It all started back in 2009. Two family friends, who were tired of contractors promising one thing and delivering another, came together to try something different. DNB Construction was formed with a focus of bringing quality work to every job. From the smallest roof repairs to the largest custom home builds, our experts will bring attention and care to your project. We are master installers of asphalt shingles, natural/synthetic slate, cedar shake and shingle, custom metal roofing, and TPO. With big investments in state-of-the-art equipment and continuing education of our employees, DNB is bringing cutting edge technology and craftsmanship together to our customer's projects. "No customer left unhappy" is our motto, and the driving force behind the rapid success of our company.
