Excellent point, sir. I have looked at quite a few from the attic,
later when doing upgrades, and I haven't seen leaks. But NO, I have
not carefully gone back on every install to confirm. No news is good
news, but that still doesn't mean 100% leak free. Also, I'm
working in a drier climate, where small leaks don't cause big
problems. Actually many of the systems with L feet I've looked at
are not even my own, and (horror) they were sealed with gobs of
silicone. <br>
I'm doing an inspection on a place with hot water and PV on an
shingle roof that is 15+ years old, L feet, no flashings, silicone,
and I will do my best for the list, to get in there and really check
from the attic side. Take photos if I can, and I'll loosen a few
screws to check for any signs of rot around the screw hole. <br>
Really these days my favorite product might be a smallish flashing/
large L foot with butyl tape peel off on the bottom. It would go
under the shingle above, so its an actual"flashing", but not so far
up that you get into the next row of nails, or have to cut the
shingle much. <br>
We also need to really look at the sealant above the flashing and
make sure the shingle above the mount is sealed down properly if
disturbed. I think trouble with shingle roofs starts when wind and
rain can blow back up under a loose shingle. What is the correct
method to seal a shingle back down anyway? Heatgun? More roof
approved caulking? <br>
Chime in ye of more roofing knowledge.<br>

<div class="gmail_extra">Are we assuming "no leaks" because the
home/system owner has not reported any or because there are no
water stains on the ceilings below the arrays *or* are we
actually looking in the attic and seeing that there are
absolutely NO water marks where the attachment points are? <br>
I would think that there is a big difference? But having not
gone back to every install and actually getting up and looking
around <u>inside the attic</u>, would it not be presumptuous
to assume that there have been no leaks?<br>

stainless steel rod hangers straight into rafters,
