Built-Up Roofing (BUR)
BUR roofing has been used for decades and is still a common flat roofing system in Los Angeles. It is made of multiple layers of asphalt and felt or fiberglass matting and is topped with gravel or stone. BUR roofing is durable and long-lasting but can be heavy and difficult to install.
Pros:
1 . Durability: BUR roofing is highly durable and can withstand various weather conditions, including extreme heat, cold, and heavy rain. It is also resistant to UV rays, which helps to prevent cracking and fading. 2. Low cost: BUR roofing is relatively inexpensive compared to other flat roofing systems, making it a popular option for commercial and industrial buildings. 3. Easy to repair: BUR roofing is easy to repair, and damage can be easily patched by adding additional layers of felt and asphalt. 4. Fire-resistant: BUR roofing is fire-resistant, which can provide added safety for commercial and industrial buildings.
Cons:

Shorter lifespan: BUR roofing has a shorter lifespan compared to other roofing options, such as PVC or TPO. It typically lasts between 10-20 years, depending on various factors such as weather conditions and maintenance. 3. Odor and fumes: BUR roofing can emit strong odors and fumes during installation, which may require additional ventilation. 4. Environmental concerns: BUR roofing is made from petroleum-based materials and may not be suitable for those looking for more sustainable roofing options.
