Premium architectural shingles. Most homes done in a single day. Backed by a 10-year workmanship warranty and the manufacturers homeowners trust most. Free, no-pressure estimates within 24 hours.
If you're reading this, your roof is either past its prime, was just hammered by a hailstorm, or you've been quoted somewhere between $8,000 and $25,000 by three different roofers and you have no idea who's telling the truth. We get it.
This page is the no-fluff guide to roof replacement in St. Louis — the costs, the materials, the process, and the warning signs that separate honest contractors from the ones who'll disappear two years after they cash your check. By the end you'll know exactly what your roof should cost, what should be in your contract, and what questions to ask before you sign.
And if you'd rather just talk to a human, our number is at the top of the page. Call us — we'll give you straight answers.
St. Louis roofing prices range broadly depending on roof size, pitch (steepness), complexity (chimneys, valleys, dormers), and the quality of materials you choose. Here's a realistic range based on actual projects we've completed in 2024–2025:
Note: "Sq" is roofer shorthand for "squares" — a unit equal to 100 square feet. A 25-square roof equals 2,500 square feet.
A legitimate roof replacement in St. Louis should include all of the following — and if a competing quote leaves any of these out, you're being set up for surprise charges later:
St. Louis weather is brutal on roofs. We get hot, humid summers in the upper 90s, freeze-thaw cycles every winter, severe thunderstorms, hail, and the occasional tornado warning. Your roofing materials need to handle all of that for 25–30 years.
Architectural shingles — also called "dimensional" or "laminated" shingles — are the modern standard. They're heavier, thicker, and last longer than the old 3-tab shingles your grandparents had. The two brands we install most are:
For most St. Louis homes, either of these is the right choice. The price difference is minimal and the performance is comparable. We'll show you samples and let you decide based on color and look.
Underlayment is the layer between your decking and your shingles. It's your second line of defense if water ever gets past the shingles — and on a steep slope or in heavy rain, it absolutely happens.
The old standard was 30# felt paper. We don't use it anymore. We install synthetic underlayment exclusively — typically RhinoRoof U20, ABC Pro Guard 20, or GAF FeltBuster depending on the project. Synthetic is:
Ice & Water Shield is a self-adhering membrane that goes in valleys and at eaves. It's required by St. Louis code at any roof eave to protect against ice damming in winter — when snow melts on your warm roof, runs to the cold eave, and refreezes, backing water under your shingles. We install at least 6 feet of Ice & Water Shield up from every eave, plus full coverage in every valley.
Flashing is the metal that seals your roof to anything that pokes through it — chimneys, vent pipes, walls, skylights. Bad flashing is the #1 cause of roof leaks, period. We install:
Your attic needs to breathe. Without proper ventilation, summer heat builds up in your attic, cooks your shingles from below (cutting their lifespan in half), and makes your AC work overtime. In winter, trapped moisture causes mold and rot.
We install continuous ridge venting on every roof we replace — combined with intake at the soffits — to provide balanced attic ventilation that keeps your roof and your home performing properly.
Here's exactly what happens from your first phone call to the magnetic nail-sweep we do before driving away. No mystery, no marketing fluff.
Call us or fill out the form. We come out within 24–48 hours, climb up, take photos, measure carefully, and discuss your options. No pressure.
You get a written, itemized estimate within 1 business day. Every line explained. Multiple shingle/color options if you want them.
Once you sign, we order materials and put you on the schedule. Most homes start within 1–3 weeks (faster for storm damage).
We deliver materials, drop a dumpster (or use a debris trailer), and confirm timing. Move your cars out of the driveway.
Crew arrives at 7AM, tarps your landscaping, and tears off the old roof. We inspect the decking and replace bad sheets.
Synthetic underlayment, Ice & Water Shield in valleys/eaves, new flashings, then shingles from the bottom up. Ridge cap last.
Magnetic nail-sweep across yard, driveway, gutters, and flowerbeds. Dumpster hauled away. Photos taken for our records.
