Your Kirkwood flat roof deserves better than a patch job that fails inside a season. Call (314) 618-8888 for a free low-slope inspection and a line-itemed TPO quote. Our crew is licensed, insured, and pulls Kirkwood permits every week.
Plenty of Kirkwood homes carry a low-slope section somewhere — a dormer addition on a Meramec Highlands Foursquare, a flat porch roof off the back of a Craftsman bungalow, or a Craigwoods mid-century ranch with wide, nearly-flat eaves that shed almost no water. When those decks pond after a storm or split along the seams, TPO flat roofing is the fix that actually holds up to Missouri freeze-thaw cycles and pop-up thunderstorms. Top Quality Exteriors installs single-ply membrane built for pitches most shingle crews won’t touch.
We start with a full deck inspection, replace any rotted sheathing, and lay down a mechanically-fastened or fully-adhered TPO membrane with heat-welded seams that outlast every peel-and-stick patch job before it. Every flashing detail — parapet walls, HVAC curbs, scupper drains, pipe boots — gets a hot-air weld and a termination bar, not a bead of caulk that fails inside a season. Pair the new membrane with a roof replacement in Kirkwood on the pitched sections and your entire roof system ages together instead of on separate clocks.
Flat and low-slope roofing is its own trade — the failure modes look nothing like a Victorian gable in downtown Kirkwood. On a low-slope deck, water sits until it drains, so seams, penetrations, and terminations do all the work. We install 60-mil and 80-mil TPO in white or gray, along with EPDM rubber where a torched-down base already exists, and we spec tapered ISO insulation to build positive drainage on decks that were framed dead flat in the 1950s. Every scupper, drain, and interior gutter gets a pre-formed corner or hand-welded boot — no mastic fixes. Kirkwood’s mature tree canopy off Kirkwood Road and near Powder Valley drops enough limbs and heavy branches that puncture resistance matters as much as UV resistance, which is why we favor a fleece-back membrane on decks under big oaks. If your low-slope tie-in touches a commercial space, our commercial roofing in Kirkwood crew handles the flashing and warranty registration end-to-end.
Every flat roof we touch in Kirkwood follows the same five steps — nothing skipped, nothing improvised on the deck. Here is how a low-slope project moves from your first phone call to a heat-welded membrane you never have to think about again.
We climb your low-slope deck and check for ponding, seam failure, and rot. Photos and notes go straight into your quote. You get a clear read on what your flat roof actually needs.
Next we spec the membrane — 60-mil or 80-mil TPO, or EPDM if the deck warrants it. Tapered insulation gets designed in for positive drainage. Every detail lands on paper first.
Crews strip the old membrane down to bare sheathing in a day. Any soft or rotted decking gets swapped for new plywood before we move on. The deck must be dry and sound to weld to.
We roll out TPO, fasten or fully adhere it, and heat-weld every seam with a robotic welder. Flashings, drains, and pipe boots get hand-welded. Nothing on the roof relies on caulk.
Before we leave, every weld gets probed with a seam tester and every drain water-tested. You walk the roof with our lead and sign off. Warranty paperwork hits your inbox that week.

Low-slope work is unforgiving — one bad seam or one skipped termination bar shows up as a stain on your ceiling six months later. That is why every TPO install we run in Kirkwood gets probed with a seam tester, water-tested at every drain, and photographed for your file before we hand over the warranty paperwork. If the same storm that took your flat roof also hit your pitched sections, our storm damage roofing in Kirkwood team documents both for one insurance claim.
Most Kirkwood TPO projects land somewhere between $8 and $14 per square foot installed, depending on membrane thickness, insulation R-value, and how much rotted decking we uncover once the old roof comes off. A typical 800-square-foot dormer or porch deck runs roughly $6,500 to $11,000; a full commercial-scale low-slope over 3,000 square feet trends lower per square foot but higher overall. Every quote is line-itemed, not a lump-sum guess.
A 60-mil TPO roof installed right gives you 20 to 25 years of service, and 80-mil bumps that closer to 30 with stronger puncture resistance under limb-drop from Kirkwood’s tree canopy. We back workmanship with a firm 36-month warranty on every job, with extended options up to a lifetime warranty on selected products, and we finance through Hearth and GreenSky so a surprise leak doesn’t become a surprise bill. Storm decks often qualify for insurance coverage.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
