Window head flashing
I am preparing to install some windows. If I want to do best practices – I am assuming I should have end dams fabricated into the window head flashing. My questions are –
1) what is the typical height of the end dam – i.e. a 1/4 inch?
2) how far over the corner of the window should the flashing extend on each side of the window?
Thanks for your help.
