Counter-pressure method and apparatus for protecting roofs against hurricanes

An apparatus for counter pressure roof protection against windstorms, comprising:

• a window shutter panel including a porthole therethrough, adapted to be mounted over an outdoor side of a window opening of a house;
• and
• at least one flexible flap member operably attached to an outer surface of the window shutter panel for selectively closing the porthole, thereby permitting outward air flow from an indoor space through the porthole of the window shutter panel to outdoors when the window shutter panel is located at a lee side of the house, and preventing inward air flow from entering the indoor space through the porthole of the window shutter panel when the window shutter panel is under wind pressure, whereby the indoor space is depressurized during windstorms to counteract an uplifting force on a roof of the house induced by windstorm.

An apparatus for counter-pressure roof protection against windstorms, comprising:

• a window shutter panel adapted to be mounted over an outdoor side of a window opening of a house;
• and
• a plurality of strip flap members, attached around a perimeter of the window shutter panel for selectively closing a gap formed between an inner surface of the window shutter panel and the outdoor side of the window opening when the window shutter panel is mounted over the window opening and spaced apart from the window opening so that inward air flow through the gap is inhibited and outward air flow is permitted, thereby permitting outward air flow from an indoor space through or around the window shutter panel to outdoors when the window shutter panel is located at a lee side of the house, and preventing inward air flow from entering the indoor space through or around the window shutter panel when the window shutter panel is under wind pressure, whereby the indoor space is depressurized during windstorms to counteract an uplifting force on a roof of the house induced by windstorm.
