They possess exceptional UV resistance properties, preventing premature aging and deterioration caused by prolonged exposure to sunlight. This characteristic contributes to the longevity of the roof and minimizes maintenance requirements.

• Flexible Membrane Allows for Easier Installation: EPDM roofing systems feature a flexible membrane that simplifies the installation process, especially when dealing with complex areas like flashings and penetrations. This flexibility ensures a snug fit and efficient sealing, reducing the chances of leaks and enhancing the overall performance of the roof.

• Cost-Effectiveness: EPDM roofing systems offer a cost-effective solution for both commercial and residential buildings. Compared to other roofing materials, the initial installation cost of EPDM is relatively affordable. Additionally, its longevity and low maintenance requirements translate into long-term cost savings for property owners.

Disadvantages of EPDM Roofing Systems:

• Higher Risk of Structural Overheating in Extreme Heat: EPDM roofs tend to absorb more heat in extreme temperatures, which can lead to a higher risk of structural overheating. This is particularly relevant in regions with intense heat waves, and appropriate insulation and ventilation measures should be implemented to mitigate this risk.

• Punctures Easily, Limit Walking on It: While EPDM roofs are highly resilient against hail and abrasion, they can puncture easily if subjected to sharp objects or excessive foot traffic. To maintain the integrity of the roof, walking on it should be limited or avoided whenever possible. This precautionary measure prevents unnecessary damage and extends the lifespan of the roofing system.

PVC Roofing: Durable and Easy to Install
PVC roofing is a type of synthetic material made from polyvinyl chloride. It offers numerous advantages, including excellent resistance to wind, moisture, fire, and chemicals. Typically, PVC roofing comes in rolls ranging from 50 to 100 feet in length and 5 to 12 feet wide. It can be installed using different methods, such as full adhesion, mechanical fastening, or ballasting and seam welding.
One of the notable benefits of PVC roofing is its long lifespan, which typically ranges from 15 to 30 years. Additionally, PVC roofing material comes in smaller rolls compared to other options like EPDM, making it easier to handle and install. Consequently, this type of roofing system works well for both smaller commercial and residential projects.
In summary, PVC roofing provides a durable and convenient solution for various roofing needs. With its superior resistance and relatively straightforward installation process, it is an excellent choice for smaller-scale installations in both commercial and residential settings.
