Roof leak investigation for intermittent and hard-to-find water entry.
Serving Toronto and communities across the GTA. We inspect first, explain the options, and put the proposed scope in writing.
The place water appears indoors may not be where it entered the roof. We work backward from the stain, consider wind direction and snowmelt, and inspect nearby transitions, penetrations, and roof surfaces before defining a repair.
Tell us what you are seeing, where the property is, and whether water is entering the home.
We inspect the affected roof areas and the details most likely to be causing the problem.
You receive a clear scope describing the proposed work, materials, and known cost factors.
Once you approve the estimate, we confirm timing and explain how to prepare the property.
Our crew completes the approved scope and documents important findings uncovered during the work.
We remove job debris, check the work area, and review the completed scope with you.
Simple leaks and complex intermittent leaks require different investigation. We explain the diagnostic and repair scope in writing.
We only label photos as True North Roofing projects after the location, work scope, and image pair have been verified.
Verified before-and-after pairs for this service have not been added yet. You can still see work shared directly through our official Instagram feed.

Wind can push rain beneath a weak flashing detail from one direction, while snowmelt can follow a different path. Matching the leak to weather conditions helps narrow the likely entry point.
Yes. Water can travel along decking, framing, pipes, or insulation before it drips. That is why sealing the roof directly above a stain does not always solve the problem.
Controlled testing may help in suitable conditions, but it is not right for every roof or active interior. We first inspect the likely paths and explain whether testing is useful and safe.
Sometimes concealed damage cannot be confirmed from the surface. If investigative removal is recommended, we describe that step and the restoration scope before proceeding.
Yes. Attic condensation, plumbing, and mechanical exhaust can create similar symptoms. We compare the timing and visible conditions, then tell you when the evidence points beyond the roof covering.
