The choice between TPO and EPDM roofing membranes depends on various factors, including climate, installation requirements, and long-term considerations. Connecticut commercial roofing contractors share pros and cons of these materials.

TPO Roofing

Pros:

Energy Efficiency: TPO is known for its energy-efficient properties, contributing to a building’s overall energy performance.

Resistance to Algae and Mold: TPO has inherent resistance to algae and mold growth, which can be advantageous in humid climates.

Cons:

Durability: While TPO is durable, the long-term performance can be influenced by the quality of the material and installation. Some lower-quality TPO membranes may experience issues such as seam failures.

Cost: TPO roofing materials can be more expensive than EPDM, depending on the specific product and manufacturer.

EPDM Roofing

Pros:

Proven Track Record: EPDM has a long history of successful use in various climates, including colder regions. It has a proven track record for durability.

Resistance to Weathering: EPDM is known for its resistance to weathering, UV radiation, and ozone exposure.

Cost-Effectiveness: EPDM roofing materials are often more cost-effective than TPO, making them an attractive option for budget-conscious projects.

Cons:

Dark Color: EPDM is typically available in dark colors, which can absorb heat. In hotter climates, this may lead to higher cooling costs.
