Calgary’s 2,405 hours of intense sunshine, snow, and hail damage asphalt, cedar, and ceramic tile roofs, plus siding, decks, and solar panels, causing algae, graying, and early failure. Green Shield’s eco-friendly services save you thousands compared to replacement and keep ~3 tons of waste out of Calgary’s landfills:

Extends Life: Our asphalt shingle rejuvenation process adds over 5 years of life per application—allowing for up to 3 applications to achieve 15 years of protection, as proven in Calgary’s UV exposure (2,405 hours per year). This bio-based roof rejuvenation offers an eco-friendly roofing service that contributes to roof restoration while minimizing the need for extensive Calgary roof repair.

Solar panels

Unlike asphalt shingle rejuvenation that requires expensive removal of solar panels, our bio-based roof rejuvenation process does not. We spray under the panels, extending the life of the roof below while providing essential Calgary roof repair. Additionally, inquire about our eco-friendly roofing services, including panel cleaning and defogging, to restore efficiency.

Non-toxic

Odor-Free: With a dipentene-free formula, our hypoallergenic product is safe for pets and kids, making it an ideal choice for eco-friendly roofing services and Calgary roof repair.
