ᐅ Are roof windows really not feasible with a roof pitch of about 12°?

Hello,

we have a single-pitched roof (with a weatherproof underlayment) with a slope of about 12° (a bit more). We would like to install a roof window in the stairwell area; however, our architect tells us this is not possible due to the slope (only from 15° upwards). Raising the gable to adjust the slope is not an option for building code reasons, as we would then exceed the maximum allowed height.

I did some research and so far only found windows from Vitral that are suitable for slopes between 0° and 30°, but the architect says these are only suitable for flat roofs, and so on.

Surely it must be possible to install a roof window on single-pitched roofs with a 12° slope — we can’t be the first in 2018, can we?

Any ideas?

Thanks.

This issue has now been resolved:
After Braas/Velux spoke again with the carpenter, a roof window will be installed using a tapered frame – it was a very difficult process.

If anyone encounters a similar problem, feel free to get in touch, and I can share the "component list."
