I do love a roof terrace but given this photo got posted on Lemmy I suspect it may be overlooked by a very affordable Airbnb.
This gutter pipe leading half the rainwater from the roof to this deck is just asking for trouble… why not extend it just a bit?
EDIT: oh no it’s even worse, if you follow the roof further up where the wall is, there is another pipe from another roof section collecting water directing it to the deck, LOL.
To be fair, if you look further down the picture it comes straight out a scupper.
But yeah, there’s no real good reason all that extra water has to run across the porch floor when it could be piped across it instead.
Why does the top roof just dump the downspout onto the flat roof below it? I would think it would be better to just pipe the upper spout into another gutter/downspout and not give water the chance to pool on that roof/floor bit.
Frankly, it looks like both gutters are an aftermarket addition, which kinda makes sense for an old enough building. And if each individual unit is doing its own drainage work, the temptation to kludge it is real.
Pretty sure they have made a slight canal in the tiles, which leads the water straight to the next downspout.
Where an such homes be found?
Guessing not in America with the shitty zoning laws we have.
