What happens here

This step illustrates the critical role of house wrap. The demonstrator shows how, without a protective house wrap, the exterior sheathing is vulnerable to water damage. He pours water onto the sheathing to simulate rain, demonstrating how it can soak in, leading to rot and structural degradation over time. The correct practice involves installing house wrap as a secondary moisture barrier behind the siding.

Goal: Install house wrap to protect exterior sheathing from moisture damage.

Tools and materials

  • Bucket — Holding water for demonstration
  • Exterior Sheathing — The outer layer of the wall, providing structural support
  • House Wrap Tyvek — A synthetic fabric barrier to prevent moisture penetration while allowing vapor to escape
  • Water — Demonstrating water damage

What they say

Hide

the nails are too high, a strong wind could blow these shingles away. Without a rafter or ridge beam, if loads are applied to your roof , it can cause your ridge to sag and your wall to bow. If there is no house siding, your siding may be damaged by water. When installing siding, if the nails miss the stud, they can break out. Most houses don't collapse because of one big mistake. This usually happens when all the errors accumulate. Thank you
