Retrofit Improvements: Sealed Roof Deck

During a hurricane or other extreme storm, rainwater can be driven underneath the roof covering and cause water damage. During particularly strong wind events, shingles or other roof coverings can be blown off the roof or damaged by windborne debris, leaving the underlayment as the only protection against rainwater. A damaged roof can allow rainwater to enter the building that could saturate attic insulation and damage roof sheathing, ceilings, walls, interior finishes, and household contents. Severe water damage can occur if the exposed underlayment is compromised.
