The Basic Mitigation Package focuses on securing the roof system and improving the water intrusion resistance
of the home. Figures 15-16 and 15-17 show two retrofits that fall into the Basic Mitigation Package. One of
the first decisions to make when implementing the Basic Mitigation Package is whether to use Option 1 or
Option 2. The evaluation will identify whether the roof covering needs to be replaced (see Section 3.1.1 of
FEMA P-804 for more information).
If the home is located in a wind-borne debris region, the opening protection measures described in the
Intermediate Mitigation Package should be performed for the Basic Mitigation Package in addition to the
other retrofits. The opening protection measures include installing an approved impact-resistant covering or
component at each exterior window, skylight, entry door, and garage door opening.
FEMA P-804 includes procedures, material specifications, and fastening schedules (when applicable)
to facilitate implementation of the Basic Mitigation Package. Alternative methods and materials are also
discussed to facilitate installation for a variety of as-built conditions.
