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?

thw roofers should sort all them traps out for u as I assume they are proper guys and not some cowboys. what roof tiles are on there currently as most old tiles are good quality ones and usually it's better to have just the damaged one replaced rather than the whole roofs tiles. It probably would have been a better idea to have the both things done together the loft and roof fixed at same time would have been easier fo the roofers to do it that way or if ur planning on doing thay yourself when they have taken off the roof throw out all the rubbish like the fibreglass and insulation. As it will most probably be old wet and not as efficient and effective as new insulation. it will probably be better to use the insulation sheets instead of the rolls anyway as u want maximum space in loft aswell.

I would let the roofers take a look and see what they think don't think them small upright s are doing very much

Them supports need replacing easy job to do get something like 6x6 or 5x5 notch out one end so the purling can be wedged/seated into it. As for the insulation wear a good mask,goggles,gloves & bag it up. It's a really dirty job but well worth doing :)

Roofer been in touch about the pictures , he said someone must have put those supports in at some time as they are not original and people sometimes put them on for extra support.

I don't get this though as if they weren't there what would be taking the load. I understand the beam runs right through mine and my neighbours house but it just ends in the corner and other wise wouldnt have support at the end . I guess this is normal then ??

the old ones look quite bad now and are moss covered. unsure of the style but i am replacing with terracotta double romans. i was given the option of replacing the ones that get damaged during the work but the difference in price to get new ones on wasnt a great deal as i was already forking out for scaffolding anyway and skip etc anyway so just thought i would get it all done at once and hopefully never worry about the roof again.

the roofer reckons they have been added by someone over the years and arnt essential but add extra support. i just dont understand what else there would be for support if they werent there. there would be nothing from the brick wall separating our houses in the loft to the end of my house to support them.

Yes if that's the case it's probably a better as most older roofs had clay tiles and urs prbably doesnt if its so damaged .they are better than concrete so people usally get advised to just replace the broken ones but if it's more than likely over 40 percent need replacing then it's cheaper to just use all new ones instead. ask the roofers to remove the stuff out of the inside if they wldjbr charge u too much or do it urself when the roofs off will be easier know with the scaffolding on than taking it out through the house and ruining everything I the process aswell.

They might have been put in to correct a roof sag; as above, the roofers should sort it all out and they will be in trouble if the new roof collapses.

I had my house re-roofed last year - made a huge difference; it cost me a fortune though, as the old tiles were asbestos.

You may find they dont do the best clear up afterwards though, my loft was left with bit of new tile off-cuts and copper pins.

I think your roofer is correct. I had my 1930's semi reroofed about 5 years ago and my roof looked almost identical to yours but it didn't have those supports, so I think they've been added later. They don't look to be nailed in so they may well just fall out once the roof is stripped and relieved of the weight of the tiles and roofers start clambering around and hammering. As to whether they're necessary, your roofer is the best one to advise on that - he'll have seen many roofs and will know how the design of yours compares to others.
Regarding that old insulation, yes get rid of it - if you think its dirty now you wait 'till they've finished, everything will be covered in a layer of dust, dirt, dead insects and nails, and Gentle Giant is right, they don't usually do a clean-up.
Regarding new insulation, will the converted loft become part of your house, a living area that you use all the time and want to be comfortable? If so then you want the insulation up above you in the new ceiling, not under your feet, otherwise its going to be cold up there.

The mould on the timbers is from high humidity levels. Probably blocked air ventilation caused by deep insulation or if you have a water tank in the roof space ill fitting or non-existent cover.
