GreenSoy Technology

A bio-based rejuvenator derived from American-grown soybeans. GreenSoy penetrates deep into aging asphalt shingles, replenishing the natural oils that have evaporated under years of California sun.

  • Restores flexibility, preventing brittle cracking
  • Renews waterproofing performance
  • Safe for kids, pets, plants, and runoff
  • Sustainable alternative to petroleum-based products
Granule Lock Technology badge

Granule Lock Technology

The ceramic granules on your shingles are what protect the asphalt from UV light. Once they wash off, the clock starts. Granule Lock re-bonds loose granules so your roof stays protected for years.

  • Slows granule loss in its tracks
  • Preserves the UV barrier that prevents asphalt breakdown
  • Maintains proper thermal performance
  • Backed by a 6 year warranty up to 18 years

The Process

Start to finish in one day

Most treatments are completed in a single day with minimal disruption to your home.

  1. 01

    Free Roof Inspection

    A licensed technician evaluates your roof's age, granule loss, flexibility, and overall health. You get a clear report and honest estimate.

  2. 02

    Roof Tune Up

    We address small issues before treatment — replacing damaged shingles, resealing exposed nails, and tuning up flashing and vulnerable areas so your roof is in the best shape possible.

  3. 03

    Surface Preparation

    We carefully clean debris, and built-up material from the shingles so the treatment can fully penetrate the surface.

  4. 04

    GreenSoy & Granule Lock Application

    Our soy-based rejuvenator is professionally sprayed onto the shingles, restoring lost oils and flexibility deep into the asphalt matrix. Then a protective layer bonds loose granules back to the shingle surface, preserving the UV barrier and slowing erosion.

  5. 05

    Final Walkthrough

    We confirm the entire roof is treated, leave your property spotless, and back the work with a 6-year warranty.

Built to last another decade.

On average, our customers add 6–18 years to the life of their roof — for roughly 15–20% of the cost of a full tear-off. That's thousands of dollars saved and tons of asphalt kept out of landfills.

Roof rejuvenation questions, answered

What is roof rejuvenation?
Roof rejuvenation is a treatment that restores the oils asphalt shingles lose as they age, returning flexibility and water-shedding performance to a roof that is dry but still structurally sound. Shingle Savers uses GreenSoy, a soy-based rejuvenator, together with Granule Lock granule sealing.
What is GreenSoy roof treatment?
GreenSoy is a bio-based rejuvenator derived from American-grown soybeans. It penetrates deep into aging asphalt shingles, replenishing the natural oils that have evaporated under years of California sun. This restores flexibility, renews waterproofing performance, and is safe for kids, pets, plants, and runoff.
How does Granule Lock technology work?
The ceramic granules on your shingles protect the asphalt from UV light. Once they wash off, the asphalt begins to break down. Granule Lock re-bonds loose granules back to the shingle surface, preserving the UV barrier, slowing erosion, and maintaining proper thermal performance.
How long does the roof treatment process take?
Most treatments are completed in a single day with minimal disruption to your home. The process includes a free inspection, roof tune-up, surface preparation, GreenSoy and Granule Lock application, and a final walkthrough.
How much does asphalt shingle rejuvenation cost?
Rejuvenation typically costs roughly 15 to 20 percent of a full tear-off replacement on the same home. Because price depends on roof size, pitch, and condition, Shingle Savers provides a firm quote after a free inspection with photo documentation.
How many years does roof treatment add to my roof?
On average, our customers add 6 to 18 years to the life of their asphalt shingle roof for roughly 15 to 20 percent of the cost of a full tear-off replacement. All treatments are backed by a 6-year warranty.
Is my roof a good candidate for rejuvenation?
Asphalt shingle roofs roughly 8 to 20 years old that look faded and dry, shed granules into the gutters, and have curling edges are strong candidates. Roofs with deck rot, widespread missing shingles, or active structural damage need replacement instead, and we will tell you so during the free inspection.
Is the treatment safe for my family and the environment?
Yes. GreenSoy is a sustainable, bio-based alternative to petroleum-based products. It is safe for children, pets, plants, and water runoff, making it an environmentally responsible choice for extending your roof's life.
