<p>It would be interesting to know if there is some collaboration
between the rack manufacturers offering these new EPDM or peel and
stick legs/ cones/attachment points and roof shingle
manufacturers, and what that conversation is like.<br>

William you and I think a lot alike. I had a job today where \u201cthe
owner was told by a roofing company that those solar panels are
making my roof leak\u201d. This was on an 11 yr old install over new
shingles. We used flashings and added flashing stock anywhere
that was close to a shingle seam (just like always). So instead
of fighting the battle we scheduled to show up at the same time as
the roofer (one of the top 2 roofers in town and the same company
that laid the roof 11yrs ago). Did the leak checks, ID\u2019d the
location, lifted panels and let them go to town. Turns out that
the leak was 3\u2019 away from any of our penetrations and the leak was
at a shingle nail. The cause according to the roofers (lead guy
and manager) was water running sideways from the adjacent gap
between shingles. Their comment-\u201cwe see this all the time on
these 3D shingles on roofs that don\u2019t have solar panels\u201d.
Apparently, \u201cif leaves build up or ice dams up then water shoots
sideways and after a while the nail holes leak\u201d. Their warranty
-2 years! So, there ya go. Crisis averted, solar not the
culprit. But can you imagine how that would have turned out if we
had NOT used flashings?
<div><br>
</div>
<div>We will not be using unflashed attachments. Besides, what
happens when the new guy misses the rafter or what happens when
the rafter spacing changes (we see that a LOT)? Sealed L feet
are a huge step backwards IMO.</div>
<div><br>
</div>
<div>The problem now though is the flashings that I know work
(SnapNRack old style) are no longer available. It seems that
all the new ones rely on a cone with EPDM seal and washered lags
for sealing. Hence the initial reason for this post- what are
you guys using?<br>

question. I am with you in that I prefer that my

to my discomfort is the reality that chemical
solutions are not nearly as reliable as gravity.
Even the best caulk degrades with time, temperature

more old.</span></p>

<p class="MsoNormal">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.</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">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? </p>
