About Us
A letter from owner Doug Moncure to our customers:
When I started M&M Roofing in 1983, I wanted to create a company that was focused on giving every homeowner peace of mind. For over 40 years, that dedication hasn’t changed and became our tagline—”For Peace of Mind.”
Our three-part plan ensures that our clients experience as little stress as possible:
- The estimate: We send well-trained professionals to perform a free consultation and inspection.
- The home improvement: Whoever performs your inspection will also be your lead project manager,
overseeing your job to make sure that you get exactly what you expect.
- The phone call: After your job is complete, I will personally call to check in with you. If you’re not satisfied,
you have my word that we will fix it.

I recently had the pleasure of working with M&M for siding work on my house, and I must say, the experience exceeded all my expectations. From the get-go, the level of customer service was simply outstanding. A special shoutout to Sam, our representative, who was not only professional and knowledgeable but also incredibly attentive to our needs.
Sam went above and beyond to ensure that all our questions were answered, and our concerns addressed, making the entire process smooth and stress-free.

We just had our roof replaced by M&M Roofing in Clearlake and were very pleased with their work. Michael McCollom did a great job of explaining everything to us beforehand, including discussing options and plans, the pricing and scope was very fair and reasonable. Once we signed the contract for the work, he communicated with us promptly about dates and expectations. The crew showed up and they were extremely fast and efficient. The roof looks great, and we couldn't be happier. We highly recommend M&M Roofing Siding & Windows.

We had M&M come out to repair a couple of leaks in our covered patio. Greg was super helpful in diagnosing the issues, providing lots of information on how best to make the repairs and options for what we needed.

The work was completed in one day and Greg came out to make sure the crew was doing everything the way he wanted. The whole process was really great. Very professional from start to finish. Thanks M&M.
