Hi all, im due to have work started on my new roof tomorrow. the house is a 1930s semi. been there couple of years now, the membrane is not breathable so moisture collects on it and drips in to the floor and causes the wood from the roof to get wet and its currently looking like it has mould all over it. house still has original tiles so having all those replaced aswell. i am hoping once the new roof and membrane is on this should stop any damp problems. i havnt really spent any time in the loft but ive just been up to clear some stuff out before they roofers turn up tomorrow and i have noticed that my purlins are supported by four bits of wood and two of these are just proppped under and not screwed in or fixed. they seem to be under quite a bit of stress and are on a slight angle so this is causing me a bit of concern.
i am also planning on having the loft converted once the roof is done. it was partly been done by the previous occupants its mostly boarded put with some really old crappy looking fibreglass under. what are people onions on me taking this fibreglass put completely? will i need to replace it or will it be best leaving it out so the house can breathe better and heat can circulate to the loft?
