<div dir="auto"><div>We use Quick Mount PV L-Mount but we're switching to IronRidge FlashVue soon. I've seen too many non-flashed solar pool heating mounts work their way loose to trust a mount without a flashing. While PV mounts are different and arguably better, I still prefer a fully flashed method. </div><div dir="auto"><br></div><div dir="auto">That said, I trust the EPDM and Butyl tape gaskets used on some metal roof mounting products, mainly because the surface is different. It doesn't compress the same way a shingle does and it's a clean flat surface. </div><div dir="auto"><br></div><div dir="auto">On my own shingle roof I have installed several QuickBolts to secure some steel cables that hold up courtyard lighting. I'm doing it as a bit of a test because of the lateral stresses imposed on the bolt. Only time will tell how it holds up. For now, I don't trust it enough to install it for a paying client. </div><div dir="auto"><br></div><div dir="auto">Jason Szumlanski</div><div dir="auto">Florida Solar Design Group<br><br><div class="gmail_quote" dir="auto"><div dir="ltr" class="gmail_attr">On Wed, Apr 21, 2021, 10:40 AM Jeremy Coxon <<a href="mailto:jcoxon@sunwindpowerinc.com">jcoxon@sunwindpowerinc.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space">I\u2019m interested in what the group has to say about the trend, by the racking manufacturers, away from the use of flashings for asphalt/comp roofs? We have long used SnapNRack flashings with much success. I especially like the fact that the penetrations are fully flashed and do not rely on sealant. I am NOT a fan of their new raised cone/epdm gasket flashing. There are a number of these raised cone flashings in the marketplace and it\u2019s my experience that they don\u2019t hold up to the test of time and I wonder what the roofing manufacturers have to say about this.<div><br></div><div>I see that Unirac, SnapNRack and others are now offering basically a sealed L-Foot which is essentially where we were 15-16yrs ago and met with a lot of opposition from the roofing industry. Just interested to hear what you guys are using these days on asphalt shingle roofs for reliably dry attachments? <br><div>
