Siding

Siding is the exterior cladding material that covers the walls of a house, protecting against weather and providing appearance.

Waterproofing and Building Envelope

Why it matters

Siding is not waterproof. It sheds most water, but the WRB and flashing behind it are the real weather barriers.

Where people get this wrong

Siding style affects maintenance, durability, and cost. Vinyl, fiber cement, wood, and engineered wood all have different requirements.

Real-world example

The siding looks fine, but water is getting into the wall. The siding did its job, but the flashing at the window was missing.

Where this hits your build

This affects how your home handles water. Water damage is one of the most expensive problems to fix, and it often starts with details that seem small.

Most people do not just struggle with terms. They struggle with the decisions tied to them.
