Your Olivette flat roof has been through a lot since the May 2025 storms, and waiting lets water damage the decking underneath. Call (314) 618-8888 for a free roof survey with photos and a written report. We pull the Olivette permit for you.
If your Olivette commercial building or mid-century ranch with a low-slope addition is losing seam integrity, ponding water after every storm, or showing dark streaks around the drains, you need a flat roofing specialist who knows the 63132 area inside and out. At Top Quality Exteriors, we install heat-welded TPO membranes engineered for hot, humid Mid County summers and the wind events that hammer properties along the I-170 corridor each spring. Every job gets scoped around what your building actually has on the deck right now.
TPO roofing has become the workhorse of the Olivette flat-roof market for good reason. The white reflective membrane cuts cooling loads straight through July and August, and properly heat-welded seams stand up to the hail and straight-line winds that hammered Mid County during the May 2025 EF3 event. For owners weighing a full system replacement versus a targeted patch after wind uplift, our roof repair in Olivette team will scope either path honestly, without the upsell pressure storm chasers bring after a major event.
Olivette sits in an unusual spot for flat roofing demand. Mid-century ranches built between the 1940s and 1960s make up roughly 58% of the housing stock, and many of those homes have low-slope additions, sunroom roofs, or carport extensions that never worked well under shingles. At the same time, the commercial and mixed-use properties along the I-170 corridor and Olive Boulevard sit almost entirely on flat decks. The May 16, 2025 EF3 tornado that pushed 155 mph winds across the region tore membranes off roofs, and the 3–5 hail events the metro averages each year keep seam integrity at the top of every property manager’s list. When we install a 60-mil heat-welded TPO membrane with proper perimeter fastening and parapet flashing, we engineer for what actually hits Olivette: wind uplift, hail impact, ponding around drains, and UV exposure. Need a different system specified? Our commercial roofing in Olivette crew can talk EPDM, modified bitumen, or fully adhered TPO based on your deck.
Every Olivette flat-roof project follows the same five-step process so you know exactly what happens on your building, when it happens, and what gets inspected. From the first walk on the roof to the final permit sign-off, here is how we work.
We walk your Olivette roof, check seam welds, drain conditions, and parapet flashing, then photograph every issue. You get a written report the same day. No deposit, no pressure.
We pick 45-mil, 60-mil, or 80-mil TPO based on your traffic and exposure. Mechanical, fully adhered, or ballasted attachment gets matched to your deck. Pricing is fixed up front.
We submit the reroof permit to the Olivette Department of Planning and Community Development, including decking specs. The city reviews and inspects. You never chase paperwork.
The crew tears off old material, inspects the deck, and lays insulation. We hot-weld every seam, install perimeter fastening, and flash drains and parapets to manufacturer spec.
We pass the Olivette city inspection, then walk your roof with you to confirm seam welds, walkway pads, and the clean drains. Your workmanship warranty paperwork is handed over.
Olivette runs a tighter permit process than most cities in the area. Any reroof, including membrane removal and decking work, requires a permit through the Department of Planning and Community Development before crews can touch the roof. We pull every permit ourselves, submit three sets of plans when needed, and meet the inspector on site so the city signs off the first time. That rigor is the simplest way to tell a real local contractor from a storm chaser.
Top Quality Exteriors was founded in 2022, and owner Mario Granados brings over 7 years of industry experience to every Olivette project. We are BBB Accredited with an A+ rating, licensed in Missouri, and carry general liability and workers compensation insurance. Whether the building is a Tower Hill office, a mixed-use property near Olive Boulevard, or a 1950s Oak Estates ranch with a flat sunroom addition, our install standards stay the same on every job.
A typical TPO flat roof project in Olivette runs $7,000 to $15,000, depending on square footage, insulation thickness, attachment method, and how much existing decking has to come off. A small ranch sunroom addition off a 1950s Oak Estates home falls toward the low end. A larger commercial deck along the I-170 corridor with full insulation, fully adhered membrane, and parapet flashing sits at the upper end. Fixed bids in writing before work starts.
What drives cost on an Olivette flat roof: membrane thickness (45-mil, 60-mil, or 80-mil), attachment style (mechanical, fully adhered, or ballasted), insulation R-value, deck repair square footage, drain replacements, and Olivette permit fees. Most TPO systems deliver a 15 to 20 year service life when installed to manufacturer spec. Financing through Hearth and GreenSky is available for qualified owners.
