What Roof Rejuvenation Actually Does to a Shingle.
A plain explanation of the problem, the treatment, and where the limits are — so you can decide whether an assessment is worth your time.
The problem is oil loss, not dirt.
An asphalt shingle is a fiberglass mat saturated with asphalt and surfaced with mineral granules. The asphalt is what makes the shingle flexible and waterproof; the granules protect the asphalt from ultraviolet light.
Over years of heat cycling and UV exposure, the lighter oils in that asphalt volatilise. The shingle stiffens. Granules lose their grip and wash into the gutters, which exposes more asphalt, which accelerates the process. Eventually the shingle becomes brittle enough to crack or curl.
Pressure washing does not fix this — it removes granules and makes it worse. Coatings sit on top and can trap moisture. Rejuvenation takes a different approach: put oils back into the shingle itself.
Before — dry surface, uneven tone, granule loss
After — even tone restored across all slopes

What rejuvenation is not
- It is not a repair. Leaks, flashing failures, and damaged decking need fixing first.
- It is not a coating or a paint sitting on the surface.
- It will not rebuild a shingle that has already cracked, cupped, or lost its mat.
- It is not a substitute for replacement on a roof at the end of its life.
Where it fits best
- Asphalt shingle roofs roughly 12–20 years old
- Sound deck, sound flashing, no active leaks
- Surface aging: fading, drying, early granule loss
- Homeowners who want to defer a replacement decision

The assessment is free, takes about half an hour, and comes with photographs of what we find.
