HI Todd;<br>
<br>
That's very interesting. What roof pitch does that happen? I'm
guessing that at a step enough tilt, the frame damage is alleviated?<br>
Also on your tall pole mounts what pole design do you use? I've
tried telescoping type, and guy wires on tall poles.<br>

<p style="margin:0;padding:0;">I have never had good results
with roof mounted pv in our heavy (mount shasta) snow area.
the snow tends to creep down the glass and peel the bottom of
the frame off the module... and then the glass breaks as it
has no support in that area.</p>

<div>Hi all,</div>
<div>We have been doing PV installs for years with L-feet and
silicone without problems ever. Even still, gravity
flashings seem attractive in shingle roofs, to provide a
second level of security, and a more professional install
(at least in perception). But the cost of these systems in
significant in high snow load areas where we often have
L-feet every 2 feet on center, to evenly load the structure
below. In todays costs, the feet could cost as much as 33%
of the panel value.</div>
<div>I'm wondering what other people are doing in high snow
load areas?</div>
<div>Also. I have noticed that there is a flip side to the
risks. We have found that unless you have good quality
shingles, on a preexisting roof, that sometimes the adhesive
sticking the shingles together is stronger than the low
quality shingles themselves - adding risk of trying to shoe
horn flashing in after the fact. Your experience?</div>
