Advantages & Disadvantages of Commercial Roofing Type

Commercial roofing systems play a crucial role in protecting a building from the elements, improving its overall appearance, and providing insulation. There are various types of commercial roofing systems available, each with its own advantages and disadvantages. In this article, we will discuss the advantages and disadvantages of the five most common commercial roofing types.

1. Built-Up Roof (BUR)

Advantages:

• Durability: The built-up roof is one of the most traditional roofing systems and is known for its durability. The multiple layers of bitumen and reinforcement fabrics make it resistant to damage from the elements, such as wind, rain, and hail.

• Long Lifespan: A built-up roof can last for 20 to 30 years, making it a good investment for a commercial building.

• Fire Resistance: The bitumen and reinforcement fabrics used in a built-up roof are fire-resistant, providing an added level of protection for the building.

Disadvantages:

• Heavy Weight: A built-up roof can be heavy, making it necessary to reinforce the building's structure. This can increase the cost of installation and make it unsuitable for buildings with limited load-bearing capacity.

• Poor Energy Efficiency: The built-up roof does not reflect sunlight well, making it less energy-efficient compared to other roofing options. This can result in increased heating and cooling costs for the building.

• Maintenance: A built-up roof requires regular maintenance to ensure its durability and longevity, such as cleaning and repairing any leaks.

2. Modified Bitumen Roofing

Advantages:

• Easy Installation: Modified bitumen roofing is relatively easy to install, making it ideal for new construction projects.

• Low Cost: Compared to other roofing options, modified bitumen roofing is relatively low-cost, making it a good option for budget-conscious commercial building owners.

• Low Maintenance: Modified bitumen roofing is relatively low-maintenance, requiring only occasional cleaning and repairs to ensure its longevity.

Disadvantages:

• Prone to Punctures and Leaks: Modified bitumen roofing is not as durable as the built-up roofing system
