My opinion is that if the L foot has enough surface area it constitutes
a flashing, and that large flashings can actually cause more damage to
the roof than they prevent.
I also agree that an attachement doesn't constitute a penetration. I

Hi Ray
Can you elaborate on how a large flashing can cause more damage than it
prevents?
Thanks

Hi William;
First, a sealed L foot is not a sealant only attachment system. It has
quite a bit of surface area beyond the hole just like a flashing, and
has mechanical attachment through the roof to the structure (which a
flashing often does not). I consider an L foot to be a mini flashing fo
Ray:
I have to respectfully disagree with your semantics. A flashing is an
overlapping of roofing materials such that gravity will direct rain and melt
water off of the roof. This is a universally accepted waterproofing method
that does not depend on any sealant material. The concept is as a
"If you place a flat object on top of roofing without an uphill material
lapping over the downhill object, you are not flashing. "
By that logic, an Oatey boot is not a flashing for a plumbing vent on a
metal roof.
Just sayin'...

We did a shake roof, and used a quick mount flashing ( I believe) that
was 18" x 18". According to the directions, we had to use a roofing bar
to pull out the nails to insert the flashing up under the shake.
Missing nails the shakes were not secure on the neds, so we ended up
using sealant to
Not that the names of things matter that much but imho "flashing" does
require an overlapping of some kind. An Oatey boot for a metal roof is more
of a bedded fitting than a flashing. It relies entirely on fasteners and a
sealing membrane whereas flashings rely mostly on natural forces like
gravity

Well, the manufacturer calls it a flashing, but I agree that were talking
semantics here. Flashing, in the code sense, is applied liberally in
practice. The washers on the thousands
It may be helpful to distinguish between exposed-fastener metal roofs and other
roofing systems.
If you’re working on a metal roof that is attached with exposed fasteners, I
don’t know of any practical solution for retrofitting PV without adding more
exposed fasteners. And, yes, the mastic und

gap (UniRac) between the modules so that he can have a dry space underneath the

Any product recommendations or DIY suggestions?
