Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Lehr Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Lehr.
Our Flat Roofing Process
Membrane Assessment
We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.
Detailed Proposal
We present options, not ultimatums. If a repair extends your flat roof 5-10 years, that might be the smartest investment right now. If the insulation is waterlogged and the membrane is failing, replacement is the answer. We lay out the facts.
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.
Warranty & Drainage Test
After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Why Choose Lehr Roofing & Maintenance for Flat Roofing?
Specialized Flat Roof Crew
Flat roofing requires different skills and equipment than sloped roofing. Our flat roof crew does this work every week, hot-air welders, torch kits, and adhesive systems are their daily tools.
Manufacturer Warranties
15-20 year manufacturer warranties on new flat roof installations. Coating systems warrantied for 10-15 years. All backed by certified installation.
Core Sampling & Testing
Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
About Our Lehr 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 ND UV exposure. It's the toughest flat roof membrane for everyday abuse.
Flat roof leaks usually happen at penetrations, seams, or flashing details, not in the middle of the membrane. We locate the source with electronic leak detection or flood testing, repair it properly, and address the root cause. If the membrane is shot, we recommend replacement, not a band-aid.
