ᐅ Splash guard for roof overhang?

Hello!

We are currently planning the splash protection, paths around the house, and the terrace. We have a roof overhang of about 80 cm (31.5 inches). Can I plan the splash protection on these sides to be less than 30 cm (12 inches)? Especially in the terrace area, I wonder if 15 cm (6 inches) would be enough with an 80 cm (31.5 inches) roof overhang. What do you think? Regards 😉

So you’re planning wall – splash guard – terrace? Actually, the terrace usually starts right at the wall. There is no separate splash guard, or rather, the terrace itself acts as the splash guard.

How high is the roof overhang above the ground? And what orientation is it – on the windward side (west), you’ll need more than on the east. What follows after the splash guard?

Hello!

The roof overhang will be 2.70m (8 ft 10 in) high and 80cm (31 inches) wide.
The terrace will not be level with the finished floor level. So, we are planning a step.
I am a bit unsure about this, as we had two different opinions on the matter.

In which cardinal directions would a splash guard make the most sense?

That doesn’t matter: the terrace replaces the splash guard. You just have to make sure that rainwater drains away properly there.
Do you have a bungalow with an 80cm (31.5 inches) roof overhang? Won't that make the interior too dark?
Back to the question: the weather-exposed sides should receive more attention.
Personally, for aesthetic reasons, I would want them all to be the same height.

*LOL* I’m familiar with prevailing wind directions, but a prevailing rain direction would be a new one for me 🙂

Well, in Germany, the weather-exposed side is usually the west side. More precipitation tends to reach under the eaves there than on the east side.

I think the original poster is confusing two concepts here: splash protection (which prevents soil from splashing onto the façade) and drainage strip (which keeps the base of the façade dry). A gravel strip around the house is an excellent solution for both purposes. A paved terrace also prevents dirt from splashing up, but proper drainage still needs to be ensured.
