If you can stay 8 inches or so from the edge of the roof on all sides, more in particularly exposed coastal areas, the wind loading becomes appreciably more tolerable. We have over 1000 modules installed in the Bahamas over the past fifteen years and as of this day have not lost a single one (knock on wood).</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Daryl</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986">Mail</a> for Windows 10</p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:tom@ecs-solar.com">Tom Lane</a><br><b>Sent: </b>Tuesday, September 12, 2017 10:18 PM<br><b>To: </b><a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a><br><b>Subject: </b>[RE-wrenches] Hurricanes and Wind-loading !</p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>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 <span style='font-family:"Segoe UI Emoji",sans-serif'>🎲</span>) 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.
