We're very happy with them. When we had an issue, they came right back to fix it. They actually left us a sample of spray paint for touch-ups on the metal bars, so that when we needed it, we didn't have to buy more spray paint.

When we needed help with another roofing project, which was something they didn't necessarily do because it was too small of a job, they referred us to somebody else.

It was so easy to work with them. They were very reasonable with their estimate, and they weren't pushy. They gave me the pricing of each item exactly. They got it done very quickly, they were pretty straightforward, and I had no issues with them. It was awesome. I would totally recommend them to anybody.

I would say their options and their quality of work are amazing. My roof is not a standard roof. It's more of an open beam ceiling type roof. They were very knowledgeable of our house, and they were able to give me several options regarding the roof. It turned out beautifully. The clean-up was taken care of, and everything was perfect, like they've been doing it for years.

  • Protecting Your Roof and Gutters with Tree Maintenance

    by Alex Oceguera of
    Cosmos Roofing

    MOUNTAIN VIEW — If you have trees around your home, it’s important to be diligent about tree maintenance—after all, your roof may depend on it. When fallen tree leaves, needles and branches aren’t routinely cleaned off of your roof, they’ll accumulate in your valleys, skylights and gutters, which can cause water blockages when it rains. Have a maintenance professional, landscaper or roofer go up on your roof and remove tree debris on a regular basis. This will extend the lifespan of your roof and gutters and prevent expensive damage... Read moreRead less

I like that he is a local roofer, a family-owned small business. I like to use local businesses and give back to the community. They are hands-on, even his dad was out working.

They communicated, they were prompt, they did what they said they were going to do, and they had fair prices.

They do quality work, on time. They're very competitively priced and very easy to engage with throughout the process.

What I liked best was that they were very, very flexible. They made sure they were able to complete the project while working alongside a contractor who was doing another job at the same time. They worked so incredibly well with each other where it's normally a stumbling block. The contractor that we used recommends them to people as well. They exceeded our expectations.

I would say that they were very professional and courteous. They came on time, they left the place really clean, and they gave us expertise, in terms of the structural beams that were holding up my roof. I needed to have that done before the roof was put on, because 2 of the 4 corners were sagging, and they were very helpful in that regard.
