broken down clearly enough to compare fairly.
Should I be concerned if a quote is much lower than the others? It’s worth asking why. A significantly lower quote sometimes means lower-quality materials, less experience, or corners being cut somewhere in the process.
Is it normal for a contractor to ask for a deposit? Yes, a reasonable deposit is standard practice, but be cautious of any contractor asking for full payment upfront before work begins.
Red Flags to Watch For
Be cautious of contractors who pressure you to sign immediately, can’t produce documentation, or give estimates significantly lower than everyone else without a clear explanation why. Learn more about our team and approach before you decide who to work with.
