Missouri Does Not License Roofers, So Vetting Is On You
Missouri does not license roofers at the state level, which surprises most homeowners. A statewide registration with the Department of Commerce and Insurance exists, and it requires proof of liability and workers compensation coverage. Registration is not the same as a skills license, so the real burden of vetting falls on you.
Some cities add their own rules on top. St. Louis requires a construction business license, and municipalities across St. Charles County set their own permit and contractor standards. A roofer working legally in Lake Saint Louis should know exactly which permits your job needs and pull them without you having to ask first.
Local Roofer vs Storm Chaser: The Difference That Matters
After a hail event, out-of-town crews flood the St. Charles and west St. Louis market. They rent a local number, knock doors for a couple of weeks, and leave once the insurance claims dry up. A local company is still here in three years when a flashing detail leaks and you need it fixed.
The test is simple. Ask where the office is and drive past it. Ask how long the owners have worked this metro. A contractor rooted in the community stakes its reputation on every job because the next customer is a neighbor. A storm chaser stakes nothing because it will be three states away.
Verify Licensing and Insurance Before Anyone Climbs Up
Insurance is where corners get cut and homeowners get burned. Ask for a certificate of insurance showing general liability and workers compensation. Then call the agent listed on it and confirm the policy is active and current. That phone call takes five minutes and protects you from a lawsuit if a worker falls.
Workers compensation matters more than people think. If an uninsured roofer is injured on your roof, you can be held liable for the medical costs. Liability coverage protects your property if the crew damages your siding or a neighbor's car. No certificate, no crew on your roof, and that rule has no exceptions.
What Manufacturer Certifications Actually Mean
Shingle makers like CertainTeed and GAF vet the contractors they certify. To earn top credentials a company proves years in business, trained installers, financial stability, and clean insurance. CertainTeed's Master Shingle Applicator and SELECT ShingleMaster tiers and GAF accreditation are earned, not bought, and only a small share of roofers ever hold them.
This matters for one concrete reason. A certified installer can register a manufacturer-backed warranty covering materials and workmanship for decades, and that coverage stays in force with the manufacturer even if the contractor closes shop. An uncertified roofer cannot offer it. LSL's Tony carries CertainTeed Master Craftsman standing and GAF accreditation.
Get a Detailed Written Estimate, Not a One-Line Quote
Get everything in writing before a single shingle moves. A real estimate names the shingle brand and line, the underlayment, ice and water shield, flashing, ventilation, tear-off and disposal, the number of layers removed, and the total price. Vague one-line quotes hide the substitutions that turn a fair bid into an expensive one.
Collect at least three itemized estimates and compare them line by line. That comparison shows you the true market price and exposes the outlier. When two bids match on scope and one comes in far cheaper, the cheap one is almost always leaving something out. Ask what the low bidder removed, then decide.
Workmanship Warranty vs Manufacturer Warranty
Two different warranties protect a new roof, and homeowners confuse them constantly. The manufacturer warranty covers defects in the shingles themselves. The workmanship warranty covers the installation, meaning the labor and the details where most leaks actually start. You want both, in writing, with clear terms and a stated duration for each.
A workmanship warranty is only as good as the company standing behind it. A five-year workmanship warranty from a local business that answers its phone beats a longer promise from a crew that vanishes after storm season. Ask how warranty claims are handled and exactly who to call when something goes wrong.
Red Flags: Big Deposits, Door-Knocking, and Deductible Deals
A few behaviors reliably signal trouble. A large upfront deposit is the clearest one. Established roofers order materials on credit and bill on completion or in staged draws. Anyone demanding full payment or a heavy deposit to hold your spot on the schedule is a real risk. Never hand over the full amount before work begins.
Watch the sales approach too. High pressure to sign today, an offer to waive or eat your insurance deductible, and door-knocking right after a storm are all warning signs. Waiving a deductible is insurance fraud that can leave you exposed. Real contractors give you time and never ask you to commit fraud.
The Exact Questions to Ask Any Roofer
Print this list and ask every roofer the exact same questions. Their answers, and how readily they give them, tell you more than any brochure or yard sign. A confident local contractor welcomes the scrutiny. A storm chaser gets vague, deflects, or grows impatient, and that reaction is your answer.
