Roof Repair Services
Found the leak,
fixed it properly
Roof leak repair in London Ontario. We find where the water’s actually getting in, fix that, and stand behind it.
We diagnose before we quote
A leak rarely shows up where it starts. Water travels along decks, seams and flashing before it ever reaches your ceiling. That’s why every repair we do begins with an accurate diagnosis: we trace the leak to its source before we quote, so you pay to fix the problem, not the symptom.
We repair roofs across London and Southwestern Ontario. Flat and low-slope is what we know best (EPDM, TPO, modified bitumen), but flashing and metal repairs come up too, which is where the sheet metal side of the business earns its keep. We aim to get back to you on a leak call the same day, and any repair we finish is guaranteed.

Leaks and membrane damage on flat and low-slope home roofs.

Roof repair FAQs
How do you find where a leak starts?
We inspect the whole roof (seams, flashing, drains and penetrations) and trace water paths back to the source before quoting anything.
Do you charge for the inspection?
No, inspections and quotes are free, always. You’ll know what’s wrong and what it costs before you decide anything.
Repair or replace the whole roof?
If the deck is sound and damage is localized, a repair usually makes sense. We’ll give you an honest recommendation either way.
What areas do you serve?
London and across Southwestern Ontario, including St. Thomas, Strathroy, Sarnia and Windsor.
