When we speak of low-slope roof membranes, we are speaking of a category that describes a collective selection of different types of low-slope roof membranes. While the average homeowner doesn’t necessarily need to know the differences between these types, a member of facility personnel, or even the owner of an apartment complex might be better off with informing themselves. You can always talk with Roof Repairs contractor in Palo Alto to get more information than what is provided here.

Fastening A Membrane To A Roof

Ethylene Propylene Diene Terpolymer, better known as simply EPDM, is a roof membrane made of extremely durable and synthetic rubber. Fastening this membrane to your home can be done in a multitude of ways, starting with the use of concrete pavers, or even large stones – both of which are commonly referred to as ballast – which are placed upon the membrane, as well as the above-deck insulation to secure it.
Another way to secure the membrane is to forgo the ballast, and instead use a mechanical attachment or adhesive. When we are talking about a mechanical attachment, we are talking about a complex system of round plates which are fastened along the inside of the laps in the membrane itself, leaving a few inches of space between. You can check whether this system has been used on your roof by dragging your food over the membrane. If wrinkles occur, you are most likely dealing with a mechanically attached membrane.
When we are talking about a membrane fastened with adhesive, we are talking about a membrane joined along the seams with either butyl bonding adhesive, or double-sided adhesive tapes. To check whether this system was used on the membrane of your roof, you can check whether plates are visible underneath that are parallel lined with the membrane’s lap.

Types of Membranes Available

Alongside the aforementioned EPDM membrane, there are also other types of membranes, starting with the so-called TPO membrane.TPO membranes are oftentimes white in color and can be fastened in all previously mentioned types of ways (using ballast, an adhering system, or mechanically attachment). However, more often than not, you will find them mechanically attached. Over recent years, TPO membranes have made a more and more frequent appearance in the industry due to their practicality. Since TPO membranes are made of thermoplastic, their seams can easily be fused with nothing more than hot air which makes them easily turned into one uniform membrane.
