Ready to fix the flat roof on your Frontenac home before the next round of Missouri thunderstorms? We will schedule a free, no-pressure roof walk and written report within a few business days. You will know what the TPO project costs upfront.
Flat and low-slope sections on Frontenac estate homes take a beating from standing water after Missouri thunderstorms, and a failed seam can soak the decking long before you ever notice a stain on the ceiling. Top Quality Exteriors installs heat-welded 60 mil TPO roofing in St. Louis that handles the local climate, drains properly, and shrugs off our brutal humid summers without bubbling, shrinking, or pulling away from the parapets. We build this system around what actually fails first here, not what a generic national spec sheet recommends for a milder climate.
Every install pairs an EnergyStar-rated white reflective membrane with tapered ISO insulation, fully welded seams, and reinforced flashing at every penetration, drain, and curb on the roof field. If your project also needs steep-slope work tied in along an addition or porte-cochere, our roof replacement in Frontenac crew coordinates both systems so the transition between the flat and pitched sections stays fully watertight from day one through year twenty, with a clean, finished detail at the change of plane.
Frontenac sits in a microclimate that punishes flat roofs harder than most homeowners realize. Severe Missouri thunderstorms dump two inches of rain in an hour, then a humid 95 degree afternoon bakes whatever water sits behind a parapet wall or around a sluggish drain. That cycle is what tears apart older modified bitumen and aging EPDM rubber, especially at the seams. A properly installed 60 mil TPO membrane with heat-welded laps removes the failure point: the seam is now stronger than the surrounding sheet itself. We also slope every recover or new install with tapered ISO so water actually moves toward the drain instead of pooling in the field. Combine that with a white reflective surface, EnergyStar performance, and 15 to 20 years of expected life, and you have a system designed for the way our weather actually behaves. For storm-related issues on either membrane or shingled sections, our storm damage roofing in Frontenac team handles documentation, tarping, and full restoration.
Every flat roof we replace in Frontenac runs through the same five-step playbook. It keeps the schedule predictable, the price honest, and your home protected from the first day we walk the roof to the final punch-list inspection.
We climb the roof, photograph every drain, seam, and penetration, and pull cores where needed. You get a written report with photos that same day. No guessing involved on our part.
We engineer the assembly around your deck condition, slope, and drainage. Then we hand you a fixed quote with materials, tear-off, disposal, and warranty itemized line by line.
Crews strip the failed membrane, inspect every inch of wood decking, and replace rotted sheathing on the spot. We tarp every night so a sudden Missouri storm never reaches inside.
We mechanically attach or fully adhere 60 mil TPO, heat-weld every seam, and detail flashings at every curb, drain, and parapet. Each weld is probed by hand the same afternoon.
We flood-test the drains, photograph the finished assembly, and walk every single detail with you before we leave. You get manufacturer paperwork and our workmanship warranty.
TPO looks straightforward on a product spec sheet, but the installation is where most flat roofs fail. A cold weld, a poorly detailed parapet, an undersized roof drain, or a deck left a quarter inch too low and the membrane fights standing water for the next two decades. Our crews are factory-trained on TPO welding, carry hand-probe tools on the roof at all times, and refuse to leave a single seam unverified before tear-down at the end of the work day.
We have been installing low-slope and modified bitumen replacements across the St. Louis metro for years now, and Frontenac is squarely in our home territory. You deal with the same project manager from the first walk through the final flood test inspection, not a rotating cast. For pitched sections on the same property, our roof repair in Frontenac team handles tie-ins, flashing repairs, and ridge work without subbing the job out to a stranger.
Most TPO and flat roof projects we run in Frontenac land between 7,000 and 15,000 dollars depending on square footage, deck condition, the number of penetrations, and how much tapered ISO the slope correction calls for. A simple recover over sound substrate sits at the lower end. A full tear-off with rotted decking replacement, new drains, and steep tapered insulation puts you closer to the top of that range, sometimes higher on bigger estate homes.
That cost still beats the alternative of nursing a failing 20-year-old EPDM rubber roof through three more leak repairs. The math also shifts once you factor in the EnergyStar-rated white membrane shaving cooling loads through hot, humid St. Louis summers. We give every Frontenac homeowner a fixed written quote with no change-order traps. Need a fresh look on more than one elevation? Our roof inspection in Frontenac team writes detailed reports.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
