Ultra Violet Light

October 24, 2019

The one factor that is seldom talked about amongst roofing contractors is Ultraviolet (UV) light. UV rays are powerful damaging radiation that is produced by the sun. Ecosystems that are of higher altitude (i.e. our very own Mile High City) are prone to more exposure of this radiation. So why is this important to know about when it comes to your roof? UV light is so powerful that it breaks down chemical bonds altering the chemistry of materials. This means the more sunlight your roof receives the more likely the UV light is to break down its chemistry. 

The majority of roofs that are affected by ultraviolet light consist of flat roofing materials such as: EPDM, TPO, Built-Up-Roofing [BUR], and Modified Bitumen. The UV rays will often eat through these materials allowing water to seep through. Because we are at a higher elevation, UV light has less atmosphere to travel through and there for is far stronger.

How do you protect against Ultraviolet light?

As we mentioned, most roofing materials that are affected by the sun’s Ultraviolet light are flat roof membranes. We recommend using a roof coating to protect your roofing investment and help block out the sun’s powerful rays.
