About Modified Bitumen Roofing
Modified Bitumen roofing is an advanced evolution of traditional asphalt roofing, engineered specifically for commercial and industrial applications. It is made from asphalt that has had modifiers added to it to give it plastic or rubber-like properties. The most common types are SBS (Styrene Butadiene Styrene) and APP (Atactic Polypropylene). These modifiers significantly enhance the roofing material’s flexibility, durability, and resistance to temperature fluctuations. Modified Bitumen is typically installed in layers, similar to BUR, but is often lighter, highly tear-resistant, and easier to install on complex commercial roof structures.
Frequently Asked Questions
How is Modified Bitumen installed on commercial roofs?
It can be installed using various methods, including heat welding, cold adhesives, or self-adhering sheets, providing flexibility for different project requirements.
What are the main benefits of Modified Bitumen for industrial buildings?
It offers excellent waterproofing, superior flexibility in cold weather, and high tensile strength to withstand harsh conditions.
Is Modified Bitumen durable against rooftop foot traffic?
Yes, it is highly durable and can withstand moderate foot traffic better than many other single-ply systems, making it ideal for roofs with HVAC equipment.
How long does a Modified Bitumen commercial roof last?
Typically, a high-quality Modified Bitumen roof lasts between 10 to 20 years, depending on proactive maintenance and local climate conditions.
