Trusses

[pilsbury]

I feel your novice pain. Suppose to low a pitch can be corrected easier with furrings....Experience comes after buggering things up a few times. I too will be embarking on my first roof soon - partly matching into an existing roof with gables, hips and valleys. I don't want to gain my experience by buggering that up....

Let us know how it goes!

I will do mate. I don't mind cocking things up but with this one it's the fact that I could have 700 quids worth of scrap wood on my drive and no way forward if I've got it wrong. I had originally wanted to do a cut roof as I just prefer the concept but the ceiling span is so big it would have been a pain.

deleted another bad idea Good Luck anyway.

We put them up today and happy with the pitch, slightly on the low side but I'd rather that than have it too high. Bloody glad I double checked the measurements and did my own trig calculations or it would have been a disaster.

Your diagonal bracing should continue down to the wall plate. Add another short length (across say four rafters) and fix it along side the existing and down to the WP.

Yep, knew I'd got that wrong as soon as I did it. I guess you don't brace to the last truss then, in order to hit the wall plate. Bco didn't spot it, but yep I'll sort it exactly as you say.

Correct.
The truss drawing usually shows the diagonal bracing going all the way down to the WP.
