Flat Roofing Insights from a Commercial Roofing Contractor
If you own or manage a commercial building, you've probably heard roofers toss around letters like EPDM, TPO, or PVC. Flat roofs come in plenty of types, each with its own pitch. Sorting through them can feel like a guessing game. Any commercial roofing contractor in Wisconsin will tell you that choosing what fits your building isn't always simple.
This article explains what each flat roof system really means, how it performs, and what kind of upkeep it needs to stay in good shape.
Why Flat Roofs Are Common in Commercial Buildings
They’re practical, efficient, and easier to use for applications such as HVAC systems or solar panels. But flat roofs aren’t completely flat. They’re built with a gentle slope that helps water drain away, preventing puddles or pooling after a heavy rain.
Flat roofs aren’t like traditional pitched ones. That’s why working with an experienced commercial roofing contractor in Wisconsin is so important.
Common Flat Roof Systems You’ll Hear About
Here’s a breakdown of the most popular types of flat roofing materials and how they stack up.
EPDM (Ethylene Propylene Diene Monomer)
EPDM is basically a durable rubber membrane. It’s been around for decades and is known for its flexibility and long lifespan.
Pros
● Handles temperature changes well
● Simple to install and repair
● Resistant to UV rays
Cons
● Dark color absorbs heat
● Can be punctured by debris if not maintained
TPO (Thermoplastic Polyolefin)
TPO is a new favorite for commercial buildings. It’s a single-ply white membrane that reflects sunlight and resists chemical buildup.
Pros
● Energy-efficient in warmer months
● Strong seams and durable structure
● Resists mold and dirt buildup
Cons
● Quality varies between manufacturers
● Improper installation can shorten its life
PVC (Polyvinyl Chloride)
PVC roofs are similar to TPO but tend to last longer. They’re known for their excellent resistance to water and chemicals—making them ideal for restaurants, factories, and buildings with rooftop ventilation.
Pros
● Highly resistant to grease and chemicals
● Reflective surface helps manage heat
● Long service life
Cons
● More expensive to install upfront
● Not as flexible in extreme cold
BUR (Built-Up Roofing)
BUR is the old-school layered system made from hot asphalt and reinforcing fabric, finished off with gravel or a reflective coating. You've probably seen it on older downtown buildings or warehouses that have held up for decades.
Pros
● Time-tested durability that's hard to beat
● Excellent resistance to leaks and pooled water
● Stands up well to people walking or working on the roof
Cons
● Heavy once installed, so it needs solid support
● The setup isn’t quick—expect some noise, heat, and mess
● Maintenance Matters More Than You Think
A BUR roof will last, but only if it's looked after. Regular checks for loose gravel, blisters, or cracks can make the difference between a simple patch job and a full tear-off later.
Regular inspections can catch these problems early, saving you a lot of stress later. A trusted roofing repair service in Wisconsin can address these minor issues before they escalate into major problems.
Here’s a simple checklist to help keep your flat roof in good shape:
● Check after every major storm
● Clear out leaves, branches, or any debris from drains
● Inspect seams, flashing, and sealants for cracks or wear
● Book a professional inspection twice a year
