If you have been looking for a new roofing system for your building, and you have come across EPDM systems, you might be wondering whether this is the right solution for you. This basic guide will look at what this type of system is and some of the benefits that it can offer, along with tips for installation.
What Is EPDM?
EPDM is a popular type of roofing material that has been around for nearly 60 years. Those who have flat and low-sloped roofs, whether commercial or residential, have found that it is a good roofing application that offers some excellent benefits. EPDM is available in different thicknesses (45mm, 60mm, and 90mm) and styles, and it is even available in two different colors – black and white. These colors can help to confer energy savings. Those who live in warm climates might want the white for their roof, as it will reflect the rays of the sun and keep the building cooler, for example.
Main EPDM Roof Advantages
This type of roofing system has gained popularity because of the many benefits that it can offer. It has the ability to resist extreme temperatures and it holds up well if there is standing water on the roof. It is durable and can last for decades. It tends to be lightweight and has Class A fire resistance. Repairs are simple, and this is an inexpensive option for those who are looking for a quality roofing system.
Types of EPDM Roofing
Many companies today offer EPDM, but there are two main choices when you are choosing this product. You can choose the roofing membranes, which are a popular option for many businesses. There is also a liquid EPDM that could be used. This version tends to be easy to apply, and it has gained in popularity.
Installing the Roofing Membranes
The installation of the membranes is simple, but it will require preparation of the roof before beginning. The roof needs to be extremely clean and free of all dirt and debris. It also needs to be completely dry before beginning. The membranes are then laid out on the roof for about half an hour so wrinkles can be removed. When doing this, they are laid so that 3” of material hangs over the edge of the roof. The membranes are then folded back over themselves.
At this time, the contractors will get the EPDM adhesive ready, and will then apply the adhesive to the roof. The membranes are then folded back into place when the adhesive is tacky but not wet. A push broom can be used to ensure adhesion and to help remove any wrinkles. It is a slow but simple process, and many business owners find that it tends to be best to hire a professional to take care of the installation to make sure it is done correctly.
When it comes to the liquid EPDM, the installation process does tend to be easier, and you may want to do it on your own. You still need to clean the roof thoroughly, and you need to be sure that you have a dry roof before you start. You would then mix up the liquid EPDM with the catalyst to activate it. Then, it can be applied to the roof with a paint roller and a paintbrush, which can help to get into some areas that the roller can’t.
Now that you have a better understanding of what EPDM is and how it is applied, you can make a decision on whether it might be right for your business.
