House Guttering Repair

[carlyai]

I have some cracked joins in my metal house gutters.

What is the better way to repair these faulty gutter joins, either buy a big lump of copper soldering iron and solder, or buy a small propane gas torch and solder?

 

Which ever way is recommended, do you know if the solder and product are available on Lazada?

Depending how bad the cracks are, you can use this silver gutter tape:-

 

If the cracks are bigger or on a structural part try Flashing tape. It's a strong sticky tape that will hold your gutters together.

 

Something like this:- https://www.lazada.co.th/products/20-3-sealtex-flashing-tape-i287430529-s469350762.html?spm=a2o4m.searchlist.list.1.4b45142aAXDVVx&search=1

I have used this and it works great. your local home repair store might have it also.

A big iron would be best but that will be pretty had to find. Using a torch in conjunction with a piece of copper bar-stock works pretty well if the gutter is galvanized.

 

Is the gutter galvanized? Painted? Stainless?

The gutter is galvanised. I was a bit busy with other things when they put up the gutters and didn't see how they joined them. I was thunking soldered. I was up looking again last week and a few if the joins are leaking, or the soldered joint has failed. 

I could use tape or that black sealer, but not sure it would last.

Another method - sealant and pop rivets.

 

 

Old joint repair...

 

 

 

New to old joint with slightly different profile on the new section...

 

 

 

Cheap 90 degree drill attachment used to drill rear rivet holes from inside gutter...

The aluminium backed bitumen sealer tape is a permanent sealer as long as you don’t have a joint that moves. 
 

FWIW I’ve also used it to help reduce noise and heat inside the cabin of our pickup, it’s been there a few years now and seems to help.

This tape has been up for about 4 years and still does the job.

 

Any movement in the guttering and a new bit of tape will solve the problem.

If they're galvanized solder is the way to go, assuming you know how to solder.

 

If all I had was a torch, heating from the outside and soldering inside is how would do it. Do not overheat!

 

If you can find tinning fluid it will help...
