BACKGROUND

INSURED PERILS WIND EARTHQUAKE FLOOD (MAINLY GOV.) WINTER STORMS HAIL FIRE INSURANCE: “TEN MOST WANTED SOLUTIONS” WILL BENEFIT EVERYONE REDUCTION OF PHYSICAL VULNERABILITIES

CONTRIBUTIONS OF NATURAL HAZARDS: TO RECURRING LOSSES CONTRIBUTIONS OF NATURAL HAZARDS: TO RECURRING LOSSES EARTHQUAKES: GREATEST SINGLE- EVENT POTENTIAL LOSS OF LIFE WINDSTORMS, EARTHQUAKES, AND FLOODS: ANNUAL ECONOMIC LOSSES ARE DISTRIBUTED NEARY EQUALLY BUSINESS INTERRUPTION FROM ALL HAZARDS CAUSES MAJOR ECONOMIC LOSSES EARTHQUAKES: GREATEST SINGLE- EVENT POTENTIAL LOSS OF LIFE WINDSTORMS, EARTHQUAKES, AND FLOODS: ANNUAL ECONOMIC LOSSES ARE DISTRIBUTED NEARY EQUALLY BUSINESS INTERRUPTION FROM ALL HAZARDS CAUSES MAJOR ECONOMIC LOSSES

MOST WANTED SOLUTIONS SEVERE WINDSTORMS: “HURRICANES”

MOST WANTED SOLUTIONS METAL EDGE FLASHING COVERINGMETAL AND LIGHT WEIGHT CONCRETEROOF ASSEMBLY: ABOVE DECK (COVERING) AND DECK (METAL AND LIGHT WEIGHT CONCRETE) FASTENERS:: TYPES AND SPACING WINDOWS AND DOORSOPENINGS: WINDOWS AND DOORS

FOR SEVERE WINDSTORMS (Hurricanes, Typhoons, Cyclones) HIGHEST PRIORITY ARE MEASURES THAT PROTECT ROOFS AND BUILDING FACADE OPENINGS. RESEARCH ON WINDOW COVERINGS SHOULD BE ACCELERATED.
