There are many reasons for people to get re-guttering work done, but by far the most common one is rust, soon as that stuff appears you have problems and that tells me you don’t have good water flow towards your down-pipes and your gutter is holding water. The slope or angle has to meet QLD standards as we have high rainfall here in Brisbane at times.
Now in Queensland with any new build there are new rules to how the gutter is installed. The new QBCC Guidelines say we now have to put spacers in-between the metal or timber fascia and gutter of 3-5mm to allow for the 1 in 100 super storm of water volume
This is to keep the gutter off the fascia so that if the drains block up and the gutter overflows it can go over the back between the fascia but not over it into the ceiling space or the gutter eves. this is all calculated by length of roof sheets, roof area, number of down Pipes, size of down pipes, size of gutter, size of the overflow slots on the front, also type of gutter etc.
So after the fascia is up completely I stick on a few spring clips (about 4m apart) then roughly click the gutter on to the fascia
From there I place in the gutter the spacers (at equal distance apart) no more than 900mm apart. I then proceed to clip the spacers over the back of the gutter
Then put the rest of the spring clips over the top of the spacers and adjust to get the correct fall (1mm fall over 500mm of length) now I take off the first spring clips and slide in the spacers and re clip on the clips
I place the over straps in the gutter at the same place as the spacers and put them on
Cut the downpipe holes in, silicone it all up then move on to another section
there are a lot of types due to different brands which all have different patterns, styles, etc. but at least they all use Colourbond colours which gives you a choice of over 25 different shades
