You will not see or be able to inspect or repair the transition. The junk at the transition will quickly form a damn and you'll have standing water on your roof - actually standing crap soup - smelling, breeding mosquitoes and probably contributing to early roof problems under an array that will probably need to be at least partially removed and replaced for the reair. Also, after a while, all that runoff stream bedload will settle under the tiles and/or at the transition. Then, having taken everything that washed off the roof - all the leaves, bugs, dead critters, bird crap and who knows what else with it, it will be a great soup, cooking, rotting and probably smelling. Then, it will get at the roof by flowing (or eventually leaking when the non inspectable magic sealant fails) under the shingle/tile transition where it will sit, moist and warm when the sun comes out. It will go under the array, flow down the roof and UNDER the tiles below or near the lower edge the array. Think about where the rain that falls on the roof above the array will go. Outside of some probably bogus save story, there is NO benefit to the owner. He saves time by not needing to replace the tiles and by not needing to be quite so careful (some would say less professional) and maybe a few bucks not spent on broken tiles. !!!!!!!!!!!!!!! The only benefit in such a scheme is to the installer. In my opinion only, but in the strongest possible terms : DO NOT DO THIS. Does anyone have any comments about this approach? 3kw system, 10 panels San Diego, CA Yes. Further my particular tile (see attachment) seems rather intricate (not sure whether that really matters, though). I presume that some sort of sealant might be used on this barrier. My main concern would be wind and rain blowing up under the intersection of the existing tiles and the newly installed shingles. There is some logic and simplicity to this concept that I find appealing after reviewing some of the other panel mounting systems that drill through and/or cut the tile. This seems like it could look a bit funny but the roof is not facing the street so I don't know that it matters. The tiles are removed starting at the downward edge of the roof and the panels are thus placed adjacent to the downward edge. In some cases he says that it actually protects that part of the roof better since some of the tiles are already cracked. Further he says that it, naturally, reduces the risk of tile breakage. He says that if you are going to keep the panels forever then there isn't any need for the tiles and the installation and maintenance is much easier with the tiles out of the way. Hi, I have a quote from an installer that says he will remove my concrete roofing tiles and lay down asphalt shingles while installing the "Quick Mount PV" mounting system under the 10 panels. I presume that some sort of sealant might be used on this barrier.įurther my particular tile (see attachment) seems rather intricate (not sure whether that really matters, though).ĭoes anyone have any comments about this approach?
