Skip to content Ready for a flat roof that holds up through Missouri summers and winters? Call us for a free TPO inspection in Creve Coeur and we will walk every drain, seam, and parapet. You get a written quote and clear scope before anything is signed.
Flat and low-slope roofs in Creve Coeur take a beating from hail, ice storms, and humid Missouri summers, and the wrong membrane will start leaking within a couple of seasons. At Top Quality Exteriors, we install heat-welded TPO roofing in St. Louis that handles freeze-thaw cycles, ponding water, and ninety-degree July afternoons without splitting at the seams or cooking your monthly AC bill. Every project gets a written scope, a real schedule, and a crew that has installed TPO membranes on dozens of buildings throughout the St. Louis metro.
Our crews work with 45 mil, 60 mil, and 80 mil thermoplastic polyolefin membranes from manufacturers trusted by property managers across Maryland Heights, Chesterfield, and the Olive Boulevard corridor. Whether the building needs a fully adhered system, a mechanically fastened layout, or pairs with broader commercial roofing in Creve Coeur, we spec the right thickness, fastening pattern, parapet flashing, and seam plan up front so there are no surprises after the tear-off begins or once the membrane is rolled out across the deck.
A 60 mil white TPO membrane is the workhorse of low-slope buildings across O’Fallon, Chesterfield, and Creve Coeur, and we install it the way the manufacturer specs it, not the way that saves us a half day in labor. Heat-welded seams pull stronger than the membrane itself, so wind uplift and pooling water do not turn into call-backs in year two. The white reflective surface is EnergyStar rated, which keeps the deck twenty to fifty degrees cooler than a black EPDM membrane during a July heat wave and trims AC runtime on rooftop units. We pair the right thickness with the right attachment method: fully adhered over insulation board for retrofits, mechanically fastened with perimeter fastening on new decks, and ballasted only when the structure calls for it. Every project also gets walkway pads at rooftop access points, proper drain bowls, and parapet flashing that ties into the wall system. If you need a patch instead of a full tear-off, our roof repair in Creve Coeur crew handles flat-roof leak repairs same week.
Every flat roof project we run in Creve Coeur follows the same five steps from first call to final walkthrough. The process keeps the timeline tight, the membrane warranty intact, and your building dry through whatever the season throws at us.
We walk the roof and check seams, drains, parapets, and rooftop equipment carefully. Moisture readings tell us whether the insulation is wet. You get a written scope with photos.
We help you pick between 45 mil, 60 mil, and 80 mil TPO based on use and warranty needs. White reflective is standard for energy savings. You see samples in hand before signing it.
Old membrane and wet insulation come off and the deck gets a full inspection. Rotted decking is replaced and fasteners reset to factory spec. Drains are cleared for new flashing.
We roll out the TPO and hot-air weld every seam to factory specs. Fasteners or adhesive lock the membrane to the deck. Walkway pads, drains, and flashing all get probe-tested.
We walk the finished roof with you and pressure-test every welded seam. You get warranty paperwork and a clear maintenance schedule in writing. Call-backs go to the same crew.
We install flat roofs the same way for a single-building owner in Creve Coeur as we do for a property manager running a portfolio across Maryland Heights and Chesterfield. The crew is in-house, not subcontracted, so the foreman who quotes the job is the same person on the deck the day the membrane goes down. Heat-welded seams get probe-tested, fasteners are torqued to spec, and parapet flashing is detailed by hand on every project, not glued and forgotten.
Property managers care about uptime and warranty terms, and we treat both as non-negotiable on every job. Manufacturer warranties on TPO run fifteen to twenty years, and we register every system in your name so the paperwork is there when you need it. Tenants stay open during install whenever the layout allows, debris is contained to a single staging area, and the walkthrough leaves you with photos, drain locations, and a written maintenance plan.
Most TPO and flat roof projects in the St. Louis metro fall between seven thousand and fifteen thousand dollars, with square footage, membrane thickness, and tear-off scope driving the bulk of the number. A small commercial building in Creve Coeur with a 60 mil mechanically fastened system runs lower; a larger O’Fallon property that needs new insulation board, perimeter fastening, and full parapet flashing trends toward the higher end of that range.
We give a flat written quote after the inspection, broken out so you can see membrane cost, fasteners, insulation, drain work, and labor as separate line items. Financing is available for both single-property owners and multi-building portfolios across the metro. If insurance is involved after a hail or wind event, we work directly with your adjuster, build the Xactimate scope, and bring claim experience from storm damage roofing in Creve Coeur.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
