ᐅ Roof Tile Slope

Hello,

for the planned dormer windows, the roof pitch is 12°. The carpenter says that roof tiles with special roofing felt should not cause any problems regarding moisture and dampness. The roofer, however, tends to prefer a metal roof and advises against roof tiles.

Now, I am not sure which is the better choice. On one hand, I would favor the metal roof since it is probably the least problematic option. The somewhat higher cost compared to a tiled roof would not be an issue for the budget.

The only drawback to the metal roof I can think of is noise from rain. However, I am not sure how to assess that. Hearing rain or wind in an attic apartment doesn’t bother me; in fact, I find it quite pleasant. But if the rain noise becomes so loud that you cannot hear your own voice, that would be annoying.

I doubt it would be that loud, though. The roof insulation meets current standards.

Do you have any information for me? Personal experiences would be best.

Well, I don’t have much direct experience with this.

Only a partial metal roof – a holiday farm in the Allgäu region, which we used to own. Even on that old building, it wasn’t very noisy. That roof was built in 1974 and still exists today; I checked last spring.

I would also choose the metal roof. When done with the right materials and properly installed, it’s truly durable and reliable. Back then in Oberstaufen, winter lasted from November until Easter, with real snow and ice and the corresponding loads on the roof. That roof worked brilliantly—stable and practical.

I assume you have insulation under the roof. In that case, noise is rather negligible.

When heavy rainstorms hit here in Velbert during storms, I can hear the water running from the roof into the gutters and the pattering on the double casement windows. It doesn’t bother me at all—I actually find it quite cozy.

And we have a 38-degree roof pitch with tiles and plenty of insulation.

Best regards,
Thorsten

Bricks still work well at 10°C (50°F). We have experience with this on our shed roof. (see also the thread by Manusch).
