Roof Rejuvenation

Roof Rejuvenation

Rejuvenation is a deep-cleaning process that removes black streaks, organic growth and debris, then replenishes your asphalt shingles with a soy-based restorative treatment. It brings back much of the roof's original look and can help extend its service life. It is maintenance for a sound roof — not a repair for a failing one.

Included

What's in the Job

  • Free estimate first — we confirm the roof is a candidate before recommending treatment
  • Low-pressure cleaning to remove black streaks, algae, moss, organic growth and debris
  • Clearing of debris from valleys and the roof surface
  • Application of a soy-based restorative treatment across the shingle field
  • Protection of plants and landscaping around the drip line during application
  • Photo documentation of the roof before and after
  • If repairs come up (damaged, missing or lifted shingles, flashing, leaks), they go in a separate written estimate

Materials

Options and Trade-offs

A plant-based treatment applied to asphalt shingles after cleaning. It replenishes oils that asphalt loses to heat and UV over time, which helps shingles stay flexible and hold their granules.

Advantages

  • Replenishes oils lost from ageing asphalt shingles
  • Improves granule adhesion on shingles that are starting to shed
  • Helps reduce premature cracking and drying
  • Can help extend the life of a roof that is otherwise sound, at a fraction of the cost of replacement
  • Restores much of the roof's original appearance

Trade-offs

  • Not a repair — it does not fix leaks, missing or broken shingles, failed flashing or storm damage
  • Only suited to asphalt shingle roofs that still have useful life left; a roof at the end of its life needs replacement, not treatment
  • How much life it adds depends on the roof's age, condition and exposure — we will not promise a number of years
  • Compatibility with a shingle manufacturer's material warranty varies by manufacturer — check your warranty terms before treating
  • Organic growth can return over time in shaded, humid conditions; periodic maintenance may be needed
