[RE-wrenches] Hurricanes and Wind-loading !

[Tom Lane]

Windloading MAPS of Florida depend on how close you are to the coast and
ground mounted versus say on top of a high rise near the beach and how
close you are to the wind zones . The one factor you cannot get away with
is directing clipping panels to metal roofs . You must use a rail that
holds all the panels to the rails instead of the simple metal roof clips .
The one important feature to control wind loads is to use three rails on
two end modules on each end of an array AND 1/2 set extra of mounting
hardware on ALL two end modules . On a raise array on a flat roof you
should X brace the last three on each end . Always stay 3 feet minimum away
from hips , gable ends , valleys , eves and ridges . Use 3/8 "SS
attachments instead of 5/16 " and always hit or attach to trusses and tie
all trusses together with a five pattern ( like on dice 🎲) instead of a
four pattern which skips every other truss . However any Hurricanes  over
175 MPH moving slow will take everything out to the slab  , but if
correctly installed, then when the homeowner finds parts of their home the
panels will  be holding that part of the roof in one piece. GatorTom
