The Bold North Difference
Commercial roofing is where most contractors stop being honest. Bids come in low, subcontractors get hired, oversight disappears, and property managers are left with roofing problems that should have been caught during installation. Bold North Exteriors approaches commercial work the same way we approach residential — Jon is involved in every job, we use materials we stand behind, and we're accountable for the result long after the invoice is paid. If that sounds like what you're looking for in a commercial contractor, we'd like to talk.
The commercial roofing market in Minnesota is dominated by flat and low-slope systems — primarily TPO and EPDM membrane roofing — because most commercial buildings have rooflines designed for drainage rather than pitch. These systems perform well in Minnesota's climate when installed correctly: TPO's heat-welded seams create a monolithic waterproof surface that handles freeze-thaw expansion better than taped alternatives, and EPDM's rubber membrane remains flexible at temperatures down to -40°F. We install and repair both, and we explain the differences honestly so you can make the right call for your building.
Commercial roofing projects range from small retail building repairs to full membrane replacements on larger structures. We work with property managers, business owners, HOAs with commercial buildings, and property investors across the south metro. Every project starts with a free inspection and written proposal that itemizes materials, labor, scope, and timeline. No vague estimates, no change orders that weren't discussed upfront.
Options we offer
Commercial Roofing Systems
TPO Membrane Roofing
Thermoplastic polyolefin single-ply membrane — Minnesota's most common commercial flat roof system. Heat-welded seams create a monolithic waterproof surface. UV-resistant, energy-efficient, and handles freeze-thaw cycling well. Cost range: $7–$13 per square foot installed.
EPDM Rubber Roofing
Ethylene propylene diene monomer — a flexible rubber membrane that remains pliable at extreme cold temperatures. Excellent freeze resistance, 20–30 year lifespan with proper maintenance. Generally 20% more affordable than TPO. Best for buildings where energy efficiency is less critical.
Commercial Asphalt & Modified Bitumen
For commercial buildings with pitched rooflines. Modified bitumen provides multi-layer protection with strong puncture resistance — often used where foot traffic around rooftop mechanical equipment is frequent.
Commercial Roof Repair & Maintenance
Seam re-welding, membrane patching, flashing repair, and drain clearing for existing commercial systems. Preventive maintenance programs available for property managers wanting scheduled inspections and documentation.

Don't just take our word for it - hear from real Minnesota homeowners who've experienced our no- pressure, transparent estimate process.
It was fantastic working with Jon and Bold North Exteriors. We had just a small job for him to do and he took the time to find the exact color match and made sure it was perfect. Communication was great and would highly recommend him anytime. Whenever we need roofing done in the future, Jon is the guy we will call.
Jen Wood
They did a good job with installing two new exterior doors. Good communication, on schedule, cleaned up properly afterward.

Jon from Bold North Exteriors delivered on a tricky project for us and was top notch! I would not hesitate to use him for future needs or to recommend him to anyone.

Common Questions
Commercial Roofing FAQ
How much does commercial roofing cost in Minnesota?
Commercial roofing costs depend heavily on system type, building size, and roof condition. TPO installation in Minnesota typically runs $7–$13 per square foot for standard projects, with larger or more complex roofs at the higher end. EPDM is generally 15–25% less expensive. We provide detailed written proposals with line-item pricing after a free inspection so you can plan your budget accurately.
What is the difference between TPO and EPDM roofing?
Both are single-ply flat roof membrane systems. TPO uses heat-welded seams for a monolithic waterproof surface and has strong UV and energy efficiency performance. EPDM is a rubber membrane with excellent cold-temperature flexibility and generally lower upfront cost. The right choice depends on your building's specific situation — we explain both honestly and recommend based on what actually makes sense for your property.
How often does a commercial flat roof need maintenance?
Commercial flat roofs should be inspected twice annually — ideally in spring after freeze-thaw season and in fall before winter — plus after any significant storm event. Regular inspection catches seam separation, membrane punctures, and drainage issues early, when they're inexpensive to address. We offer maintenance programs for property managers wanting scheduled inspections and written documentation.
Do you handle commercial storm damage insurance claims?
Yes — the claim documentation process for commercial properties is similar to residential, though the scope is often larger and the carrier relationship more complex. We inspect, document, attend the adjuster appointment, and provide detailed supplemental documentation to support a complete claim approval.
