Algae stains are prevalent on asphalt roofs, but most homeowners don’t realize those streaks are actually a failing roof. The reduction of asphalt content in new shingles means the oils dry out much faster than they used to and that is what allows the algae roots to take hold. Shingle Saver applies the Greener Shingles proprietary formulation that re-saturates the shingle with bio-oils that choke off the root systems of the algae and prevent re-growth.
The ability to expand and contract in rapidly changing temperatures is vital to the performance of shingles. Evaporation of the petro-chemical oils results in the loss of flexibility, leading to potential cracking and even leaks. We’ll caulk and seal minor cracks before applying Greener Shingles, and that means restoring flexibility to your shingles.
Greener Shingles is made with 90% bio-based natural food-grade oils. It is safe in small quantities, easily washed off with water, but like water in a flood, it’s not 100% safe but is safe around pets, plants and people.
