Roofing Advice Needed: Fitting EPDM under tile cladding without removing all tiles?

[Diyfail321]

Hi everyone,

I’m replacing my garage flat roof (stripping the old felt, replacing the OSB decks, and installing a new EPDM rubber roof).

My main challenge is at the house junction: the exterior brickwork above the flat roof is covered with nailed-in wall tiles/cladding.

Is there a practical way to properly tuck and seal the EPDM membrane upstand into the wall without having to strip all the wall tiles off? (See attached photos for context).

Any advice on flashing details or workarounds here would be greatly appreciated!

Carefully take the first two (or three) rows off to access the upstand area.

When refitting, either leave the top row unnailed, or use a small spot of no- nails adhesive on the back to hold them.
