GoNano reviews — the Fresno version.
What GoNano actually claims, what to check before you buy from anyone, and real reviews of the authorized dealer in Fresno.
How to read GoNano reviews
If you search for GoNano reviews you will find two kinds: national testimonials on GoNano's own site, and scattered homeowner comments that rarely say what roof, what climate, or who applied it. Both miss the thing that matters most in Fresno: our sun. A treatment that performs well in a mild climate is being asked to do a much harder job on a shingle roof that hits 150 degrees in July. That makes the applicator's prep work — and their honesty about whether your roof is a candidate at all — the biggest variable in any review you read.
What GoNano itself claims
- A nanotechnology treatment that penetrates the material and changes it from within, rather than sitting on the surface like a coating
- One treatment, completed in one day, with no dust or odor
- Extends the lifespan of the roof by 10 to 15 years
- A formal, transferable written warranty on every NuRoof treatment installed by a certified GoNano contractor
- Products for asphalt shingle, concrete and tile, membrane roofs, concrete flatwork, stucco, masonry and wood
Those are GoNano's statements, quoted from GoNano. We do not add to them. What we add is a roofer's judgment about which Fresno roofs should get the treatment and which should not.

Reached out to Nick for a leak on my roof, his communication was prompt and came out the same day to quote. He is very knowledgeable and provided a competitive quote. The roof looks great and he'll be back to replace some additional broken tiles. An honest and good guy to work with, highly recommend.
Did a great job replacing 12 broken tiles and cleaning up many years of build up debris from the nearby redwood trees. Next project will be replacing my old water heaters. Professional, reliable, communicative, quality work finished timely
Excellent business and customer service. I needed some minor tile replacement and sealant on my roof. They were very professional, kind, and got my roof repaired within 2 days of speaking with them. I would definitely recommend them to a friend and plan on using them again in the future.
I had a leak in my roof and Nick was recommended to me. He gave me a quote and had his crew out to fix it the following day. He was professional and made sure that I had his contact information in case of questions or concerns. The crew arrived when he said they would and completed the job, even replaced some of the tiles that were cracked outside of the leak area. They left the area tidy, removing all the debris from the repair. I would call him again for any repairs on my house.
These guys did an amazing job on our roof. Great work. Informative staff. Very competitive pricing. Would recommend to friends and family. Definitely would use their services again!
Nick was in my area and came out and checked where my roof was leaking within an hour of me calling him. He checked it out, told me what needed to be done and gave me a reasonible estimate. Since he could schedule my repair for a few days, he placed a tarp over the problem area, until he had time to do the repairs. Really nice guy , very helpful, and his estimate was reasonible.
The questions people search before they call.
Are GoNano reviews online trustworthy?
Some are, some are marketing. The useful ones name the roof type, the roof's age, the installer, and what happened a year or two later. A review that says 'great product' the day after application tells you nothing. Judge the installer as much as the product — the same treatment on a badly prepped roof performs very differently.
Is GoNano legit?
GoNano is a real nanotechnology product line sold and applied through certified dealers, with a formal, transferable written warranty on NuRoof treatments installed by a certified contractor, and GoNano cites independent third-party testing. Whether it is the right call for your specific roof is a separate question — that is what the free inspection answers.
Who is the GoNano dealer in Fresno?
Nick Alvarado, owner of Central Valley Home Upgrades, is an authorized GoNano dealer serving Fresno, Clovis and the Central Valley. He has been a roofing contractor here since 2010 with 50+ Google and Yelp reviews averaging 4.9 stars.
What should I ask before buying GoNano?
Ask to see the written warranty for your roof type. Ask what repairs are needed first and whether they are in the price. Ask for before-and-after photos of local jobs. Ask the installer whether your roof is actually a candidate — and be suspicious of anyone who says yes without going up on it.
