Roof terrace/deck above standing seam metal roof - modern techniques?

[cheetah1]

So should one make wedges of type NTR-A for it to rest on regardless?

Yes, I think so anyway, with some form of rubber sheet/setup between the sheet metal and the timber. Preferably made of EPDM rubber, which retains its softness even when it's cold.

I guess that Resitrix or stainless steel roofing is applied over a subroof of raw boards?

How do you handle the vapor barrier in such a construction?

And what is the slope of the roof, one centimeter per meter?

Wondering

(I have just recently learned the difference between balcony, patio, terrace, and veranda).

Not many people know this, you see the words being used pretty much interchangeably daily.

But a small addition: Terrace rests on some form of solid base, not only on a roof, it can also be directly on the ground.

The roof is built like a regular roof, air gap, raw boards, felt, and then reistrix or sheet metal.
The plastic is on the inside of the construction if that's what you mean.
With resitrix, no slope is needed, but about 1cm/m so that the water drains off controlled is good. For double-lock seam sheet metal, I don't know, but would guess the same.

Nope. Double folding leaks if water remains standing over the ridge. At least a 4° slope I've heard many times and adopted myself.

Hi
Found this old thread and read that "Double-folded leaks if water stands over the ridge". In what situations can so much water become standing?
Is it snow you're thinking of then?

 

[Johan Gunverth]

Type. If meltwater remains inside snowbanks, it can create a water level above the highest level of the rebate ("ryggen").

Hi. Found this old thread that touches on exactly what I'm pondering. Has anyone done this and would like to show a picture? I'm mostly thinking about how it looks from the side since the roof underneath is sloping.
