About Us

Certified Roof Maintenance Inspections Backed by Experience

British Columbia is a beautiful place to live, but we have some of the wettest and also some of the driest climates in Canada. 

Knowingly, any roof on earth should be checked at least on an annual basis for its functionality, wear and damages. Commercial properties may require seasonal inspections depending on style, location, and its use.

From low-slope to steep-slope and conventional to inverted roofing systems, a visit from a qualified roof inspector will establish your asset’s condition and ease your mind.

If you have questions or concerns about what’s overhead, Applied Roofing Science is happy to help.
