If your commercial building has active leaks, aging membrane, or storm damage that needs professional eyes, reach out to schedule a rooftop survey. We’ll walk the roof, document the condition, and send a straight scope the same week.
Property owners along Cherokee Street, Gravois Avenue, and Grand Boulevard know the reality of commercial roofing in St. Louis — flat and low-slope membranes tucked behind century-old brick parapets, aging coping stones, and mortar joints that leak into interior brick long before the field membrane itself ever fails. Top Quality Exteriors works these buildings week after week, from Soulard rowhouse storefronts and Dutchtown two-flats to mid-rise mixed-use along the Central Corridor and warehouses near Downtown and the riverfront.
Our commercial crews build every scope around what the building actually needs — TPO or PVC single-ply for a large open field, EPDM rubber over irregular decks, or modified bitumen where parapet transitions and scupper details matter most. Whether you manage a retail storefront, multi-family flat, or industrial box near the riverfront, we quote from a real rooftop inspection, coordinate with tenants, and pair every install with a roof replacement in St. Louis plan that respects historic-district review when it applies.
The commercial building stock inside the city runs on flat and low-slope roofing — mod-bit, EPDM, TPO, and PVC single-ply behind brick parapet walls, not the pitched asphalt-shingle systems the suburbs live on. We match the membrane to the deck and the traffic pattern: mechanically attached TPO on wide-open industrial fields near The Hill and Carondelet, fully adhered PVC where grease exhaust or restaurant vents scar the surface, and torch-down modified bitumen on tight Soulard rowhouses where parapet transitions and coping tie-ins drive the leak map. Every scope begins with a wall-junction inspection, because most St. Louis leaks trace to the roof-to-parapet flashing or failed coping mortar — not the field membrane. When your building sits inside a local historic district, we route the permit through the City Building Division and coordinate Preservation Board sign-off before tear-off begins, and we back the finished job with a TPO and flat roofing in St. Louis warranty program.
We keep commercial roofing jobs predictable from the first walk-through to the final punch list. Every project moves through the same five stages so property managers, tenants, and lenders always know exactly what happens next on the roof.
We walk the entire membrane, parapet run, and drain field before writing a scope. Core cuts confirm the deck and insulation layers. Every finding gets photographed for your file.
We build the spec around traffic, drainage, and code, then price it line by line. You see product data sheets, warranty tiers, and clean terms up front. Zero boilerplate here.
We pull the City Building Division permit and route Preservation Board review when needed. Staging, dumpsters, and tenant notice are locked in. Nothing rolls onto site unannounced.
Crews tear off failed membrane, replace wet insulation, and re-flash every parapet. Fasteners, seams, and terminations are inspected as we go. Daily quality checks run on the roof.
We walk the finished system with you before demobilization. Warranty docs, closeout photos, and manufacturer registrations land in your hands. Maintenance visits get scheduled.
Every commercial roof in the city rides on one decision — repair, restore, or replace — and the wrong call costs tenants, revenue, and interior finishes. Our team has spent 7+ years working the flat and low-slope stock that defines the St. Louis commercial corridor, from Cherokee storefronts to south-side warehouses and multi-family buildings around Tower Grove. As an Owens Corning Preferred Contractor licensed in Missouri and Illinois, we bring the paperwork.
We know the local playbook because we work it every week — the City Building Division permit process, Preservation Board review inside historic districts like Soulard, and party-wall coordination on attached rowhouses where a shared parapet decides who owns the leak. BBB Accredited crews carry liability and workers comp on every site, and we back commercial work with a 36-month workmanship warranty, with fast triage for storm damage roofing in St. Louis.
Commercial pricing in St. Louis lands where the deck condition, membrane system, and access complexity meet. A 10,000 square-foot mechanically attached TPO reroof on an accessible warehouse near I-70 prices very differently from a torch-down mod-bit tie-in on a Soulard rowhouse with alley-only access and shared parapet walls. We price by real square footage, tear-off depth, insulation R-value, drain and scupper work, and coping repair — never by rough per-square guesses.
Long-term value hinges on the warranty stack. Our commercial installs pair a firm 36-month workmanship warranty with manufacturer coverage from Owens Corning and other partners — 20-year and NDL options available on qualifying single-ply systems. Hearth and GreenSky financing keep replacement projects moving without draining reserves, and every quote separates capital work from maintenance so property managers can plan cleanly through the next hail season.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
