EPDM roofing has gained widespread popularity in residential and commercial construction due to its remarkable durability and lasting performance. However, maintaining the longevity and effectiveness of an EPDM roof depends on selecting the appropriate adhesive for installation and upkeep.
That’s why, in this blog post, we will explore the significance of choosing a high-quality adhesive for an EPDM roof, and assess three leading adhesive options currently on the market.
Why Are People Choosing EPDM Roofs?
Ethylene propylene diene monomer, better known as EPDM, is a popular commercial roofing option in the industry because of the advantages it offers business owners. These synthetic rubber membranes are incredibly affordable, environmentally friendly, and durable.
Given their resilience, commercial buildings can last over 50 years in tough weather conditions like strong winds, hail, and temperature changes. Since it is non-toxic and recyclable, EPDM is highly valued for its eco-friendliness as well.
It’s also less expensive than alternative options like metal because of its lightweight design and low expense. EPDM roofs are made of large sheets that have a seamless design that reduces the number of joints and seams, improving aesthetic appeal and lowering the possibility of leaks and water damage.
The excellent combination of longevity, environmental friendliness, affordability, and ease of installation and maintenance that EPDM roofs provide makes them one of the top options for a variety of roofing applications.
> Durable: EPDM resists harsh weather and UV rays, and needs little maintenance
> Eco-Friendly: Recyclable EPDM lasts up to 50 years, reducing waste
> Fire-Resistant: It slows the spread of fires, boosting safety
> Affordable: EPDM is one of the most affordable commercial roofing materials
> Easy Install: Lightweight, so it reduces the risk of leaks during installation
However, for sheets of EPDM to be installed properly and provide effective protection and all the benefits explained here, you need a durable, quality adhesive.
