Retrofit Improvements: Wind Resistant Exterior Cladding

Published Monday, February 28, 2022

During a hurricane or other severe windstorm, exterior wall siding can be damaged or blown off the house, leaving the water-resistive barrier (WRB) as the only protection against rainwater. If the exposed WRB is then damaged or compromised, severe water damage to wall sheathing, wall cavity insulation, and interior wall finishes can result.

Roof overhang soffits and fascia are also vulnerable to wind damage. The loss of soffits can leave large openings susceptible to wind and water intrusion into the attic that can lead to extensive damage and even building failure. The loss of fascia can expose soffit panels to the wind and lead to their failure.
