Systems We Install

Flat & Low-Slope Roofing For St. Louis Buildings

Warehouses, offices, retail, churches, and apartment buildings. Specified to the building's real conditions and installed without shutting your operation down.

TPO single-ply

Heat-welded seams and a highly reflective white surface that reduces cooling load on large, exposed roof areas. A strong default for warehouse and big-box retail.

EPDM rubber membrane

A proven synthetic rubber system with excellent resistance to temperature swings, UV, and standing water — well suited to Missouri's range from ice to heat.

Modified bitumen

Multi-ply, reinforced, and tough underfoot. The right call for roofs with regular maintenance traffic and dense mechanical penetrations.

Metal systems

Standing seam and architectural metal for long service life and low maintenance on both commercial and institutional buildings.

Liquid roof coatings

Restore an aging but structurally sound membrane and extend its service life — often a fraction of the capital cost of a full tear-off, and it stays out of your landfill.

Commercial repair & maintenance

Seam repair, flashing at curbs and penetrations, drain and scupper correction, and scheduled inspection programs that catch problems before they become claims.

Common Questions

What Homeowners Ask Us

Which flat roofing system is right for my building?

It depends on the building, not on what we prefer to install. TPO's reflective white surface cuts cooling load on wide-open warehouse and retail roofs. EPDM is a durable, proven rubber membrane that handles ponding and temperature swings well. Modified bitumen suits roofs with heavy foot traffic and complicated penetrations. Liquid-applied coatings can add years to an aging membrane without a tear-off at all. We spec to your drainage, HVAC layout, and traffic pattern.

Will the work shut down my business or disturb tenants?

No. Our commercial crews sequence around your operating hours, stage materials to keep entrances and loading docks clear, and work section by section so the building stays occupied and open. For apartment and multi-tenant properties we coordinate notices so your residents know what is happening and when.

Can you repair a flat roof instead of replacing it?

Frequently, yes. Most commercial leaks trace to seams, flashing at penetrations, drains, or curbs rather than a wholesale membrane failure. We locate the actual entry point, repair it, and give you a straight assessment of the remaining service life so you can budget instead of guess.

Do you handle apartment buildings and multi-unit properties?

Yes. Property managers and apartment owners are a core part of our commercial work, including multi-building portfolios where scheduling and resident communication matter as much as the roofing itself.

Is emergency service available for commercial roofs?

Yes. The same 24/7 line at (314) 429-6000 dispatches for commercial buildings. Ponding water on a membrane roof adds serious structural load and finds every weak seam, so after-hours calls on flat roofs get treated as urgent.
