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.

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.
