Thought I'd add this to the blog but would be very grateful for some advice. Some construction background: MBC timber frame, flat roof, pumped insulation in roof void. Make up of roof is Sarnafil (hot welded) laid on a felt base, on top of 22mm OSB roof (with a slope), on top of 22mm OSB roof deck (flat - slope provided by battens to create the fall), then 400mm pumped insulation between the roof joists, air tight membrane, battens, 12mm plasterboard and skim. Roof lights on the flat roof (including a lovely round one, subject of another blog post). Yesterday we had some drips coming through the finished ceiling, about 700mm from the edge of our circular rooflight. We cut away some plasterboard to see what is going on. Plasterboard soaking wet, batten soaking wet and looks like the insulation is soaking wet. There is some water damage closer to the rooflight too, visible in the photo, but we started our cut at the plasterboard edge which is where the water started seeping through - the low point I guess. Have contacted roofing supplier and rooflight supplier (both of whom fitted their product). What shall I do next? I can't help feeling that without detecting the source of the leak neither supplier is going to help us. Any thoughts? Cut away our ceiling until we find the edge of the problem? (as we get nearer to the rooflight bit of course we are 7m off the floor ☹️)

MBC are pretty much done now and it looks like my luck with the weather is about to run out as some rain is due next week. I want to get a load of polythene that i can chuck over the roofs and anchor down to try and keep the worst of the rain off it. Its mostly the garage roof I'm concerned about. Does anyone have any suggestions of what I should use?

Hi I am planning where the gutters and downspouts need to go .. ..i know the wife wants things to be as TIDY as possible at the front and back (The sides are invisible to us and anyone due to trees one side and a high fence at the other) I see how others have built SIMILAR Potton homes and where they put their downspouts ... Let me know if you think I have planned well please Also a) Do you think the downspouts either side of the Sunroom are necessary ....as there is a ceramic patio tiling going all around it and i think it might make it look messy ? b) also i was considering ...it might be daft ....but is it possible to FLIP a downspout around the corner ? basically to maintain the clean look of one side of the house ?

Having moaned about the lack of protection of my xtratherm during the house build, I now find that the garage build insulated with 100mm rockwool is randomly unprotected, protected with sacking, protected with DPC. So it has got wet in the recent horrible weather. Person A tells me it will dry out Person B tells me it never dries out Given this is an unheated garage of 70m2 I can't see how the insulation in the wall can dry out. Questions: Whats the normal accepted practice (and ideally what is best practice) for looking after the rockwool type insulation during a build? Will it really dry out? Thanks
