Commercial Roofing Contractor in Minneapolis, MN

A variety of roof coating systems built to protect your building and your bottom line.

Thompson Exteriors has serviced commercial roofs across the Twin Cities for over 30 years, from retail strip malls to warehouses and multi-family buildings. We help property owners extend roof life and avoid unnecessary full replacements, with owner Peter Thompson personally overseeing every commercial project.

What Happens When a Commercial Roof Is Neglected​

A failing commercial roof puts more than your building at risk.

Interior Damage

Ponding water and membrane seams that have failed let water into insulation, ceiling tiles, and inventory below, often before leaks are visible from inside the building.

Costly Downtime

Emergency repairs on a failing membrane roof cost more and take longer than planned maintenance, and they can force you to close areas of your building during the work.

Lost Energy Efficiency

An aging, non-reflective roof surface drives up cooling costs in the summer, while gaps in insulation and membrane seams let conditioned air escape year-round.

What to Expect From Your Commercial Roofing Project

From first call to final walkthrough, here's how we work.

We Assess Your Roof System

We inspect your membrane, flashing, drainage, and insulation to determine your roof's actual condition and remaining lifespan, checking for ponding water, seam failures, and coating candidacy. We document findings with photos and a written condition report.

We Scope Your Options

We present a clear scope covering repair, silicone coating, or full replacement, with cost and lifespan tradeoffs for each option, so you can make a decision based on your budget and building timeline, not just the lowest bid.

You Choose Your System

We walk you through TPO, EPDM, single membrane, and GACO silicone coating options, including warranty terms and expected service life, so you can choose the system that fits your building and budget.

We Complete the Work

Our crew executes the project on a schedule built around your operations, with daily cleanup and site safety measures appropriate for an active business. Peter checks the finished work before we

FAQs

Some of our most Frequently Asked Questions.

Do I need a full roof replacement, or can my commercial roof be repaired?

It depends on your roof's age, condition, and how much of the membrane is still sound. Many aging TPO, EPDM, and modified bitumen roofs are good candidates for a silicone coating system instead of a full tear-off, which can extend the roof's life by 10 to 15 years at a fraction of the cost. We'll give you a straightforward recommendation after a full assessment, not just a sales pitch for the most expensive option.

What is silicone roof coating and how does it work?

Silicone roof coating is a seamless, highly elastic, waterproof membrane applied directly over your existing roof surface, sealing seams and minor damage while adding reflective UV protection. It's especially effective on roofs with ponding water, since it resists degradation from standing water better than most other coating materials. As Minnesota's only certified GACO installer, we can offer this option when a full replacement isn't necessary yet.

What's the difference between TPO and EPDM roofing?

TPO is a reflective, heat-welded membrane that performs well in energy efficiency and is popular for retail, office, and industrial buildings. EPDM is a synthetic rubber membrane with a long track record of durability in extreme temperatures and strong resistance to hail. We'll help you weigh cost, energy performance, and durability based on your building type and budget.

How long does a commercial roofing project take?

Timeline depends on your building's size, the system you choose, and whether the work is a coating application, targeted repair, or full replacement. Coating projects are typically faster and less disruptive than tear-offs. We'll give you a specific timeline and phasing plan once we've assessed your roof, especially important if your building needs to stay operational during the work.

Can commercial roofing work be done without shutting down my business?

In most cases, yes. We plan commercial projects around your operating hours and can phase work across sections of larger roofs to minimize disruption to tenants and customers. We'll walk through scheduling options with you during the scoping phase so the project fits your business, not the other way around.

What warranty comes with commercial roofing work?

Warranty coverage depends on the system and manufacturer, and certified installation is required to keep those warranties valid. As a certified GACO installer, our coating work qualifies for full manufacturer warranty protection, and we'll walk you through specific terms for TPO and EPDM systems during your assessment.

They did two roofs for us after a bad hailstorm here in Minneapolis. For one of these they replaced a skylight and we were very happy with the product they suggested. This firm is especially skilled at doing roofs on older Minneapolis houses. (Both of our properties are over 100 years old.) It is clear they have a lot of experience working in the inner city.