You receive your written 10-year workmanship warranty plus the manufacturer warranty registration. Done.
Roofing is logistics. We typically run 4–6 person crews — a tear-off lead, two installers, a ground person managing materials, and a foreman overseeing quality. With proper coordination, a 25-square roof goes up in 6–8 hours. Larger or more complex jobs split into 2 days, but we never leave a roof exposed overnight if there's a chance of rain (we tarp first).
Here are the most common signs that it's replacement time, not repair time. If you check 3 or more of these, schedule a free inspection — we'll give you an honest assessment, not a sales pitch.
If you're seeing several of these, the next step is a free inspection. We'll get up on your roof (or use a drone), take photos of every issue, and give you an honest assessment of what you're dealing with.
Sometimes the answer is "you've got 5 more good years" and we send you on your way. Sometimes it's "yeah, this needs to come off." Either way, you'll have facts to work with — not a high-pressure pitch.
📞 Schedule Your Free InspectionNot every leaky roof needs to be torn off. We turn down replacement jobs every week because the customer just needs a $400 repair. Here's how we (and any honest roofer) decide:
Here's a real example: last spring a customer in Webster Groves called us about a leak. Three other roofers had quoted full replacements between $11,000 and $14,000. We climbed up, found the leak was around a single chimney where the counter flashing had pulled away from the brick, and fixed it for $375. The roof had 8+ good years left.
That kind of honesty is why people refer us. It's also why we sleep at night.
Materials warranties (the 30-year, 50-year, "lifetime" warranties from CertainTeed and GAF) are great, but they only cover material defects — not how it was installed. If the leak is from a flashing your roofer didn't install correctly, the manufacturer doesn't cover it. Your contractor does. Or doesn't, if they've gone out of business.
Our 10-year workmanship warranty covers everything related to how we installed your roof:
The warranty is in writing, registered with our office, and tied to your address. It's transferable to a new homeowner if you sell. And it's backed by a company that's been here since 2024 and isn't going anywhere — we're the same family that runs AIO Pro Chimney, also serving St. Louis since 2024.
Most St. Louis homes are completed in a single day. Larger or more complex roofs (multiple stories, lots of valleys, decking replacement) may take 2 days. We never leave a roof exposed overnight if there's any chance of rain.
No. Most customers prefer to be home when we start so we can answer any final questions, but you can leave once we're underway. We'll call before we arrive and again when we finish.
We tarp your bushes, AC units, and flowerbeds before we start. After tear-off, we run a magnetic nail-sweep across the entire perimeter (3–4 passes). You shouldn't find a single nail in your yard.
Pets stay inside please. The noise of nail guns and tear-off can stress dogs significantly. If you have outdoor cats, keep them in for the day.
Yes. Roof replacement requires a permit in St. Louis County and most municipalities. We pull the permit, the building inspector checks our work mid-job, and the permit is closed at completion. You don't have to do anything.
Generally no — and often the opposite. A new roof (especially with Class 4 impact-resistant shingles) often qualifies you for a discount of 5–25% on your homeowner's premium. Ask your agent.
Lighter colors (driftwood, weathered wood, gray) reflect heat in summer — they can drop attic temps by 5–10°F. Darker colors (pewter, charcoal, onyx) hide algae streaks better but absorb more heat. Most St. Louis homeowners pick a mid-gray or weathered wood. We'll show you samples.
Yes — we partner with several financing companies that offer 0% APR for qualified buyers, plus longer-term plans (60, 84, or 120 months) at competitive rates. Most homeowners can be pre-approved in minutes.
We watch the radar obsessively. If rain is forecast, we either reschedule or work in shorter windows and tarp the roof at the end of each work session. Your interior will never be exposed to weather.
Yes — we remove old, unused dishes at no charge. Active dishes need to be temporarily disconnected and re-installed (usually by your dish provider). We can coordinate timing.
