BOX GUTTERS

Sydney Roof Construction is highly experienced in box gutter installation, repair, replacement and maintenance, having provided these services to countless warehouses and factories in Sydney.

Commercial box gutters must be at least 300mm wide and should be supported to allow for foot traffic during roof services or maintenance.

Box gutters are typically placed between parallel surfaces, as in a valley between parallel roofs or where a roof and a parapet wall meet.

Box gutters should include sumps to aid water flow and prevent water pooling as well as overflow outlets to prevent water from entering a building during extreme rain.

Sydney Roof Construction provide’s custom made box gutters using Bluescope steel’s Zincalume and Colorbond range.

 

Most factories have box gutters and many houses with edge parapet walls have some type of box gutter that either needs repair of replacement.

When box gutters leak, there are two ways that you will experience the result:

  • A deluge of water inside the property during a heavy rain or…
  • Slight dampness progressing to constant drips over a length of time.

Box gutter repairs for that deluge leak.

If you get flooded inside the property during a heavy downpour – then you have a blockage somewhere along your box gutter.

Box gutters in factories usually have sumps to collect the water and force it down the downpipe.

If the box gutter and sumps are not maintained regularly, you will get this….

This will cause a flood of water inside the property

There are design standards for sizing of box gutters and downpipes. But these designs assume no blockage. It does not matter how large the box gutter is – it will overflow if the downpipe outlet is blocked.

You don’t have trees?

Well, we once found a box gutter sump blocked by the combination of a sweets wrapper and a old coke can. It does not take much to cause a blockage…

The coke can has been there for a while…. the hole doesn’t help

At least these box gutter repair situations above can easily be fixed by a bit of clean up work.

What about overflow insurance?

You may want to sleep better during those stormy nights (after feeling a bit guilty about forgetting to clean your box gutter). If you have overflows in your box gutter, you can go back to sleep.

If you don’t – then you will need to seriously consider this option. An overflow is the most effective box gutter repair method to counter the sudden deluge leak.

A new overflow is the best box gutter repair option

Box gutter repair for those slow leaks

The slow box gutter leak has two culprits.

  • Leaking joint
  • Rusty box gutter

Very often, sealants break at the joints or pop rivets break off. Water will weep constantly during any intensity rain.

The repair is quite simple.  Clean the box gutter joint and re-seal.

The rusty box gutter has a temporary solution. A quick patch of the rusted areas will keep water out for a short while  – and allow for preparations for a proper job. Which is…

The main thing with box gutters that show premature rust is to find out why.

If there is ponding water – then the new replacement box gutter should not copy this error.

Proper falls to the outlets will increase the life of the replacement box gutter.

 

Box gutter repairs – the way forward

Putting overflows into box gutters or designing box gutters with a full with discharge through the parapet wall into  rainwater head is the best ‘bank for bucks’ – if you have a overflow problem.

If the box gutter is locally rusty and need replacement, then it pays to find out why it has rusted prematurely and have these factors eliminated with the new box gutter.
