The uplift loads on a roof can be 10 to 15 times greater
than the weight of the roof.
You must secure the roof from uplift winds so the weight
of the roof becomes greater than the uplift forces caused by
the hurricane winds, and the Fortress 5 will do just that:
Secure the roof.
Roof sheathing will produce a gaping hole and increases
the amount of interior damage to the home.
Damage to the roof will lead to severe water damage and
can lead to significant mold problems.
Protecting the windows and doors from wind-borne debris
is very important in protecting your home. If a large window
or door is broken and is facing the wind, the uplift forces
on your roof may be doubled and it is likely that your roof
will be blown off so protect all openings.
When high winds roll over the edge of a building, it creates
a vortex or suction that is most intense at the corners of
the building.
Winds don’t just apply uplift forces to the roof, they also
create pressures that push and pull on all exposed surfaces
of the house. The winds try to lift the building up, tip it
over, and push it sideways.
 Two forces are needed to blow a roof off: negative and
positive pressure. It is important to protect all openings.
There is enough pressure being applied to the outside of the
home, trying to tear it apart, without the added “help” from
wind pressure from inside.
The roof is the most critical part of the home or building.
You must protect the roof structure to save the home. Also,
water damage can lead to mold damage and at that point the
home is unlivable.
