Hi,
No I haven't done the string line yet as it pouring with rain, I assume the string line has to be set level?
From my measurements the rafters are 20mm out over 6 meters then 6-7mm out over the other 3 meters.
The blockwork, wall plate and ridge board are all level give or take a couple of mm's. (4-5mm measured with a water level)
The wall seems to be parrallel to the existing but even if it was out I can't understand why this would cause the pitch of the rafters to be different, would the birdsmouth just not be further out (or in) along the rafter?
Could someone explain this to me as I don't understand?
As I've mentioned the lower end is going to cause the roof tiles to fall below pitch, by how much I'm not sure but as the tiles are only going to be at 17 degrees anyway I can't afford to loose pitch with them.
Cheers.
