What wind speed requires special building codes to be applied to siding?

The correct answer is associated with 110 mph wind speed, as this threshold is commonly referenced in building codes to ensure that structures, particularly their siding, can withstand stronger wind forces. At wind speeds of 110 mph, the potential for damage increases significantly, leading to the establishment of stricter requirements for the materials and methods used in construction.

These building codes are designed to enhance the safety and durability of buildings in areas prone to high winds, like hurricane-prone regions. When siding is rated for such wind speeds, it means that the materials and installation methods must adhere to stringent guidelines that help prevent failure during severe weather events.

Understanding this threshold is critical for inspectors, builders, and homeowners since adhering to these codes not only ensures compliance with safety regulations but also helps protect the investment in the property and its occupants during adverse weather conditions.
