Two Sided Guttering Kits 100mm - Extension

Guttering helps your building divert running water away from the walls and windows which means the cabin will stay drier, reducing the amount of treatments you may need to do. 65mm gutters are recommended for small garden buildings, whereas 100mm gutters are suitable for larger garden buildings. Our four sided guttering kits are designed for square roofs only.

Guttering Size Needed

The amount of guttering that you would need depends on the size of the cabin, but you will also need to include the roof overhangs. For example: if you have a 4x4m cabin with an apex roof, the 4m is not including the roof overhangs, meaning you would need the Complete Gutter Set - 400cm and the 200cm extension set to ensure you have enough guttering for the full length of the roof, If the roof then projects further than 5m you would also need the outlet extension set due to the increased area of water collection.
