Greener Shingles asphalt rejuvenator was inspired by a patented asphalt rejuvenator for roads and parking lots. Greener Shingles was then reformulated and tested independently by PRI labs in Florida, one of the biggest Shingle and Asphalt testing labs in the world. GS was tested and proven to improve granular adhesion by 86% and unexpectedly had 40% better fire retardancy. Greener Shingles is also a USDA CERTIFIED 90% BIOBASED PRODUCT.

We maintain our asphalt driveways and roadways, why not our roofs?

Greener Shingles is a bio-based soybean oil solution that adds years of life to asphalt shingles, extending the time that the shingles would need to be replaced.


After completing a series of vigorous lab tests the Greener Shingles rejuvenator has demonstrated that it can help reduce the effects of aging after being applied to asphalt shingles, improve granular adhesion, help waterproof the surface and improve fire retardancy.

This environmentally safe solution improves shingle flexibility which helps the expansion and contracting that happens to the shingle throughout the day. Greener Shingles uses a bio-based soybean oil solution that is safe around the exterior of the home.

Asphalt roofs usually start showing signs of aging after five to ten years depending on region and environmental conditions. The shingle’s granular coating starts washing into the gutters as the essential oils dry up, losing the ability to hold the granular in place.

Asphalt shingle granular coating starts washing into the gutters (those little rocks, in your gutters) as the oil dries out, thus the shingle looses the ability to hold the granular in place, leaving it exposed to cracking and failing.

PRI Asphalt Technologies Inc, one of the largest shingle and asphalt testing labs in the world, tested Greener Shingle’s bio-based product and concluded that Greener Shingles had 86% better granular adhesion and makes asphalt shingles 40% more flame resistant. Greener Shingles also waterproofs the surface, suffocates moss, increases shingle flexibility, helps to keep granular in place, preserving the shingles last longer, keeping them on your roof where they belong.

Replacing Lost Oils

Natural agriculture oils have been used for the past 15 years to rejuvenate asphalt roads to replace the oils that are lost through years of aging.​

Increased Granular Adhesion

By rejuvenating shingles there is 86% better granular adhesion, increased shingle flexibility which helps prevent damage caused by wind and hail.

Stop Moss Growth

When applied, Greener Shingles will smother moss and algae, restricting the ability for the moss to grow further. The dead moss will wash off after a good rain or roof cleaning.
