Afternoon all.
We recently purchased a bit of a "do-er-upper". There is an existing extension that consists of 3 x two-brick walls with patio doors and a couple of small single windows. On top of this four wooden beams, spaced 1.5m apart run at a slight slope from the old part of the house down to the "front" of the extension. These have two wall polycarbonate sheeting on top of them forming a bit of a sun roof.
While currently perfectly usable I am keen to do something with the roof section as it is a bit of a ticking bomb waiting for the right storm to go off. Additionally the room is a thermal nightmare, the walls and floor I will fix with internal insulation board.
My original thought was to replace the polycarb with ply/sterling and cover with EPDM or for ease of installation a paint on such as isoflex professional then plaster boarding under the beams, packing in roofing insulation between the internal and external boards.
I then wondered, for sake of not having the roof off if it would be wiser just to use the existing polycarb roof and EPDM onto that? This is already in place and currently just about watertight. A thrid alternative would be to ply/sterling board ontop of the polycarb so save having the existing roof off.
Current options:
a) liquid rubber the existing polycarb roof sheets
b) remove polycarb sheets and lay ply/sterling + liquid rubber.
c) overboard the polybarb with ply/sterling and liquid rubber.
d) something else entirely.
note: in all cases there will be a 4-8 inch space between the external and internal boarding that will be packed with insulation.
I might be miles off the mark, this level of DIY is new to me so forgive my noobism.
Cheers all.
