A built-up roof is a terrific alternative to shingle roof. However, the resilience and insulation properties of a built-up roofing depend heavily on the type of raw materials utilized. Hence, it is important to conduct extensive analysis and ask your roofer about the raw products prior to the building begins.
Built-up roofing, likewise called BUR, is the most common roof product utilized on low-slope roofings. It is composed of rotating layers of reinforcing fabric and bitumen (asphalt) and is finished with a top layer of aggregate, such as stone or gravel. BUR is chosen for low-slope, or “flat,” roofs because it produces a constant sealed surface area.
Built-up roof is nothing new. The concept has actually been around for over 100 years, although the product and its installation definitely have developed throughout that time. Modern built-up products include a stiff insulation layer for improved energy effectiveness.
The only obvious drawback of a built-up roofing system is that it is relatively more expensive than shingle roofing and needs more effort and time to develop. However, the benefits offered by built-up roof are well worth the additional financial investment of cash, effort, and time.
Water pooling is a small issue that can cause huge problems down the line. Inspecting your BUR roofing system after strong weather condition (to check for water pooling or other problems) is a terrific preventative measure.
Gone untreated, your commercial roofing system can break or leak, which can encourage soft spots and other warping problems, like waving, undulations and blistering.
