Built-up roofing, modified bitumen, and single-ply membranes — Simmons Roofing installs durable flat roof systems for homes and businesses across Southeast Missouri.
Flat and low-slope roofs need a completely different approach than a steep shingle roof. Simmons Roofing installs the full range of flat roofing systems — built-up roofing (BUR), modified bitumen, and single-ply membranes — for both residential and commercial buildings across Southeast Missouri.
On a flat roof, drainage and waterproofing are everything. Water drains slowly, so the system has to be sealed tight and built to handle it. We install for proper drainage, watertight seams, and long-term performance, backed by solid warranties.
As a family-owned, licensed, insured, and bonded company, we handle flat roofs of every size — from a home addition to a commercial building — and we provide a free, no-obligation written estimate before we start.
We install every major flat roofing system — here's what we work with.
Multiple layers of material for tough, time-tested, long-lasting protection.
A durable asphalt-based membrane engineered specifically for flat roofs.
Membranes like EPDM for clean, watertight, low-maintenance coverage.
Flat roofs of every size and scale, on homes and businesses alike.
A flat roof isn't truly flat — it's designed with a slight slope to move water toward drains. When that drainage and waterproofing aren't done right, water pools and eventually finds its way in. Ponding water is the number-one enemy of a flat roof.
That's why flat roofing is its own craft. The seams, the flashing, the drainage, and the membrane all have to work together to keep water moving off the roof and out of the building.
We install flat roofs to do exactly that — choosing the right system for your building and installing it to last.
Every flat roof we install is built to stay watertight for the long term.

It depends on the system, but a professionally installed flat roof typically lasts 15 to 30 years or more. Proper drainage, quality materials, and correct installation are the biggest factors in how long it holds up.
Because water drains slowly and can pond on a flat surface. That standing water is what leads to leaks over time, so flat roofs depend on proper slope, drainage, and watertight seams — details that require flat-roofing experience to get right.
