Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, Castell Roofing & Maintenance handles flat roofing in Castell with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.
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 Castell, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Our Flat Roofing Process
Free Evaluation
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.
System Recommendation
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
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.
