Waterproofing for Roofs in Saudi Arabia: Full Guide

Roof Waterproofing in KSA: Beyond Just Stopping Leaks

In Saudi Arabia, waterproofing is not just about keeping the rain out; it is about protecting the structural integrity of the concrete from thermal shock. The extreme delta between day and night temperatures causes concrete to expand and contract, leading to micro-cracks that allow moisture to penetrate the rebar.

The Two-Step Approach: Water & Heat

A professional roof system in the Gulf must be a "Combo System."

• Waterproofing Layer: Utilizing BSCO's advanced bituminous membranes or liquid-applied polyurethane.
• Thermal Insulation: Essential for energy efficiency under Saudi Building Code (SBC) requirements.

Selecting the Right System

• Exposed Roofs: Require UV-resistant coatings like Polyurethane to prevent degradation from intense sunlight.
• Inverted Roofs: Where the insulation sits above the waterproofing, protecting the membrane from mechanical damage and heat.
