Updated September 27, 2026, by Lane House Roofing & Exteriors
Direct Answer
Lane House Roofing & Exteriors is a roofing company based in Mehlville at 3814 Lemay Ferry Rd, and an Owens Corning Preferred Contractor [1] [2]. In Mehlville, St. Louis County requires no permit for a like-for-like shingle roof at 4:12 or steeper, but a low slope, heavy deck repair, or new material needs one [3].
TL;DR
- Lane House’s office at 3814 Lemay Ferry Rd sits inside Mehlville, and the company has replaced roofs since 2003 [1] [4].
- Mehlville is unincorporated, so St. Louis County sets the reroof rules. A like-for-like asphalt shingle roof at 4:12 or steeper needs no permit [3].
- A permit is required for a slope under 4:12, more than 25% new sheathing, a change of material, or board sheathing that must become panels [3].
- Even without a permit, tear-off to the deck, drip edge, step flashing, and vent checks still apply [3].
- County code doesn’t require an ice barrier, but Owens Corning Preferred Protection needs two of three extras, including that option [3] [5].
- Most jobs take one to three days on the roof, and Missouri bars roofers from paying your deductible [6] [7].
One liner: Ask any roofer to check your slope, deck, and material before you sign, so you know whether the county needs a permit.

Your Roofing Company in Mehlville, MO, Right on Lemay Ferry Road
In short: Lane House is a full-replacement roofer with its office on Lemay Ferry Road, inside Mehlville.
Lane House Roofing & Exteriors is the roofing company Mehlville, MO homeowners can find right on Lemay Ferry Road. Our office sits at 3814 Lemay Ferry Rd, inside Mehlville [1], so for most of our neighbors we’re a short drive down the road.
We focus on full roof replacement [9]. We tear off the old roof, check the decking underneath, and install a complete Owens Corning roofing system. We’re an Owens Corning Preferred Contractor [2] and hold an A+ rating with the Better Business Bureau [10]. We’re licensed and insured, with workers’ compensation and general liability coverage protecting you and our crews [4]. We also replace siding, windows, and gutters, so one crew can handle the whole outside of your house. We don’t take on small patch repairs.
Lane House has been in business since 2003. Our founder, Kerry House, brings 40 years in the roofing trade, and he built the company to be a roofer Mehlville neighbors can stop by and see in person. Mehlville roofing comes with its own local rules, and the first question most homeowners ask us is about permits. The next section answers it.
Do You Need a Permit for a Roof Replacement in Mehlville?
In short: Most like-for-like shingle jobs at 4:12 or steeper need no county permit, but low slopes, heavy deck repair, and new materials do.
Usually not. Mehlville is unincorporated, so St. Louis County sets the building rules here. The county doesn’t require a permit to replace asphalt shingles with new asphalt shingles on a roof sloped 4:12 or steeper [3]. A low slope, a big deck repair, or a new roofing material changes that.
Slope is written as rise over run, so a 4:12 roof climbs 4 inches for every 12 inches across. Most pitched house roofs are steeper than that, but porch roofs and low additions often aren’t.
| Your roof job | County permit needed? | What it means for you |
|---|---|---|
| New asphalt shingles replacing asphalt shingles, slope 4:12 or steeper | No | Work can start once materials arrive |
| Any roof section sloped less than 4:12 | Yes | Drawings and a county review come first |
| More than 25% of the roof sheathing replaced | Yes | Heavy deck rot turns a no-permit job into a permit job |
| A different roof material, such as wood shingles to asphalt or shingles to metal | Yes | Required at any slope |
| Old board sheathing with gaps too wide for code, covered or replaced with panels | Yes | The deck upgrade is reviewed under the permit |
Skipping the permit doesn’t mean skipping the rules. The county says work done without a permit still has to meet the reroofing code [3]. That means stripping the old roof down to the deck unless there’s only one sound layer, drip edge at the eaves and rakes, step flashing where the roof meets a wall, and an attic vent check.
Code sets the minimum, and the warranty asks for more. The county doesn’t require an ice barrier on a shingle reroof [3]. Owens Corning’s Preferred Protection warranty requires two of three extras: ice and water barrier, starter shingles, or ventilation [5]. A roof can pass code and still fall short of that warranty. We install to the warranty standard, and our roof replacement page explains what it covers [9].
Before you sign, we check your slope, your decking, and your material choice, and we file with the county when your job needs a permit.
The Roof Replacement Mehlville Homes Need
In short: Owner-occupied homes and South County weather make a done-once replacement worth planning before a leak.
Most Mehlville homes are owned by the people who live in them. About 66% are owner occupied, and the median home value is $218,400 [8]. When you plan to stay put, the roof replacement Mehlville homes need is a big project, and it’s worth doing once.
