EPDM Roofing Repair

If your building has a flat or low-slope roof, chances are you’ve heard of EPDM roofing. Known for its long-lasting performance and cost-effectiveness, EPDM (Ethylene Propylene Diene Monomer) is a popular single-ply rubber roofing material used in commercial and residential applications. It has been trusted for decades across various industries due to its proven durability and ease of installation.

Like any roofing system, though, EPDM can develop issues over time. That’s why regular maintenance and prompt repairs are key to keeping it performing at its best. At Hardesty Roofing, we provide EPDM roof repair services throughout Richmond, Charlottesville, the Tri-Cities, Northern Neck, and Tidewater areas, and we’re here to share what you need to know about this material.

Why Choose EPDM Roofing?

EPDM is widely recognized for its reliability and versatility. It offers several major benefits for building owners and property managers.
First, EPDM roofs are highly durable. When properly installed and maintained, they can last 20 to 30 years. Their rubber composition enables them to withstand UV rays, temperature fluctuations, and even hail without degrading easily.

Next, EPDM is cost-effective. The material itself is affordable, and installation is relatively quick compared to more complex roofing systems. This makes it a solid choice for larger surfaces or budget-conscious projects.

Another advantage is flexibility. The material can expand and contract with changing weather conditions without cracking or splitting. It also performs well in both hot and cold climates.

Finally, EPDM is environmentally friendly. It is recyclable and can be installed with minimal impact on the structure or environment.

Understanding the Drawbacks

Despite its strengths, EPDM has its limitations. One common issue is punctures and tears, especially on roofs with heavy foot traffic or sharp debris. Unlike some thicker materials, EPDM can be easily punctured if not protected.

Additionally, seam failure can occur over time. While the seams are sealed during installation, weather, age, and movement can cause them to loosen or pull apart.

Another drawback is appearance. EPDM is typically black, which absorbs heat. This can increase cooling costs unless a reflective coating is applied. Some versions are available in white, but they are less common.

Lastly, improper installation often leads to premature issues. Like all roofing systems, EPDM must be installed by experienced professionals to ensure performance and longevity.

Common EPDM Roof Problems

While EPDM is a durable material, it still needs occasional maintenance. Catching problems early can prevent more extensive and costly repairs later.

1. Punctures and Holes

Sharp debris, tools, or frequent foot traffic can puncture the rubber membrane. Once damaged, water can enter the building and cause structural problems. Even small holes can lead to big headaches if not addressed. Repairs involve cleaning the area and applying a compatible EPDM patch. The patch is secured with adhesive and pressure to create a watertight seal.

2. Seam Separation

EPDM is installed in large sheets, which are seamed together. Over time, these seams may loosen due to temperature changes, moisture, or movement in the building. Once the seams separate, water can easily seep in. We fix this by reapplying seam tape or adhesive, depending on the roof's age and condition. For larger separations, a patch may be needed.

3. Shrinkage

All roofing materials expand and contract, but EPDM is known to shrink slightly over time. When this happens, the membrane can pull away from walls or seams, leaving areas exposed. The solution typically involves resecuring the membrane or adding new flashing to prevent water from entering.

4. Ponding Water

Flat roofs sometimes collect water if drainage systems are clogged or poorly designed. Ponding water stresses the membrane, leading to deterioration. Long-term ponding can also lead to mold or damage to the roof deck. Remedies may include installing tapered insulation, improving drainage, or reinforcing the affected area with new material.

5. Cracked or Damaged Flashing

Flashing seals the areas where the roof meets walls, vents, and HVAC units. If the flashing cracks or lifts, water can seep in behind it. This is a common source of leaks on EPDM roofs. Replacing damaged flashing and properly sealing the edges solves this problem. We also check the surrounding areas to make sure no other sections are at risk.

How EPDM Roof Repairs Are Done

When you call Hardesty Roofing for EPDM roof repair, we start with a thorough inspection. We examine seams, flashing, drainage, and the surface for signs of damage. Sometimes, a leak may appear inside the building but originate from a different part of the roof. That’s why we trace the problem carefully before recommending repairs.

Once the issue is identified, we clean the area and prepare the surface for repair. Next, we apply a patch, seam tape, or replacement flashing depending on the situation. Every repair is performed using manufacturer-approved materials to ensure a secure bond with your existing roof.

Our goal is always to restore the waterproof integrity of your roof and prevent further issues from arising. We work efficiently to minimize disruption and protect your building during the repair process.

When Repairs Aren’t Enough

EPDM roofs can last for decades, but eventually, age and wear catch up with them. If your roof has multiple punctures, widespread seam failures, or recurring leaks, it may be time to consider replacement rather than repair.

In many cases, a recovery system can be installed over the existing roof. This adds a new membrane and insulation without tearing off the old one. It can save time and reduce costs compared to a full removal.

We will always provide an honest assessment and walk you through the pros and cons of repair versus replacement. Our goal is to give you the best long-term solution for your property and budget.
