Nothing more unsatisfying than trying to dig a hole with "stuff" in the ground. It's either stones, tree roots or in some cases old building rubble that was dumped and covered over with fill.

The opposite can be true. Built a fence down at Whangamata. The place is basically all sand and digging post holes was like digging on the beach!

A guy who did our guttering (continuous steel) for me thought that Marley specify a slow fall so the gutters retain some water to provide a thermal buffer.

The continuous steel on our current place is ~6 years old. We are in a salt spray zone but also get reasonably high rainfall. The stainless (304) lamps outside are rusting the spouting is just fine. Early days of course but no signs of corrosion anywhere at all, not even at corners etc.

PVC downpipes (painted as per covenants) show signs of movement due to expansion and contraction.

You end up with mosquito larve in the summer though if the water is pooling, as well as sludge from leaves etc,, so not great for health.

kryptonjohn: We have 60 yo copper and it leaks. Can't see where from either.

These days I believe they just join them and fill gaps with silicon. So you should be able to easily fix them, guess it is called general maintenance.

As long as there's a fall and the clips are installed dead straight there should be no standing water. It might be slow but it should go (apart from a small amount that will soon evaporate.

Personally I like marley PVC

It looks nice and tidy if professionally installed.

Copper will rust and i have seen a few houses that have the concealed system leak into the attic if they arent cleaned properly.

Depends on the house, it suits some but not others. Not really that suitable for a really nice modern architectural design, unless you go for one of their coloured half round ones.

Copper should take many many years to corrode, as they use it for water pipes! Not unless there is something acidic causing it to prematurely corrode, or it is really poor quality or an alloy.

Easier said than done though, especially if they have to use joiners in long lengths. One downside with concealed brackets is cleaning the gutters out as it i smore fiddly, and I don't think the concealed type can be used in all wind conditions.

If only it were that easy.

There's water dripping from under one of the clips but I think it's running to there from somewhere else before dripping. As I said, I cannot see where the leak is. There's no visible hole. The spouting is very old. If it was new and smooth and shiny it might be easy to find the leak but it's old and green and rough.

It is probably near the end of it's life. Some building products these days only have to last a relatively short amount of time under the BC. Not sure what it is for gutters, but wouldn't be surprised if it was only 10-15 years due to easy ease of access.

Agreed - it doesn't look all that sound to me and is probably ancient. Currently doing a full exterior repaint so have some fixed scaffolding up. Might get someone to quote on replacing it. The cost of the spouting itself is not too bad for Raincloud PVC - about $10/m for white not sure about the colours. Plain rectangular 10m x 20m hipped roof so 60m required.

It should be fine for that and probably the cheapest option. I think I have got stormcloud on my current roof and it is a good 20 years old with a normal hipped roof. When branches fall off trees and break parts of it, it can be easily patched up too as it is a product they have been making for decades..as long as they don't change the sizes in the future.

You'll probably make a bit of money selling the copper, as it is a precious metal.

I missed the age and agree its likely to have moved a bit.

Laser levels are great tools. I first used one as labourer on a building site in the 1990s for concrete boxing. Made the job so easy. Lift till tone and fire! Just like Top Gun.

I was hoping to use one when I re-clad the our (1920s) house in 2004 but everything was still level flush and plumb. Mind you the soil there had so much river stone, that digging a strainer post-hole was a psychologically scarring ordeal.

Rather spookily this spam turned up in my mail box today. Coincidence or is banggood spying on me?

[edit]

I think a 360 degree laser would be more useful though.

That would be nasty. I regularly deal to our (plastic) drainage sumps in summer to keep the mossie larvae away.

Wouldn't have happened at my place near Blenheim though. Too dry/windy.

In my experience copper lasts a lifetime except for physical damage. If yours is 60 years old it will even be thicker than modern copper. I would suggest you try to keep it and repair the leaks. The leaks will not be from corrosion. My 2c

As long as you don't have acid rain copper should go green, then last for a very long time. Joints would be the most likely point for leak - either from fastenings or solder failing. Copper is very cathodic and most other metals in contact with it will act an an anode and corrode before the copper.

Modern copper spouting is done as continuous so there are only joins at the corners and ends (if any).

But the initial cost

I put the Marley Stratus coloured PVC on my house and have been pleased with it. I chose pvc because live near the coast and didn't want ot to rot out like the old steel guttering. I spent a little more on the coloured stuff as it looks far better than white pvc. Time will tell how it lasts but has a 15 year warranty. Its been up for 18 months.
