How to choose a roofing contractor
A four-step vetting process, the credentials that actually matter, the red flags that should stop you, and the questions to ask before you sign anything.
Hire a roofer who is licensed, insured, manufacturer-certified, and verified by real reviews — then get at least three written estimates and a written workmanship warranty before you sign. Never pay the full amount upfront.
What a roofing contractor actually does
Your roof is your home's first line of defense against sun, rain, wind, and cold. A qualified roofing contractor keeps it performing — and a good one handles far more than just nailing down shingles. Their core responsibilities include:
- Inspections. Assessing the roof's structure and materials to pinpoint problems and recommend solutions.
- Repairs. Fixing leaks, replacing damaged shingles or tiles, and addressing issues that threaten the roof's stability.
- Installations. Installing shingles, tiles, metal, or membrane roofing with techniques built to last decades.
- Maintenance. Routine checks, gutter cleaning, debris removal, and catching wear before it becomes damage.
- Safety. Following strict safety standards to protect their crew — and your property — throughout the job.
- Documentation. Providing clear contracts, warranties, and timelines so nothing is left to assumption.
The 4-step vetting process
Verify licensing & insurance
Confirm general liability and workers' compensation insurance, plus any license your state or city requires. (Roofing-license rules vary by state — some require one, others don't — so check your local requirements.)
Check certifications & reputation
Look for manufacturer certifications, an A+ BBB rating, and verified Google and Angi reviews — and read how the company handles complaints.
Get three written estimates
Compare itemized quotes line by line — materials, tear-off, decking allowance, and warranty — not just the bottom line.
Read the contract & warranty
Confirm scope, materials, timeline, payment schedule, and a written workmanship warranty before signing.
The credentials that actually matter
Manufacturer certifications
GAF Master Elite and CertainTeed Master Craftsman are held by a small share of roofers and unlock stronger system warranties. HAAG certification signals expertise in storm-damage inspection.
Licensing & insurance
Always confirm liability and workers' comp insurance. Roofing-license requirements vary by state — some mandate a license, others don't — so where no license is required, look for voluntary credentials and trade-association membership as a professionalism signal.
Roofing contractor vs. roofing company
You'll see both terms used. The biggest difference is the scale of operations: contractors usually work a defined local area and often bring in subcontractors, while companies operate larger — sometimes nationwide — with in-house crews and project managers. Neither is automatically better; it depends on your project.
Independent contractor
- Often higher, more custom craftsmanship
- You usually deal with one person throughout
- Well-suited to unusual or one-off projects
Roofing company
- Larger crews that work faster
- Often longer track record & vetted employees
- May offer extended warranties and competitive pricing
If you hire a contractor who uses subcontractors, verify their credentials too. If you prefer a single accountable party with in-house staff, a company may suit you better.
Red flags to walk away from
Walk away if you see…
- Door-to-door pressure or "we're already in your neighborhood" right after a storm.
- Large upfront deposits or a demand to pay in full before work starts.
- No written contract, no physical address, or no proof of insurance.
- A bid dramatically lower than every other quote.
- Pressure to sign today, or offers to "waive your deductible" (often insurance fraud).
The hiring process, step by step
Once you've shortlisted candidates, hiring a roofer comes down to three stages:
Initial consultation
Discuss your goals and timeline, and — just as importantly — gauge their communication style. Come with a list of questions about experience and any challenges your roof presents.
Obtain & compare quotes
Get itemized quotes broken down by materials, labor, and extras. Compare value, not just price — the lowest bid rarely delivers the best long-term result.
Sign the contract & begin
Confirm the contract matches the estimate — scope, timeline, payment schedule, permits, and cleanup — then sign. A reputable roofer keeps you updated through completion and a final inspection.
Questions to ask before you sign
- Are you licensed and insured — can I see current certificates?
- What manufacturer certifications do you hold?
- Is the estimate itemized, and what's the allowance for decking repairs?
- What's the workmanship warranty, and is it transferable?
- What's the payment schedule, and who handles permits and cleanup?
