Roof Waterproofing in St. Thomas
Professional roof waterproofing in St. Thomas — 24 hour response, licensed & insured.
Flat and low-slope roofs in St. Thomas need real waterproofing, not shingles. We install and service modified-bitumen, EPDM, and TPO membrane systems, seal every seam and penetration, and pressure-test the finished surface.
Why roof waterproofing matters in St. Thomas
Flat Roofs Are Different
Shingles rely on gravity. Flat roofs rely on a continuous waterproof membrane — a totally different install skill set.
Seams Are Everything
80% of flat-roof failures are at seams. Torch-welded or heat-welded seams properly executed are what separates a 5-year roof from a 25-year roof.
Drainage Design
Ponding water on a flat roof accelerates membrane failure. We correct slope and drain sizing before laying new material.

Roof Waterproofing reviews in St. Thomas
No call centre, no chasing. Booked in two minutes and got a text when the truck was on the way.
Photos, readings, and a written summary after every visit. Makes it easy to keep records for the house file.
Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.
Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.
FAQ
