Wall plates out of level

Hi all

Have just stripped the roof timbers off an out building only to find that the flank walls to both sides run out of level by possibly as much as 6 inches from one end to the other.
This is info provided by the bricky who says it will be tricky to level this out with brick work and for it to look reasonable considering the building is in a conservation area.

There will be a facia but no sofit at the eaves as these have to be left open to match the rest of the house

The new roof is a cut one with 7x2 timbers and the ceiling inside is vaulted.

Question is if the wall plates are running out of level does this mean that every set of roof timbers will have to be pitched at different angles?

Have a few ideas to level the plate up but wondering if any of you seasoned vets out there have come across this before and have the solution to hand.

Thanks in advance for any help

You can leave the plates as they are and build the roof squint, i.e. ridge soffit fascia the lot.

Or you can level the plates up and have a normal roof.

The third option is daunting. Build it so the ridge is level and tailor each rafter (rather than do a pattern rafter) including differing wall plate b/m cuts so that the ridge is level and the soffit is level. I'm not even sure that this is doable. It even sounds horrific.

Having differing length rafters is also a mare because this leads to tile coursing anomalies.

The sensible option is to true the plates up. Don't forget that they need to be level AND parallel.

The roof is going to be re slated so the outside face of the timbers will have to pretty spot on.
I did think of what I would call a reducing pitch which involves each set of roof timbers having a slightly diff pitch to keep the roof true.

Thought also maybe getting the timber yard to sort out some firings going from whatever the drop is to nothing over the length of the wall?

Tah for the reply

If the building is old, then put the roof on out of level and out of square and it will look look much better than trying to square things up. Its also a good sign of a tradesperson who can build on the **** and still get it to look like it was meant to be.

Otherwise just but a furring on the plates

I would use the old rafters as templates for the new rafters otherwise
you will have plenty of headaches down the line.

Thanks to all who replied and thanks for the advice

Cant use the old timbers as templates as these have gone, totally rotted and all different sizes of timber ! good idea though shame I cant use it.
I would prefer to pitch the roof on the plates as is but it is going to be a head scratcher

Think ill go down the firings route as we do need to get on with this and the customer is ok with that. we have reclaimed all the slate that came off and those that were pants and fell apart we have a good/old match for.

Thanks for the help guys
