EPDM Roofing in Green Bay, WI

EPDM stands for ethylene propylene diene monomer, a synthetic rubber that has become one of the most trusted materials for flat and low-slope roofs. It arrives as a single-ply membrane, a large sheet of durable rubber rolled out across the roof deck and bonded into a continuous, watertight surface. The classic EPDM membrane is black, which many building owners recognize on commercial rooftops throughout Green Bay, though white and reflective options are also available.

When people talk about a rubber roof, EPDM is almost always the material they mean. It has earned that reputation over decades of dependable service on everything from warehouses and storefronts to home additions. Unlike built-up gravel roofs or older coating systems, EPDM goes down as a single sheet, which means far fewer places for water to sneak through. Pierce Roofing installs EPDM for both commercial buildings and residential low-slope sections, backing every project with a 10-year workmanship warranty and $2 million in insurance. As an Atlas PRO+ Platinum certified contractor, we hold our flat-roof work to the same standard as every shingle roof we install.

Northeast Wisconsin puts roofing materials through a brutal cycle of freezing, thawing, and refreezing. Water works into small gaps, expands as it freezes, and slowly pries seams and membranes apart. EPDM's greatest strength is how well it handles this abuse.

The rubber membrane stays flexible even in deep cold, so it moves with the building instead of cracking under stress. Roofs expand and contract as temperatures swing from summer heat to subzero January nights, and a brittle material eventually gives out at the seams. EPDM's elasticity lets it flex through those swings year after year without failing. That cold-weather flexibility is a key reason so many Green Bay property owners choose EPDM over stiffer alternatives. Owner Michael Pierce has spent more than 30 years watching how different systems age in this climate, and EPDM's freeze-thaw resistance is a big part of why it remains a go-to recommendation for local flat roofs.

One reason EPDM works on so many buildings is that it can be installed several ways. The right choice depends on your deck, insulation, wind exposure, and budget.

EPDM and TPO are the two most common single-ply membranes, and each has clear tradeoffs. TPO's white surface is highly reflective, bouncing heat away and helping with cooling costs on sun-exposed commercial buildings. EPDM's classic black membrane absorbs heat, which can actually help shed snow, and its cold-weather flexibility often edges out TPO in a climate defined by hard winters.

There is no single winner. The best membrane depends on your building, its exposure, and your priorities. For larger properties, our commercial roofing team helps weigh reflectivity against cold performance so you invest in the system that truly fits your building.

EPDM's low-maintenance nature is a major part of its appeal. The membrane resists weathering and UV exposure, and when a puncture or seam issue does appear, repairs are straightforward and affordable rather than a full replacement. A quick patch today keeps a minor problem from becoming a costly one later.

To protect that long service life, we recommend routine inspections, especially after harsh winters when ice and heavy snow put the most strain on a flat roof. A twice-yearly look at seams, flashings, and drains keeps water moving off the membrane and stops ponding before it shortens the roof's life. Our roof maintenance programs catch small concerns early and help your EPDM roof reach the upper end of its 30 to 50 year potential. Ready to talk options for your building?
