INSTALLATION OF A STEEL BEAM
INSTALLATION OF THE TIMBER RAFTERS
CONSTRUCTION OF THE ROOFLIGHT
CONSTRUCTION OF THE WARM DECK ROOF
ROOF INSULATION INSTALLATION
COMPLETION OF THE ROOF STRUCTURE
WATERPROOFING OF THE ROOF
TORCH ON FELT APPLICATION
COMPLETION OF THE UPSTANDS FOR THE ROOFLIGHT

You really should have insulated the upstand because there was no reason not to. Now you have a warm area meeting a cold so you’re bound to have constant condensation during winter
informative vid . the vapor movement will find it's way through the untaped gaps and rot the ply though surely
No vapour barrier between deck and insulation ?
exactly what I thought... that will come back to haunt them (the home owner)
looks like you forgot to install a vapour control layer under the insulation on top of timber deck.... failed LABC regs. likely roof will decay
I was wondering about that
Not just me that noticed that then.....
Vapour control layer can be added inside, taped and sealed under joists.
It looks like you haven’t tapped the joints on the insulation panels!
lots and lots of mistakes and essential points left out in this build. I wouldn't be surprised if the ply moulds after 2 years.
Can the steel beams be replaced with timber for a single three bed room?
Someone's gonna break an ankle, what fucking mess.
Make a video that has the flat roof built from scratch
The installation of the felt is totally wrong. You never cross bond layers, a venting partial bond layer should have been used as a base layer, the joints in the deck need to be taped, and the deck should have been primed.
I will be doing something similar except my bram will have headplate attached and i will be having a 150mm insulation warm roof . Anyone reading this would it be a good i dea to have upright metal posts or lay the beam onto existing wall , thanks in advance .
Underlay had not been laid to the fall of the roof ?
Thanks for information
Could you show how it looks after it rains? I just had my flat roof redone and there are a bunch of pools of water and it looks like possibly air pockets....not sure. It's making me nervous.
Hey did you get problem sorted? I need to get my flat roof done and had 8 people around and getting nervous I may choose wrong person
Hello, thanks for the knowledge shared....Are these roofing systems applicable in tropical countries?....dont see such here yet interested
Quite a few things wrong with this roof.
Genuine questions: why is the upstand for the roof light not insulated ?
Because the owners wife always takes a shit against it .
What’s the slope drop per inch on each foot? I would like to do something similar. Nice vid. Thank you!
What would be the max. span (wall to wall) for a 2 by 12 soft wood ceiling joists (12 being vertical), that would not bend under snow or it's own weight? i'm looking for a direct approximate answer, i just don't get the online tables ?
Where's the vapour barrier ?
What size ibeam you can use on a 10m x 18mm flat roof residental garage?
Good job though.
Hi can you tell me please what thickness of plywood you use First if you tell me that I appreciate thank you
18MM
You guys rock!! Fantastic work!!
not the best noggins 9.14
What size is that steel?
Didn't see any pad stones
Would you mind telling me what size steal beam have you used ?
looked like a 200
How thick is your plywood here?
18mm
This is not a warm roof.
Why? Looks to be done correctly?!
The decking should be under the insulation and the felt should be on top of the insulation.@@TheNorthernmunky
Wouldn’t both ways work well? Having the ply under the insulation may also cause cold bridging from the edge of the ply in to the void?! We usually put ply under and over and we insulate all the perimeter joists
@@TheNorthernmunky I would think the felt should cover the edge of the ply. Where is the void?
@@TheNorthernmunky correct 👍
