To select the correct mesh width for your Box Gutter installation, first measure from the top of the Box Gutter (parapet wall) down to your roof sheeting. Add a minimum of 150mm to this measurement to ensure that 100mm of the mesh covers the roof sheeting, and 50mm on the Box Gutter side.
Installing the mesh with a slight slope helps debris to move away from the gutter opening. If the Box Gutter is too wide for attachment at the top, secure the mesh to the side of the Box Gutter, aiming for at least a 45-degree slope to enhance effectiveness.
To ensure an accurate measurement of your gutters, it is essential to add a minimum of 250mm to each individual gutter length when calculating the total meterage required. This extra length accounts for necessary overlaps in the mesh required during installation and provides leeway for any adjustments needed when cutting the mesh.
For safety and precision, we recommend measuring each gutter length from the ground. Should you need to measure from the roof, please exercise extreme caution.
Regarding valley measurements, measure from the roof capping down to the outside edge of your external standard guttering. When measuring the valleys, if possible, measure from a securely placed ladder. If roof access is necessary, ensure you take extreme caution and use appropriate safety precautions, such as a roof safety harness.
Please be advised that we will supply you with the exact amount of metres of mesh you order. We do not provide additional material beyond what is ordered. To accommodate any offcuts and overlaps, we suggest ordering a slightly larger quantity than your measurements indicate.
