Loft trussed roof ideas

[katar83]

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.

Yea, let us know how that works out!

You would be better going to the manufacturer who designed the roof in the 1st place.

No, you would not. And it's pointless you repeating yourself.

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

I had a feeling it was a troll thread.

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 helpful reply first thing this morning, effectively saying: "Sure, call this guy in the afternoon on this number, he's one of the guys that designed your roof and he will be able to advise, hope this helps!".
Bonkers, but I will definitely call him and ask so yeah, it appears that @chickenlips was right and you were wrong. Whether he will help or not, is to be seen.

Wasnt trying to troll, genuinely trying to help. I've been a Truss & Engineered joist designer for over 25 years, worked for a number of manufacturers, used Mitek, Wolf and Alpine software. Dealt with remedial details like this and far worse, not once have I sent it out to a SE. Ive always used the software or the Software providers (Mitek, Wolf etc). I would always advise going to the manufacturer 1st when it involves altering a roof truss.

Hope you get things sorted either way.

I'm going with lower triangles sheathed out in half-inch ply, 5x2 timber sistered to the ridge, going as far down as practical, and some sort of timber ridge beam.

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 three emails understood the whole idea so I'm hoping to continue to chat to him when he's back, he has all the details now.
The engineer that designed my trusses seems to be extremely busy or unavailable, called him twice this week and he wasn't at his desk and emailed him and the company and also not heard back.
The part good news is that I found TWO loft conversion companies that have done almost exactly what I suggested and chopped the webs in their conversions and replaced them with a steel beam sitting on the internal wall holding the rafters at the top, the only difference is they just used standard H beam and some rafter ties on both side of the beam(because they had approx half a meter taller trusses) and I want an L shaped beam for maximum space and therefore still need an SE to tell me if a 10mm thick beam with 100mm arms would suffice but looks like these webs can definitely be replaced with a ridge beam. The bad news is that both companies are effectively on the other side of the country.
