What must the installation of built-up roofs comply with?

The installation of built-up roofs must comply with the provisions of the specific section dedicated to roofing in the building code, as well as the manufacturer's approved installation instructions. This ensures that the installation meets both the minimum safety and performance standards required for roofing systems.

Adherence to the manufacturer's installation instructions is crucial, as they provide detailed guidelines tailored to that specific roofing product, which can include aspects like the materials used, layering technique, and fasteners. Compliance with the relevant section in the building code guarantees that the installation meets general structural integrity and safety requirements established by regulatory authorities.

While manufacturer's warranties, fire safety regulations, and local building codes are important, the most comprehensive requirement encompasses both the specific regulatory provisions and the manufacturer's guidance, as it directly affects the performance and safety of the roof.
