flashing tape + liquid flashing in lieu of solid metal for brick veneer window sills?

cs55 | Posted in General Questions on

have replaced all of the windows in my house and only 1 window has any visible water damage, which is also the only window without any overhang.

https://i.imgur.com/COPbcs5.jpeg is what i was going for, but going with metal flashing will be troublesome.  none of my exterior brick sills have any flashing like in that photo, when i talked to some masonry  contractors that focused on new construction that photo was greek to them : )

how dumb or ill advised would it be to do that, but with https://www.masonrydirect.com/products/york-304-stainless-steel?variant=39454067130439 or some other tape, use two different pre fabricated metal flashing https://i.imgur.com/iKMpyB9.png , use the L flashing as a back dam, and the drip edge under the brick sill.  then tie it all together with liquid flashing.

better than nothing? waste of time ? if not a terrible idea, any suggestions for 12″ minimum tape? that stainless steel tape seems alright.

    Call a local hvac shop and have them bend you a custom flashing piece out of single piece. They will do exact dimensions. If first hvac shop can’t ask who in area has 10’ brake

    yea, i know thats the best way :/

    my main concern was being able to get the measurements precise enough with the window still installed

    for the cost of a roll of tape i could get a basic 48 inch metal brake, that might be my best option. its a 48" wide window so if i went with my liquid flash idea then id eat up $40 worth of liquid gold just for the pan.

    if i take out old window, measure, provide measurements to shop then im without a window for a bit unless im lucky and can get one same day.

    buying a brake seems like an okay idea.

    what metal do you guys usually use? if i went with stainless steel what # would be best for outside exposure with mortar contact
