re-roofing

[chickensalad]

hi all
need some advice about my utility room that i'm re-roofing.The problem i have got is that as i live in a semi, our roof is joined with next door one continuous roof all the way through the boundry, same pitch no step up or down. the neigbhour has marley tiles as i did till i took them off and wanted to replace them with rosemarys to match the rest of the house. What i can't get my head around is how the rosemarys butt up to the marleys.I realise there will be some lead in there somewhere and have done soakers and steps before but clearly not encountered this previously.any advice would be appreciated
