Flat Roofing FAQ

Questions homeowners ask us

Why is water pooling on my flat roof?

Ponding can result from blocked drainage, settled insulation, deck movement, or insufficient slope. We inspect where water collects and how it reaches drains before recommending maintenance, a localized correction, or a larger rebuild.

Can a flat roof be repaired?

Often, when the membrane and insulation around the failed detail remain serviceable. Widespread moisture, repeated seam failures, or extensive deterioration can make replacement more sensible. An inspection helps separate a local defect from a system-wide problem.

What flat-roof material do you use?

The right membrane depends on the building, existing assembly, slope, transitions, and access. We specify the proposed material and installation method in the written estimate rather than presenting one system as the answer for every roof.

How do you find a flat-roof leak?

We inspect seams, penetrations, parapets, drains, visible wear, and the path water may take below the surface. The interior drip can be far from the entry point, particularly where water travels across a deck or vapour barrier.

How often should a flat roof be checked?

Check after major storms and whenever drainage changes or a leak appears. A planned inspection can also catch blocked drains, open seams, and deteriorated flashings before they cause more extensive water damage.
