So,
Just bought a house - That was the easy bit.
The surveyer pointed out that one of the purlins had slipped slightly and that it was probably historic. He recommeded some suplemental additional supporting of the purlin corners using brackts.
Went up in the loft on the weekend to have a good look and it appears that the purlin has escaped its socket in the wall. The remaing 3 corners are also not brilliant and it looks like the original roofer cut the purlins too short.
Slipped socket
This has led to weight bearing on the cross braces and joists and it is bowing significantly.
Also it looks like the whole roof has spread by about an inch as the supporting timber on the opposite side has twisted by about 45 degrees. This shows the effect, the timber on the right is flat and sqare at 90 degrees on the rafters whereas the one on the right is at about 45 degres probably to the slipped purlin.
So - comments/suggestions/recommendations please.
Currently I have placed a couple of 2X3 timbers to provide additonal bracing to the slipped corner but this is temporary only.
Ideally I would like to jack the purlin back into its original place as the ridge tiles are not sitting flat. I realise this may not be possible though.
Also the purlin is split lengthways for about 1/3 of its length due to the weight bearing on to it.
Solutions i can think off are
1) Place additional cross bracing towards the apex on the roof - ala - loft room conversion. This will future proof the option of making a loft room in tthe future.
2) place 4 X hanger brackts at each purlin corner to prevent further slippage
3) Place vertical timbers supporting the purlins.
4) put head in the sand and leave as is.
