Sorry for not linking to it directly. I meant the simple model like this: http://www.quickmountpv.com/products/composition-mount.html?cur=0" onclick="window.open(this.href);return false;
They end up being expensive even if you are doing 6' spans and get really expensive with 4' spans. I imagine the sealants these days are a lot better than a few decades ago I'm sure so that's good but it'll be very interesting to see how it holds up over the decades. The little custom L flashing that I've seen some people use when directly lagging the L foot seems to be a slight improvement as then there is also some physical barrier.
It'd be interesting to see installations from the dedicated people that were doing installations decades ago and what they used and how it's held up.
Certainly the roofing is going to be in much better condition under the panels.
All I know is growing up in a house that seemed to have a never ending problem with roof leaks from skylights, flat torch down down, and low pitch roofs I've grow to really really hate the idea of having a roof leak
