What You'll See in the Results
Colour Restoration
Faded, weathered shingles regain their original depth and richness. The difference is visible from the street.
Moss & Algae Gone
Black streaks and green moss patches are eliminated — leaving a clean, uniform surface.
Granule Retention
Treated shingles stop shedding granules — the protective layer stays intact for years longer.
Shingle Flexibility
Brittle, curling shingles lie flat again as the restored oils return flexibility to the asphalt.
