Commercial EPDM Roofing Repair, Replacement & Installation in NH

EPDM Rubber Roofing for Commercial Businesses

When your flat or low-slope roof starts giving you problems, leaks, pooling water, or aging seams, it might be time to talk about EPDM. Known for its flexibility, toughness, and long lifespan, EPDM (ethylene propylene diene monomer) rubber roofing is one of the most trusted single-ply roofing solutions around. And we don’t say that lightly.

At Conde Roofing & Construction, we install high-performance black and white EPDM systems across New Hampshire, Massachusetts, Vermont, and Maine. Whether you’re looking to replace an aging membrane or build from scratch, we’ll walk you through your options, no pushy sales, no fluff, just roofing that works.

What Is EPDM Roofing?

EPDM is a synthetic rubber roofing membrane designed for low-slope commercial and residential roofs. It’s made from ethylene and propylene, two of the most durable ingredients in the roofing world, and it holds up against just about anything New England weather throws its way.

You’ll find it in two main colors:

    • Black EPDM: Absorbs heat, making it ideal for colder climates.
    • White EPDM: Reflects sunlight, lowering cooling costs in warmer months. Just note, it tends to be pricier than black EPDM and even slightly more expensive than TPO.

EPDM Roofing System Components

A typical EPDM system from Conde Roofing includes:

  • EPDM Membrane: Non-reinforced or reinforced, available in 60-mil and 90-mil thicknesses

  • Bonding Adhesives & Seam Tapes: Applied under controlled conditions for better adhesion

  • Flashing & Drainage Components: Keeps your vulnerable areas sealed up tight

  • Insulation Layers (Optional): Adds thermal resistance and energy efficiency

And yes, if we’re talking white EPDM, we’re installing it with the correct adhesives and tools to preserve its integrity through both frigid winters and hot, humid summers.

Why Homeowners & Business Owners Choose EPDM

We install EPDM because it delivers. Plain and simple. Here’s what makes it stand out:

Long Lifespan

EPDM can last 30+ years with minimal upkeep. It doesn’t crack or become brittle in cold weather, and it resists UV degradation like a champ.

Flexibility in Cold Weather

Some roofs go stiff in the cold. Not EPDM. It stays flexible even at -40°F, making it ideal for homes and buildings across New England.

Strong Against Storms

EPDM's elasticity makes it hail-resistant, tear-resistant, and less prone to punctures than you’d expect. It’s even rated UL 2218 Class 4 for superior hail resistance.

Easy to Install & Repair

Fully adhered EPDM installs cleanly, and when repairs are needed, patches bond tightly with the existing membrane. For white EPDM, pre-applied seam tape helps eliminate air bubbles and ensures strong, consistent seams.

Eco-Friendly Option

White EPDM systems can reflect up to 80% of solar radiation, helping you reduce cooling costs and qualify for LEED® points depending on the system used.

Black vs. White EPDM: Which One’s Right for You?

Here’s a quick breakdown to help you compare:

Feature Black EPDM White EPDM
Heat Absorption High (warms building) Low (reflects heat)
Best For Cold climates Warmer climates
Energy Efficiency Better for heating Better for cooling
Price Point $$ (more affordable) $$$ (more expensive)
UV Resistance Excellent Excellent
