The straight answer
Does Roof Maxx Work on an Asphalt Shingle Roof?
Yes, it works on asphalt shingles that still have life, by restoring flexibility the sun has baked out of them; it does nothing for a roof that is already past saving.
The question that decides your result is not whether the treatment works. It is whether your roof is still a candidate.

How Does Roof Rejuvenation Work on Asphalt Shingles?
Roof rejuvenation works on asphalt shingles by putting oils back into asphalt that heat and sunlight have dried out, which lets the shingles bend instead of crack.
Asphalt stays flexible because of lighter oils inside it. Years of Southern California sun drive those oils off and the shingle turns brittle.
A rejuvenator soaks into the shingle and replaces some of what was lost. That is the whole mechanism.

When Does Roof Rejuvenation Work Best?
Roof rejuvenation works best when the asphalt roof is sound, the shingles are drying out but still lying down, and nothing is actively leaking.
- Solid deck with no soft spots
- Shingles mostly intact and lying down
- Some granule loss, but no bare patches
- No active leaks
When Does Roof Rejuvenation Not Work?
Roof rejuvenation does not work when the roof is past saving, with widespread curling, bare mat showing, soft decking or leaks coming through the ceiling.
No coating on the market rebuilds a failed shingle or a rotted deck. That roof needs replacement, and an honest inspector will say so.
It also does not seal a lifted flashing or a cracked skylight curb. Those need hands-on repair.
How Can You Tell if Your Roof Is Still a Rejuvenation Candidate?
You can tell if your roof is still a rejuvenation candidate by checking for shingles that lie down, a firm deck and granules still covering the surface, and by having it inspected.
From the ground, look for curled edges and bald patches. In the attic, look for daylight or water stains.
An inspection confirms what you see and checks the flashings you cannot.
Why Does a Repair-First Tune-Up Make Rejuvenation Work Better?
A repair-first tune-up makes rejuvenation work better because the leak points get sealed and damaged shingles get replaced before any coating goes on.
Our seven-step tune-up takes a two-person crew two to three hours and carries a six-year warranty from Dura-Foam.

Rejuvenation Results FAQs
Does rejuvenation really work?
Rejuvenation really works on asphalt shingles that still have life, by restoring oils that heat and sun have removed.
Will it make an old roof new?
It will not make an old roof new; it helps a sound roof stay flexible longer.
Does it work on a leaking roof?
It does not fix a leaking roof, because leaks need repairs to flashings, skylights or shingles first.
How soon do shingles respond?
Shingles begin absorbing the treatment right away, and the flexibility change develops as it soaks in.
Does it work in hot climates?
It works in hot climates like Southern California, where sun and heat are exactly what dry asphalt out.
Is it worth trying on a roof near the end?
It is not worth trying on a roof at the end of its life, because there is nothing left to restore.
What do you do differently?
We repair flashings, skylights and damaged shingles first, then apply our coating on the same visit.
How do I know my roof qualifies?
You know your roof qualifies after a free inspection that checks the deck, shingles and flashings.
