Warning Signs
Signs You Need Flat Roof Repair
Don't wait for small issues to become expensive disasters. Here's what to watch for:
Ponding Water After Rain
Standing water is the #1 enemy of flat roofs — it accelerates membrane breakdown and creates mold risk within days.
Membrane Blisters or Bubbles
Blisters in TPO or EPDM mean the membrane has delaminated from the substrate — a precursor to full failure.
Open Seams or Splits
Flat roof seams pull apart over time. Even a 1-inch open seam lets gallons of water into the building per rain event.
Drain Blockages & Slow Drainage
Clogged roof drains cause ponding that weighs hundreds of pounds and stresses the entire roof structure.
How It Works

FAQ
Common Questions
We repair all major flat roofing systems in your area: TPO, EPDM, modified bitumen, built-up (BUR/gravel), and torch-down roofing. We inspect and diagnose before recommending any repair.
Key signs: water stains on interior ceilings, visible blisters or bubbles on the membrane surface, open seams, standing water 48+ hours after rain, and cracked or missing flashing.
Most flat roof issues can be repaired in sections — a patch, seam weld, or localized membrane replacement. Full replacement is only needed when 30%+ of the membrane is damaged.
Most flat roof repairs range from $400–$2,500 depending on the size and cause of damage. We provide a free written estimate before any work begins.
A properly executed repair with quality materials typically lasts 5-10 years. We back all repairs with a 2-year workmanship warranty — if the same area leaks again, we fix it at no cost.
