Built-up roofing or BUR has been around in the U.S. for more than a century. This material is popular in low-slope applications since it creates a continuous sealed surface. On the other hand, roofing shingles aren’t sealed and need a steep roof slope to properly shed water. ——————————————– CONTINUE READING ——————————————–Discover more about this material from a leading provider of roof installation services. What Is Built-Up Roofing?BUR is usually composed of three parts, which are the bitumen material, ply sheets and one or more surfacing materials. The bitumen can be hot or heated so it liquefies during installation. It can also be cold, which is similar to an adhesive. A licensed roofing contractor can spray cold built-up roofing or apply it with a squeegee. This material doesn’t emit toxic fumes during application and isn’t dependent on the weather. It’s also more efficient than hot BUR. The ply sheets of BUR are special fabrics fortified with fiberglass or organic materials. Each sheet is laid over hot or cold bitumen to secure it to the roof. Moreover, surfacing materials from the top layer may be made of small stones of finer gravel. They help in protecting the layers underneath from the harmful effects of the sun and debris. What Are Its Advantages?Depending on the materials used and your climate, a BUR can last between 15 to 30 years. This roofing system is more ideal for warmer climates. Built-up roofs offer excellent waterproofing and ultraviolet protection due to its aggregate top layer. Built-up roofs are also fire resistant and easy to maintain. They are designed to withstand harsh weather conditions. This roofing material also comes with special, high-reflectivity coatings, which help in maintaining pleasant indoor temperatures. It means your HVAC system doesn’t have to work as hard to keep your interior comfortable, reducing energy costs. Turn to Creative Construction Group for your commercial and residential roofing needs.
