Ponding water, blistering, or membrane tears? Simmons Roofing repairs flat and low-slope roofs across Southeast Missouri — stopping leaks at the source.
Flat and low-slope roofs face challenges a steep roof never does — water sits on them and drains slowly, which finds every weakness. Over time that leads to ponding water, blistering, cracking, membrane tears, and failed seams. Simmons Roofing repairs flat roofs of every type across Southeast Missouri — built-up (BUR), modified bitumen, and single-ply membranes.
Every repair starts with a thorough inspection to find the true source. On a flat roof, leaks typically develop at the seams, flashing, drains, and low spots where water collects — so we trace the problem to its origin instead of just sealing the surface.
As a family-owned company that's licensed, insured, and bonded, we back our repairs, and every one begins with a free, no-obligation estimate.
These are the issues we most often repair on flat and low-slope roofs.
Drainage and low-spot issues addressed so water moves off the roof.
Blisters and surface cracks in the membrane repaired before they open up.
Tears and punctures patched and sealed watertight.
Failed seams and flashing cleaned and resealed at the source.
On a sloped roof, gravity does a lot of the work — water runs off before it can cause trouble. A flat roof has no such luxury. Water pools, sits, and works on any weak point until it finds a way in, which is why flat roofs demand prompt, knowledgeable repair.
A small membrane tear, a lifted seam, or a clogged drain can turn into an interior leak surprisingly fast. Catching it early — and fixing it with the right materials and technique for your specific system — is what keeps a minor issue from becoming a soaked ceiling.
Whether it's BUR, modified bitumen, or single-ply, we know how each system fails and how to repair it right.
Every flat roof repair is done to stop the leak and keep water moving off the roof.

Because water sits on them instead of running off. Flat and low-slope roofs are prone to ponding water, and over time that standing water works on seams, flashing, drains, and any small membrane damage until it gets through. Most flat-roof leaks trace back to those points.
Often, yes. Ponding is usually a drainage or low-spot issue, and we can address it by improving drainage and correcting the problem areas so water moves off the roof instead of pooling. We'll assess the cause during your inspection.
We repair built-up roofing (BUR), modified bitumen, and single-ply membranes including EPDM, on both residential and commercial buildings. Each system fails and repairs differently, and we work with all of them.
It depends on the roof's condition and age. Isolated tears, seams, or drainage issues are usually a straightforward repair. If the membrane is widely failing or near the end of its life, we'll show you what we found and lay out repair-versus-replacement honestly.
Yes. Many flat roofs are on commercial buildings, and we handle commercial and residential flat-roof repairs at every scale — from a home addition to a large commercial roof.
