Flat & Low Slope EPDM/TPO Roofing in Duluth, MN
Flat and low slope roofs are common across Duluth on garages, additions, and the flatter commercial adjacent buildings scattered through Lincoln Park and along Central Entrance, and they face a very different set of problems than the steep pitched roofs found in Congdon Park or the Hillside. Rapid snowmelt off Lake Superior, combined with heavy rainfall events, means standing water can sit on a poorly installed flat surface for days at a time, and Duluth’s dramatic temperature swings between deep winter cold and summer heat put constant stress on any membrane asked to hold that water back.
Perrins Roofing installs EPDM and TPO flat roofing systems built for Duluth’s climate. Whether you have a detached garage near Lakeside or a low slope commercial building near Miller Hill, we install a membrane system matched to your structure, drainage needs, and exposure.

EPDM is a synthetic rubber membrane built to excel through extreme temperature swings, exactly what Duluth delivers between deep winter cold and summer lake heat. Its exceptional flexibility allows the material to expand and contract smoothly without cracking or pulling away from roof edges. Highly resistant to ozone degradation, EPDM is a strong choice for low slope additions and detached garages throughout Duluth’s residential neighborhoods, keeping standing water from compromising the structure below.
TPO combines long term rubber durability with hot air welded seams that create a monolithic, physically fused surface across your entire roof. Its bright, reflective white surface bounces solar energy away from your property, helping lower interior cooling costs during Duluth’s warmer summer stretches. This fused seam construction makes TPO exceptionally resistant to punctures and tears, a strong fit for modern flat roofed builds near the Miller Hill corridor.
Flat roof performance depends entirely on precision at the perimeter and seams. We use advanced bonding adhesives and heavy duty termination bars to lock the membrane tightly around parapet walls, chimneys, and roof drains common on Duluth’s older commercial buildings. Every pipe penetration receives multi layered reinforcing boots, ensuring your decking stays dry even through rapid lake effect snowmelt.
