Not quite, what you said was that they wouldn’t engage at all. In reality, they did engage, were helpful, and pointed me in the right direction. This was an older guy that designed my roof 30 years ago, we had a half hour chat, just discussing ideas, he couldn't provide me with any calculations...

That was the theory, yes. In practice, the truss manufacturer was actually helpful when I spoke to them last year and pointed me in the right direction. Always interesting when real life doesn't follow forum absolutes.

Well, I never planned to "do it" technically, was more after a detailed explanation and just to see what's possible. I did also discuss this purely theoretically with another SE as a potential "bodge/cheap" DIY approach. The idea was that, because in this house there are supporting stud walls...

I have no idea what you're referring to, that post was regarding @chickenlips saying to contact truss manufacturer and that they are often very helpful. He was right and they were :)

So, a final update to wrap up this truss discussion I originally started last year. Over the past couple of months I’ve discussed my roof structure with several smart people, and one thing became clear: there’s surprisingly little clear information online about fink trusses. You mostly find...

So a quick update to say, I'm still "chatting" to SEs. It seems almost impossible to get someone to chat to, emailed quite few and only two responded, one was clearly an apprentice, didn't really know what I was talking about and tried to sell me telebeams. The other one after couple calls and...

Dude, the only trolling here so far is from you it seems. I didn't expect much at all from manufacturer, not only because roof is ~27 year old but they also changed business in that time and are more of a specialised building merchant now. Still, sent them an email last night and got a very...

You may want to apologise to @chickenlips ,he's onto something possibly good here. Details later.

That would be awesome, I will send them an email but I did check manufacturers, they are still around but looks like they are more of a specialised building merchant now so most likely won't be able to help.

I'm well aware of that. Still, all is well with the velux and installation followed general advice on how to do it.

Correct, not visible in the pic. Fyi, additional rafter is slightly recessed and thicker to eventually allow sheet of ply between rafter for additional bracing and overall strength on each side, ain't there right now because I'm sorting out pir insulation, plus original bracing is still there...

Btw, I'm aware life can change quickly but not planning to ever leave this house so there is that, shouldn't be a problem for me :)

Mitek is the designer, I would imagine them being a big company, they either wouldn't be interested or charge an arm and a leg to do any calculations? Does anyone have any ideas how much something like this might even cost? I guess I can email them and ask. So far I emailed three "local"...

I think the funniest one I've read here was a guy, that removed one of his rafters for a very small velux, think sometime in 2014 and despite the roof being very clearly overengineered to a point of being ridiculous with the adjoining rafter/beams being the size of my leg, he was told they...

Thanks, that at least gives me something to go with to an engineer, finding one is another matter, they are rarer than hens teeth here it seems so might have to look further away. The short webs where they join the bottom of the whole truss do sit on a supporting bedrooms/bathroom walls, they...

There's a diagonal bracing just where the lower left corner of the velux is and there's a horizontal one tying the outer webs. They are there and this wasn't what I asked about. The same ones are on the other side of the roof and there's one at the top of the roof that is nailed to all trusses...

I didn't. Bracing is there, adjoining trusses were strengthened. No need to worry about Velux. I'm well aware, that with e.g. snow there would be significantly more load in there and they would most likely stiffen up. Telebeams from what I understand are mainly there for proper conversions...

Might need bit more than that. Do not go to structural engineer?

Before I go to a structural engineer, I thought I'd ask some questions here. I just finished boarding up the loft which of course took ages to do(30+ hours). Earlier this year I've installed the velux window which helped massively with this job. Of course this is a crappy trussed roof and the...
