Through the years, there have been many roofing materials used for commercial buildings. Although there are newer materials on the market today, many contractors and business owners still prefer built-up roofing (BUR).
What is BUR?
Built-up roofing gained popularity during the 1970s. More commonly known as tar and gravel roofs, this material consists of alternating layers of bitumen and reinforcing fabrics. Together, these create a finished membrane. The bitumen used includes asphalt, cold-applied adhesive, or coal tar. As for the reinforcing fabric, manufacturers use organic or fiberglass mats. For surfacing, manufacturers use different types of materials: aggregates, fiberglass or mineral surfaced cap sheets, hot asphalt, aluminum coatings, or elastomeric coatings.
Roofers in Castle Rock, Colorado count the number of plies in a cross-section to determine the number of plies on the roof. Generally, BURs are fully adhered if installed directly on a roof deck or insulation.
Why Use BUR?
Many contractors and business owners have been using BURs because of their proven reliability. Built-up roofs installed 40 years ago still stand strong today. Here are other benefits of using BUR for your businesses:
- Protection – This type of flat roofing comes in multiple layers of bitumen and saturated felts. These create a water-resistant barrier that ensures protection against the elements for years.
- Energy efficiency – This roofing material comes with special coatings with high reflectivity values. This helps maintain a consistent building temperature throughout. This way, you can save more energy by using heating and cooling systems less often.
- Durability – Built-up roofing has high resistance against fire and strong winds.
