Different Gutter Sizes (various options)


There are several different shapes and sizes of guttering one can buy, choosing the correct product will depend on your needs:

Is your current set up unable to cope with heavy rain? Does your gutter overflow even though it’s not blocked? These are all signs of a low capacity gutter issue. Installing a larger gutter may help but there are other things to consider.

If you installed a larger, higher capacity guttering system, will it connect (join up) with any neighbouring gutters? Will it look out of place on your home?

Below are the Four Most Common Gutter Profiles

The Mini

This guttering is used exclusively on sheds and very small outbuildings, it is unique and probably won’t match up with any other known brand. It is designed to be as discreet as possible.

You can buy products like this from some DIY stores such as B&Q. It is unlikely that any trade outlets will keep this product in stock as demand for it is quite low.

Semi-Round Guttering

This is by far the most popular shape/size guttering within the United Kingdom. It can be seen on most domestic homes. It can be purchased from almost all DIY stores and most reputable trade outlets.

Most brands are compatible with each other, with only a few rare exceptions. This product doesn’t hold as much water as the Squareline products but does look more aesthetically pleasing. You can usually buy adaptors so this product will connect with the Squareline gutter.

This shape guttering is also available in cast iron.


This is the next step up in terms of size and water handling capacity. It typically holds 25% more water than the traditional semi-round gutter.

Not all Squareline guttering systems are compatible with each other, so if you are installing to a terraced or semi detached property, make sure you check the neighbouring gutter first.

This product is considered to be quite modern in appearance and is generally seen on newly built homes. White is the most popular colour but black, brown and grey can also be purchased.

Deepflow Guttering

This type of gutter is similar to the semi-round but is much deeper at around 95mm. Used primarily on domestic homes it can hold significantly more rainwater and most brands are compatible with each other, although it’s always best to check and confirm first.

This guttering can be used on refurbishment projects where the original gutter system is unable to cope with the levels of water discharging from the roof.

Always check that the gutter can connect with any neighbouring systems.

Ogee Gutters

Ogee gutters are unique to each other and most are not cross-compatible. They typically hold more water than the standard semi-round gutters and sometimes more than the deepflow.

This gutter has a very distinctive gutter profile and is usually installed to high-spec buildings.

Hidden in-line gutter support clips can be used, these will improve the appearance of the gutter quite dramatically.

Want to Keep Your Gutters Clear and Free of Blockages?

Gutter Hedgehog – This is a brush like product that is laid into the gutter, it is manufactured in 4 metre lengths and can removed and re-installed very easily.

Gutter Foam – This product doesn’t work as well as  I initially expected. Here is my experience of this product and why I will never use it again.

Gutter Grid – This is similar to the Gutter Mesh but is far more rigid, it won’t collapse into the gutter but does have large holes that catch pine needles.

Downpipe Filter – This filter only costs a few £s buy will prevent costly blockages in the underground pipework. Use with or without gutter guards.
