About Derek Cook's Roofing Specialists

Hello, thank you for taking the time to read DC’s history. I started this company in 1998. The company has done better than I ever imagined. It is amazing how powerful word of mouth can be. It puts a smile on my face when I hear some of my client's reviews. “There is only one company you should use and that is DC Construction”. I have painstakingly developed a formula to provide the ultimate experience to my clients. We take pride in what we do, we treat the client's property as if it was our own. We keep an impeccably clean jobsite, and never leave a mess. The men who work for me share the same pride and attitude in how they perform in and out of work. Through the economic down turn of the last few years, my company has grown. That is a testament of the quality product that DC Construction provides its clients. We look forward working with you!

"I have had DC Construction do roofs on two of my homes.  Derek and his team are always punctual, professional and considerate.  Derek's availability via phone and email always made scheduling and connecting easy.  I would highly recommend Derek to anyone."

 - Tim, Bedford, NH

"Derek and DC Construction installed new windows and did a great job.  Not only did they do the work with little disruption, they made sure everything was cleaned up before they left.  DC Construction also has a solid quote where the other companies will quote low and add "overages" once they get the job.  I will us DC Construction for all my future projects."
