[RE-wrenches] Flashed Footing Requirements

[Kirpal Khalsa]

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.
