After years spent flying drone inspections over roofs across Williamson County, we've learned that the most expensive roofing mistake most homeowners make happens before a single shingle is touched. It happens the moment they choose the wrong contractor. Brentwood's mix of large, steep estate roofs and Middle Tennessee's punishing storm season means the stakes here are higher than in most markets. Here is exactly how to vet a roofer the way a professional inspector would.
Start With Tennessee Licensing, Then Verify It Yourself
In Tennessee, any roofing project with a total cost of $25,000 or more requires a state-issued contractor's license carrying a roofing classification. Because a full replacement on a typical two-story Brentwood home runs well past that threshold, this rule applies to nearly every job in our area. A business card and a truck logo are not proof of anything.
Ask for the license number and check it yourself using the Tennessee Board for Licensing Contractors' free "Verify a License" tool online. Confirm the name matches the company on your contract, that the roofing classification is active, and that the monetary limit covers your project's size. On the larger estate roofs in neighborhoods like Governors Club, Annandale, and Taramore, an underqualified monetary limit is a genuine red flag.
Insurance: The Certificate That Protects Your Home
Two coverages matter, and you should never take them on faith. Ask for a Certificate of Insurance that lists both:
- General liability — protects your property if a crew damages your home, a skylight, or a neighbor's vehicle during the job.
- Workers' compensation — in Tennessee's construction industry, businesses are generally required to carry workers' comp with even one employee. Without it, a worker injured on your steep roof could become your financial problem.
For real protection, call the insurance agent named on the certificate and confirm the policy is active on the day work begins. Uninsured or underinsured crews are common among the pop-up outfits that surface after every hail event.
Spot the Storm-Chasers Before They Knock
When a spring hailstorm rolls across Franklin Road or straight-line winds tear through the tree canopy near Crockett Park, the door-knockers arrive within days. Some are legitimate. Many are not. After the March 2020 tornado outbreak and nearly every severe-weather season since, we've inspected roofs that out-of-state crews "repaired" and then abandoned before the first warranty call.
Watch for these warning signs:
- Out-of-state license plates, phone numbers, or no verifiable local address.
- High-pressure demands to sign a contract today before the "deal" disappears.
- An offer to waive or absorb your insurance deductible — this is insurance fraud under Tennessee law and puts you at risk.
- Requests for a large cash deposit up front, or asking you to sign over your insurance check.
- No Tennessee license number printed on the written contract.
A reputable Brentwood roofer will gladly wait while you verify credentials and gather a second opinion. Storm-chasers will not.
Warranties: Manufacturer vs. Workmanship
This is where homeowners get burned most often, because the two warranties cover completely different things.
Manufacturer warranty
This covers defects in the roofing material itself — shingles from makers like GAF, Owens Corning, or CertainTeed. Standard architectural shingles carry a "lifetime" limited warranty, but the fine print is prorated and drops sharply after the first 10 to 15 years. Enhanced warranties, such as GAF's Golden Pledge or Owens Corning's Platinum, offer far stronger, longer, non-prorated coverage, but only manufacturer-certified contractors are permitted to register them. Ask whether your roofer holds that certification.
Workmanship warranty
This is the contractor's own guarantee on installation, and it matters enormously. The vast majority of leaks we document from the air come from installation errors — improper flashing around chimneys and valleys, exposed nails, and poor attic ventilation — not defective shingles. A manufacturer will not cover a leak caused by bad workmanship. Workmanship warranties in our market typically range from 2 to 10 years. Ask how long it lasts, whether it transfers if you sell your home, and, most importantly, whether the company is likely to still be in business to honor it.
Questions to Ask Before You Sign
- What is your Tennessee license number, and may I verify it?
- Can I see a current certificate of insurance for liability and workers' comp?
- Will my crew be your employees or subcontractors?
- Are you a manufacturer-certified installer, and which warranty will you register?
- Will you pull the required City of Brentwood building permit?
- Can you share recent references from homeowners in Brentwood, Franklin, or Nolensville?
Get everything in a written, itemized estimate. For budgeting, a straightforward architectural-shingle replacement on a Brentwood home generally runs $14,000 to $30,000, while large, steep estate roofs can exceed $60,000. Wide swings between bids usually mean the scope is not the same, so compare underlayment, flashing, and ventilation line by line rather than just the bottom number.
