House Wrap Basics


As a custom home builder in Florida, some questions we get asked a lot are “When is the best time to build?” or “Should we build in the winter vs. summer because there is less rain?” While the latter question is typically true to our tropical weather, we build our houses preparing for worst case scenario – lots of rain.


After the early 2000s it was discovered that many buildings around the U.S had mold and usually with mold comes rot. A scary adventure for those owning new homes. But with mistake, comes a lesson learned. Building science has since shown that using a house wrap, also known as a water-resistive barrier, and properly installing it enables builders all over to build resilient homes that will last for generations.


Before the wide use of plywood sheathing, drywall, insulation, caulking, and any other product to deter air flow, houses had a less chance of the rot and mold. Why? Because mold and rot doesn’t happen because wood gets wet. It happens because wood got wet, and stayed wet. When you resist air coming into framing, any water is just going to sit there on the wood. This is why house wrap is needed. We use widely known brands, such as Tyvek.


In addition to using house wrap, Sport Nobles Construction also suggests building your home with a roof overhang. It protects the house similar to an umbrella. A steeper roof pitch and wall height are other ways you can design your home to deflect rain during both the building process and the years to come. A steeper roof will pull the rain over the roof pushing it away from the walls. A single story home has less exposed walls compared to a two or three story home.
