Built-up roofing (BUR) is a traditional and widely used commercial roofing system. It is composed of multiple layers of bitumen and reinforcing fabrics, which are alternately laid down and hot-mopped together to create a seamless, durable, and weather-resistant membrane.

Composition and Layers

The basic components of a BUR system include:

  • Base Sheet: A layer of fiberglass or organic felt that serves as the foundation of the system.
  • Interply Sheet: A layer of fiberglass or organic felt that is embedded in hot asphalt to create a strong bond between the base sheet and the cap sheet.
  • Cap Sheet: A layer of asphalt-saturated or coated organic felt, fiberglass, or polyester that is surfaced with mineral granules, slag, or gravel to provide protection from the elements.

A typical BUR system can have anywhere from two to five plies, depending on the desired level of protection and insulation.

Performance and Lifespan

One of the key advantages of BUR systems is their proven track record of durability and longevity. When properly installed and maintained, BUR roofs can last up to 30 years or more. They are also highly resistant to fire, wind, and punctures, making them ideal for commercial and industrial applications.

However, BUR systems do have some drawbacks to consider. They are heavy and require a sturdy underlying structure to support their weight. They can also be susceptible to cracking and blistering if not installed correctly or exposed to extreme temperatures.

Overall, BUR roofing is a reliable and time-tested choice for commercial buildings that require a strong, long-lasting, and cost-effective roofing solution.

Green roofing systems are becoming increasingly popular as a sustainable and eco-friendly option for commercial buildings. These systems involve the installation of vegetation and growing medium on the roof, providing numerous environmental benefits.

Environmental Benefits

Green roofing systems offer a range of environmental benefits. They can help reduce the urban heat island effect by absorbing solar radiation and reducing the amount of heat that is reflected back into the atmosphere. This can help to reduce energy consumption and lower cooling costs.

In addition, green roofing systems can help to reduce stormwater runoff by absorbing rainwater and releasing it slowly back into the environment. This can help to reduce the risk of flooding and improve water quality.

Green roofing systems can also help to improve air quality by absorbing pollutants and carbon dioxide from the atmosphere. This can help to mitigate the effects of climate change and improve the overall health and well-being of building occupants.

Structural Requirements

While green roofing systems offer numerous environmental benefits, they do require specific structural requirements. The weight of the vegetation and growing medium can be substantial, so the roof must be able to support the additional load.

In addition, green roofing systems require a waterproof membrane to prevent water penetration and ensure the longevity of the roof. The membrane must be able to withstand the additional weight and potential root penetration from the vegetation.

Overall, green roofing systems can be a sustainable and eco-friendly option for commercial buildings. However, it is important to ensure that the structural requirements are met and that the system is properly installed and maintained to ensure its longevity and effectiveness.
