A promising idea.
A decision grounded in evidence.

Start with the exact treatment.

PSP Nano Roof Protection is our service using NexaNano’s roof treatment. PSP is the service brand. NexaNano makes the underlying product. A claim about another nano product doesn’t automatically tell you what to expect from your roof. Neither does a result from another surface or installer.

Water beading shows surface behavior under the conditions you can see. A useful roof decision also considers the roofing system’s condition and the written guidance for its materials.

NexaNano · manufacturer information

The treatment technology

NexaNano describes a silicon dioxide (SiO₂) treatment designed to repel water while allowing a treated surface to remain breathable. This explains the intended mechanism. It doesn’t establish the remaining life of an individual roof.

The roof-specific product

The manufacturer markets Roof Protect for certain roofing materials and describes protection against moisture and UV exposure. Ask for current application instructions and evidence for the exact product and roofing material being proposed.

Asphalt Roofing Manufacturers Association · industry guidance

The shingle industry’s position

ARMA advises against applying coatings or rejuvenators over installed asphalt shingles and recommends consulting the shingle manufacturer. That position makes written, product-specific compatibility guidance a necessary part of the decision.

What do other homeowners say?

NexaNano publishes homeowner and installer testimonials across several surfaces. Some concern concrete, and one describes a roof and driveway in Utah. They’re supplier-published accounts, not PSP jobs or independent proof of roof longevity. We haven’t independently verified those experiences.

PSP’s own customer stories will identify the work PSP performed and the observations we can document. We won’t treat a supplier’s testimonials as a PSP track record.

Five things to put beside your quote.

1. The roof assessment, with photographs and a description of any repairs needed.
2. The exact treatment name and current technical and application documents.
3. Written guidance from the maker of your roofing material about compatibility.
4. Any treatment warranty, including exclusions, registration, remedies and who provides it.
5. A complete scope and price that distinguish preparation and repairs from the treatment itself.

Laboratory findings, when supplied, should identify the tested material and method. Long-term field claims need evidence of time in service. Neither should be replaced by a general marketing promise.

Make the next step practical.

You don’t need to become a roofing expert. Start with what you know, flag what needs an answer, and compare the complete options before committing.

Use the roof suitability guide or compare written quotes. The tools help organize your questions. The assessment determines the recommendation.
