Roof Rejuvenation in the Bay Area
Roof Maxx for aging asphalt shingle roofs: a plant-based oil, sprayed on to put back what the years have dried out, so a sound roof can wait longer for replacement.
Does roof rejuvenation really work?
On the right roof, yes. Roof Maxx puts back the oils that aging asphalt shingles lose, and Roof Maxx says each treatment adds about five years, up to 15 with repeat treatments. It won’t stop a leak or save a roof that’s too far gone, so we look first and tell you which yours is.

What the job includes
- We meet you at the house, look at the roof with you and tell you whether it’s a fit for Roof Maxx, or needs a repair or a new roof instead.
- If your roof needs repairs first, such as damaged shingles, flashing or vents, we quote them separately and do them before the treatment.
- We spray the treatment evenly across the roof, and it soaks into the shingles.
- We document everything and include photos.
Treat, repair or replace?
| Your roof | What usually makes sense |
|---|---|
| Asphalt shingles, aging, still whole and lying flat | Roof Maxx |
| A leak at flashing, a vent, a chimney or a skylight | A repair: Roof Maxx doesn’t seal leaks |
| 30% or more of the shingles’ granules gone | A new roof: too far along for treatment |
| Repeated problems, rot, sagging or soft spots | A new roof |
| Tile, metal, wood or a flat roof | Ask us about the options: Roof Maxx is made for asphalt shingles |
Signs it may be time
- Granules from the shingles collecting in the gutters
- An asphalt shingle roof somewhere around 10 to 20 years old
- Shingles still whole and lying flat, with no leaks

Questions people ask
Will Roof Maxx stop a leak?
No. Roof Maxx says it isn’t made to seal a roof against leaks, and most leaks start at flashing, chimneys, skylights or walls. A leak is a repair, and we do those.
How long does a treatment last?
Roof Maxx says about five years. A roof that still qualifies can be treated again, up to 15 years in all.
What’s in it?
A plant-based oil made from soybeans. Roof Maxx calls it non-toxic, and the USDA certifies it as 86% bio-based.
Will it get rid of moss?
Roof Maxx says it can help slow new moss and algae, but it won’t remove what’s already there. That’s a roof cleaning, which we also do.
How much does it cost?
It depends on your roof’s size and anything that needs fixing first. Roof Maxx’s own figures put a treatment well below the cost of a new roof. We come out, take a look and give you a free estimate.
The best time to treat a roof is while it’s still sound.
