We use a stainless fender washer between the lag and L foot both to
prevent a galvanic reaction between the aluminum and zinc plating, and
to seal over the slot in the L foot. It also increases the strength to
prevent the lag from tearing through the L foot in a heavy wind load.
When we tight
Over the years (13 so far) I've installed probably 50-100 systems non-flashed
on comp shingle, and about ten times that number flashed. The early ones were
mostly non-flashed, the later ones nearly all flashed. The switch was around
2005, as I recall. The presence or lack of flashing has had lit
Hi Glenn;
How do you and the roofers deal with Propanel steel roofs? That's
hundreds of penetrations for the screws, with no flashings, and
they depend on just a little rubber gasket. Or how about the lead
head nails on a corrugated metal roof? Roofers t
Glenn, I understand where you are coming from, However
My concern is that flashings could be worse. Unless the flashing design
supports sealant + flashing, it will most likely be worse. I've never seen a
L-foot leak, but I've seem many flashings that rely on gravity leak. An L-foot

We are the McDonalds of roof penetrations. During the last 30 years we have
literally made pincushions of the roof we have worked on. After millions of
unflashed penetrations we have only had one leak. Observing hundreds of Carter
era systems we have never seen a mounting foot leak. Like Sasqua

Hi Troy,
There has been an ongoing debate on the RE-Wrenches list on this
issue for years now. I've personally serviced many
I would have to definitely lean towards using flashings as a default and
have been doing so now for several years. Last project i wanted to use
flashings on and couldn't was in 2010. I couldn't because it was a 10-13

1. I'm interest in a poll of installers who are using flashings vs sealant. Now
that the flashing market has evolved, what are you using today? When did you
switch to flashings (if you did). And why not, if you still prefer sealant.