South County weather is hard on shingles. Winter freeze and thaw works water into small gaps, summer heat bakes the attic, and spring storms bring hail and high wind. We cover hail in its own section below.
| What you see | What it usually means | Next step |
|---|---|---|
| Curling or missing shingles | Shingles are near the end of their life, or wind has lifted them | Book an inspection |
| Heavy granules in the gutters | The shingle surface is wearing away | Book an inspection |
| Water stains on a ceiling | Water is getting past the roof | Call soon, before the deck rots |
| Soft or sagging spots | The decking underneath may be damaged | Call soon and stay off the roof |
| A roof more than 15 to 20 years old | It’s near the 15 to 25 year design life of most roofs [4] | Plan ahead instead of waiting for a leak |
A small ceiling stain in March is often a flashing problem, and by October it can mean soft decking and a bigger bill. We’ll inspect your roof and give you a straight read, and if it still has good years left, we’ll tell you that too.
Our Mehlville Roof Replacement Process
In short: Seven steps take you from a free inspection to a registered Owens Corning warranty, with one to three days on the roof.
Most Mehlville roof replacements take one to three days on the roof. From your first call to the final walkthrough, plan on two to six weeks, since the inspection, material order, and any permit come first [6].
- Free inspection. We measure the roof, take photos, and check the decking from the attic when we can.
- Written scope. You get a clear written estimate and pick your Owens Corning shingle line and color.
- County check. We confirm your slope, deck condition, and material, and file with St. Louis County only when a permit trigger applies [3].
- Delivery and prep. Materials and a dumpster arrive, and we tarp your landscaping before any work starts.
- Tear-off and deck check. We strip the roof to the bare deck and replace any soft or rotted sheets.
- Install. Drip edge, ice and water barrier, synthetic underlayment, starter strip, shingles, step flashing, and ventilation matched to your attic.
- Cleanup and walkthrough. We sweep the yard with a nail magnet, walk the job with you, and register your Owens Corning warranty.
Why tear off every time? County code allows one new layer over a single sound layer [3], but an overlay hides the deck. A tear-off is the only way to find rot before it’s sealed under a new roof.
You won’t get a bill until the job is done, apart from a partial payment on special order material. Financing is available, and we’ll walk you through the options at your free estimate [4].
Hail and Storm Damage in South County
In short: Book a free hail inspection after storms; Missouri law bars roofers from negotiating claims or paying deductibles.
Hail damage often can’t be seen from the ground. Book an inspection after a big storm, even if nothing is leaking [4]. Our free hail damage roof inspection checks every slope and counts impacts in test squares [11]. It also covers vents, flashing, gutters, and decking, and ends with photos and a written report.
If you file a claim, Missouri law limits what any roofer can do [7].
| Missouri rule | What it means for you |
|---|---|
| A contractor can’t represent you or negotiate your claim | We document the damage; you and your insurer settle the claim |
| A contractor can’t promise to pay or rebate your deductible | An offer to cover your deductible breaks state law |
| You can cancel within five business days of written notice that the claim isn’t covered | A denied claim doesn’t lock you into the contract |
After a hail storm, door knockers often show up in South County offering to cover your deductible. Treat that as a red flag. We’ll inspect and document what we find. If the damage calls for a full replacement, we’ll build the job around that scope.
See Our Roof Replacement Work
In short: Our project gallery and customer reviews show the work before you call.
Our Completed Projects gallery shows real roofs we’ve replaced across the St. Louis area [12]. As you look, check the ridge lines, the straight shingle rows, and the flashing around chimneys and walls, since that’s where good work shows.
Reviews tell the rest. One repeat customer wrote that we kept them informed from start to finish and that the crew worked hard to get the new roof on. You can also pair a new roof with gutters or siding, so the whole outside of the house matches when we’re done [4].

Do I need a permit to replace my roof in Mehlville?
Usually not. St. Louis County doesn’t require a permit to replace asphalt shingles with asphalt shingles on a roof sloped 4:12 or steeper. You do need one for a lower slope, for replacing more than 25% of the sheathing, or for switching to a different roofing material [3].
Do you install metal roofing in Mehlville?
Yes. We install metal roofing as well as Owens Corning asphalt shingles [4]. Going from shingles to metal counts as a change of material, so St. Louis County requires a permit for that job at any slope [3]. We handle the permit filing for you.
How long does a roof replacement take in Mehlville?
Most roofs take one to three days of work on the roof itself. From your first call to the final walkthrough, plan on two to six weeks, since the inspection, material order, and any permit come first [6].
Can a roofer pay my insurance deductible in Missouri?
No. Missouri law bars contractors from promising to pay or rebate any part of your deductible. It also bars them from negotiating your insurance claim for you [7]. A roofer can inspect and document the damage, and you settle the claim with your insurer.
Do you do roof repairs?
No. We focus on full roof replacement, plus siding, windows, and gutters, so we don’t take small patch repairs [4]. If we inspect your roof and it still has good years left, we’ll tell you that instead of selling you a new one.
Do you offer financing for a new roof?
Yes. Financing can cover the full cost of your roof replacement, and we’ll go over the options at your free estimate. You won’t get a bill until the work is finished, apart from a partial payment on special order material [4].
Can I choose my shingle color and style?
Yes. Owens Corning shingles come in a wide range of colors and styles, and we’ll help you match your new roof to your siding, trim, and gutters. You’ll see samples and pick your line and color when you sign [4].
