ᐅ Costs of Flat Roof vs. Pitched Roof—Detailed Information Needed

Here, I am quoting a question of mine from another thread that may have been somewhat overlooked:

What costs more – a pitched roof with a traditional roof frame (not a truss roof) and tiles, or a flat roof that is also developed into a terrace?

I don’t need a detailed breakdown right now (which wouldn’t be possible without basic information) – I’m interested in a general trend to consider for future planning.

Thank you for your answers.

Definitely a flat roof. The cost is mainly for the waterproofing.

Definitely the flat roof option. This is mainly due to the more complex waterproofing required and also the fact that the roof is intended to be walkable. In my opinion, the latter only makes economic sense if it’s a two-family house and the second occupant or tenant does not have access to a garden.

In a typical single-family home, experience shows that a terrace on the first floor is rarely or never used because there is usually sufficient terrace and garden space at ground level. It’s similar to having a party room in the basement. That space might be used once or twice, then the homeowner usually encourages guests to move out to the terrace.

I know of other cellar rooms like that. You go in when it’s light outside and come out when it’s light again. So it really depends on the owner You don’t leave a nice counter just for a terrace

There are always exceptions to the rule

Thank you all for the feedback.

This rules out a flat roof option.
It might have been possible that removing the roof frame and tiles could have compensated for the cost of waterproofing or even resulted in some savings.

Well, I’m not a fan of flat roofs anyway, so this gives me another reason to avoid them.

Apart from the cost, what I like better about the flat roof option is that on the first floor there are no spatial limitations caused by sloping ceilings. Fully usable rooms, better furniture placement options... I find a full second story much more comfortable.
