Flat roofing is what separates experienced contractors from general roofers. The materials are different, the installation methods are different, and the failure points are different. Doe Run Roofing & Maintenance has been installing flat roofs in Doe Run for 17 years. We know what works and what doesn't in MO's climate.
Our Flat Roofing Process
Membrane Assessment
Before recommending repair, coating, or replacement, we inspect the entire flat roof system. Membrane condition, insulation integrity, and drainage patterns all factor into our recommendation.
Detailed Proposal
Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.
Expert Flat Roof Crew
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Completion & Warranty
Your flat roof gets a completion package: installation documentation, warranty certificates, drainage verification, and maintenance recommendations. We stand behind every flat roof we install in Doe Run.

Why Choose Doe Run Roofing & Maintenance for Flat Roofing?
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
Drainage Solutions
We solve ponding water with tapered insulation systems. Minimum quarter-inch per foot slope to drains or edges. Ponding is the number one flat roof killer. We eliminate it.
Manufacturer Warranties
15-20 year manufacturer warranties on new flat roof installations. Coating systems warrantied for 10-15 years. All backed by certified installation.
All Flat Roof Systems
TPO, EPDM, PVC, modified bitumen, built-up roofing, and coatings. We install the right system for your building, not whatever we have on the truck.
About Our Doe Run Flat Roofing Services
Modified bitumen is our recommendation for residential flat roofs and high-traffic commercial applications. Two-ply torch-applied SBS system with a granulated cap sheet handles foot traffic, thermal cycling, and MO UV exposure. It's the toughest flat roof membrane for everyday abuse.
Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
