Looks gorgeous. I am so pleased with both Chad and Josh! I had possibly the worst experience ever with KNE Customs LLC. My living room ceiling fell down just 90 days after the roof was installed. Had to take a leap of faith to try again. Thank you for listening. Fantastic crew. I’m looking forward to finally enjoying the peace a quality roof can provide.

I reached out to Guardian this spring about having some of my cedar siding replaced on the side of my house. They had somebody out to the house within a week to walk me through my options and provide a quote. I worked with Mike, and he was very responsive in his communication and very easy to work with. The crew came replaced all the siding that was rotting and needed replaced. I got some other quotes, and Guardian was the most competitive of the quotes I received. Very knowledgeable staff!

Exceptional sales experience but no customer service after installation and payment.
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.

Job Scope:
Phase 1: Replace cedar roof on the south side of my home.
Phase 2: Renovate and protect the north and east sides, which were well-preserved despite their age.
Ratings:
Commercial & Customer Service: 5/5
Job Delivery to Expectations: 5/5
Walk-out Check-up and Resolution: 5/5
I'm very particular about anything I undertake and demand high-quality work. that being said, I pointed out a few issues to the project manager, Nick, who promptly addressed them to ensure satisfaction. In summary, I highly recommend Guardian because their management stands behind their team and work—an essential factor when undertaking home remodeling or major maintenance like in this case.

Cody was very personable and thorough in his presentation of the Guardian Roofing Company. We actually decided to go with Guardian because of Cody and his willingness to meet with us several times throughout our decision process. He answered our questions completely. We are hoping that our roofing job will be as great as Cody represented the company. Made a great friend!!! Thank you

My husband and I made a very wise choice to have Guardian put on our new roof. Their workmanship is superior and their materials are the best! I certainly would recommend them to everybody. They did our whole roof rip off and put the new roof on in five hours and they did a superior job. They cleaned everything up. I wouldn’t have even know that they had been here. They are very respectful they will work with you, and most of all you cannot go wrong with the Guardian company!!

We got our siding done a couple months ago and just recently decided to also go ahead with black Cericade on our roof as well! There is no doubt this has really elevated the look of our house and I am so happy with the results, but also with the quality of work! From Joe, to Cody, to the crew installing, everyone was extremely helpful and professional.
