<div dir="ltr">Kirk,<div><br></div><div>Had the same thing happen to me on a commercial ballasted system installed back in 2004. Had to be moved around to allow installation of a new roof system. Replaced all the ballast in 2017. I'm located in Western NY, thus the same weather you see. The blocks were on a stainless steel pan of which the array was attached to. I've plenty of ideas as to why they broke down but no real evidence. I expect it to happen again. Does make me wonder about the new ballast systems that still call out for the blocks as ballast. Perhaps poly sand bags?</div><div><br></div><div>Christopher</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jun 27, 2018 at 4:20 PM, Kirk Herander <span dir="ltr"><<a href="mailto:vtsolar@icloud.com" target="_blank">vtsolar@icloud.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="blue" vlink="purple"><div class="m_-3312019715009331861WordSection1"><p class="MsoNormal"><span style="font-size:14.0pt">All,<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14.0pt">I have a 6 year old ballasted roof system in which about 50% of the solid cap blocks(16\u201dL x 8\u201dw x 4\u201dD) are cracked and crumbing, some are close to rubble.
