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

      48" brake from china already arrived.

      came to the realization that im dumb as hell and can't make a singular piece pan for a 48" window with a 48" brake hahahah

      i'd have to make separate end dams, or do two pieces with a seam in the mid

      but hey, at least i have another tool in the garage.

    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
