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.

Roofing and Shingle Repairs

Don’t wait to get professional help for your roof. As soon as you notice damage or issues, give us a call. Our residential roofing contractors Billings will come out for a thorough repair. We’ll look at your flashing, shingles, and sections of roof that have fallen into disrepair. Your roof can be damaged by a variety of factors, including normal wear and tear, heavy snowfalls, and ice dams. These issues won’t sort themselves out on their own and could lead to a premature replacement of your roof.

Choose the Right Shingles

Whether you’re looking for durability or style, there are plenty of shingles on the market to choose from. Ask our residential roofing contractors Billings about our:

Synthetic Tiles: Synthetic tiles are designed to look like natural materials. But unlike authentic slate and wood, modern synthetic tiles usually come at a lower price point and can also reduce your roof maintenance.

Metal Roofing: Metal roofing enhances the unique style of your property and is known for its energy efficiency and durability. They’re sleek, sophisticated, and hold up against snowfalls and inclement temperatures.

Asphalt Shingles: Asphalt shingles are always in demand as a cost-effective, durable option. They also come in a range of styles and colors that enhance your property’s signature style for their affordability, durability, and versatility.

Low Slope Roofing: While they are typically more suitable for commercial properties, low slope roofs are also suitable for residential use. Low slope roofs are renowned for their waterproofing properties and durability, which effectively prevent leaks and damage.

Repair Your Flashing

Although your roof’s flashing is durable, thin, and resistant to damage, it can still sustain damage. Flashing is usually found around your chimney, windows, roofs, and other areas, and an airtight seal is crucial. If your flashing become torn or broken, it could potentially lead to mold growth and structural damage.
