With all due respect, that is incorrect. Clay roof tiles can be installed on roof pitches between 12° and 22°. With this relatively low roof pitch, different measures need to be taken to secure the roofing materials (clips).
Based on my experience, the success rate is close to zero, unless there are additional exemptions from the regulations regarding roof styles in your building area; for your information, challenging the applicable development plan can take between 3 and 5 years with an uncertain outcome.
Are you sure you understood your architect correctly?
Kind regards

We now want to build a flat roof, or rather our architect ... He believes this should work since a 15° roof pitch is not really much and is therefore almost flat. At 15°, standard roof tiles can no longer be used on a gable roof (rather bitumen membranes or metal roofing).

How do you assess our chances of getting approval for a flat roof?

Hello,
Why doesn’t your architect check the zoning plan beforehand?
Poor to very poor. You can throw the plans in the bin.
Best regards

maestro678911 Aug 2011 13:04Hello everyone,
Thank you very much for your feedback.
With all due respect, I never said that clay roof tiles are completely impossible; with clips, it would certainly be possible. But even with clips, there can be issues with water penetration. Any reasonable structural engineer would recommend installing a waterproof membrane under the clay tiles at a 12° roof pitch.
Our architect did review the site development plan beforehand. In fact, we want to try together to convince the building authority that a flat roof makes sense for us. The final communication strategy hasn’t been fully developed yet. We also have plans from him with a pitched roof (15° slope), and even if the building authority doesn’t approve it, the house still looks good on the plans with a pitched roof. Priority number one, however, is the flat roof, as it would emphasize the Bauhaus character of the planned house. According to our architect, even when a site development plan is in place, there are sometimes opportunities to push through changes at the building authority.
The trash isn’t there yet! 😉
Best regards

You can even break a finger while picking your nose 😉
The roofing at 12° pitch is installed over battens and counter-battens to ensure sufficient ventilation. Then, a self-adhesive, vapor-permeable underlay membrane is applied. From experience, I know that sometimes structural engineers can contradict themselves; but it’s not that bad 😀
Kind regards
