roof

Hello everyone, I have just started a new job in the commercial and industrial roofing sector, as a trainee estimator, are there any commercial/industrial roofers on here that would mind answering a few questions of mine please?

This is a section of my flat roof extension. The top rafters simply support a suspended ceiling below the original ceiling. The bottom ones are only approx. 500mm short and are placed inside the RSJ that supports the building and connected to the frame that supports the roof light, I cannot...

Our Victorian property has a flat roof side extension for the kitchen. The kitchen ceiling is in part under the original property and in part under the flat roof. A long RSJ props up the original wall of the house. We are going to fit a ceiling extractor above a new kitchen island. The...

Any views on this mechanism of insulating conservatory roof? Have been looking at replacement roof but perhaps this may be more economical? What are the disadvantages? https://www.insul-8.co.uk/

Hi there, I had my roof done last year and chimney flashing replaced on both sides - the house is a terraced and our neighbours had theirs done at the same time. We have leaks coming in from the corners of the room (it’s an attic bedroom) also - there’s an unused fireplace with a lot of grit...

Hi there - help really appreciated! Around 5-6 years ago our roof started leaking. We were advised it was the valley that was leaking and paid for it to be sealed (I'm not sure with what). This week it the same leak has started again. We have had 3 roofers out who have all advised...

Hi everyone, just looking for a bit of independent advice until I get a professional in to take a look. We moved into a 20 year old house about 2 years ago, house had been empty for a few months and there had obviously been some escape of water/roof leak at some point and the plasterboard...

Hi Folks, I as ever need a little guidance to enclosing the exterior steps to my basement. There was a rickety roof with fencing panels for the sides, the roof has rotted and in a race I pulled it all down before it fell down, well it could have been a dead heat. I do not know where to start and...

Hi, This is a small flat roof that joins to the house and main pitched roof. Some background info: It has never had any insulation between rafters and doesn't have insulation on top. Timber roof joists/rafters with timber furring. Then plywood and then torch on felt. We discovered the...

Hi - this is my first post here and I was hoping someone could advise. I have recently moved into a 3 bed semi detached dating from the 1930's, the house is slated in good quality Welsh slates but had no 'breathable' membrane. We have just had the slates removed, a membrane fitted...

Hi all, I have recently bought a house (1920s/30s) and want to insulate my loft. Currently there is about 100mm of fiberglass between the joists and floored with chipboard. I really need the loft for storage so rather than add extra glass wool I want to use multifoil under the rafters - it looks...

We have been living in our house 16 odd years and of late have noticed that we have small walls in the loft that hold up wooden beams that act as some sort of roof support. I think they're called purlins from reading online. Our house is semi detached and there is a single purlin on the left...

Got a quote for my roof to be refelted with breathable felt, new battens and the original slates reattached with recon slates where needed. Needed as no ventilation to the roof space and numerous slates have slipped. My slates are a completly different size to the neighbours and the tie in is...

Hi. Please be patient with me as this is my first big build! I'm an Engineer by trade though so reasonably confident once I understand the basics. I'm planning a large garden workshop and would like to flat roof it with Classicbond EPDM. The actual structure will be 6x4m in Thermalite blocks...

Hi All, I'm planning a single storey rear extension on my 1930s terraced house - 4.5m deep, full width of the house - 6m. The house is on naturally sloping land, higher at the front. At the back of the house, there is a 0.7m drop to the patio and then a 0.4m drop to the original ground level...

Hi guys, Would anyone be able to suggest the best way to frame this flat roof (cold roof because of height restrictions)? Will be using C24 9” x 3" and all the internal walls are solid block load bearing. I was thinking about creating a 2 way fall to each side with firring strips. OSB and then...
