How to Choose a Roofing Contractor: A Homeowner's Checklist

Hiring the wrong roofing contractor costs Salt Lake City homeowners more than a bad material choice ever could — a voided warranty, unpermitted work that complicates a future home sale, or a crew that's gone before the first storm tests their installation. With dozens of companies bidding on roofs across the Wasatch Front every storm season, knowing how to separate a legitimate local contractor from a risky one is one of the most valuable things a homeowner can learn before signing anything. Here's a practical, step-by-step checklist.

Start With Licensing and Insurance

This is the non-negotiable first step, and it takes less than five minutes. Before any contractor sets foot on your roof, confirm they're who they say they are.

• License Verification: Every roofing contractor working in Utah should hold an active license — check for General Building B100, Roofing S230, or Sheet Metal S280 as applicable — using the state's free DOPL license lookup tool. A legitimate contractor won't hesitate when you ask for their license number.
• Proper Insurance: Ask for a Certificate of Insurance showing both general liability and workers' compensation coverage. Without it, you could be financially responsible if a worker is injured on your property.
• A Permanent Local Address: Not a P.O. box, and not just a phone number from an out-of-state area code. A company with a real local presence has a reason to stand behind its work years down the road.

Check Reviews and Local Reputation

Online reviews are a starting point, but they're easy to manipulate. Cross-reference what you find with the Better Business Bureau, which tracks complaint history and how a company responded to past disputes — a more reliable signal than star ratings alone. Ask any contractor for references from recent local jobs, and actually call them. A company with nothing to hide will welcome the conversation.

Ask About Manufacturer Certifications

Certification level matters more than most homeowners realize, because it directly affects what warranty coverage you qualify for. Manufacturers including GAF and CertainTeed offer enhanced, non-prorated warranty tiers — but only when the installer holds a specific certification level with that manufacturer. Ask directly whether a contractor is certified, and with which manufacturers, before assuming your roof will qualify for the best available coverage. Our guide on understanding roof warranties breaks down why this distinction matters once something actually goes wrong.

Get a Written, Itemized Estimate

A trustworthy estimate names the specific product line and manufacturer, breaks out material and labor, and spells out what's included — tear-off, disposal, decking inspection, underlayment type, flashing details, and cleanup. A vague one-line number is a red flag regardless of how competitive it looks. Our roof replacement cost guide explains what actually drives pricing along the Wasatch Front, which makes it easier to tell whether a quote is realistic or missing something.

Red Flags to Walk Away From

• Storm-Chasing Crews: After every major Wasatch Front hailstorm, out-of-state crews go door-to-door offering fast, cheap repairs. Many are gone before the warranty period ends, leaving homeowners with no recourse if something fails. See our broader list of roofing mistakes Utah homeowners make for more on this pattern.
• Pressure to Sign Immediately: A legitimate contractor gives you time to compare bids. High-pressure, same-visit-only pricing is a sales tactic, not a genuine limited-time deal.
• Offers to Waive Your Insurance Deductible: If a contractor offers to cover or "eat" your deductible to win the job, treat it as a serious red flag rather than a perk — it's the kind of arrangement that can leave the homeowner exposed if a claim is ever reviewed.
• A Bid Dramatically Lower Than Every Other Quote: It almost always means a shortcut somewhere — thinner underlayment, undersized flashing, or a crew that skips proper ventilation entirely.

Confirm the Workmanship Warranty in Writing

A manufacturer's warranty only covers material defects — it says nothing about installation quality. That's the job of the contractor's own workmanship warranty, and its length varies enormously across the industry. Get the terms in writing before work begins, not as a verbal promise afterward. Our full breakdown of manufacturer vs. workmanship coverage explains exactly what each one protects and where homeowners most often get caught off guard.

When the Roof Needs a Second Opinion

If you're not sure whether what you're looking at is a legitimate concern or a sales tactic, an independent professional roof inspection is the easiest way to get a straight answer before you commit to any bid. A real inspector documents conditions with photos and gives you something concrete to compare against whatever a contractor is telling you.