I got new siding and a new roof by Thompson last July, with final completion of a remaining task the following August. The workmanship was excellent, with detailed attention on the siding and trim. Peter and crew took extra time to make sure the porch (which was sinking since it was built in 1919) had stable footings, and they jacked it up to make it level with the house to complete the siding. It meant the doors and windows were now plum, whereas before they were tilted, hence the remaining task to fill in gaps of siding on the interior porch and at the door (all were unexpected to the original plan). I had some frustration with nailing timelines down and follow up: I had a limited window in which the work needed to happen (6 weeks) because I was otherwise away and I wanted to be there to oversee the work. The roof and siding were completed the morning I was leaving town, which was stressful, but it got done. In the end I would use them again because quality workmanship is more important to me than project management (and more rare), but know that they are less strong at organization and timelines/appointments. I experienced more on the fly follow up, texts and drop by questions (usually on evenings or Saturday) to get remaining insurance estimates, measurements, colors, payment etc. He seemed totally swamped, but I think this is just the way Peter rolls.

Great experience with storm damage roof replacement, looking forward to siding replacement. Peter came to the house to review the job & provided shingle samples including higher spec level that we would have had to pay additional cost above insurance settlement. No pressure to go with the higher spec/cost option, which we declined. Lead time quoted at the house was 3-4 weeks and the roof was replaced 4 weeks later. Building permit was pulled before starting the job. Roofing crew completed the house & garage in one day: tear-off, new shingles, thorough clean-up of yard, and waste trailer hauled away. Peter was personally on-site multiple times during the day to oversee the job. Overall wouldn't hesitate to hire them again, they lived up to my expectations based on a doing good work on a small

Thompson Exteriors quote included pulling a permit and removal and reinstall of the gutters. The permit was never pulled. The gutters were never removed so they are full of debris and nails that my dogs/kids could get hurt on. Some shingles weren’t nailed down properly. They damaged a piece of siding during the project and the dryer vent has been blocked since the roof was installed. I have contacted Peter to make repairs and pull the permit so that I can make the final payment but he has been ghosting me. So beware.

Peter and his crew did a great job reroofing our house in 2020. They do quality work - it still looks brand new! A portion of our home had a flat roof that we wanted to add a gable to. Peter was able to understand what we were looking for and make recommendations on the design. We ended up with a gable that was constructed to blend with the existing architecture and finishes seamlessly. We plan to use them for additional exterior work in the future.

Overall, a really good roofing job from Thompson Exteriors. The new shingles look nice and professional, and the extra work to reinforce my old house’s sagging eve issue was worth it. Once the work got started, they were consistent and professional every day that they showed up. Job didn’t take relatively long and workers were there consistently every day until to the work was finished. One constructive piece of feedback: They need project managers. At times it was hard to nail down the exact start date, and felt like it was pushed several times. This may have been due to too many jobs on the plate of my point-of-contact, or just simply the lack of a project manager.

The owner was responsive when I first reached out. He showed up at the wrong time (about an hour early) for our original meeting but thankfully my father in law was there to discuss the project. The owner declined my job stating “he was too busy” and it would be too complicated. I had explained before our meeting that I would need a custom fit door and he said no problem as he has done new doors in my neighborhood before. However, he seemed caught off guard by the fact that the door needing to be replaced was not a standard size as the home was built in 1912. I appreciate his honesty and time; however, using the words “too busy” just seemed unprofessional in my opinion.

Peter and his roofing team just did a great job on our house. They were friendly and worked hard to complete the project before it rained. They did a good job cleaning up and left very little for me to find. His estimate was spot on and was upfront about all costs to the project. He also took the time to come to our house to explain the quote, which no other company attempted or followed up. The final bill was under all of his competitors and the quality of work was excellent. I would highly recommend using his company or getting a quote from him with all the other companies you are going to ask.

We worked with Thompson Exteriors to do a major home exterior project consisting of new siding, trim, roof, flat roof finishing, painting of a detached garage and teardown of an old chimney and replacing with a new chimney in 2019. We are very happy with the end result and with the communication that took place along the way. A brutal hail storm led to us requiring another new roof in 2024. Thompson Exteriors did a great job of working with is to have our replacement roof done quickly and well. Our 100+ year old home looks great and recommend Thompson Exteriors.
