[RE-wrenches] Flashed Footing Requirements

[Nick Soleil]

I did a cost analysis between the TileTrac footings vs E-series Fastjacks with Oatey Solar Flashings, and found that the cost was less than $2 more.  That finding is encouraging me to default to FastJacks for my standard penetrations. 
Kirpal:
    Do you cut in the Quick Mount flashing, if not, it really isn't a flashing, because water can blow in the sides.  I tested a Quick Mount flashing once, and when I removed the lag, the stainless steel rivet that attached the sheetmetal to the base was broken/ seperated.  This made me concerned that Quick Mount was not a great solution.  Also, the QuickMount is $10 more than the FastJack with Oatey method.

We are very impressed with the Quick Mount flashed brackets......they are a solid attachment with no chance at leakage if installed properly.  Easy to install, small number of tools required, and good quality.  Oregon rebate programs (where we are based) are requiring all roof penetrations/attachments to be flashed.  even though it is a bit more expensive, the flashed penetrations allow us to sleep well at night.  we have never had a call back due to a leak with a caulk and L foot attachment, but i would expect them to fail before the flashed attachments, and in the ~30 year life expectancy of the solar modules and possibly roof, I dont have that much confidence in caulking lasting that long, even though caulking hasn't failed in 10 years, I find it hard to believe that it will last 3 times that long.....i like the idea of all components having a similar life expectancy.
