Is EPDM or TPO Better for My Lake County Property?

When it comes to the roofing of your Lake County home, there are many options to consider for your roofing material. But how can you tell which one is the best for your situation? To help you make an informed decision,, and traits that each material possesses and the weaknesses that you will want to know about.

EPDM

EPDM, commonly known as a “rubber roof” or ethylene propylene diene monomer, gets its name from the chemicals mixed in various proportions to form it. It’s manufactured in large sheets or rolls and is quick and easy to install, on top of being one of the most inexpensive roofing materials around. EPDM roofing membrane is very lightweight, so the roof deck will not need any reinforcement. And because there are few seams, leaks are rare and a good quality EPDM can last for decades.

Pros

EPDM generally comes in at the lowest price per square foot for flat or low-sloped roofs. Generally, it is long-lasting with a lifespan of over 20 years. And if purchased in white, since it is easily paired with polyiso insulation, it can be a very energy-efficient roof choice.

Cons

When installed in the wrong environment, EPDM can quickly become fragile, requiring it to be replaced sooner than later. Some methods of installing EPDM are also more expensive than installing similar roofing types, like TPO, so it’s important to hire a local roofer that will understand which option is truly the best one for your needs.

TPO

TPO, properly known as Thermoplastic Polyolefin, is made up of a single layer of synthetics, usually a blend of polypropylene and ethylene-propylene rubber. Its primary advantage is that it’s typically the lowest material cost for single-ply membrane roofs. It typically comes in white on top, which can help reflect the sun’s light and stop heat buildup within the building.

TPO can be attached with adhesives, fastened directly to the roof deck, or even heat welded in places around chimneys and other protrusions. It resists corrosion, mildew, and algae growth, and does not require pressure washing, making it even easier to care for during the annual checkup.

Pros

TPO provides outstanding resistance to ozone, ultraviolet rays, and some chemical exposure at a low cost. It reflects heat radiation better than EPDM and resists mold growth, dirt accumulation, tears impacts, and punctures.

Cons

Heat welding the seams requires a very high-quality installation to hold up over time. Some formulations of TPO may not last much past the 10-year mark, and newer technology makes for a lack of a proven track record.
