CA Title 24 Cool Roof


 Because cool roofs save both money and energy,they have become a requirement of California's energy code, the Title 24 Building Energy Efficiency Standards.   Cool roofs have other benefits, too. For building owners they can cut maintenance costs and increase the life expectancy of the roof. And for society in general, cool roofs can even help to reduce the urban heat island effect that makes our cities hotter and produces unhealthy air. 

Environmentally Friendly


There are many environmental benefits associated with TPO and PVC roofing membranes. Notably, the membrane’s high solar reflectivity reduces AC load and energy waste, lowers monthly heating (with insulation) and cooling costs.  These single products are one of the few building materials that can be fully recycled into new products, even after decades of service life.
