In The Middle Of Attic Conversion


Recommended Posts


If you start chopping them out the roof may sag..the loft conversion's i have seen done have had to have a RSJ steel beam from one gable end to the other before you cut any support's out..

They also take the bounce out of the bedroom ceiling..i would get a builder in mate to check it out..the last thing you want is the roof sagging and allt the plaster on the bedroom ceiling's cracking..

thats exactly what will happen.ceiling nails will pop and plaster crack,i would try get a beam of some sort in finch beam would be handiest,two 9x2s with a 18mm ply in between,then you can run a sub floor in and no pressure will be on your ceilings.you build your walls off the beam and that strenghtens the roof also.then you put in collar ties on.then you can do your cut out.

if you continue the way your going you will have problems in the future

looking at the picture, they look like trusses and that beam across the middle doesn't look big enough to carry a roof mate, they are made like that for strength mate, i think you should have a perlin set in place before you start chopping any timber :thumbs:

you need a rsj on each side just above your perlins that will transfare the weight on your roof onto your outer walls. it needs to be rested on a pad stone and have a minium bearing of 100 mm on each padstone. did you double up your ceiling joists? which is your new floor joists this takes the spring out them provided theyre running from the outer wall plates and onti the walls below they might need a couple of bridgers in too then your floor boarding. you ned to case your rsj in plasterboard for fire protection or buy fire resistant paint to apply ti them and also double up your roof rafters thats carrying your roof windows to strengthen them up too. good luck :thumbs:
