Roof waterproofing in Saudi Arabia
Start with water paths, detailing and drainage before choosing the membrane.
Common leak points
Drains, roof-to-parapet junctions, equipment bases, pipes, cracks and movement joints are common failure points. A new membrane will not necessarily solve poor slopes or inadequate drainage.
Code context
Saudi Building Code requirements address weather protection and waterproofing in relevant building assemblies. Use the current official code and project-specific design requirements for actual work.
Choosing a system
Liquid membranes can suit complex geometry; modified bitumen or TPO/PVC can suit larger flat areas. Compatibility with the substrate and details is more important than the material label alone.
