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. Corwith Roofing & Maintenance has been installing flat roofs in Corwith for 18 years. We know what works and what doesn't in IA's climate.
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.
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.
Professional Installation
Our flat roof crew installs per manufacturer specifications and NRCA guidelines. TPO seams hot-air welded and probe-tested. Modified bitumen torch-applied in two plies. EPDM fully adhered with proper lap adhesive. Tapered insulation installed to create positive drainage.
Final Inspection
Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.

About Our Corwith Flat Roofing Services
PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Corwith, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Every flat roof Corwith Roofing & Maintenance installs includes proper drainage design. Tapered insulation, cricket saddles around rooftop equipment, and properly sized drains or scuppers ensure water moves off the roof, not into your building. Ponding water voids many manufacturer warranties. We eliminate it.
