Jay - I'll add one big point to working on tiles - make sure you check the condition of the underlayment before starting work. Tiles can last for a long time, but the underlayment (felt paper) on older tile roofs starts to become brittle and disintegrates. Water during heavy wind storms works its way between the tiles and gets under the underlayment if it isn't intact. Vent pipes, skylights, and roof transition points can start to leak. Removing and replacing tiles in order to install the PV system can disturb the fragile underlayment and cause problems. We've run into such issues and stay away from self-waterproofing tile roofs that are older than 10 years or that show signs that they weren't installed properly in the first place.

Quickmount and EcoFasten both make similar products: http://www.quickmountpv.com/downloads/datasheet/QMPV-datasheet-QMTRM-TileReplacement-web.pdf http://www.ecofastensolar.com/store/pc/viewPrd.asp?idproduct=30#.WUvcYWjytaQ There are several advantages of this replacement type system. Check 'em out!

And have an install that does have them. Something like a Striata type. Wondering what recommendations folks have for how to mount with them. Its not a large system currently only 6-9 x 280 60 cell modules. Probably doesn’t make sense to remove/reroof in that area. And the roof can handle the weight without removing the tiles. thanks in advance, Jay Peltz Power. _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
