Repair Your Commercial Roof

Our roofing experts work on all types of buildings, including low slope roofs. We can replace your entire roof or address those repairs that are keeping you from operating efficiently. Don’t let the damage get out of hand. Addressing the damage as soon as possible is your best chance at getting on top of the problem before it spirals into a costly fix.

Restore Your Commercial Roof

Do you have extensive damage but aren’t sure if you need a full replacement or can still fix your roof? You may need commercial roof restoration that addresses leaks, rips, repairs, and more. Our team can also safely remove growing ice dams and ready your roof to stand up against Montana’s harsh winters. We also prioritize quality and select durable materials that both protect your business and keep it looking incredible. Or, ask us about sustainable solutions that can potentially reduce your heating and cooling costs.

Safely Remove Ice Dams and Snow

Montana locals are no strangers to snow dams, ice, and snow that can build up on their roofs and cause damage. Your roof could face damage as the dam melts and refreezes bigger than ever before. Don’t wait for the ice to melt on its own or the damage may already be done. Instead, call our roofing experts for immediate help. We use advanced technology and equipment to melt and remove the dams safely. We’ll respond as quickly as possible and stop the damage in its tracks.

When the job is done right, you get a higher ROI out of your investment and have more peace of mind that your property is protected. If your roof is installed incorrectly, you could end up with water damage, mold, mildew, and structural damage that could pose grave issues for your commercial property.

I called Dennis General Contractor after identifying missing shingles on my roof. Within two days, Forest came out and not only evaluated my roof - he fixed it! He had a full schedule but managed to fit me in before the snow fell. I am incredibly grateful! He was amazing to work with - so responsive, detailed, and very reasonable prices!  highly recommend him and his company!

Offers free inspections with a roof report that highlights areas of concern. The inspector let me know I had life left in my roof when the other companies were trying to convince me to replace it right away. I appreciated her honesty and look forward to having it replaced with this company.

The whole experience from start to finish was incredible. I had called several outfits and only half even bothered to return my call. These guys came right out and discussed my options in plain, non high pressure fashion. It was a roof replacement for my pet boarding business so was important they be able to work around my schedule.
The crew was fantastic. So courteous, professional, clean and FAST! I expected to have a bit of cleanup to do after they left but they were so thorough.
The best part was dealing with Jasmyn. You are an absolute gem and I appreciate you greatly!

Dennis General Contractor replaced our roof shingles and did a fantastic job. The workmanship is of high quality and the crews were very skilled and professional. Because of an upcoming real estate transaction there was some urgency to the job, and they started and finished the work in a very timely manner. The quote for the work was detailed, accurate, and very reasonable. Their online portal system made contract signing and payment easy and provided transparency throughout the process. I highly recommend Dennis General Contractor for any roofing or other construction needs you might have.

After battling a leaking garage roof for years (!), I finally had it replaced by Dennis General Contractors. From start to finish, the team courteous, proactive, and professional. They are competitively priced and the service is off the charts. The crew had my roof done in less than three days and it makes my house look brand new. Now, I find myself still peeking into my garage on rainy days and being stoked that there are no waterfalls or puddles.
