Flat Roof Systems in Florida ​

• Modified Bitumen: A traditional flat roof material with good waterproofing capabilities, but may have a shorter lifespan compared to newer options.  Modified bitumen is a type of roofing membrane made by adding polymer modifiers to bitumen (asphalt) to enhance its physical properties. This modification improves the material’s flexibility, durability, and resistance to temperature fluctuations, making it a more reliable option for roofing systems, particularly in areas with harsh weather conditions. It is commonly used in flat or low-slope roofing applications, where conventional shingles or other roofing materials might not perform as well.

• Composition and Types:

• Modified bitumen membranes typically consist of asphalt combined with one of two types of polymers: SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene). These polymers help improve the flexibility and weather resistance of the bitumen, making the roofing system more adaptable and durable.

• SBS-modified bitumen: This type of modification uses a rubber-based polymer, offering enhanced flexibility, cold weather performance, and impact resistance. It remains more pliable in colder temperatures and can expand and contract with temperature changes.
