Siding can be vulnerable for two reasons. First, if ignited, combustible siding can provide a path for flames to reach other vulnerable components of your home, such as a window or the under-eave area. Second, if penetrated, a horizontal or vertical lap joint will provide access for flames to enter the structure.
- If you currently have combustible siding, incorporating a noncombustible or low-combustible zone next to your home will reduce the vulnerability of your siding.
- Replacing existing siding can be expensive. There are some less expensive options such as the use of metal flashing.
- Paying careful attention to the vegetation management in the area immediately adjacent to your home will enhance the sidings protection regardless of the material.
