flat roof

Hello I know I have a couple of flat roofs that are leaking as there are a couple of brown patches appear not long after we moved in once the rain started. They will be repaired soon. However on further inspection elsewhere near the two roofs there are what appears to be other brown spots...

We have a cold flat roof with a 1970s-style suspended office ceiling made of a metal grid frame and mineral fibre ceiling tiles. the ceiling has rock wool insualtion above it and still in good condition, with the original plastic vapour control layer and the roof has roof vents all around the...

I’m after some advice please. I’ve seen a Reddit user with my exact query, but they don’t look like they ever got a response. Basically I’m having some building work done but have been left confused by the join between the warm and cold roof. I have borrowed a sketch of what the situation...

How far should I go up with my ply? Should I strip more tiles either side for my ply to run down? Also would you put fittings strips at the end of my existing rafters.. Cheers

Hi, Is there a way for the return wall fascia boards to run level at the top and hide the fall/pitch of roof on flat roof extension? It’s a warm roof, finished in GRP and I have soffits extending on 3 sides with furrings giving a fall to the front in to a box gutter. I’ve seen a few different...

Hi, I had an asbestos garage roof which was professionally and safely removed, then subsequently had a new roof fitted. 6 x 2s, OSB, PIR, EPDM. All that is fine and roof is sound. However, as you can see there is a gap at the front of the garage where the old gutters and drain are. Can someone...

Hi all, We are doing a 6m deep rear extension and could really do with your thoughts _/\_ Our adjacent (party wall) neighbour currently has a 3m extension with pitched roof. We are looking to match the neighbours pitched roof (with pitched internal ceiling below) and then transition to flat...

Hi all, I’ve written up a detailed tender package for replacing a multi-part EPDM/rubber flat roof on a residential block that I live in after doing informal inspections with roofing contractors. There are issues with pooling, structural degradation, and signs of condensation damage due to poor...

Hi, Hoping I can get some advice from any roofers/anyone experienced in GRP fibreglass flat roofs. Thank you! We had a leak on our flat roof and agreed with what appeared to be a reputable roofer (couldn't find a local recommendation so had to go with online reviews...) that the existing GRP...

Hi I had a GRP roof done last week and the builder put the topcoat in the evening and the day before we had rain so I think the laminate/resin was wet on the roof (when he applied topcoat). Today I checked the roof and the topcoat is wet, some area with ridge and coming off when I touch it. When...

Hello I’m after some advice, I keep getting a leak in certain weather conditions, usually when there’s a wind. I would imagine the wind blows rain into a gap I’ve found in my roof felt. It’s definitely big enough for water to be getting in (see pictures). The gap is in a corner of the roof where...

Hi all. Looking to buy a semi detached bungalow. We know this one is a real fixer upper but am concerned by the major damp build-up in the corners of the flat roof extension. It looks like the flat roof will have to be replaced but as we are going to move forward on a full loft conversion...

My partner and I are mid self building a relatively large garden room and the roof (8m~ x 5m~) is causing some stress. I'm hoping someone can advise on how to proceed from where we're at. We had the EPDM laid over the warm roof for nearly a month before we had anything resembling good weather...

Hi all, I'm building a single skin brick garage. The garage is 6.1m long and 3.1m wide. I need some advice on getting the roof started. I'm planning to put the joists accross the shorter span and have the fall going towards the back of the garage. I will be using 47mm x 175mm C24 timber for...

We have a flat roof on our ground floor which acts as a large bay area to our living and kitchen area. It's approximately 5 meters by 2.5 meters. We have an issue in that the builder (who has since done a runner but that's another story) mis measured our steel and had to fit new steels after...

Hi I have an old flat roof which is failing. The roofers have stripped the felt and replaced some of the OSB. Underneath there's a (to my mind, not well constructed - e.g. gaps in insulation/no foil taping) cold roof, using PIR (I'd guess 75 or 100mm). The roofers have put on a VCL and PIR...

Hi Folks, I've got what is essentially a shed attached to the side of my semi, it's got a decaying flat felt (part torch on, part patched) roof and it needs replacing, but I'm also planning on making better use of the space so want to give it some insulation. The building is 2.3 meters high...

Hello, I am currently having a rear extension built and have had a warm flat roof installed. It is only now however that I have realised the wall insulation is supposed to carry on up to meet the base of the warm flat roof!! What would be the best way to insulate this gap before plasterboard...

I am after some help if possible on the below situation. I have a 1950s semi detached house and I am looking to convert the garage into livable space. It’s currently got an asbestos roof which I’ll have removed and disposed of. I need best advice as how to have the new warm roof. It’s 6 meters...

Hi Everyone, First time posting here, so sorry if I'm not doing something right. I bought an old (1919) house in June last year and have started some renovations in the meantime (new bathroom and new insulation), which are almost done. But after removing the roof fascia of the flat roof from the...
