A flat roof that ponds water is a flat roof with a problem. Standing water degrades membrane material, compresses insulation, and finds every weak point in the system. Sibley Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.
Our Flat Roofing Process
Flat Roof Inspection
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.
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.
Expert Flat Roof Crew
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.
Warranty & Drainage Test
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.

Why Choose Sibley Roofing & Maintenance for Flat Roofing?
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.

About Our Sibley 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 IL UV exposure. It's the toughest flat roof membrane for everyday abuse.
