The NuTopp roof rejuvenator is a penetrating bio-oil for aging asphalt shingles. It soaks back into the shingle and replaces the maltene oils lost to sun and age, restoring flexibility and granule adhesion. That's how your customer defers a full reroof.

• Penetrating bio-oil: Soaks into the shingle by diffusion instead of sitting on top like a coating.
• Replaces lost maltenes: Puts back the oil fractions that UV and heat strip out of the asphalt binder over the years.
• Restores flexibility and granule adhesion: Softens brittle shingles and helps them hold their granules, which cuts moisture permeability.
• Neutral pH, low hazard: pH 7 to 8, biodegradable, and DOT not regulated. Ships and stores easier than SH or acids.
• Add-on service: Sells as a rejuvenation upsell on the roofs you already soft wash.

Made for standard asphalt composite shingles. It won't work on wood shakes, slate, or roofs already too far gone. NuTopp isn't a soft wash additive, and you don't mix it into your SH. You clean the roof first with a low-pressure soft wash to strip mold, algae, and moss, then apply NuTopp as a separate step so it can soak in. Dilute 1 part to 3 parts water and spray at low pressure with a 12V, roof-mount, or air diaphragm pump. Mask off siding, windows, and landscaping before you spray.
