Our Team

We have been in business for over 30 years and have over 200 years of employee experience in roofing and construction. We specialize in customer service, and stand behind our product—we are second to none. There is no job that is to big or to small, and even if you might think its impossible, it will just take Sound Building Supply a little longer!
