Roof Repair
Flat roof repairs for homes, additions, porches and garages across London and Southwestern Ontario.
Residential flat roof leak diagnosis
Flat and low-slope sections on additions, porches, garages and dormers leak differently than shingle roofs. Water travels before it shows, so a stain in the kitchen can start at a seam ten feet away. We trace every leak to its source before we quote, then fix the cause.
Homeowners across London and Southwestern Ontario trust us with their homes, and our 4.8-star Google rating reflects how we treat them. Crews arrive on time, work clean, and leave the property tidy. Inspections are free, and we guarantee every repair we complete.

Residential roof repair FAQs
How serious is a stain on my ceiling?
It depends where the water starts, which is rarely right above the stain. A free inspection tells us the source and the fix.
Do you repair flat sections on shingle homes?
Yes. Flat and low-slope sections over additions, porches and garages are exactly what we specialize in.
How much will a repair cost?
Every roof is different, so we quote after diagnosing the leak. The inspection and estimate are free.
Will you push a full replacement?
No. If a repair is the right call, that’s what we’ll recommend. We put it in writing either way.
