Roof flashing is an essential element of the roofing system and is required to create a water-proof seal on your roof. It is needed where you have the pipe extruding from the roof to expel the air from your rangehood. At Pacific Air, we bring to you efficient roof flashing solutions. Our collection includes steel roof flashing and tiled roof flashing that is adjustable for both 125mm and 150mm kits. The former is made of UV resistant EPDM rubber, while the latter is made from both EPDM rubber and aluminium sheeting.
These are included in the steel roof range hood kits and tiled roof range hood kits.
You will need to cut the hole larger in the EPDM rubber on the flashing to fit the galvanised pipe through. At Pacific Air, we recommend that you put the pipe under the flashing to work out how much to cut off. Always be conservative as it is easier to cut off. Cutting is easy with either standard scissors or shears. We recommend always use a sealant between the galvanised pipe and the flashing to ensure a water-tight seal.
When installing the flashing on a tiled roof, sometimes removing a tile completely is required. In other installations, cutting a tile is a more effective method. Some installers prefer to cut the aluminium part of the flashing to suit. Others prefer to fold or lay it out over the tiles. Always tuck it under the higher tile to ensure that rain does not flow under the flashing.
We encourage roof flashing to be installed by a professional such as a roof plumber - as it can be a complex task - and particularly difficult without having the correct tools. The main objective at the end of the day is to ensure a water-tight seal, so do use a hose after installation to check if any water has entered into the roof cavity.
