Commercial Roofing in Billings, MT TPO, EPDM & Flat Roof Systems
Flat and low-slope roofing for businesses, multi-family properties, and pole buildings across south-central Montana. TPO, EPDM, and flat-roof repair — installed and serviced by our own employee crews. You get a real schedule, honest scope, and warranty paperwork in writing.
Flat & Low-Slope Systems Built for Montana Weather
Commercial and flat roofs are a different animal than a pitched shingle roof. Standing water, seam welds, membrane thickness, and drainage details are what make or break the roof — not just the material on top. We install and service TPO and EPDM membrane systems, and we handle flat-roof repair on existing buildings when a full replacement isn’t the right call yet.
TPO is a heat-welded, reflective single-ply membrane that shrugs off Montana sun and holds its seams for decades. EPDM is a proven rubber membrane that handles temperature swings and is easy to repair down the road. For flat-roof leaks on an existing building, we diagnose the actual failure point — a bad seam, a flashing detail at a curb, a clogged drain — and fix that, rather than tearing off a roof that has life left in it. Every commercial project runs with our own employee crews, and the owner walks the roof before we write a number.

Certified Crews, Honest Scope, Warranty in Writing
A commercial roof is a business decision as much as a building one. Two things separate a good commercial install from a bad one: the credential behind the crew, and whether the scope on the estimate is the scope that actually gets installed.
GAF Master Elite, Licensed & Insured
Yellowstone Roofing is a GAF Master Elite contractor — a manufacturer credential held by roughly two percent of roofing contractors in North America, renewed annually on training, claims history, and license-and-insurance verification. On a commercial job that credential matters even more, because building owners and property managers need documented, insurable work.
We’re licensed and insured in Montana, BBB accredited with an A+ rating, and we send a certificate of insurance to your inbox before the truck arrives. See the areas we serve across south-central Montana.
Employee Crews on Every Job
On a lot of commercial jobs the company that sells the roof isn’t the crew that installs it — the work gets handed off to whoever’s cheapest that week. Not here. Every commercial project runs with our own employees, trained our way, on every single job. That’s how you get consistent seam welds, consistent flashing details, and one point of accountability from first walk-through to final invoice.
The owner walks the roof before we write the number, and you’ll have a real person in Montana to call — not a call center — the whole way through.
Owner-checked work, employee crews on every job, certificate of insurance before the truck arrives, and warranty paperwork at job close.
Your Commercial Roof, Start to Finish
From the first phone call to the warranty packet in your hand, here’s exactly what to expect.
1. You Call or Click
Tell us the building type, roof size if you know it, and what’s prompting the call — a leak, ponding water, age, or a new build.
2. We Schedule
A real person in Billings answers, and you get a firm window for the site visit — not "sometime this week."
3. Roof Assessment
We walk the roof: membrane condition, seams, flashing at curbs and penetrations, drainage. Written, itemized estimate with system options.
4. The Install
Tear-off or recover as specified, insulation and cover board where needed, TPO or EPDM membrane welded and detailed, flashing at every penetration.
5. Final Walk-Through
We walk the roof with you, check every seam and drain, punch-list any items, and clear the site before we sign off.
6. Written Warranty
Manufacturer membrane warranty and our workmanship warranty, registered and emailed after job close. Insurance-ready documentation.
What Bargain Bids Usually Leave Out
There’s always a cheaper number on a commercial roof. Sometimes it’s a legitimate competitor. More often it’s a thinner membrane, a subbed-out crew, or a scope that gets quietly trimmed on install day. Here’s what we include that the lowball bid usually doesn’t.
- GAF Master Elite install — a credential fewer than 2% of roofers nationwide hold, verifiable
- Our own employee crews on every job
- Written workmanship warranty on top of the manufacturer membrane warranty
- Certificate of insurance in your inbox before the crew ever shows up
- An itemized scope that’s the same scope we install — no surprise trims on the roof
What Business Owners Ask Most
It depends on the building, the budget, and how the roof gets used. TPO is a reflective, heat-welded membrane that keeps buildings cooler and holds strong seams — a great fit for a lot of Montana commercial roofs. EPDM is a proven rubber membrane that handles our temperature swings well and is easy to patch and repair down the road. We’ll walk your roof, look at drainage and rooftop equipment, and tell you honestly which system fits — not just which one has the higher margin.
Often, yes. Many flat-roof leaks trace back to a single failure point — a bad seam, flashing at a curb or penetration, or a clogged drain — not the whole membrane. When the roof still has life left, we diagnose the actual problem and fix that, rather than selling you a full tear-off you don’t need yet. When the membrane really is at the end of its life, we’ll show you why and quote a replacement.
Yes. Multi-family and apartment roofing is squarely in our wheelhouse, along with pole buildings, storage facilities, and standalone commercial buildings across the Billings area. We coordinate with property managers and owners on scheduling and access so the work causes the least disruption to tenants and business hours.
Yes — licensed and insured in Montana, and BBB accredited with an A+ rating (accredited since October 2021). We send a certificate of insurance to your inbox before the crew arrives, which matters on any commercial job where building owners and lenders need documented coverage.
Every commercial job runs with our own employee crews. That means consistent workmanship, one point of accountability, and the same people you met at the walk-through actually doing the install. The owner checks the work before we call it done.
