Drivers are awful. 0/10 your drivers shouldn't flip the bird to people in traffic in a company vehicle.

This company is horrible, rude, inconsiderate, and unprofessional. I work for a small local Colorado company that is in a strip mall next to King Soopers. Douglas Colony did a roofing job for King Soopers however they never notified us that they were going to block one of our major business accesses for several weeks. When trying kindly to work out a solution they told us that our employees safety, our inability to get deliveries, the loss of business, and our inability to access our pickup and drop off location did not matter to them.
There roofing project was more important then the safety of our employees. Trying to get a hold of their site superintendent is impossible, after leaving multiple messages I never did receive a call back. Very unprofessional I would not suggest using this company safety issues alone will keep me from ever using this company. The disrespect for small business owners is another. Hire local and skip this big money hungry, unsafe roofing company.

Your employee who was driving a company truck on 120th coming up to 287 at 3 this afternoon just a few minutes ago he almost ran me off the road and proceeded to flip me off in your company van when he got into my lane and it was not safe you need to train your employees to drive safer before I come in and make a complaint to the police you are lucky that my car was not ruined by going off of the road a little

This company was good at the beginning then they run you thru the dirt and don't help to clean you up. No progress, they mess with your pay and if you track your hours they don't take them into account, misuse of power, racist, discriminative, name calling, and the office won't help because they know there company is this way from the beginning and there not going to change it, they will bluntly tell you off.
It would be in my best option to find yourself a more trust worthy company that will progress you along the way instead of not giving to cruds about you. Take this as you will but please keep reading reviews they will tell you exactly how this company acts.

What a real pleasure it was dealing with DOUGLAS/COLONY in all aspects of the construction process. From the initial concept presentation, pre-construction meeting and every step of the construction, they kept us informed of the timely process. I was very impressed with their focus on safety of their employees and the construction site. The Quality Control Inspection at the end proved to me that I picked the right company to replace our roof. It was a very refreshing experience. GEORGE MICHEL II, Vice President MMT, INC.
