Modified Bitumen is a very durable product, especially in high traffic areas and especially when combined to smaller roof areas with a high density of service equipment. The flexible nature of the "modifiers" allow owners to select a roof that is a thicker product and more resistant to building movement and metal-to-membrane interfaces than a BUR system.
Modified Bitumen & Built-Up Roof Systems
- North American offers cold applied (adhesive) anchoring when installing a Modified built-up roofing system. Cold applied Modified Bitumen installations means higher quality, as well as ensured health and safety.
- North American always specifies a multi-layer approach due to quality issues which preclude us from offering a sufficient warranty on single layer MB roofing systems.
- North American typically uses a base layer of fiberglass reinforced topped with a polyester reinforced layer. This yields a strong, more puncture resistant and warrantable roofing system.
