Flat roofing is a common choice for many commercial buildings and even some residential properties in Connecticut and Massachusetts. Whether you own a retail space in Springfield, a multi-family property in Windham, or a modern home with a flat roof in Westport, choosing the right system is essential for durability, energy efficiency, and long-term protection.
At JP Carroll Roofing, we specialize in flat roof installation, roof repair, and maintenance. The two most popular flat roofing systems we install are TPO (Thermoplastic Olefin) and EPDM (Ethylene Propylene Diene Monomer). This guide will walk you through the basics of flat roofing, explain the differences between TPO and EPDM, and help you decide which option is right for your property.
Why Flat Roofing?
Flat roofs aren’t completely flat — they have a slight pitch to allow water drainage — but they provide unique advantages compared to steep-slope roofing:
- Cost-Effective – Typically more affordable for large commercial spaces.
- Efficient Use of Space – Can support HVAC units, solar panels, or rooftop amenities.
- Modern Aesthetics – Increasingly popular for contemporary homes.
However, flat roofs also require expert installation and maintenance to prevent water pooling and leaks.
What Is TPO Roofing?
TPO (Thermoplastic Olefin) is a single-ply roofing membrane made from a blend of rubber and other materials. It has become one of the fastest-growing flat roofing options in the United States.
Benefits of TPO
- Energy Efficiency – White reflective surfaces help reduce cooling costs in summer.
- Durability – Resistant to punctures, tears, and UV rays.
- Flexibility – Handles building movement and temperature fluctuations well.
- Eco-Friendly – TPO membranes are recyclable.
Considerations for TPO
- Installation Expertise – Requires proper welding of seams for best performance.
- Variable Quality – Not all TPO products are created equal; quality matters.
What Is EPDM Roofing?
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber roofing membrane that has been used for decades in flat roofing applications.
Benefits of EPDM
- Proven Track Record – Time-tested with decades of reliable performance.
- Durability – Highly resistant to weathering, UV rays, and hail.
- Flexibility – Performs well in both hot summers and freezing winters.
- Cost-Effective – Generally less expensive than TPO.
Considerations for EPDM
- Appearance – Typically black, which absorbs heat and may increase cooling costs in summer.
- Seam Strength – Relies on adhesives, which must be properly installed to avoid leaks.
TPO vs. EPDM: Key Comparisons
| Feature | TPO | EPDM |
| Color Options | White, gray, tan (reflective) | Primarily black (some lighter options) |
| Energy Efficiency | Highly reflective, reduces cooling costs | Absorbs heat, may raise cooling costs |
| Durability | Resistant to punctures & UV rays | Proven long-term reliability |
| Installation | Heat-welded seams, skilled labor | Adhesive seams, simpler process |
| Cost | Moderate to high | Lower upfront cost |
| Lifespan | 20–30 years with maintenance | 20–30 years with maintenance |
Performance in Connecticut & Massachusetts
- TPO Roofing – A strong choice for energy-conscious property owners in towns like Westport or Springfield, where summer cooling costs can add up.
- EPDM Roofing – A reliable option for businesses in colder inland areas like Mansfield and Windham, where proven weather resistance is critical.
Both systems, when properly installed, can handle New England’s snow loads, heavy rain, and coastal storms.
Maintenance for Flat Roofs
Flat roofs require regular maintenance to stay in top condition. JP Carroll Roofing recommends:
- Annual Inspections – Check for punctures, seam issues, or pooling water.
- Prompt Repairs – Address minor issues before they become major leaks.
- Gutter & Drain Cleaning – Keep water flowing away from the roof.
- Snow & Ice Management – Heavy accumulation can stress flat roof structures.
Proactive care helps maximize the lifespan of your TPO or EPDM system.
