Drones Take Our Roofing Services to New Heights
Douglass Colony takes care of every building as if it were our own. With our unmatched blend of people, history, innovation, and quality we take on the jobs that others won’t. From re-roofing and waterproofing that can give a building new life to commercial roof service, maintenance, and fast repairs that can save building owners big money, Douglass Colony delivers nothing but the finest results — every time.
Harnessing our drone capabilities, we can provide you with a bird’s eye view of your building. Using drone technology, we can easily pinpoint potential risks before they become a problem without needing the manpower to safely get up on your roof and inspect it ourselves.
Check out this video that shows some of our capabilities and how we put our drones to work for you.

Testimonials
I can say without hesitation Douglass Colony performed an outstanding job to even go as far to say one of the best I’ve ever been a part of.
Douglass Colony did a wonderful job working with our customer service department to get material to the project site in the very busy downtown of Denver… The final appearance of the project was outstanding.
I appreciate the push to get [the work at YVMC] done quickly and efficiently, and the canopy work looks great. I appreciate your help in that successful schedule. Thanks for the hard work to get this phase successfully completed
