EPDM and TPO Roofing Backed by a 10-Year Workmanship Warranty
Most flat roof problems start invisibly. A small membrane crack, a failed seam at a drain, water working under the surface where no one would think to look. By the time the leak shows up on the ceiling below, the insulation underneath is already saturated, and the repair bill is several times what it would have been if someone had caught it earlier. Flat roofing rewards homeowners and property managers who pay attention to it before it forces them to.
Heins Contracting installs and repairs flat roofing across Southern Wisconsin for both residential and commercial properties. We work primarily with rubber and TPO roofing systems, with infrared inspection technology built into every estimate to catch trapped moisture and subsurface damage that visual inspections miss. Every flat roofing project includes our 10-year workmanship warranty, in addition to manufacturer coverage for the membrane.
What Makes Flat Roofing Different?
Flat roofing doesn't shed water the way pitched roofs do. Where a steep-slope roof relies on gravity to move rain off the surface, a flat roof depends on properly positioned drains and scuppers to do that same work. The membrane bears more direct contact with standing water, more UV exposure during summer, and more freeze-thaw stress at the seams during winter. Each of those conditions degrades materials in different ways, which makes the membrane choice and the installation method as important as the material itself.
That's why contractor experience matters more on flat roofs than on pitched ones. A small mistake during a flat roof installation or repair can cost hundreds of thousands of dollars in interior damage if the membrane fails. We've worked with these systems long enough to know what holds up in Wisconsin and what doesn't.
Flat Roofing Systems We Install
We’re trained to install several types of flat roofs, including EPDM and TPO.
EPDM (Rubber) Roofing
EPDM is a synthetic rubber membrane, and it's the product most people are referring to when they say "rubber roofing." It's been the standard for flat and low-slope applications for decades, and its longevity track record is one reason it's still widely used. The material bonds well to most substrates, handles temperature swings without cracking, and holds up through Wisconsin's freeze-thaw cycles without going brittle. EPDM is typically installed in large sheets, which reduces the number of seams and lowers the risk of water infiltration at joints.
TPO Roofing
TPO uses heat-welded seams instead of adhesive or seam tape, creating a continuous bond at every joint. Seam strength is the defining feature, particularly on commercial applications where large membrane areas need consistent performance over time. TPO also reflects UV more effectively than darker membranes, which can reduce heat gain on sun-exposed buildings during Wisconsin's warmer months.

Common Questions About Flat Roofing in Southern Wisconsin
EPDM and TPO systems have long service lives when properly installed and maintained, with some systems reaching 20 to 30 years before needing replacement. The variables that move that range up or down are installation quality, maintenance frequency, and how aggressively the roof drains during heavy rain.
Repair is often the right answer when damage is localized, and the underlying insulation hasn't been compromised. The infrared inspection is what tells us which situation you're in. When moisture has spread beyond the visible damage, and the insulation below is wet, replacement usually becomes more cost-effective than chasing repairs that won't hold.
Infrared technology detects temperature differences beneath the membrane surface that visual inspection can't pick up. Trapped moisture retains and releases heat differently than dry insulation, so the scan identifies wet areas behind otherwise intact-looking membranes.
Freeze-thaw cycles stress flat roofing membranes most aggressively at seams and drainage points, where water tends to collect before freezing. Standing water that freezes overnight can work into small gaps and expand them. Snow load also distributes differently across a flat surface than across a pitched roof, so monitoring matters more during heavy winters. Keeping drains clear before the first hard freeze is one of the simplest forms of protection.
