[RE-wrenches] L feet no flashing in shingle roof

[jay peltz]

I have had  the opportunity in the past few years to learn a lot about good roofing waterproofing practices according to the national roofers association.

They don't agree that caulk works as the primary means of sealant, which is what you are doing with an L foot.

And given that we have really good off the shelf approved flashed feet, why would you use anything else?

My 2 cents,

Jay

Also some modules are being worked in around skylights where it is unlikely that room would be available for flashings to center over rafters.
