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. Leetsdale Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.
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
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.
Professional Installation
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.
Completion & Warranty
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.
