Greener Shingles is an asphalt shingle rejuvenation service that replaces the oils and resins that have been lost on an aging roof. Asphalt roofs usually start showing some signs of aging after five to ten years depending on region and environmental conditions. The shingle’s granular coating start washing into the gutters as the essential oils dry up losing the ability to hold the granular in place. Greener Shingles is a powerful, scientifically formulated treatment that’s derived from soybean oil. This plant-based oil quickly penetrates deep into brittle asphalt roofing shingles. The powerful all-natural formulation helps to quickly restore your roof’s flexibility and waterproofing protection, while also reducing the loss of the shingle’s protective top granule coating.
