A Revolutionary Advancement In Roof Maintenance

Roof Rejuvenate is not a typical roof sealant or cleaning product. We treat your roof with a scientifically formulated, all natural, agricultural bio-oil solution that re-saturates dried, brittle shingles and restores and extends their life. It's totally safe and clean, and saves property owners thousands of dollars vs. replacement, guaranteed.

A Proven Technology

Agricultural oils have been used for nearly 20 years to extend the life of asphalt pavement. These oils maintain the flexibility of pavement and prevent brittleness which leads to cracks and potholes. Departments Of Transportation in the US and Canada use this technology to extend the life of asphalt roadways and save on maintenance and replacement costs. Our supplier, Greener Shingles, has re-formulated this treatment and made it available for asphalt shingle roofs.  

How It Works

As asphalt shingles age, the petro-chemical oils that maintain the shingle's flexibility and performance begin to evaporate, and problems begin to develop. Roof Rejuvenate applies an all-natural bio-based solution that replaces lost petro-chemical oils, bringing the shingle back to life. The first application is guaranteed to extend the life of your roof by 5 years. 

What Roof Rejuvenate Treatment Does

  • Rejuvenates aging asphalt shingles so they don't have to be replaced
  • Extends the life of the shingles by 5-15 years
  • Restores flexibility by 86%
  • Reduces damage caused by wind and hail
  • Restores shingle color
  • Kills algae and moss, and hinders re-growth
  • Keeps shingles out of landfills (more below)
  • Improves fire resistance by 40%.
  • Locks in granules and reactivates adhesives

Lab Tested

Independent testing by PRI Asphalt Technologies compared treated vs. untreated shingles with the following findings:

  • Granular adhesion improved by 86%.
  • Flexibility improved from "fail" to "pass".
  • Hail impact was improved.
  • Fire resistance improved by 40%.

Environmental Impact

In the US alone, over 11 million tons of asphalt shingles are dumped into landfills every year.  Due to cost and difficulty of recycling, most shingles are never recycled, increasing the potential for negative environmental impact to air quality (shingle dust) and water quality (seepage of petro-chemicals into ground water).  Every roof saved by Roof Rejuvenate is one less in the landfill.   


Most asphalt roofs show some signs of drying out between 6 and 10 years of age, depending on region and intensity of the Sun’s UV rays.

When the shingles’ protective top layer of granule coating begins shedding off into the gutters. This coating functions as a sort of “sunscreen” for your shingles. The oil contained within the shingles is essential for maintaining this coating, but as it dries out, the shingles will start to become brittle and crack.

Black stains and streaking on the shingles is another sign that the roof is aging. Most roofs with staining are shedding the protective top coating to varying degrees. Note: Staining does not harm the roof and is only an aesthetic issue.

Yes. The products Roof Rejuvenate uses is ECO-Friendly and 100% safe for people, pets, property, and the environment, because it’s an all-natural food-grade product. Any overspray is rinsed away with a hose or rain.

Roof Rejuvenate, LLC, proudly warrants that the treated asphalt shingles will perform as originally designed and warranted by the shingle manufacturer for a period of at least five (5) years from the date of your treatment.

The Roof Rejuvenate Warranty is still valid even if your manufacturer’s warranty is (or becomes) void due to time or transfer restrictions.

This is not a warranty against leaks from faulty installation or other damage sustained by the roof (hail, high winds). However, if under normal operating & weather conditions the treated shingles lose their proper operating flexibility, granular adhesion characteristics, or structural integrity or performance, Roof Rejuvenate will retreat all affected areas on a simple prorated basis (over 60-month warranty period).

Temperature: It must be above 36 degrees for application.
Rain: Quickly penetrates the shingle’s top layer and begins soaking in typically 1 hour. There is no need for concern about it being washed away by the rain once it has been absorbed by the shingles.

Will bring your shingles back closer to their original color. Most shingles lighten in color as the oil drys out. This natural oil resaturates your shingles, which helps to restore their color.
