Just thinking the end doesn’t have space to do a full ‘W’ as the wall on one side joins the truss high up. The blue lines show the length of the trusses. The circle shows the top of the external wall that they sit on.

Looking at that link there is a lot of wood going everywhere that my roof doesn’t have, lol. Basically the attached picture? Do you attach plates to connect all those piece of timber together such as...

Thanks but that’s probably beyond my DIY skills, understanding how to best join and angle the beams etc. Have to say it’s confusing. The construction boss that had a look has advised doing what I’m proposing with a simply cross beam, suggesting that it would prevent any potential, future...

No, the initial issue with the one truss wasn’t really an issue. It did flag up another issue at the end of the roof which had led onto these questions. Sorry if it’s a bit confusing. There are no ‘Ws’. It’s a strange design as it’s a semi bungalow. Most trusses are supported with a beam holding...

Lol, I can only go by what I’ve been informed and by what has happened to the trusses already, i.e. they’ve sagged/settled a bit. To me it makes sense as bracing them will stop them moving apart further in the future. I know it shouldn’t be necessary but it’s not been put together particularly...

Everywhere I’ve looked says you must not drill into top chord trusses. Have I understood this correctly that you say it’s fine to do that?

Ok thanks. I don’t know what you mean by a collar but the trusses weren’t particularly well put together at the top. The cross beam holds everything together better. So, 10 or 12mm coach bolt, one of these...

The purpose is to add structural support. It isn’t critical but the end of the roof has been put up badly. It looks like they just added a few ends on. I’ve been advised that it would ‘help’ in the event of heavy snow and for long term durability. Im more than happy to drill a hole and put a...

Perfect, thank you. Lastly, would I be right in thinking that ‘A’ would be better screw placements than ‘B’?

When you say predrilling do you mean using a pilot hole? I don’t have an impact drill so would a small pilot hole be appropriate, eg 2-3mm? Screwfix have these 5x80 with torx head to make screwing easier. Only down side is the countersunk head. What do you think about these or is it best to...

Thanks. I have read several comments including from your good self way back in 2013 suggesting nails over screws for this purpose. If screws are ok is there a rule to the correct size? I’m thinking 6 x 90 coach screws as the two pieces of wood are both 2inches each...

Following on from the advice from my other thread I’m am needing to add some supports similar to a few that’s there already (see red line in picture). I have some c24 4x2 which will be used and was intending to screw them in until I read that screws are less favourable and nails should be used...

Thought I would give a quick update. I have had a reputable construction/roofing company have a look. Their report is pretty much what has been said here. It’s been badly made but the bottom line is it’s not going anywhere now. The ‘broken’ joint was a bodge when they built the house as they...

Not that I can see. I’m guessing there is some reason that haven’t had in vertical supports so I was thinking about adding 45 degree supports against the wall and each other such as this. Any thoughts as to whether this would be a good idea?

Oh, no. I didn’t notice that at all. While it does look slightly exaggerated it is noticeable. I looked up in the loft at that area and it is constructed differently, probably because of the lack of roof on the other side (see my previous post). I’m hoping that the ‘sag’ is due to the different...

Yeah, it is an odd one and agree about bracing it.

This is where the beam lies. To me it makes a bit more sense why they have had to put it in wonkily.

I know, it is a bit of a mystery as to what is going on. Could the slightly odd/off spacing be due to the velux window on the other side? The metal is torn but I can’t see how it would have been torn from a force after installation as the lower beam is true to the wall. I can only think that...

Looking at it again the beam coming up is perfectly square the the walls. The attached point in the apex is not in line. I hope that makes sense as I can’t get a good enough photo to show it so have done a quick and crude drawing. As others have suggested I don’t think it has broken. I think...

I’m guessing the reinforcement is there as that is the corner that gets the wind. It would be a coincidence if it was for any other reason.
