If you have a corrugated metal roof, we’ve used S-5 CurruBrackets screwed through the metal and into the purlins and then either run the solar rail up and down the roof or install a sub-rack system (with strut or angle aluminum) perpendicular to your solar rail. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Best,</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">August </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext"> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>frenergy<br><b>Sent:</b> Friday, April 29, 2016 6:55 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Goofy roofing</span></p></div></div><p class="MsoNormal"> </p><p>Recently, a customer had a metal roof (not standing seam) installed by a "handyman". Pretty clean installation however for some reason he ran 1X6 stringers across the roof on the 1/2" plywood deck spaced about every 4 feet (as you go from ridge to eaves). Of course the roofing screws are at the stringers. I'm sure he had a <i>great</i> reason for doing so. So now I have been asked to install an array on this roof. You can feel how "soft" the roof is as you walk on it of course because you are walking on air-below-metal for most of the roof. Stringer locations don't jive with possible feet/post locations for rail. I'm usually pretty good at problem solving but I'm accepting ideas.</p><p>Bill</p><pre>Feather River Solar Electric </pre><pre>Bill Battagin, Owner</pre><pre>4291 Nelson St.</pre><pre>Taylorsville, CA 95983</pre><pre>530.284.7849</pre><pre>CA Lic 874049</pre><pre><a href="http://www.frenergy.net">www.frenergy.net</a></pre></div></body></html>
