Here is a devils advocate question for everyone (*including myself*) who is claiming "no leaks after x-years".
Are we assuming "no leaks" because the home/system owner has not reported any or because there are no water stains on the ceilings below the arrays *or* are we actually looking in the attic and seeing that there are absolutely NO water marks where the attachment points are? I would think that there is a big difference? But having not gone back to every install and actually getting up and looking around *inside the attic*, would it not be presumptuous to assume that there have been no leaks? *Benn Kilburn * CSA Certified Solar Photovoltaic Systems Electrician, SkyFire Energy Inc 6706 – 82 Ave NW | Edmonton, AB | T6B 0E7 P: 780-474-8992 | F: 888-405-5843 | www.skyfireenergy.com [image: email] <b...@skyfireenergy.com> [image: facebook] <https://www.facebook.com/SkyFireEnergy> [image: twitter] <https://twitter.com/SkyFireEnergy> [image: linkedin] <https://www.linkedin.com/company/283735?trk=tyah&trkInfo=tarId%3A1408655033432%2Ctas%3Askyfire%2Cidx%3A2-2-5> [image: google] <https://plus.google.com/+SkyFireEnergy/> [image: SkyFire Energy Logo_horizontal] On Wed, Aug 26, 2015 at 1:52 PM, <m...@seesolar.com> wrote: > I remember the "early days" of installing, which for us was early 1990's. > We used stainless steel rod hangers straight into rafters, which left us > with 4" threaded rod sticking up out of the roof.
