As with any commercial roof that is poorly maintained, Stadium Drive was losing the benefits of their roofing system. Drains were backed up (due to debris), standing water was present and the roofing membrane was degrading, despite being installed just 10 years prior.
It was evident that the building’s lack of maintenance was causing issues that would eventually result in major repair or replacement. In addition to the presence of considerable debris, numerous drains were clogged (creating standing water), and seams, curbs and wall flashings were in need of attention.
Even more, the white PVC membrane had darkened significantly because the material had never been professionally cleaned. Unfortunately, knowledgeable commercial roof cleaning services are difficult to find, and, this gap in the industry is the exact reason why TEMA Roofing implemented eco-friendly, commercial-grade power washing as an add-on service within their Preventative Maintenance program.
Especially when dealing with a white cool roof system, it’s essential to keep the roof clean and well-maintained. According to Duro-Last (a manufacturer of white PVC roofing), white membranes can reflect up to 86% of the sun’s energy and can greatly reduce energy consumption and costs for a building.
What is a Cool Roof?
Cool roof systems have been around for decades. Their highly reflective surfaces help to deflect solar heat which, in turn, decreases energy use and emissions.
Duro-Last notes that an effective white roof can make building insulation 25 to 50 percent more effective and improve HVAC efficiency by keeping inlet air temperatures 5 to 15 degrees cooler than other roofing systems. Additionally, it can decrease interior temperatures by 15 to 20 degrees during hot months and reduce heat flux.
White PVC membranes can be installed on virtually any structure, including flat, low-slope and sloped roofs and are applicable for any geographic location.
A variety of colors are available (even though white is the most reflective) because a variety of colors can reflect the near-infrared spectrum, which makes up nearly 50% of the sun’s energy.
