EPDM Installation Process

The installation process for EPDM roofing involves several steps. It is important to follow these steps carefully to ensure a proper and long-lasting installation.

Surface Preparation

Before installing the EPDM membrane, the surface must be thoroughly cleaned and prepared. This includes removing any debris, dirt, and loose materials. It is crucial to have a clean and dry surface for the EPDM to bond properly.

Laying and Relaxing the EPDM Membrane

Once the surface is prepared, the EPDM membrane can be laid out. It needs to be relaxed before installation to allow for expansion and contraction. This is important to ensure the membrane can adjust to temperature changes without causing any damage.

Adhesive Application

The EPDM membrane is then glued to the roof surface using a water-based adhesive. This adhesive provides a strong and secure bond. For details and edges, a contact adhesive is used to ensure proper adhesion and prevent any lifting or separation.

Trim Installation

To provide a clean and functional finish, EPDM trims, such as edge trims and drip trims, are installed. These trims help to seal the edges, corners, and other vulnerable areas of the roof, preventing water infiltration and enhancing the overall aesthetics of the roof.

It is important to note that EPDM installation requires expertise and precision. Hiring a professional roofing contractor with experience in EPDM installation is highly recommended to ensure the best results.

Maintaining EPDM Roofing

EPDM roofing is known for its minimal maintenance requirements, making it a popular choice for commercial and industrial applications. However, regular inspections and cleaning are crucial to ensure the longevity and performance of your EPDM roof.

To keep your EPDM roofing in optimal condition, follow these maintenance tips:

1. Cleaning EPDM Roofing

Regularly clean your EPDM roof to remove dirt, debris, and other pollutants. This can be done by:

  • Sweeping the roof surface to remove loose dirt and debris.
  • Hosing off the roof with a gentle stream of water to wash away remaining dirt.
  • Applying a rubber roof cleaner to eliminate stubborn stains or growths.

Remember to follow the manufacturer’s instructions when using any cleaning products or solutions.

2. Conducting Regular Inspections

Perform regular inspections of your EPDM roofing to identify any signs of damage or wear. Inspect the following areas:

  • Roof surface for tears, punctures, or blistering.
  • Edges and seams for any signs of separation or deterioration.
  • Drains and gutters for blockages or damage.

It is recommended to inspect your EPDM roof during mild weather conditions and after periods of adverse weather, such as storms or heavy rainfall.

Tip: Create a maintenance schedule to ensure regular inspections and cleaning are carried out consistently.

By following these maintenance practices, you can maximize the lifespan and performance of your EPDM roofing.

Common EPDM Problems

While EPDM roofing is known for its durability, it is not immune to certain issues that may arise over time. Understanding these common EPDM problems is essential for maintaining the integrity of your roof and ensuring its longevity.

1. Shrinkage

One common problem faced by EPDM roofing is shrinkage. As the roof ages, the membrane may shrink, causing it to separate from certain areas of the roof. This can create stress points that are vulnerable to water infiltration, potentially leading to leaks and damage to the underlying structure. Regular inspections can help detect shrinkage early on and prompt the necessary repairs.

2. Defective Seams

Defective seams are another issue that can occur with EPDM roofing. If the seams are not properly installed or if they deteriorate over time, water can penetrate through them and compromise the roof’s integrity. Regular visual inspections and maintenance can help identify any weak or damaged seams that require attention.

3. Damage from Severe Weather and Debris

EPDM roofs are designed to withstand extreme weather conditions, but severe storms and wind-driven debris can still cause damage. Hail, strong winds, and falling tree branches can puncture or tear the EPDM membrane. It’s important to inspect the roof after severe weather events and promptly address any damage to prevent further issues.

4. Tradesperson Damage

During maintenance or repair work on other parts of the building, tradespersons can unintentionally cause damage to the EPDM roof. Tools, equipment, or heavy foot traffic can lead to punctures, tears, or other forms of damage. Proper communication and coordination with contractors and tradespeople can help minimize the risk of such damage.

EPDM Patching and Repair

When faced with common EPDM problems, timely patching and repair are crucial to maintaining the functionality and longevity of the roof. Depending on the extent of the damage, there are different patching and repair methods that can be employed:

  • Self-adhesive patches: Small punctures and tears can often be repaired using self-adhesive EPDM patches. These patches are designed to adhere to the existing membrane and create a watertight seal.
  • Liquid EPDM coatings: For larger areas of damage, liquid EPDM coatings can be used as a repair solution. These coatings are applied directly to the damaged area to create a seamless, protective barrier.
  • Professional roof repair: In cases where the damage is extensive or complex, it is advisable to hire a professional roofing contractor who specializes in EPDM roofs. They have the expertise and equipment to accurately assess and repair the damage, ensuring the roof’s integrity.

Regular inspections, prompt repairs, and proper maintenance can help address common EPDM problems and extend the lifespan of your roof. By staying proactive and addressing issues as they arise, you can ensure the continued performance and durability of your EPDM roofing system.

EPDM Roofing vs Other Roofing Materials

When it comes to choosing the right roofing material for your building, it’s essential to consider the advantages and disadvantages of each option. In comparison to felt and GRP roofing, EPDM roofing stands out as a strong and versatile choice that offers several key benefits.
