Yeah. Thing is though if you go too much slope the house or shed looks wonky.

If the fall is towards the down pipe than the gutter shouldn't hold any water at all.

Really? I always thought water flowed up hill.

Seriously though I know the standard fall is for both cosmetic and practical reasons, ie. so the flow isnt too fast for the down pipe or so you dont need a down pipe at either end because of the length of the gutter, but now that I know what it is it just seems that it should be a bit more as things move over time and im guessing this is why they end up holding water, not because they were installed incorrectly.

I guess it also comes down to the guy doing the work and whether or not they skimp on the number and distance between the support brackets for the guttering.

The ideal spacing between gutter clips?
What do real roof plumbers think of the pre-made corners bunnings sell ?
External clips are easyier to clean the gutters.
Of all the roofs I've been on as an Air-conditioning bloke if the guttering pooling It'll be rusted out in 10 years.

If the fall is towards the down pipe than the gutter shouldn't hold any water at all.

That depends on a number of factors.

1. The roof area that is draining into each gutter,
2. The number and diameter of each downpipe,
3. The volume of rainfall at any particular time.

Modern gutters are slotted along their length to permit overflow when the drains are unable to cope with the volume of rain falling. Our house was built around 1920 for a guess, but sometime years ago, the gutters were replaced with box gutters, around 200 mm deep. The problem is, they didn't increase the number of downpipes (which would have been easy with old homes because they usually drain straight into the unkerbed street gutters), so in very heavy rain, those overflow slots are working overtime.

More like poor workmanship. LOL. Hands up anyone who's bathroom or laundry floor drain works properly.
