I am getting a single story, fibro stud wall extension built. It has no eaves, because of setback requirements from a sewer main. The roof has a relatively low pitch (5 degrees), and is corrugated zincalume.
I have heard that , in a big downpour, the gutter can overflow back into the ceiling.
Does anyone know if this is true, and how to avoid it.
Currently, the roofing iron is on, and the guttering is ready to install.
Thanks

Arent you supposed to put the gutter on first, then the tin? :?
Thats how its done on site..
the project homes being built these days dont have eaves (i presume to keep costs down?!) i havent heard of any consistent leaking problems with this set up...
how big is the area of your roof feeding this gutter?
my suggestion is ensure the gutters are installed with atleast the min fall needed and keep them clean!
Gutters arent installed with fall these days. :pQuote:

Pay a lot of attention to flashings and weathersealing of all doors, windows, etc on walls without eave overhang as they are much more exposed to storm conditions than they would be with 500-600mm of eave protection.
It's about 4.5 metres of tin feeding the gutter. Thanks for the adviceQuote:

I just realised that, because of the design of the roof, the gutter drops about 150mm over 12 m, so that should help run-off. I guess it could put pressure on the low end of the gutter though. I mean if it back flows to house, that would be the spot.
Thanks again,

you may like to consider putting in a leaf eater or similar exit on the gutter
this will make the gutter stay emptier as there is no restiction on the water exiting

In Port Hedland, and I guess many other places;
most houses have No Gutters.

It is either DRY,
or
DELUGE,
and ANY Gutter would just overflow.
This issue has been in the press a bit recently. this might be of interest.

Doesn't matter how much fall you have if the water can't get away.
My gutters often overflow to the front in a heavy downpour, even with the regulation number and position of downpipes. In extreme cases, they also overflow to the back despite the overflow perfs in the front, but it just runs down the fascia and to the ground because I have eaves.
next your going to tell me bricks arent layed to a string line these daysQuote:

It's not enough of a problem for us to worry about, but yes that would probably help.
