done right
Commercial flat roofing isn’t the same trade as residential. Different materials, different systems, different failure points. We’ve built our commercial division around it — with the certifications, the warranties, and the experience to back it up.
If you own a commercial building in Flathead Valley — office, warehouse, retail, multi-family, restaurant — we can handle your roof. From small repairs to full replacements to ongoing maintenance, we’re the local crew that knows what we’re doing.
Carlisle SynTec Certified Applicator
Titan Roofing is a Carlisle SynTec Certified Applicator. That’s a big deal in commercial roofing for two reasons:
FIRST, Carlisle is the largest and most respected manufacturer of single-ply commercial roofing systems in the country. Their TPO, EPDM, and PVC products are the gold standard for flat commercial roofs.
SECOND, certification isn’t given out lightly. To become Carlisle certified, a contractor has to demonstrate proper training, technical skill, and a track record of installing their systems correctly. Most commercial roofers in the valley don’t have it.
What it means for you: when Titan installs a Carlisle commercial roof, you get Carlisle’s full manufacturer warranty — backed by the company, not just by us. That’s the kind of warranty that matters when a roof is protecting your business.

our Commercial Process
Free building assesment
We come out, climb the roof, and look at your full system — the membrane, the insulation, the drainage, the flashings, and the penetrations. You get a written report on the current condition and what we’d recommend.
system recommendation
Based on your building, use case, budget, and timeline, we recommend the right system — TPO, EPDM, or PVC — and explain why. We don’t default to whatever’s most expensive. We recommend what fits your situation.
DETAILED PROPOSAL
Full written proposal covering scope of work, materials, timeline, warranty, and price. No surprises. No hidden costs.
PROFESSIONAL installation
Our crew installs the system per Carlisle’s specifications — the only way to qualify for the manufacturer warranty. Insulation, fasteners, membrane, seams, flashings, penetrations, all done right.
INSPECTION & WARRANTY
Final inspection of the completed system. Carlisle manufacturer warranty paperwork delivered. Titan workmanship warranty in writing.
ONGOING MAINTENANCE
Commercial roofs need annual or semi-annual inspections to maintain warranties and catch small issues before they become big ones. We offer service contracts that handle this for you.
Commercial Repairs & Maintenance
Not every commercial roof needs full replacement. We handle:
Active leak diagnosis and repair
Seam repair on existing TPO, EPDM, or PVC
Flashing repair around penetrations, parapets, and edges
HVAC curb and unit flashing
Drain repair and replacement
Annual maintenance inspections (often required to keep manufacturer warranties active)
Hail damage assessment and insurance claim assistance
Roof coatings to extend the life of existing systems

Our Commercial Warranty
Titan Roofing Workmanship Warranty + Carlisle Manufacturer Warranty
Our workmanship is backed in writing. Carlisle’s manufacturer warranty covers the membrane itself — depending on the system and warranty tier, from 15 to 30 years.
Because we’re a Carlisle Certified Applicator, we can offer their highest warranty tiers — something uncertified contractors can’t provide. We’ll go over the specific warranty options for your project at the estimate.
Common Questions About Commercial Roofing
How long does a commercial roof replacement take?
Depends on size and complexity. A small office building might be a week. A larger warehouse can be 2-4 weeks. We schedule around your business operations as much as possible.
Can we stay open during the work?
Yes, in nearly every case. Commercial roof work happens above you — we coordinate with your operations to minimize disruption. We’ll keep you informed about anything that affects access or noise.
What does “Carlisle Certified” actually mean?
It means Titan Roofing has been trained, vetted, and authorized by Carlisle SynTec to install their commercial roofing systems and offer their manufacturer warranties. Many commercial roofers will install Carlisle products without certification — but you don’t get the full warranty when they do. With us, you do.
How do I know which system is right for my building?
That’s what the free assessment is for. We look at your building’s use, climate exposure, current roof condition, budget, and how long you plan to own the building. We recommend the system that fits, and we explain why
Do you handle insurance claims on commercial roofs?
Yes. Hail, wind, and storm damage on commercial roofs are often covered by your commercial property insurance. We document the damage, provide the scope and estimate your insurer needs, and handle the install once the claim is approved.
