10 Questions to Ask Before Hiring a Roofing Contractor

Your roof is not the place to cut corners. And yet, thousands of homeowners and commercial property owners hand over significant money to contractors who disappear after the first check or worse, leave behind a roof that fails before the warranty even kicks in. The roofing industry, unfortunately, has more than its fair share of fly-by-night operators. They show up after a storm, offer rock-bottom prices, do mediocre work, and move on before you realize something went wrong. The good news? You can protect yourself. And it doesn’t take much just the right questions, asked at the right time. Before you sign anything or hand over a single dollar, here are the 10 questions every homeowner and commercial property owner should ask their roofing contractor.

1. Are You Licensed and Insured?

This is non-negotiable. Full stop A legitimate roofing contractor will carry both a valid contractor’s license and two types of insurance general liability insurance and workers compensation coverage. General liability protects your property if something gets damaged during the job. Workers comp protects you from being held liable if a worker gets injured on your roof. Ask for proof not just a verbal “yes.” Any credible contractor will have no problem handing over their certificates. If they hesitate, that’s your cue to walk away.

2. Do You Have Local References I Can Contact?

Reviews on Google are helpful. But nothing beats being able to call an actual person in your area who had the same work done. Ask for at least 2–3 references from recent local projects and actually call them. Ask how the crew behaved, whether the timeline was met, and if they’d hire the contractor again. A roofing company with a strong local reputation will have references ready. One that’s been operating in your area for years will have plenty of homeowners and property managers willing to vouch for their work.

3. What’s Your Experience With This Type of Roof?

Not all roofs are created equal. A contractor who’s exceptional at asphalt shingles may have limited experience with flat commercial roofs, metal roofing, or TPO membranes. Make sure the contractor you’re hiring has hands-on experience with your specific roof type. If you’re managing a commercial property, this question becomes even more critical commercial roofing systems are a different animal entirely compared to residential projects. Ask directly: “How many projects like mine have you completed in the last 12 months?”

4. Will You Pull the Necessary Permits?

Permits aren’t just bureaucratic red tape. They exist to ensure the work meets local building codes and they protect you if you ever sell the property. Some contractors suggest skipping permits to “save time and money.” That’s a red flag. Unpermitted roofing work can result in fines, failed home inspections, and voided insurance claims. A reputable contractor handles the permit process as a standard part of the job. If someone tells you permits aren’t necessary for your project, get a second opinion.

5. What Does Your Warranty Cover?

There are two types of warranties to ask about: the manufacturer’s warranty on the materials and the workmanship warranty from the contractor. Material warranties can range from 20 years to a lifetime depending on the product. But workmanship warranties which cover the actual installation vary widely. Some contractors offer 1 year. Others offer 10. The best ones stand behind their work with longer coverage periods. Understand exactly what’s covered, what voids the warranty, and how you file a claim if something goes wrong. Get it in writing.

6. Who Will Actually Be Doing the Work?

This one catches a lot of people off guard. Many roofing companies don’t use their own crews. They subcontract the work to third-party laborers sometimes people the contractor barely knows. That creates accountability gaps. If something goes wrong, the finger-pointing starts and you’re stuck in the middle. Ask directly: “Is your crew in-house, or do you subcontract?” Neither answer is automatically a dealbreaker, but you deserve to know who will be on your property and who’s responsible if the work doesn’t meet standards.

7. What’s the Project Timeline?

Roofing projects have a way of dragging on when there’s no clear schedule in place. Get a realistic timeline upfront including the start date, estimated completion date, and how weather delays are handled. For commercial clients especially, downtime matters. You need to know when work will happen, how it affects building operations, and what the contingency plan looks like. A contractor who can’t give you a clear timeline is either overbooked or disorganized. Either way, that’s worth knowing before you commit.

8. How Do You Handle Unexpected Damage or Costs?

Once a crew starts tearing off old roofing, surprises happen. Rotted decking, hidden moisture damage, structural issues they’re not always visible until the work begins. Ask your contractor how they handle unexpected discoveries. Do they stop and get your approval before proceeding? Or do they make decisions on the fly and add costs to your final bill without warning? The answer tells you a lot about how they operate. The best contractors communicate clearly, document additional findings with photos, and get written approval before any out-of-scope work begins.

9. What’s Your Payment Schedule?

Be very cautious of any contractor who demands full payment upfront. That’s a major red flag and unfortunately, it’s a common tactic used by scammers who disappear after the deposit clears. A standard, trustworthy payment schedule usually looks something like this: a modest deposit to secure the project, a progress payment at a project milestone, and the final balance upon completion and your approval. Everything should be clearly outlined in a written contract. If a contractor pushes back on putting payment terms in writing, that’s reason enough to find someone else.

10. Can You Provide a Detailed Written Estimate?

A verbal quote means nothing if something goes wrong. Before any work starts, you should have a written estimate that breaks down:

• Materials (brand, type, quantity)
• Labor costs
• Permit fees
• Project timeline
• Payment schedule
• Warranty details

This document is your protection. It’s also a useful tool to compare bids from multiple contractors because the cheapest quote rarely tells the whole story. A lower price often means cheaper materials, rushed labor, or corners being cut somewhere.

Always compare apples to apples.

One More Thing: Trust Your Gut

You can ask all the right questions and still pick up on something that feels off. Maybe the contractor seems evasive. Maybe they’re pushing hard for a quick decision. Maybe they showed up uninvited right after a storm. Those instincts exist for a reason. Don’t ignore them. The right roofing contractor will never pressure you, will answer every question confidently, and will put everything in writing without being asked twice. They want you to feel informed because they’re confident in their work.
