TESTIMONIALS

Testimonials From
Our Valued Clients

Luis Avila from Guardian Roofing, Gutters, and Insulation is a chimney wizard. After the storms we experienced recently, our roof started leaking. Nathan and Johnny from Guardian (charming roof experts) thoroughly inspected the roof and attic and gave me the bad news that our chimney was the source of the leaks and would have to be rebuilt. It was our good fortune that Luis, and his partner Adalberto, were assigned the job. Their work ethic is exemplary, their attention to detail and craftsmanship superb, communication was great, and clean up was done completely. Luis’s expertise has left me with the peace of mind that all leaks are fixed and I have a beautiful chimney too! Phase 2 of the job will be gutter cleaning and moss abatement, and I know my roof will be good to go for years to come. Guardian Roofing is the company to call if you want the job done by experienced professionals who take pride in their work!

Hopefully, I picked the correct installation technician ("Gabe - 20ish young man w/blondish hair). He was an excellent tech. Although he was accompanied by another technician during the initial tear down & install of my new "K-Guard" gutter system (I think his name was Tim & possibly the "lead"), Gabe seemed to be mainly responsible for most of the sheet metal work (down spouts, catch traps, end caps,etc.). They were both extremely efficient during the install. Because they had a problem with the machine that extrudes the gutters, they were not able to finish approximately 10 ft of gutter in the correct color. Knowing this in advance, they came prepared. They brought enough linear footage in another color to complete the job and protect my home until we could schedule another time for them to return and complete the job. Gabe returned and finished the install with the correct color on my schedule, as I was recovering from surgery. My home has what I would call an unconventional patio roof installation where the main roof gutter runs under my patio. With extremely heavy rain, some (not most) water may slightly overflow the K-Guard "hood" and collect as droplets on the underside of the gutters. Because I required the underside of my patio to be completely dry for storage, I needed a solution for this problem. I called Joe in Guardian Operations for Oregon about the problem and he promptly scheduled Gabe to come back to help. The solution was to remove the portion of the hood under my patio so the gutter could collect ALL of the water from the main roof w/o any overflow. Problem solved! Needless to say, I am extremely pleased with Guardian! Starting with my interactions with my salesman, Grant Lucarelli (professional, courteous and respectful of my needs), the operations staff (scheduling and problem solving) and last but by no means least the expertise and professionalism of their installation technicians (care for my home and excellent cleanup), specifically Gabe! After finishing the job, Guardian's Quality Assurance person, Emory, came over to make sure I was satisfied with their work and exhibited the same exceptional qualities as the rest of the Guardian professionals. Based upon my experience with Guardian, I can most highly recommend them for your gutter replacement and/or repairs. I will be using them again for my backyard shed's gutter replacement this Spring 2026.
