Choosing a roofer is a bigger decision than the price on the estimate. A good contractor protects your home for decades; a bad one can leave leaks, voided warranties, and a mess that costs more to fix than the original job. The good news is that vetting a roofer is a repeatable process. Follow these steps and you can hire with confidence instead of crossing your fingers.
The short version
Start with a shortlist of local, established roofers — not the first flyer on your door.
Verify licensing where required, plus liability and workers’ compensation insurance.
Get at least three itemized bids for the same scope and material.
Check reviews, references, and recent local work — not just a star rating.
Read the contract and warranty before you sign, and never pay in full up front.
Step 1: Build a local shortlist
Begin with roofers who work in your area and have a track record you can check. Local matters: a contractor based nearby is easier to reach for warranty work, knows your climate and code, and has a reputation to protect. Ask neighbors who recently had roofs done, search local directories, and look for companies with a physical address and a history. Be cautious of crews that appear only after a storm and cannot point to steady local work.
Step 2: Verify license and insurance
Most areas require roofing contractors to be licensed or registered, and the requirements vary by state and municipality. Confirm the license is current and covers roofing. Just as important, ask for proof of two kinds of insurance: general liability, which covers damage to your property, and workers’ compensation, which covers injuries to the crew. Without workers’ comp, you could be exposed if someone is hurt on your roof. Ask the roofer to have their insurer send a certificate directly.
Step 3: Compare itemized bids
Collect at least three written estimates for the same material and scope. A useful bid breaks out the pieces so you can compare fairly rather than staring at one big number.
Line item
Why it matters
Tear-off and disposal
Shows whether the old roof is being removed or covered over
Decking allowance
Sets a price for replacing rotted wood found underneath
Underlayment and flashing
Reveals the quality of the water barrier, not just the shingle
Ventilation
Confirms the roof will breathe and last its full life
Warranty terms
Separates a real workmanship guarantee from a vague promise

Step 4: Check reputation the right way
A star rating is a starting point, not a verdict. Read recent reviews for patterns: how the company handled problems, whether they showed up when promised, and how the cleanup went. Ask each roofer for a few local references from the past year and actually call them. If you can, drive by a recent job or ask for photos. A contractor proud of their work will happily show it.
Pro tip — watch how they handle your questions
The way a roofer answers your questions during the estimate predicts how they will treat you during the job. A pro explains the trade-offs, puts things in writing, and does not pressure you to sign today. Vagueness, defensiveness, or urgency at the sales stage tends to get worse once they have your deposit.
Step 5: Read the contract before you sign
The contract should spell out the material and shingle line, the full scope of work, the total price and payment schedule, the start and completion window, cleanup, and the warranty. Avoid paying the full amount before work begins; a modest deposit with the balance due on completion is normal, and paying in cash with no paperwork is a red flag. Make sure any verbal promises made during the sales pitch appear in writing.
Step 6: Confirm the warranty and who stands behind it
There are usually two warranties: the manufacturer’s coverage on the materials and the contractor’s workmanship warranty on the installation. Both matter, because most leaks come from installation details rather than defective shingles. Ask how long the workmanship warranty lasts, what it covers, and whether it transfers if you sell the home.

Three is a good target. It gives you a sense of the fair price range and lets you compare scope and warranty, not just the bottom line. More than three or four tends to add confusion rather than clarity.
Should I always choose the lowest bid?
No. The lowest bid sometimes skips tear-off, uses thinner underlayment, or offers a weaker warranty. Compare what each price includes. A modestly higher bid with better flashing, ventilation, and a real workmanship warranty is often the better long-term value.
Is a large upfront deposit normal?
A small deposit to schedule the job or order materials is common. Being asked for most or all of the money before work starts is a warning sign. Tie payments to milestones and hold the final payment until the work is finished and cleaned up.
Do I need a written contract for a small repair?
Yes. Even a minor repair should have the scope, price, and any warranty in writing. It protects both sides and gives you recourse if the fix does not hold.
