Re: [RE-wrenches] Flashed Footing Requirements

[Todd Cory]

When I was on the roof taking measurements for the proposed array... I found the oatey flashing on a 1 1/2 sewer vent. The metal was still there, but only a few pieces of the rubber were left. It had been leaking down along the pipe into the wall for years. This is what got me to thinking those rubber flashings may not be as great as I had assumed they were. Since we were putting up an array, it was a no brainer to have the aging roof replaced first, along with the flashings. The comp was 20 years old. Todd Peter Parrish wrote: Let’s see. “25 years out in the sun”. Did the roof last the 25 years? If it didn’t, why weren’t the Oatey flashings replaced as part of the re-roof at $4 a pop?   But I digress. All the flashings on a normal, well-designed are UNDER THE PV ARRAY. No UV, no rain, but some extra heat, no doubt. My wag is that Oatey flashings as part of a PV array will outlast most of the roofs they are designed to protect.   Peter T.

I think caulked L-feet is a more long lasting solution to roof mounts. Todd Blair May wrote: Whats wrong with doing it right the first time? Flashing is the only way to insure that you don't have to use that liability insurance & that the install is water tight. I would speak to the inspector & try to work out proper flashings installed in the future & see if he will waive the removal & replacment of the exisiting installs. Welcome to my world where we loose jobs regularly to other installers that do not use proper flashing methods. Yeah it does increase the cost, but the install should have a life cycle of 25 years. -----Original Message----- From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Nick Soleil Sent: Wednesday, June 23, 2010 8:10 PM To: RE-wrenches Subject: Re: [RE-wrenches] Flashed Footing Requirements Who can help:     One of our local jurisdictions, City of Petaluma, is beginning to require flashed footings under all solar arrays.  I think that some flashed footings are better than the Unirac L feet or Prosolar's TileTrac foot, but the flashed footings cost a lot more $, and some flashed footing products seem flawed (less watertight)  They are asking me to uninstall two commissioned systems from last week, and replace the footings with flashed Fast Jacks, even though the documents detailed the penetration method.      I am looking for some good info that supports flexible installation methods, including caulked footings.  Our industry has come a long way from the early days of racking on slotted angle iron with steel L-brackets for feet, but those experiences tend to give me confidence in continuing to use caulked footings.   Nick Soleil Project Manager Advanced Alternative Energy Solutions, LLC PO Box 657 Petaluma, CA 94953 Cell: 707-321-2937 Office: 707-789-9537 Fax: 707-769-9037      yy    _______________________________________________ List sponsored by Home Power magazine   List Address: RE-wrenches@lists.re-wrenches.org   Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org   List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org   List rules & etiquette: www.re-wrenches.org/etiquette.htm   Check out participant bios: www.members.re-wrenches.org       -- Todd Cory KE6SXS toddc...@finestplanet.com Mt.
