<DIV><FONT size=2 face=Arial>The flexible flashings you describe are inherently less durable than their non flex cousins. As you are well aware, the culprit is sun or perhaps more accurately, UV exposure. One solar thermal install which was still going strong some 20+ years later had painted those flex flashings and there was no deterioration that I could discern. Choosing the wrong paint could, I am sure, produce accelerated deterioration over doing nothing. As usual, caveat emptor.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Even with tightly spaced modules, there is still a gap (window) for the sun to peek through. How do you inspect those interior flex flashings during the life of the system or roof?</FONT></DIV>

<DIV>Wrenches,</DIV>
<DIV> </DIV>
<DIV>We have been asked to quote a large number of installs on comp shingle roofs for an individual owner who requires Oatey flashing's with a 3" standoff on all installations. </DIV>
<DIV> </DIV>
<DIV>For the past 2 years we have installed the QuickmountPV product on comp shingle roofs and are use to the labor rate quoted for that, my notes from 2+ years ago seem to reflect a 20+% savings in labor by using the QMPV vs the Oatey and standoff method.</DIV>
<DIV> </DIV>
<DIV>Since my notes may not be accurate, I am curious if you are willing to share, what the rest of you have experienced with the labor difference?</DIV>
<DIV> </DIV>
<DIV>Thanks in advance.<BR></DIV>
