About Us

Who We Are

Green Shield Bio-Tech is a Calgary-based company focused on eco-friendly roof rejuvenation. We specialize in bio-based treatments that restore asphalt and cedar shingles instead of replacing them too early.

Many roofs are replaced years before they truly need to be. This creates thousands of tons of waste and costs homeowners $15,000 to $20,000 or more.

We believe there is a smarter solution.

Why us

Why Roof Rejuvenation Matters in Calgary

Calgary’s strong sun, heavy snow, and hail damage shingles over time. UV rays dry out roofing materials and cause cracking and granule loss.

Our bio-based roof rejuvenation treatment helps reverse that damage. Instead of tearing off your roof, we restore it.

This saves money, reduces waste, and gives homeowners peace of mind.
