This is why you need water proofing!
• In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment.
• The roof covering materials, siding, foundations, and all of the various penetrations through these surfaces need to be water-resistant and sometimes waterproof.
• Roofing materials are generally designed to be water-resistant and shed water from a sloping roof, but in some conditions the roofing must be waterproof.
