Box gutters are usually strong enough and wide enough that you can actually walk inside them. Box gutters are often on only one side of the roof, this is particularly common with flat metal roofing.
BOXED GUTTERS
All joints, stop ends and drainage points in the gutter are hot air fusion welded with PVC membrane straps or prefabricated accessories creating a permanent and homogeneous waterproofed system with a life expectancy in excess of 30 years.
Good Flow Rate: Box gutters are capable of managing significant amounts of water, making them perfect for commercial applications or areas prone to heavy rain. Versatile design: Suitable for both commercial and residential properties, offering flexibility in design and application.
The purpose of a box gutter is to collect rainwater runoff from the roof and direct it to downspouts, drains, or other drainage systems. Box gutters are often made of metal, such as galvanised steel, aluminium, or copper, although they can also be constructed from other materials like PVC or wood.
Installing box gutters can be necessary if you live in an area with more rainfall. They are effective at collecting rainwater and safely directing it away from the vulnerable parts of the house, like the roof and walls.
As noted, it is far more expensive to install box gutters due to the cost of the wood and the labor that goes into crafting and installing them.
Plumbing Regulations clearly state that box gutters must: Be straight.
The slope of the box gutter needs to be in the range of 1:40 to 1:200. Minimum 'freeboard' (extra height in the valley gutter to minimise the chance of overflow) of 30mm.
Slope should be from 1:40 to 1:200, however the calculator will give the depth of gutter required (if for some inexplicable reason) the gutter is laid without any slope. By the way, it is not a good idea to design a box gutter to be flat, as this allows ponding and rusting.
Unlike traditional gutters, which are attached to the edge of a roof, box gutters are installed in a recessed channel or 'box' that runs along the roof's internal perimeter. The box gutter is then connected to downpipes, which allow the water to be directed away from the building.
To prevent box gutters from overflowing, consider installing gutter guards or gutter mesh covering to keep leaves and other debris out and allow water to flow freely.

Rust-Oleum Combicolor Metal Paint is a superb metal paint that offers the various specific needs that exterior metal paint requires, such as anti-rust properties and the ability to apply the paint over previously rusted metal.
In most cases, it is more economical to repair your existing box gutters than to replace them. However, if the framing on your box gutters has suffered damage, this is a good time to decide whether to rebuild new box gutters in a similar style, or replace them with something more modern.

So what's the difference between box gutters and concealed gutters? Nothing. Box gutters are sometimes called concealed gutters because they're fitted discreetly beneath your home's fascia boards, giving your roofline a sleek, modern look; they are simply two different names for the exact same type of guttering.
The complexity of box gutter installation requires the expertise of professional contractors, as improper installation can lead to major issues, such as water damage, structural problems, and expensive repairs down the line. Also Read: 5 Modern Gutter Styles in 2024 That'll Leave You Speechless!
Box gutters are renowned for their durability and longevity. Although the exact lifespan depends on materials used and maintenance performed, on average, well-maintained box gutters can last anywhere from 20 to 50 years.
Sumps and overflow provisions
Box gutter sumps must incorporate either a side duct/channel overflow, or a high-capacity overflow device.
Box gutters, also known as trough gutters, are concealed within the roof structure. They are typically made from metal and are designed to blend seamlessly with the roofline.
Plumbing Regulations clearly state that box gutters must: be straight (without change in direction) discharge at the downstream end without change in direction (ie not to the side) and have a minimum depth of 75mm at the high end.
Cost: $160 - $230 per linear foot
Re-lining involves replacing the metal in your box gutters, restoring them to their original condition. The cost is higher than coating your box gutters, but it is the preferred method of repair if your box gutters are solid.
Changing box gutter direction has been a problem for centuries. Dam Buster now has the easy solutions! Dam Buster direction change devices use the power of gravity to easily and safely change the direction of water flow in box gutters, then take it to the point of discharge fitted with a Dam Buster rainhead.
A sump is a critical part of a box gutter installation as it allows excess water (particularly in heavy downpours) to be quickly removed from the guttering and prevent it backflowing under the roof sheets.
Sloped Yards - Homes built on slopes or with properly graded yards can naturally direct water away from the foundation, making gutters less critical. Drainage Systems - Incorporating drainage systems like French drains can efficiently manage water without the need for traditional gutters.
