What upward camber is needed for a flat panel roof?

The appropriate upward camber for a flat panel roof is critical for ensuring proper drainage and structural integrity. An upward camber helps prevent water pooling by encouraging drainage towards the edges of the roof.

Choosing the option that states 6-8mm as the required camber indicates that this range is optimal for achieving the necessary slope without compromising the structural strength of the roof. This camber helps balance the factors of load distribution and water runoff, contributing to the longevity and performance of the roof.

Other ranges may either be insufficient to effectively manage water flow or may introduce unnecessary stress to the structure, leading to issues such as deformation or leakage over time. This makes the 6-8mm range particularly suitable in maintaining both functionality and durability.
