Flat roofs fail in different places than shingle roofs. Water sits longer, seams and flashings carry more of the load, and a small opening can let water travel far before it shows up inside. A good repair starts with finding where water actually enters.
Common flat roof problems we see in St. Louis
Freeze-thaw cycles, summer heat and heavy spring rain all stress low-slope membranes. Most leaks trace back to a handful of details rather than the open field of the roof.
- Open or lifted seams on TPO and EPDM membranes
- Ponding water near clogged or poorly placed drains
- Cracked flashing at walls, curbs and rooftop units
- Blisters and splits in modified bitumen
- Punctures from foot traffic or debris
Repair, restore or replace?
A localized seam or flashing repair can extend the life of a roof that is otherwise sound. Wet insulation over large areas, repeated leaks in several places or an aging membrane can make replacement the more practical choice. Your assessment should explain which areas are affected and why a repair is or is not recommended.

Common questions
Why does my flat roof leak only during heavy rain?
Heavy rain can overwhelm drains and raise ponding water above seams or flashing details that stay dry in lighter storms. An inspection checks drainage as well as the membrane.
Can a flat roof be repaired in winter?
Some temporary and permanent repairs can be made in cold weather, depending on the membrane and conditions. Call to discuss what is possible for your roof.
What type of flat roof do I have?
Most low-slope roofs in the area are TPO, EPDM rubber or modified bitumen. We identify the system during the assessment so repair materials match.
