    I am currently replacing my roof including new rafters, done as part of a loft conversion.

    Purlins removed and new structural kneee walls ro replace them.

    It's is a semi detached bungalow.

    The issue I have is that I now have straight rafters and the neighbours rafters on his side of the party wall are sagged (bowed) in the middle of the span.

    It's 40 mm lower than mine at the mid span the purlin must have moved on the supporting wall in the last 92 years it's been there.

    It's correct at the ridge and correct at the wall plate.

    How do I get over this with out having a huge kick in the roof.

    Allready was going to have a small kick due to new 50 X 25 battens being used vs his 38 X 19 or imperial equivalent.

    I can only think of using the power plane to replicate the bow over the first 2/3 rafters to blend it over a longer distance but this will reduce the size of the 2x6 being used. Not sure if bco would be happy if he notices

    It's under a tarp at the moment so will get a picture if it ever stops raining.
