Flashing a polycarbonate roof against a brick wall

I have just completed roofing the pergola with polycarbonate and now need to flash the high side against a brick wall. Do I need to cut a channel into a mortar line and sit the polycarbonate flashing into this channel and water proof with silicon?

1. is there an alternative to channeling the wall

2. is silicon the best sealant for this job? Which silicon/product for this external application?

3. what should I do if the poly flashing doesn't line up with a mortar line?

Hi @DIGDIG 

 

I suggest using the 75x75 as this will be more forgiving than the 50x50. If there are any unexpected gaps the 75x75 will have enough size to cover up any unexpected openings.

 

If you need further assistance, please let us know.
