Do you have a flat or slope roof? Are you considering an EPDM membrane as the roofing material?

EPDM has been more commonly used on commercial buildings for decades. So, even with more homeowners interested, it’s hard to find anything that isn’t commercial roofing related.

Commercial and residential roofing may be in the same industry, but they’re completely different. So, let’s look at it from a residential perspective.

45-mil is the thinnest and cheapest option but is more vulnerable to punctures. 60-mil is the most commonly used thickness for its durability while still being cost-effective.

90-mil is the thickest and most durable option, which makes it great for areas with harsh weather conditions. It’s the most expensive but it provides the greatest durability and lifespan.

I recommend going with 60-mil at the least, but which one you choose ultimately depends on your budget and area.

What color is an EPDM roofing membrane?

EPDM roofing membranes are mainly black, but white is also available. However, the one you should choose depends on your specific needs, the room below, and your area’s temperatures.

Black EPDM membranes absorb heat, which will make the room below warmer. If your area sees frequent high temperatures, I don’t recommend using it over a bedroom or living space.

Instead, you should choose white for better reflectivity and energy efficiency to avoid increased energy bills. White reflects heat better but it will show dirt more than a black membrane.

So, you should consider the aesthetics if you can see the roof from a window. The color is your decision, just consider the room below the roof, your area’s temperatures, and the energy efficiency.
