Working with Massimo Rovella from Guardian was nothing short of exceptional. From the very first conversation, Massimo demonstrated professionalism, deep expertise, and a genuine commitment to making sure we felt confident every step of the way in purchasing our new roof.
He took the time to clearly explain options, materials, timelines, and costs in a way that made the entire process feel transparent and stress-free. There was zero pressure — just honest guidance and thoughtful recommendations tailored specifically to our home. Massimo made what could have been a complicated decision feel simple and even enjoyable.
What truly stood out was his responsiveness and attention to detail. Every question was answered quickly and thoroughly, and he consistently went above and beyond to ensure we felt supported and informed. It’s rare to find someone who combines technical knowledge with such strong customer care skills.
Guardian is fortunate to have Massimo representing their company. His integrity, professionalism, and commitment to excellence made this an easy decision for us, and we feel extremely confident moving forward with our new roof.
If you’re considering a roofing project, ask for Massimo Rovella — you’ll be glad you did. Outstanding experience from start to finish. Highly recommend! 🏠👏
I had the pleasure of working with Cody for my roofing project, and I couldn't be happier with the sales experience. From the first consultation, he was professional, knowledgeable, and genuinely committed to finding the best solution for my home.
Cody took the time to explain all my options, ensuring I understood the materials, pricing, and timeline. No pressure—just honest guidance. The communication was seamless, and every question I had was answered promptly.
If you’re looking for someone who is reliable, personable, and truly cares about their clients, I highly recommend Cody!
Post installation update:
Adjusted stars from 5 to 1...
I contracted Guardian to apply the Cericade roofing coating/sealant to my home. Prior to signing, I was shown product samples that appeared solid and opaque. Since I was unfamiliar with Cericade, I requested addresses of homes where it had been previously installed so I could view the results firsthand. All the examples provided featured the black coating.
My original shingles were a tan/weathered wood color, but based on the samples, references, and being told tge color would be solid, I proceeded with the black Cericade application.
Shortly after signing, Guardian reached out to confirm the payment schedule—deposit due at the start of work, with the balance due upon completion—and provided a tentative timeline. Communication at this stage was prompt and professional.
The schedule shifted a few times due to weather and equipment issues, which I found understandable.
However, after the coating was applied, the crew left without notifying me that the job was complete or offering a walk-through. The finance team contacted me quickly for the final payment. At the time, the sky was overcast, and the roof appeared uniformly black.
A few days later, I noticed that in full sunlight, the coating was not truly opaque. The black finish was fairly translucent, except in areas where overspray occurred—resulting in noticeable vertical lines across the roof.
I’ve reached out to Guardian multiple times to discuss these concerns, but no one has followed up or come to inspect the issue.
Given this experience, I would not choose to install this product again.
Update 11/10/2025:
After updating my review on 10/9, Guardian was very responsive. They had been working on things with the product vendor but had not communicated that to me. The original coating batch was "light" on pigment so the manufacturer supplied new product to be applied.
The coating was reapplied on 10/14. The color is much more even and solid/opaque. There are some lines from where the product was overlapped but overall it looks much better than the original application.
I updated the rating to 4 stars.
