Residential and Commercial Window Replacement

Keep your home or business looking good and energy-efficient with updated windows.
Without windows, spending time inside would leave us with little ability to enjoy the outside world while safe from the elements. Windows are an important part of a home or business, as they are one of the first things noticed when inside. If your windows are falling apart or don’t fit your home or office, the whole structure will be impacted. Updated, functional windows are essential to making an indoor space comfortable, keeping the warm/cool air in and everything else out.

Rocky Mountain Roofing & Exteriors, made updating my house interior seamless and enjoyable! I was guided in the choosing of paint color and the whole project was discussed in full detail. The preparation was immaculate and all attention was paid to keeping everything clean and spotless.We didn't expect the quick turn around on such a large space and on top of that they did a fantastic job. It's evident that their team has experience and works towards perfection. Would absolutely use them over and over again.

Summer 2022. This is the second review I am doing for Rocky Mountain Roofing & Exteriors. This summer my house suffered a lot of storm damage again. I needed to have the roof replaced, gutters replaced, some wood trim replaced, some windows replaced, and get the house painted.They, especially Ben, took care of everything. They showed up to my house quickly to do the inspections. They took care of contacting my insurance company and got everything going with them. All the work was done in a timely manner and every crew that came out were professional and did quality work. The communication throughout the whole process was great. I was never left wondering or having to constantly contact them.I would definitely use this company again for future work.Summer 2021It was a pleasure to work with Rocky Mountain Roofing & Exteriors. Everything from the initial inspection, to the installation, to the final inspection was a breeze. Ben kept in constant communication and made everything go smoothly. He also handled everything with the Insurance company. All I really had to do was sit back and relax. The roof looks great.

Heath and his team have been exceptional since day 1. We have never worked with a contractor before concerning hail damage as homeowners and we can tell you this has been a great first time experience.We had some issues with the insurance company and Heath went to bat for us getting us what we deserved. We had new gutters, roof and paint done to our home, along with staining our fence and pergola and it was all done with great professionalism.We plan on using them for future work on our home.Thank you Rocky Mountain Roofing & Exteriors!

I just had my roof replaced by Rocky Mountain Roofing & Exteriors. They did a great job in every aspect of their work. I am very pleased with the final results from the past three days and I will be using them again soon to replace my gutters.

I hired Rocky Mountain Roofing & Exteriors to paint my home after getting bids from several other companies. They were professional, thorough, and went above and beyond to ensure all details were addressed. They also installed some new shutters that look great. They were even flexible when I needed to move dates and times around. I highly recommend them for painting services!
