[RE-wrenches] Flashed Footing Requirements

Thu Jun 24 12:59:47 PDT 2010

Nick....yes we do cut in the Quick Mount Flashings...we use a hooked carpet
razor blade and the shingles cut easily...The nice thing about the
QuickMount is that it is 12" wide and so even if water could come in the
side it would have a long ways to go to migrate 6" over to the penetration.
In addition we do use caulking in the hole we drill as well as on the lag
bolt supplied with the flashing.....I like how quick they are to install
versus other methods we have tried.....We purchased a "roofing bar" from AEE
and find it an invaluable tool to install the Quick Mount flashings
sufficiently up under the above rows of shingles in case we need to remove
some nails or staples....Its nice cause it eliminates the bloody knuckle
syndrome that was common before we discovered that tool.
If the QuickMount rivet was broken....sounds like a defective piece.....I am
sure Quickmount would replace that for you....we have never had that
happen....I have not used Fast Jacks so have no experience there, but have
used both Unirac 2 piece standoffs and DPW power posts both of which i like
and spec out with Oatey flashings when the roof is being installed new, or
replaced.  We have tried the Thompson Technologies flat jack  and were not
impressed with its flimsy metal plate, which was prone to bow upwards like
butterfly wings when tightend down and also the paint scratched off and the
metal immediately began to rust.
All jobs now get flashed, luckily for us all our competitors are required to
do the same so it keeps the playing field level....
