Types of Commercial Roofs We Install
We install a variety of high-performance commercial roofing systems built for durability and energy efficiency.
EPDM Roofing
EPDM (Ethylene Propylene Diene Monomer) is a cost-effective rubber membrane ideal for flat and low-slope roofs. It offers excellent UV resistance and performs well in cold climates, making it a smart choice for Great Falls businesses.
PVC Roofing
PVC (Polyvinyl Chloride) roofing is known for its long lifespan, chemical resistance, and strong waterproofing capabilities. It’s ideal for restaurants or businesses that deal with grease, oils, or harsh runoff.
TPO Roofing
TPO (Thermoplastic Olefin) is an affordable, reflective, and energy-efficient membrane that’s perfect for businesses looking to reduce cooling costs. It’s easy to install and maintain, with great performance in a range of weather conditions.
Roof Coatings
Roof coatings add an extra layer of protection to any roofing project so that your roof’s integrity is secure. They can also be used on older roofs that are becoming less effective against the climate. Rolled or sprayed roof coatings are a smart way to make sure your roof is and stays sealed year after year. Moreover, if the roof does start to wear thin, add another coat, and you’ll be ready for the next decade of wear and tear.
Flat Roofing
Flat roofing is popular in many commercial buildings due to the great protection and minimal maintenance they offer. Because flat roofs have almost no slope, a proper installation is required to avoid any future problems. We’ll be happy to walk you through your options to see whether or not a flat roof is right for your building, as well as how to best maintain your flat roof going forward.

Commercial Roofing FAQs

Highly Recommended – Honest & Professional
A-1 Contractors, Inc. truly saved the day! After another company installed a new roof that soon developed … More problems, the original installer refused to come back and look at it. A-1 was willing to come out, perform a thorough inspection, and provide professional insight. They were incredibly understanding, helpful, and highly skilled. They restored my trust in quality contracting. I cannot recommend them highly enough for their expertise and integrity. - 100% recommend A1 to do your roof. Insurance paperwork was a nightmare but their estimator Chad bent over backwards to help figure ot out and straighten … More it out for me and the Insurance. Roof of garage and house were done in 1 day and looked like thery were never there on the clean up. Awesome company.
- They are amazing! My mother needed a last minute replacement on her roof for the sale of the house. Within 24 hours they had the estimate back to us and … More the job scheduled. They did everything they had to so they could squeeze us in last minute. They job was done within two days! We have had roofs replaced before and usually find nails and wood all over the yard after. I couldnt believe how clean the yard was after! They really came through for us in a critical moment. We appreciate them and their professionalism so much!

cleanup. Thank You , Danny and Crew
