How Much Does a Roof Cost in St. Louis?
A typical St. Louis asphalt shingle roof replacement runs $7,000–$16,000 on a standard 1,800-square-foot home, or $350–$700 per square (100 sq ft). Architectural shingles run $450–$650 per square installed; premium impact-resistant shingles — the smart buy in hail country — run $600–$900 per square. Metal roofs run $15,000–$30,000 for the same home, and repairs are $300–$1,500 for most leaks and shingle damage.
Roofing labor in the St. Louis metro averages $150–$250 per square, and most installs take 1–3 days. A recent 2,300-square-foot home in Webster Groves paid $13,400 for a full architectural shingle replacement with new ridge venting and ice-and-water shield in the valleys.

Does a St. Louis Roofer Need a License?
Missouri has no statewide roofing license, but the City of St. Louis requires contractors doing work in the city to register with the City's License Collector and carry workers' compensation and liability insurance. St. Louis County and St. Charles County similarly require contractor registration. Registration isn't a competence test, so do your own vetting: check the BBB rating, ask for proof of insurance (a certificate naming you as additional insured), and confirm manufacturer certifications like GAF Master Elite or Owens Corning Preferred.
Insurance is the non-negotiable. Missouri doesn't require roofers to carry workers' comp, and a roofer without it means YOU can be liable if a worker is injured on your property. Ask for the certificate before signing anything. Also verify the warranty: most St. Louis roofers offer a 5-year workmanship warranty, with 25–50 year manufacturer warranties on the shingles themselves.
St. Louis Hail Alley: Storm Damage and Your Claim
St. Louis sits in the heart of Hail Alley, and the region's severe spring and summer storms pound roofs with hail, wind, and tornadoes. The April 2024 hailstorm across the Midwest caused billions in insured losses, and St. Louis roofs took direct hits. Hail damage isn't always obvious from the ground — bruising on asphalt shingles (loss of granules) can weaken a roof for years without leaking.
If a storm hits, have a licensed roofer inspect within a few weeks. Missouri homeowners insurance covers hail and wind damage, but you must file within your policy's time limits, and insurance companies often lowball the first estimate — an independent roofer's inspection report is your evidence. Most St. Louis roofing companies offer free storm inspections and will walk you through the claims process, including meeting the adjuster on your roof. A roofer who pressures you to sign over your claim (an "assignment of benefits") is a red flag — read anything that transfers your insurance rights.
St. Louis Weather: Heat, Humidity, and Roof Lifespan
St. Louis summers hit 100°F+ with brutal humidity, and the heat bakes asphalt shingles — literally. A roof on the sun-blasted west side of a home can age 30% faster than one on the north side. The typical St. Louis asphalt roof lasts 18–25 years, but the metro's intense UV, freeze-thaw cycles, and hail routinely cut that to 15–18 years on older homes.
Venting is the big St. Louis issue: poor attic ventilation traps 130°F+ heat in summer and causes ice dams in winter, both of which void shingle warranties. When you replace a roof here, insist on proper ridge and soffit venting and consider light-colored or impact-resistant shingles. Metal roofing is growing in the metro precisely because it handles hail and heat better, lasting 40–70 years with only $200–$400/year in maintenance.
Frequently Asked Questions
How do I know if my St. Louis roof has hail damage?
Look for missing granules in gutters and downspouts, bruised or dented shingles, cracked flashing, and dents on vents, gutters, and AC units. A licensed roofer's free inspection can document damage that's invisible from the ground — crucial for an insurance claim.
How long does a roof replacement take in St. Louis?
Most residential replacements take 1–3 days, weather permitting. Storm season (April–July) can stretch timelines to 2–4 weeks because every roofer in the metro is booked solid after major hail events.
Does homeowners insurance cover roof replacement in Missouri?
Yes, for sudden storm damage like hail or wind. Missouri policies pay actual cash value (ACV) unless you have replacement cost coverage — most homeowners should carry the latter, since ACV can leave you paying thousands out of pocket on an older roof.
Should I repair or replace my roof?
Repair if damage covers less than 30% of the roof and the roof is under 15 years old. Replace if the roof is over 18–20 years, has multiple leaks, or shows widespread hail bruising — repeated repairs on an aging roof cost more than one replacement.
What's the best roofing material for St. Louis weather?
Impact-resistant architectural shingles are the best value for most homes — they survive hail and qualify for insurance discounts. Metal roofs cost 2–3x more but last 40–70 years and are the best hail and heat performers in the metro.
