Due to all of the discussions at Mueller regarding flashed and non-flashed roof penetrations for the solar racking I asked Texas Solar to go ahead and shoot some step-by-step photos showing how they install the mounting feet.  This is a non-flashed installation.  The sealant they use is Sonolastic NP1 Poyurethane Sealant.  Just as an FYI.....this is the method that I believe all Solar installers in Austin haven been using, with success, up until about a year ago when a few of the vendors started using flashed installations.  Texas Solar Power has been using this method for approximately 15 years with good results......they wouldn't still be in business if their installations leaked.  Meridian was also using this method for about 9 years prior to switching to flashed installations last year.

Step 1 - Drill holes through shingles into rafter and fill with NP1 Polyurethane Sealant.



Step 2 - Allign mounting foot over holes and use impact drill to drive stainless steel lag bolt into rafter.



Step 3 - Apply NP1 Polyurethane Sealant to top bolt heads and top and sides of bracket.



If anyone at Mueller is interested in taking a look at a bracket or anything else please don't hesitate to stop by.
