Why rejuvenate your shingles?

  • Increases adhesion of the protective top granule coating

  • Restores shingles flexibility reducing cracking and lowering chance of wind related shingle damage
  • Restores permeability closer to new shingles

  • Greener Shingles is a bio-based, environmentally friendly soy product, lab tested to replace essential oils in asphalt shingles and make them last longer

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 waterproofs the surface, suffocates moss, increases shingle flexibility, helps keep granular in place, and improves fire resistance, making the shingles last longer, keeping them on your roof where they belong.

After completing a series of vigorous lab tests the Greener Shingles solution has demonstrated that it can help reduce the effects of aging after being applied to asphalt shingles.

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

Greener Shingles Rejuvenator has been lab tested and field proven to decrease the affect of hail damage, makes asphalt shingles 40% more flame resistant, and improves granular adhesion by 86%.


1. Roof Inspection and setup

2. Application takes about an hour

3. Longer Lasting Shingles, improved granular adhesion and waterproofing



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.

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.


A: Greener Shingles is made with 92% 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.

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.

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

A: Yes, the color will darken, similar to what it was when new. Within a month or two it will start to lighten up as the surface oil starts to oxidize off and within a couple years it will be back closer to the color of the shingles the day the roof was sprayed.

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.

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.

A: It depends on the size, pitch and access of the roof. It costs about 15% of the cost of replacement, or saves 85% of the cost of replacing. Contact your local dealer for an estimate.

Did you know that nearly 11 million tons of asphalt shingles make their way into landfills every year?

Shingle rejuvenation extends the life of asphalt shingles, keeping shingles on roofs and out of the landfills.
