EPDM, TPO, and SBS flat roof repair — proper diagnosis, matched membrane, and detail work at drains, pipes, and penetrations.
Flat roof leaks are rarely where the water shows up — tracing an SBS, EPDM, or TPO membrane failure back to its actual source takes real diagnostic experience. SwiftBuild repairs all three major flat roof systems, matched by brand and type, with proper attention to drains, penetrations, and flashing detail.
We trace membrane failures to their real source before any repair begins — not just patching the visible symptom.
Patching and seam repair for EPDM rubber membrane roofs.
Heat-welded repairs for TPO membrane roofs, matched to your existing system.
Torch-applied or cold-applied repair for SBS and modified bitumen roofing systems.
Re-sealing and repair around roof drains, pipe boots, and other penetrations — among the most common flat roof leak points.
Reflective roof coating and PMMA liquid-applied flashing with fleece reinforcement for detail areas that sheet membrane can't properly seal.
Repair work rewards experience — the difference between a fix that lasts and one that fails again in a year comes down to how it's actually done.
Flat roof leaks often show up far from their actual source — we trace it properly before repairing.

We trace the leak or membrane failure to its actual source, which is often not where water is showing up inside.
The affected section of membrane — EPDM, TPO, or SBS — is removed.
Decking underneath is checked for water damage and rot.
Any compromised decking is replaced before the new membrane goes on.
New membrane matched by brand and type to your existing roof system, properly sealed or heat-welded at the seams.
Drains, pipe penetrations, and flashing points are resealed — often using PMMA liquid flashing with fleece reinforcement for a fully watertight detail.
Where appropriate, a reflective roof coating is applied to extend the life of the surrounding membrane.
