benediktr22 Dec 2019 18:35We are planning a new build with a low-pitched mono-pitch roof, with a slope between 7° and 10°. Now we are faced with the question of how it should be constructed and covered. The basic dimensions of the house are 10.99 x 10.865 meters (36.0 x 35.6 feet), and the roof is designed to slope upwards towards the north. The orientation is exactly 0° south. We plan to install a photovoltaic system and are now wondering how to design this roof in terms of thermal insulation, soundproofing, cost-effectiveness, and, of course, durability.
Option 1:
Reinforced concrete ceiling on the upper floor, insulation, and a framed roof structure with standing seam metal roofing
Option 2:
Same as Option 1, but with Braas 7° roof tiles
Option 3:
No reinforced concrete ceiling, but a truss construction; roof covering either metal or Braas 7° roof tiles
At the moment, I prefer Option 1 because it is executed as a cold roof and metal roofing is the better covering choice for the desired slope. I would like to hear your opinions and experiences regarding this.

Hello
Very nice, finally a shed roof again.
Under the reinforced concrete ceiling, the metal roof is surely not audible anymore. The standing seam metal roofing is watertight at this pitch, but not exactly cheap. However, if the roof is covered with photovoltaic panels, unfortunately, not much of the beautiful metal will remain visible. The insulation is almost independent from the roof structure anyway.
Why does the roof slope upward to the north? In my opinion, it looks much nicer if the roof slopes to the south, so the house can open up to the sun with large windows.

In my opinion, it would look much nicer if the roof sloped to the south, so the house opens up to the sun with large windows. However, for that to make sense, the ceiling would have to follow the roof pitch.

Metal roofing can be heard during precipitation. I wouldn’t recommend it.
I can’t say anything about the rest. It’s clear that it can be heard. A roof window is audible as well. Maybe someone here in the forum can share their experience. I think the ceiling with drywall and insulation will absorb some sound.

I see this longing here disappointed – the original poster doesn’t seem to want a recognizable shed roof but rather one that looks like a flat roof. If I wanted a flat roof, I would build one. Have you considered how much height difference a roof pitch of 7–10° makes over 11 m (36 feet)? If you have, you’d realize the desired roof clearly reflects the shape of a shed roof. How you want to define it is up to you.
If you have constructive input on the mentioned options or even want to suggest another alternative, that would certainly help not only me but all other readers as well.
