• Tile roof - the measurement from the outside edge of the gutter to the base of the second tile
• Metal roof - the measurement from the outside edge of the gutter to the first row of fixing screws*

2. Measure the LENGTH (m) of the gutter to be covered
3. Choose the COLOUR

*On metal roofs, Blue Mountain Mesh™ is usually secured to the roof sheets about 20mm beyond the first line of roof fixing screws. This ensures a wide, downward sloping section of mesh that helps ensure leaves and debris are blown off the roof by wind or washed off by rainfall. It also prevents leaves getting stuck on roof fixing screws.

Measuring the WIDTH

Tile Roofs
Lay a flat ruler on top and across the first tile (the one that fits into the gutter) and slide the ruler up against the face of the second tile. By looking at the lowest section of the second tile assess that if water and leaves were flowing down the tile would they flow on top of the ruler. If so, order standard clips. If it looks like the leaves and debris would flow under the ruler order ‘Z’ (zed) clips. Standard clips are easier to fit than ‘Z’ clips.
Bullnose Verandahs
Measure from the outside edge of gutter to the “up flute” (closest point) of the roof sheet, then measure from the outside edge of the gutter to the first row of fixings on the roof sheets and the length of gutter to be covered.
All Types of Valleys
Measure the length of the valley and the width of the gap between the tiles or roof sheets.
