We’re often called in after someone makes decisions without expert advice. These are the most common — and costly — mistakes we see:
Buying a rangehood without checking roof clearance or structure
You legally need at least 1200mm between the barbecue grill and the underside of your rangehood. This often places the hood much higher than expected — sometimes in direct conflict with beams, rafters or ceiling features.
Choosing the wrong motor configuration
You can choose from on-board, in-line, and off-board motors — each with unique noise levels, airflow efficiency, and installation requirements. Some structures are simply incompatible with certain types and brands of rangehoods — due to beams, roof pitch, or limited ducting access. Getting it wrong can mean starting over. Let us help you get it right from the start.
Incompatibility of Roof Type
Roof type is one of the most overlooked challenges in alfresco rangehood installation. Roof pitch, materials, internal beam structures, and the distance of other roof-mounted systems — like solar panels or air conditioners — can all affect installation. Some roof types severely limit ducting options or rule out specific motor placements. Our team knows exactly what to assess and how to make it work.
Assuming all alfresco kitchens are the same
They’re not. Roofing height, wall materials, power supply, ducting pathways, and cabinetry all vary — and impact which alfresco rangehood can be installed safely and legally.
Overlooking ducting complications
Ducting for outdoor BBQ rangehoods is difficult to plan without experience. Beams, supports, or tight roof cavities can restrict airflow and cause performance issues.
Installing appliances not rated for outdoor use
Alfresco kitchens face moisture, heat, and weather exposure. Without outdoor-rated appliances, your alfresco setup will deteriorate quickly.
