Twist in some rafters and water marks

[Sprocker]

Hi all

House is 1930s

A few of my rafters are twisted where they meet the ridge, a couple are worse than others, also i have water marks in the same rafters, alswell as a few others, the roof was replaced by the previous owner in 2014 as it was leaking whick is evident from marks on the ceilings in the bedroom

I've checked the water marks with a moisture reader and it measures 17% which is 2% more that the unmarked timber

Is a twist quite normal for rafters? as I've had the roofer out that replaced the slate on the roof and he seemed all was ok he also thought that the wet marks were just marks and the roof Isn't leaking

I would just like a second opinion on here to ensure I'm not getting mugged off by the roofer

I haven't got pics of the twisted timber yet but have pics of the water marks

Thanks in advance
Ryan

Yes, the timbers do twist because they just had one or two nails knocked in. Regs are much different and screws are now required.

Nothing to worry about with the water marks if they're historic and not new after 2014 when the roof was replaced. When I do roofs, I line through and add timbers to the side of twisted timbers to straighten things back up, I've even planed the tops off twisted timbers.

Thanks Bonni
Do the water marks look just like stains to you?
Thanks

Also I'm unsure if the water marks are new or not as I've only lived in the house for the past 12months
Thanks
