Protecting Arizona homes, one smart solution at a time.
Roof Guard Pro is run by Stephen Zweig out of Apache Junction, Arizona. One job: give you a smarter, affordable choice that preserves the roof you already have instead of replacing it.

Hello, I'm Steve. This is my better half, Stephanie.
We're a locally owned and operated business, proudly based right here in Apache Junction, Arizona. As Arizona homeowners ourselves, we know what our desert sun does to a house — the intense heat and relentless UV degrade asphalt shingles over time, causing cracking, severe granule loss, and premature leaks. For years, the only solution was a loud, messy, and incredibly expensive roof replacement.
I founded Roof Guard Pro to give you a smarter, affordable choice that preserves your roof instead of replacing it. Customers name me personally in almost every review on Google, because that is who shows up: no call centers, no rotating crews, no upsell.

A deeper level of protection with NexaNano.
As a NexaNano Certified Installer, I use a revolutionary, oil-free silicon dioxide (SiO₂) nanotechnology formula that bonds at a molecular level — and it is made right here in the United States, in Payson, Utah.
- Roof Protect — forms an invisible, hydrophobic barrier that locks down shingles, halts granule loss, blocks severe UV rays, and adds 10 to 15 years of useful roof life
- Concrete & Stone Protect — seals driveways, walkways, and patios against cracking and heavy vehicle staining
- Wood Protect — shields fences and decks from severe sun fading, water intrusion, and rot
Best of all, NexaNano is completely eco-safe, oil-free, biodegradable, and contains zero VOCs — making it entirely safe for your family, pets, and landscaping.

One visit, one treatment, done.
A typical residential roof is treated in a single visit. We walk it first, take before photos, spray the NexaNano Roof Protect with the right technique for your shingle age and pitch, and hand you documentation on the treatment and the 10-year manufacturer warranty. If concrete and wood are on the list too, we can bundle everything into one trip.
“Stephen was true to his word and performed the roof coating in some of the hottest weather conditions. When we found a small leak after a rain storm Stephen came back and repaired the area. Everything has been good ever since.”
