About Capstone Roofing
A Family-Owned Local Company
Nathan DuCharme’s father founded Capstone Roofing in 1989. Nathan learned the business from the ground up and took over the company in 1999. Today, we have nearly 30 years of experience providing quality roofing services in Sonoma, Marin, and Napa Counties, serving clients in Santa Rosa, San Rafael, Napa, and beyond. Nathan and his wife, Rhonda (who heads the administrative office), remain committed to our family values of honest, reliable, and fast service, backed by warranties and the Diamond Certified Performance Guarantee. Our goal is to provide 100 percent satisfaction on every job. Our clients are our number one priority, and it shows in every interaction. The best proof is that most of our clients come through referrals—former customers who are glad to recommend us to their friends and family.
About Our Quality Roofing Installation Services
We like surprising our clients by making it seem like we were never there. They come home from work and we’re already gone—except they have a brand-new roof! Our skills and experience let us complete most roofing jobs from start to finish in one day. That means less hassle and stress for our clients; there’s no worrying about weather, no need to tarp over or cover the roof, and no reason to worry about your home being open to the elements. Our strict attention to detail and quality control mean that your job will be done right the first time. We create a detailed plan for every job. The crew manager gets thorough written specifications for every project before it begins, and each crew member works their hardest to accomplish our clients’ goals.
About Our Skilled and Dedicated Crew
Our employees are skilled roofers with the training and experience needed to do the job right the first time. Most have been with our company for years, so they work as a team and provide the best quality roofing services for our clients. Our employee base of 30 experienced roofers also means that we can tailor our crew size to the job. Larger jobs are no problem—we simply bring a bigger crew to get the work done on time. Our employees are courteous and friendly. We treat our customers the way we want to be treated, and we emphasize clear communication and honesty.
Caring and Helpful Office Staff
Capstone Roofing has a courteous full-time office staff that is always on hand and ready to assist you in every way possible. When you call us, you won’t have to deal with voicemail or an answering service—you’ll talk to somebody right away. To set up a free estimate or roofing consultation with one of our experts, contact our administrative assistant, Carolyn, at (707) 575-3577.
About Our Family
Nathan and Rhonda DuCharme live and work in Sonoma County. They have been married for more than 20 years and have six children. Of course, as small business owners, Capstone Roofing is, in some ways, the seventh! Nathan works in the field while Rhonda heads the administrative office, so clients get the benefit of working with the company owners on every job.

I loved Capstone Roofing and would recommend them to anyone. They are the best contractor I hired in 26 years of owning this house. The owner is very involved in Windsor as well personally with his kids. They did my whole roof from 6:30 am to 3pm in one day for a good price and left the place spotless outside. They also installed 3 solar tubes for me which I highly recommend for dimly lit houses.

They did an excellent job. Their estimate was fair and competitive. They re-roofed the whole house in one day. I recommend Capstone to all my friends.
