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...

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 all, I moved into a property a while back and it's got a kind of lean to building attached to the side. It's essentially a custom sized insulated (poorly) shed. I've had a ton of issues with the roof felt leaking at one end and despite some rather rushed patching I'm not overly confident in...

Hi All I am looking at using epdm on the roof of my summerhouse (18mm osb) should i put any sort of barrier between the osb and epdm? (to me it seems obvious to just glue it to the board) roughly how much adhesive would I need for 18m2? for this size roof would 1.14mm be ok? I have been looking...

Hi All. I am looking for some advice. I need to fix some cladding up the wall and wrap it over the roof parapet. I really need to secure the cladding to the parapet and it’ll need an air gap that is continuous with the wall. The parapet is marine ply with EPDM and is at an angle of about 30...

Hi. We have had a flat roof kitchen extension built, with EPDM and two skylights. The company that built it pulled out of the project neat completion, it was really weird and I don't know why they didn't finish it but I get the feeling that they misquoted and were just cutting their losses at...

Hello, We have mould appearing on the internal plywood of our garage roof in the past few weeks during the colder/wetter weather. I wondered if anyone could give an insight into why this might be happening? The mould appears between every joist front to back, mainly appearing from the edges but...

I am putting a new flat roof on a brick built garage, stage 1 is to get the roof watertight and stage 2 next year is to make it into a green roof, probably sedum. The garage is approx 5.25m x 3m with joists to run across the width (3m) I have been looking at some of the weight considerations...

Hi Guys, new to the forum and DIY in general. Note, I have no DIY experience at all, except for assembling home furniture. I had a garden building built in 2018, and now the flat felt roof has already failed and caused a massive leak inside the building. Large puddles form on the roof, and...

First of all thanks everyone for helping with my self build, so much appreciated. Next stage complete the parapet wall design,roof timbers on for warm roof.My plan is to complete the top of the parapet wall either side,them fix the roof down. Need to keep the parapet wall to minimum height...

Hey there, I'm after some advice on replacing the roof on our block-built double garage. The existing roof appears to be constructed of Tin Corrugated sheets, which have well and truly had their time, with lots of holes all over the place. The roof is approx 4.8m at the widest point x 6m...

I'm reroofing a porch roof, approx 3 square metres. Planning on 18mm ply (joists are sound) with EPDM on top. Is it worth spending time and money getting firestone rubbercover, or would something generic like 1.1mm EPDM with adhesive from rubber4roofs be as good?

Hi. A few years ago, my parents paid a considerable amount of money to have their flat, cold, felted extesion roof into a warm, EPDM roof. It was OK at first, but a leak formed and started to drip onto the internal windowsill. Not only that, but there was water pooling in places, directly below...

Hi, Can anyone show me an image of how the framing of the fascia and soffit should meet the pitched roof. I've been told by neighbour builder that the fascia and soffit should go all the way into the roof and then lead all over that. Fact is there is an internal gable wall stopping that and it...

Been looking for weeks but cannot find any specific details on this; I'll try to explain but apologies if I waffle. I'm building a garden studio, timber frame, without overhang. The top of the cold roof has 25mm air gap above celotex insulation then osb roof, then will be epdm. The walls have...

About to wrap my timber framed garden office with the breathable membrane and battens but am unsure how the edge detail is finished with an EPDM roof. The cold roof rafters end flush with the stud wall rather than any overhang. If I go by the limited diagrams seen so far (see attached), then...

Hi there. I've had some very helpful advice from this forum recently, but need some more if possible. Just wanted to confirm the insulation specs. The plan is currently; Floor 75mm PIR insulation laid directly on concrete with glued battens spanning front to back as a fix for scaffold...

Hi, I need some advice if possible on the best type of membrane for a timber framed structure for a garden office. I was going to have the stud wall, membrane, battens, then ply cladding sealed with Osmo oil. Parts of the cladding might be open joint cladding with vertical battens, but am...
