Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, Karthaus Roofing & Maintenance handles flat roofing in Karthaus with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.
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 PA UV exposure. It's the toughest flat roof membrane for everyday abuse.
Our Flat Roofing Process
Free Evaluation
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.
Your Options
Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.
Membrane Installation
Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.
Final Inspection
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 Karthaus.
