The guttering profile you should use is dependent on building specifications, environmental conditions, and the type of project you undertake.
Deepflow (or deepstyle) guttering can carry up to twice the water volume than a standard half round system can. Therefore, deepstyle guttering is the right choice if you live in a place with regular heavy rainfall or if you have a large or steep roof.
