Hi

What insulation did you use for the rafters.

Did you consider using quilt such as Actis Tri iso.

I have a 7x2 ridge board. I persume you had similar. How did you strengthen it without the use of steel or lossing headroom.

Did you brace each rafter at the apex just below the ridge board.

What size timber did you use for the cheek walls.

Did you put a 20mm spacer between the roof plate and new joist to avoid snagging the lime plater etc.

Thanks in advance. Simon

Hi

What insulation did you use for the rafters.

to the front storage area I have 100mm kingspan/celotex then silver foil

Did you consider using quilt such as Actis Tri iso.

As spec'd by building control

I have a 7x2 ridge board. I persume you had similar. How did you strengthen it without the use of steel or lossing headroom.

I think i have similar, all interlinked

Did you brace each rafter at the apex just below the ridge board.

Mine was connected front to rear on each rafter as it hung out the rear formed the flat roof joists, BR spec'd Dia 75mm timber connectors that are a bugger to get but have a load left now.
Apparently the loads all work out

What size timber did you use for the cheek walls.

I merged 2 ways.
SE had the 50x50mm and 15mm ply and a few other things no corner post, BUT BR changed it to 100x50mm and 9.5mm ply with a 100x100 corner post for insulation purposes
SE said not strong enough, so I now have 50x50 doubled up on 2 sheets of 9.5mm ply, with the corner post every one happy.

Did you put a 20mm spacer between the roof plate and new joist to avoid snagging the lime plater etc.

yes if lime plaster you will need to chicken wire in the Rockwall

Thanks in advance. Simon

My SE was great but my Draftsman was rubbish, considering he was local seemed to have limited knowledge of our local BR

Hi

Thanks Again.

What do you mean when you say the ridge beam was interlinked. Did they make it a Fitch Beam.

When you said you ran the dormer roof joist through. Do mean you ran it horizontally through from the dormer connecting the front rafter and the back rafter( Stub after cutting) under the ridge board. Then bolting it on using the 75mm timber connectors.

Did you beef up the front rafters.

Did you brace the front rafters back down to the binder beam or did you introduce another purlin.

The structural engineer has quoted me 480 + VAT. to strengthen the roof and design the dormer. Was this close to you.[/img]

Did you consider using quilt such as Actis Tri iso.

There is little if any advantage in using Tri iso, it needs a gap above and below, removing any perceived space savings and it ain't cheap.

Does that help nothing was done to the ridge
The dormer joist you have read a right
The front where made up to 100x50mm ish screwed and glued 50x50
Seem to recall paying a bit more but would need to look back at recept or blog I doing for family etc
