I will say that I loose jobs due to the additional cost of components & labor to install flashings. It is very frustrating having my local competition continue to squirt the L foot n go......<div>Our society, despite long winded explanations to a potential client the benefits of flashing, still are driven by the short term $$$$ savings despite the long term liability & cost of roof replacements.</div><div>The other advantage of flashing is the improved long term output w/ the additional air circulation under the modules.

What I have seen is that a fastener is not considered a "penetration." The argument used frequently is that the thousands of screws that attach an exposed fastener metal roof are not "flashed." The argument goes that the codes sections cited be Andrew are intended for large openings like roof vents and plumbing vents. If the screw occupies the space of the "penetration" and is further sealed with sealant or a gasket, there is no flashing required. You could extend this argument to shingle nails that go through the "roof plane" depending on how you define it.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Don't kill the messenger - I'm just pointing out the logic/argument made against the requirement for flashings.</div><div class="gmail_extra"><br></div><div class="gmail_extra">I'll reiterate that my vote is to flash!</div><div class="gmail_extra"><br></div><div class="gmail_extra">Jason</div><div class="gmail_extra"><br>

I’ve always been of the opinion that simply crushing some sealant/gasket onto an asphalt shingle work fine at first (the test data from roof-tech is impressive), but would be an issue 10+yrs down the road (thermal expansion movement, freeze/thaw, etc). I can make a good waterproof seal at first by just slathering some butyl/silicone to an L-foot and cranking it down on the shingles, but that practice really disappeared 8+yrs ago.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Maybe consider this a Poll: (to flash, or not to flash) <u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">With Regards,<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Daniel Young, <u></u><u></u></p><p class="MsoNormal">NABCEP Certified PV Installation Professional<sup>TM</sup>: Cert #031508-90<u></u><u></u></p></div></div></div></div></blockquote></div></div></div><br></blockquote></div></div></div>
