Commercial Roof Repair — FAQs

Do you offer same-day leak service?

Yes, we prioritize active leaks with same-day or next-day dispatch in Greater Calgary, weather and access permitting.

Will repairs keep my manufacturer warranty intact?

We use manufacturer-approved materials and details. If your roof is under warranty, we’ll follow required procedures and documentation.

How do you diagnose hard-to-find leaks?

We combine moisture mapping, seam probing, targeted water tests, and, when needed, IR or core sampling to find the true water path.

Repair vs replacement — how do I choose?

If damage is localized and the membrane is serviceable, repairs plus maintenance are cost-effective. Widespread saturation, aged membranes, or major design issues may justify a replacement plan.
