We replace worn commercial flat roofs with durable, energy-efficient systems that protect your building and reduce downtime.
At Great Western Roofing, we handle TPO roof replacement for commercial and industrial buildings that need a tougher, more energy-efficient roofing system. If your current single-ply roof is failing, leaking, shrinking, pulling at the seams, or costing more and more to repair, a full replacement may be the smarter long-term move. We help property owners, facility managers, and general contractors replace worn-out roofing with a clean, dependable thermoplastic polyolefin (TPO) system built for performance.
TPO is one of the most popular commercial roofing materials for flat and low-slope roofs. It is known for strong seam performance, heat-welded installation, UV resistance, and reflective energy-saving properties. A properly installed TPO membrane can help lower roof surface temperatures, improve building efficiency, and give you a modern roofing system that is easier to maintain than many older roof types.
Not every roof can be saved with a repair or restoration. We usually recommend replacement when the roofing system has widespread damage or has reached the end of its service life. Common signs include:
We do not believe in pushing a replacement when a repair will do the job. Our team starts with a careful inspection so we can give you clear, honest guidance based on the roof condition, budget, and goals for the property.
Our process is built to protect your building, reduce downtime, and provide a roofing system that lasts. Scope may vary by property, but a typical TPO replacement project includes:
Every roof is different. We match the system design to the building use, roof traffic, exposure, drainage needs, and local climate demands here in Utah and the surrounding region.
We install commercial TPO systems in different configurations based on your building requirements. These may include:
Membrane thickness and assembly details can vary by project. We review the best options based on roof size, building use, code requirements, and budget. Our goal is to give you a roof system that performs well now and makes sense over the long term.
A new TPO roof can offer several practical benefits for commercial property owners:
For many facilities, replacing an older roof with TPO is not just about stopping leaks. It is about protecting inventory, equipment, tenants, staff, and operations inside the building.
Great Western Roofing focuses on commercial and industrial roofing. That matters when you are replacing a roof on an occupied building, warehouse, school, retail site, office, or large facility. We bring 20 years of experience as a Utah roofing contractor, and we understand how to plan around business operations, site access, safety needs, weather windows, and long-term roof performance.
Our team has worked on major projects including Walmarts in Utah and Wyoming, Daniels Canyon Elementary, and other demanding commercial properties. We are also Owens & Corning Certified Master Applicators, and we stand behind our workmanship. When we replace a roof, we do it with attention to detail because small mistakes on a commercial roof can turn into big problems later.
We keep the process straightforward and well managed from start to finish:
Clear communication is a big part of our service. We want you to know what is happening on your project and feel confident in the work being done.
If your flat or low-slope roof is beyond repair, we are ready to help you make the right replacement decision. A professionally installed TPO system can protect your building, improve efficiency, and reduce future roofing headaches.
Contact Great Western Roofing today to schedule a TPO roof inspection and replacement estimate. We will take a close look at your roof, explain your options clearly, and help you move forward with a commercial roofing system you can trust.
We start with a full on-site inspection of your existing TPO roofing system, insulation, seams, flashing, and drainage to find leaks, moisture issues, and failure points. Then we give you a clear scope, budget, and schedule so you know exactly what your commercial roof replacement involves.
Before work begins, we coordinate safety, material staging, and access to limit disruption to your building operations. Our crew removes damaged membrane sections, checks the roof deck, replaces compromised insulation, and prepares a solid substrate for a long-lasting single-ply roofing system.
We install your new TPO membrane with attention to welds, edge metal, penetrations, and rooftop details that often cause future leaks if missed. After installation, we complete a final inspection, clean the site, and walk you through the finished roof so you can feel confident in the workmanship and warranty.

"Dallin was the contractor from this company who helped me with my project. He is super knowledgeable, professional, and quick in his work and he goes above and beyond to make sure everything is done right. The pricing and quality were great. I will definitely work with him in future projects."
"Great to work with!"
"Bryce was so great to work with! He was quick to respond, quick to get to our house and determine what was wrong and then he quickly made the repair. We highly recommend Great Western Roofing!"
"We called GWR after discovering a leak because they installed our roof in 2007. Dallin responded promptly and came later that afternoon to check out the problem. He was able to fix the issue on the spot... despite having to climb through snow! He invited us to call him in the spring to check for any other issues. I highly recommend Great Western Roofing for any roofing needs."
"I am the Director of Facilities for a nonprofit, six building campus in Salt Lake City. GWR won a public bid on a City grant project to reroof a large apartment building we have on campus. They were incredibly efficient and easy to work with. They did a great job on upgrading our shingles, gutters, and roof ventilation system. I saw firsthand the little details they took to time to ensure were done that can mean the difference between leaks and structural damage over time or not. Dallin and Adam were awesome to work with and extremely friendly and professional. Dallin has since helped us with a few other minor roofing issues across campus and have been my go-to company for roofing/decking needs here. I highly recommend them."
