Roof Rejuvenation

Roof rejuvenation vs replacement

If your asphalt shingle roof is dry and faded but not failing, rejuvenation can add up to 18 years of life for a fraction of a tear-off. Here is an honest side-by-side comparison so you can decide.

Choose rejuvenation if

  • Your asphalt shingle roof is roughly 8–20 years old
  • Shingles look faded, dry, or brittle at the edges
  • You see granules collecting in gutters and downspouts
  • The roof deck is solid with no widespread leaks
  • You want to defer a major expense without ignoring the roof

Choose replacement if

  • There is deck rot, sagging, or structural damage
  • Shingles are missing, torn off, or shattered across the roof
  • The roof already carries multiple shingle layers
  • Leaks are active in several areas at once
  • The roof is past 25 years and the mat has failed

Roof rejuvenation FAQ

What is roof rejuvenation?
Roof rejuvenation is a treatment that sprays a bio-based, soy-derived rejuvenator into aging asphalt shingles to replace the oils that evaporate over time. Restoring those oils returns flexibility and water-shedding performance to shingles that are dry but still structurally sound. Shingle Savers pairs it with Granule Lock, which re-bonds loose ceramic granules to preserve the shingle's UV barrier.
How much does roof rejuvenation cost compared to replacement?
Rejuvenation typically runs roughly 15 to 20 percent of the price of a full tear-off replacement on the same home. Because pricing depends on roof size, pitch, and condition, Shingle Savers gives a firm number after a free inspection with photo documentation.
How many years does roof rejuvenation add?
On a structurally sound asphalt shingle roof, treatment can add up to 18 years of service life and is backed by a 6-year warranty. A full replacement resets the roof entirely with a new 20 to 30 year shingle system.
When is replacement the better choice?
Replacement is the right call when there is deck rot, widespread missing or blown-off shingles, multiple existing layers, active structural damage, or shingles that have already lost their mat integrity. Rejuvenation cannot rebuild a roof that has failed — it extends one that is aging.
Is my roof a candidate for rejuvenation?
Good candidates are asphalt shingle roofs roughly 8 to 20 years old that look faded and dry, show granules in the gutters, and have curling edges, but no widespread leaks or deck damage. Shingle Savers inspects free of charge and will tell you plainly if replacement is the honest answer.
Is roof rejuvenation safe for plants, pets, and kids?
Yes. GreenSoy is a bio-based, soy-derived product rather than a petroleum solvent, and it is safe around children, pets, landscaping, and stormwater runoff.
