Own a downtown Overland storefront on Woodson Road or a small warehouse near Lackland? We would be glad to walk your flat roof and lay out a plain-English scope. Call (314) 618-8888 and we will schedule a free inspection this week.
The flat commercial roof over your Woodson Road storefront or the low-slope addition on an Overland ranch is losing water every time a hard Missouri rain rolls through, and last summer’s cheap patch stopped holding weeks back. Ponding puddles, split seams, and blistered membranes are what we find on aging built-up and mod-bit covers across this north county city. At Top Quality Exteriors, we install TPO and flat roofing in Overland that sheds water, reflects UV, and gives small commercial buildings a dry cover for two full decades.
Our crews specialize in single-ply membrane work on the mid-century storefronts along Woodson Rd and Lackland Rd, plus the low-slope garage and porch add-ons behind post-war capes off Page Ave. We tear down to the deck, spot-treat rot at parapet walls and drain edges, lay fresh polyiso with tapered fall, and heat-weld TPO seams so water has nowhere to sit for long. When you need commercial roofing in Overland that outlasts the last cover you paid for, we scope the whole assembly first and hand you a written proposal by manufacturer name.
Downtown Overland was built in the decade after WWII, and the Woodson Road and Lackland Road commercial strip is a run of small low-slope buildings originally covered in coal-tar built-up or, later, mod-bit. Sixty years on, most of those covers are on their second or third membrane, parapet flashing has cracked, and the drains no longer sit at the low point of the field. We rebuild these assemblies from the deck up: pull the old plies, sister any rotted 1x board sheathing at the eaves, set new tapered polyiso to feed the drains, cap it with a cover board, and mechanically fasten a 60-mil TPO membrane over the whole layout. Cool-white TPO reflects the summer sun off buildings near St. Ann and Woodson Terrace, cuts HVAC load through Missouri’s humid July heat, and gives owners a clean 20-year membrane warranty. When hail rolls through north county from the southwest, as it did on May 16, 2025, we walk the post-storm inspection at no charge. For a steep-slope neighbor building, we bundle roof replacement in Overland under one contract.
Flat roofing is not shingles laid on a pitch, so we handle it differently from the first phone call. Here is how a TPO or EPDM job runs from the moment you call us out to a Woodson Road storefront to the day we hand you the warranty paperwork.
We meet you on the deck and map every drain, seam, curb, and vent. A water test finds hidden leaks when the field ponds during rain. Then we photograph the cover for your file.
Back at the office, we draw the assembly and price it line by line. The written scope names every material and warranty term in plain English. No verbal handshakes on flat work.
Our crew pulls the failed membrane, cuts out wet insulation, and inspects the deck for rot. Bad 1x board sheathing at the eaves gets sistered right there. Then we sweep the field.
We lay tapered polyiso for positive drainage and cover it with a fire-rated board. TPO rolls out, seams get heat-welded, and probe-tested on the spot. Flashing terms to walls.
Before we leave, we flood-test low points, walk every drain, and hand you photos of the cover. Warranty paperwork lands in a folder. Then we schedule a follow-up in twelve months.
Top Quality Exteriors was founded in 2022, and our owner and lead crews carry over 7 years of industry experience, since single-ply membrane is where cheap subs cut corners on flat work. We are a BBB Accredited Business with an A+ rating, licensed in Missouri and Illinois, and covered by general liability and workers’ compensation on every low-slope job we run. As an Owens Corning Preferred Contractor, our manufacturer discipline carries into flat roofing too.
We know the north county commercial strip. Our crews have walked roofs above Woodson Road hair salons, small offices off Lackland, and the low-slope garage and porch add-ons behind post-war capes near Wild Acres Park. That means we know what fails first in this town, which brands hold up in humid Missouri summers, and how to phase a re-roof so a store owner in downtown Overland can keep the doors open through the whole install. Local, licensed, accountable.
Flat roofing pricing swings on three variables: square footage, membrane type, and how much wet insulation and deck rot we uncover after tear-off. A straight TPO overlay on a sound Woodson Road commercial deck lands at the lower end of the metro range, while a full tear-off with new tapered polyiso and rebuilt parapet flashing runs higher. We price the whole assembly up front, name every material by manufacturer, and never bill for a change you have not signed off on.
Overland owners hate paying twice, so we spec systems that last: 60-mil TPO over cover board, mechanically fastened for wind, with a 20-year membrane warranty and our 36-Month workmanship warranty layered on top. Extended coverage up to Lifetime is available on select products. Financing through Hearth and GreenSky is on the table, and we route hail claims from events like May 16, 2025 through storm damage roofing in Overland.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
