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:

Asphalt Shingle Rejuvenation: Our 99% bio-based formula restores asphalt shingles; bio-based oils revive cedar shingles, extending life by years.

• Saves Thousands: Starts at $1,000, saving $10,000+ vs. replacement.

• Extends Life: Adds 5+ years per application—up to 3 applications for 15 years of protection, proven in Calgary’s UV (2,405 hours per year).

• Eco-Friendly: Our 99% bio-based, low-VOC rejuvenator saves 3 tons of shingle waste from Calgary’s landfills per home.

• Odor-Free: Dipentene-free, hypoallergenic, safe for pets/kids.

• Warranty: 5-year transferable, boosts resale value.

• Our proprietary bio-based formula uses stabilizers and UV protection for lasting results. Industry tests show enhanced granular adhesion (84% improvement) and shingle durability. A 2002 test (U.S. Pat. No. 6,495,074) restored flexibility to 20-year shingles, while Ohio State studies confirm reversed aging. Applied in 2-3 hours, our solution is tailored to Calgary’s climate.

Soft Washing: Gently clean roofs, siding, solar panels, decks, and more to remove algae and dirt.

Complete Care: Tree trimming, gutter cleaning, cedar repair, and more to protect your home.
