Customer Reviews
Very professional and easy to work with. We had a complicated job and Los Gatos Roofing did a great jog helping us through it. Thank you team and Craig!
outstanding experience from beginning to end! we didn’t worry about a thing. For such a major project that’s saying a lot. We went over our options carefully, the crew was wonderful, and the roof looks great! it was always easy to get a hold of our project manager who was extremely helpful during the whole process.
Los Gatos Roofing did an amazing job replacing our roof. Our project manager, Dave Burt, was very helpful throughout the process from the first meeting until the day of completion. The work crew was respectful of our property and they finished the job ahead of schedule. The whole thing was very organized. Highly recommend Los Gatos Roofing.
33 years ago Los Gatos Roofing put my roof on, and did a great job, after 33 years it was time for a new roof, I called Los Gatos Roofing and my name and address was still in their database 😎. Dave came out and we scheduled for our new roof, why change companies when they did a great job 33 years ago and I have no regrets, another great job, the three brothers who did our roof were outstanding, Dave was so professional and personal the follow up and clean up was great.

Frequently Asked Questions
We have been part of the Bay Area community since 1905 and have been replacing roofs in San Jose since 1978, and the Radonich family has built this company on one principle: do the work right and stand behind it completely. We hold the Diamond Certified Award, the Angi Super Service Award, and elite certifications from Owens Corning, CertainTeed, and Malarkey, and we have earned over 400 five-star reviews across Google and Yelp. We never use subcontractors on any project, which means the team that shows up at your home is our team, trained to our standards, every single time.
We install a full range of residential roofing systems including fiberglass asphalt composition shingles, standing seam metal roofing, concrete and clay tile, cedar shakes and shingles, and green roofing products. Whatever material fits your home's architecture, your energy goals, or your budget, we carry the certifications and experience to install it correctly and back it with the strongest manufacturer warranties available. Our team will walk you through the options during a free in-home estimate so you can make a fully informed decision.
Never. Every member of the crew that arrives at your home is a direct Los Gatos Roofing employee, and that applies to both roofing and gutter installation. We believe quality control starts with owning the work from start to finish, and using subcontractors introduces variables we are not willing to accept. This is one of the most important questions you can ask any roofing contractor, and our answer has never changed in over four decades of serving the South Bay.
If you are seeing water pooling near your foundation, staining on your exterior walls, erosion in your landscaping, or gutters that are sagging, pulling away, or visibly clogged after every rain, it is worth having us take a look. We can assess whether a repair is all you need or whether a full replacement makes more sense, and we will give you an honest recommendation either way. Our gutters are fabricated on location and custom-fit to your roofline, and we repair systems we did not originally install as well.
For most Bay Area homeowners, yes, it is one of the highest-return home improvements available. According to Energy Star, a properly insulated attic can reduce heating and cooling costs by up to 20% per year, and homes with insufficient insulation can lose up to 40% of their conditioned air through the attic alone. Our free inspection takes a quick look at your current insulation levels, and if you decide to move forward, the full installation using our Owens Corning AttiCat blown-in system is typically completed in under two hours with minimal mess and no settling over time.
