    Birds mouth seat cut overhang

    apologies for bringing an old(ish) thread back to life, but does this look okay or...? I've emailed this sketch to my BCO for his input. The house has a new cathedral ceiling and originally, the roof had lightweight cement tiles. I want to install CUPA H3 Slates which work out around 49kg per...

    No, I live in a recently built (2010) house approximately 50 metres away from this one. The house being renovated is my old family home

    How to support existing rafters with a new ridge beam?

    decided to go with short collars screwed to the rafters, gap the same as the thickness of the GLULAM (115) then pushed the beam up to meet both collars and rafters at the same time. Only hope the BCO is happy with it, inspection next week. Why do SE's make things so awkward, like, wanting me to...

    How to support existing rafters with a new ridge beam?

    The SE spec'd 15mm Ply Gussets fixed by 14 nails per member. I'll be using 18mm OSB3 fixed with expanding PU and about 14 nail fixings per member. I'm hoping when he says Ply - OSB3 would do the same job. The rafters have the extenders fitted now, the beam *is* going up and just touching the...

    How to support existing rafters with a new ridge beam?

    I was gearing up for birds mouth cuts with the trusty self levelling laser this morning then I spoke to my SE. After I told him I could either plumb cut with heavy duty L brackets into the beam or birds mouth the rafter extender pieces to the GLULAM (115x495x6355), I asked him what is...

    How to support existing rafters with a new ridge beam?

    I did see them, priced them up, £500 + Veg and Tatties for 26 of them. They want the angle of the bracket slope, not roof pitch. Thought they'd be able to work that out if I gave them the pitch. I can get one to fit, 105mm tall (SAE-250X). Now I want to birdsmouth the 45x95, am I right in...

    How to support existing rafters with a new ridge beam?

    Morning! From inside wall to wall is 7.4m, walls are approx 270mm thick, 2 x block plus cavity, it's a good span. I've had a look at Simpson website and Cullen's as well. If I go for the plumb cut of new rafter extenders into the beam, could I just use Simpson A35 brackets? I bought a load of...

    How to support existing rafters with a new ridge beam?

    I'd like to bring this thread back into life. Doing a full house renovation and installing a 115x495x6355 Glulam beam. Original rafters are 5x2, I want to get rid of the rafter (ceiling) ties and the collar ties and have the Glulam installed right up to the original rafters. I'm also going to...

Back to block, ground floor lifted and void filled with 75tn type 1 for slab/PIR/UFH and screed. Now onto the roof. Half the house will be open plan, approx...
