Flat Roof Leak Repair for Commercial Buildings

Specialized leak repairs for flat and low-slope commercial roofing systems including TPO, EPDM, PVC, and modified bitumen membranes.

Common Flat Roof Leak Challenges

Flat commercial roofs face unique leak challenges due to minimal slope and water drainage patterns. Understanding these specific issues allows for targeted, effective repairs.

Ponding Water Issues

Water that remains on flat roofs for 48+ hours accelerates membrane degradation and creates consistent leak pathways. We address both the leak and underlying drainage problems.

  • Structural assessment for low spots
  • Drain evaluation and cleaning
  • Tapered insulation solutions when needed

Membrane Seam Failures

Single-ply membrane seams can separate due to thermal movement, installation defects, or age. These failures create direct water entry paths requiring specialized repair.

  • Heat-welded seam repairs for TPO/PVC
  • Tape and adhesive repairs for EPDM
  • Manufacturer-approved methods

Penetration & Flashing Leaks

Rooftop equipment, vents, and transitions require complex flashing details. Failed flashing is one of the most common flat roof leak sources.

  • HVAC unit base flashing repair
  • Parapet wall flashing replacement
  • Pipe boot and vent resealing

Membrane Punctures & Tears

Foot traffic, equipment installation, and hail can puncture single-ply membranes. These localized failures require membrane-specific patch procedures.

  • System-matched patch materials
  • Proper surface preparation
  • Warranty-compliant application
