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. Greener Shingle's bio-based product was tested and proven to have a 86% better granular adhesion on treated shingles versus untreated.

Greener Shingles helps waterproof the surface, suffocates moss, increases shingle flexibility, helps keep granular in place, and improves fire resistance, preserving and rejuvenating the shingles to last longer, keeping them on your roof where they belong.



Soy bean oil based rejuvenators have been used to rejuvenate asphalt parking lots and roadways for the past fifteen years, making it the number one asphalt rejuvenator in the USA. Greener Shingles has adapted that same rejuvenator to extend the life span of asphalt shingles.

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 quickly restores your roof's flexibility and waterproofing protection, while also reducing the loss of the shingle's protective top granule coating.

Q: Is Greener Shingles safe?

A: 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.  

Q: What temperatures are required to put this on my roof?

A: Typically we suggest the temperature be at least 39-41 degrees or 4 to 5 degrees above freezing and rising with no rain in the forecast for 45 minutes.

Q: Does this help with moss and algae growing on my roof?

A: Yes, we suggest cleaning the roof first, then rejuvenating with Greener Shingles. Any moss or algae left will be smothered and killed. Check out the before and after pictures in the gallery.

Q: Does Greener Shingles change the color of the shingles?

A:Yes, the color of the shingles will darken, similar to what it was like when new. Within a couple of years the shingles will start to lighten up as the surface oils begin to oxidize off.

Q: What does the warranty cover?

A: Our five year prorated warranty covers the fact that GS will extend the life of the shingle five years past the expected life of the shingle in the environment they are in. Some owners want to stop the aging process on older shingles, so depending on how old they are we may not be able to warranty a shingle that is starting to show signs of extreme aging, like when the shingles are starting to curl up. The warranty is transferable to the next homeowner.

Q: How do I know if my shingles need rejuvenation?

A: Typically shingles that are ten years old start to show signs of aging, granular loss and could use rejuvenation before they start to curl up and become brittle.

Q: How much does it cost?

A:  Typically, shingle rejuvenation costs 15% of the cost of replacement. An average cost of roof replacement in 2020 was $10,000 compared to only $1,500 to rejuvenate.
