Your Allcoast Gutterguard installer will firstly ensure that all gutters and valleys are clear of leaves and debris. Most commonly an air blower is used to clean the gutters which removes both the bulky leaves and sticks and also any fine dirt and dust. It can be a messy process but clearing all debris is important.
Your chosen mesh product will be rolled out over the top of the guttering. The material is secured to the gutters outside edge by installing a Colorbond© flashing with class 4 self-drilling screws every 250mm. The mesh colour should be determined by the colour of the roof while the flashings and screws are colour matched with the guttering.
Now that one edge of the mesh is secured to the guttering, the other edge needs to be prepared for installation to the roof. Strategically positioned relief cuts are made in the guttermesh, coinciding with the contours of the roof. This fabricating process helps the mesh shape to the roof profile and ensures a professional finish.
On tiled roofs the product covers the first row of tiles and the second row of tiles are lifted slightly and the gutter mesh tucked underneath. The tiles are lifted individually, then carefully repositioned. On a metal roof, specifically designed clips are screwed onto the roof to hold the mesh down firmly against the corrugations. Both processes result in the mesh blending in with the roof and eliminating any access for leaves or pests.
Uniquely, our products are also effective on roof valleys. For tiled roofs the mesh is cut to suit each individual tile on both sides of the valley creating a saw tooth appearance. On metal roofs the product again extends from one side of the valley to the other and secured to the roof sheeting. Protecting the valley gutters is very important and often a source of internal flooding when left unprotected.
The final step in the installation process is securing the mesh at the hips and gables. For tile roofs high quality roof and gutter silicone is used to fasten the mesh to the ridge capping and any areas where the tiles can’t be lifted. For metal roofs silicone is not required as the mesh is fitted securely to the existing capping and flashings. Both methods ensure that all areas that leaves or pest can enter the guttering have been addressed and protected.
