No. A roof coating forms a film that sits on top of the roof. Rejuvenation is a diluted treatment meant to soak into asphalt shingles, and SoyLei, the maker of the product we use, says it is “not a roof coating”.
How they differ
| Roof coating | Rejuvenation, as SoyLei describes it | |
|---|---|---|
| Where it goes | Forms a layer on the surface | Meant to soak into the asphalt |
| Usual roofs | Often flat and foam roofs | Asphalt shingles only |
| What you see | A new surface over the old one | The same shingles, sometimes a little darker |
What SoyLei says
SoyLei Innovations, based in Ames, Iowa, calls APEX-1132 “a spray-applied rejuvenation treatment, not a replacement for repairs or a film-forming roof coating.” It is made with semi-epoxidized soybean oil and diluted with water before it is sprayed. Those are the maker’s descriptions, and we pass them on as such.
The terms get blurred because both go on with a sprayer, and some companies sell coatings for shingle roofs too. If anyone quotes you for a roof treatment, ask which one it is and what is actually in the product.
Why the difference matters
Shingle makers are wary of both. Owens Corning’s August 2026 bulletin covers rejuvenators and coatings together. It warns that a coating over shingles “may have the potential to trap moisture that is present.” Some shingle makers, Owens Corning among them, advise against field-applied rejuvenators too, and a treatment can affect your shingle warranty. So “it’s not a coating” doesn’t settle every concern. Check with your shingle maker first.
If your roof is foam, recoating may be exactly what it needs, from a roofer who does that work. We don’t. See our tile and foam roofs page, read about the soy-based roof treatment, or book a free roof evaluation for a shingle roof.
