Hi all,

I've got to attach a ridgeboard to an existing wall, and the centre of the timber falls on a mortar joint.

Is it ok to use through bolts on the mortar joint, or should I move the holes on the timber?

The height of the ridgeboard can't be moved otherwise the pitch of the roof will change.

Thanks in advance

Paul

A ridgeboard is at the top of a double pitched roof!

There are no walls to bolt it to

Anyway, when bolting timber to walls just move the fixing off centre and stagger them to miss any joints

Sorry Woody I don't know what its called its the timber that attaches to the wall at the top of a mono pitched roof.

The Architects drawings called it a wall plate but you said on another post its not a wall plate.

Thanks for giving me all the advice though Woody on the other posts I do appreciate it :)

It's a pole plate. It's not a great idea to fix into the mortar joint as it's not as strong as the brick. I'd stagger the fixings above and below the joint. Try to get as close as possible to the centres of the bricks.

A pole plate sits across horizontal joists within the roof frame a bit like a purlin. It's a pitching, pitcher or bearer plate
