Abstract ROOFING SYSTEMS A roofing system includes ducting members 3 secured to and saddling the rafters 1 at the eaves of the building, such members 3 including duct forming portion 16, either side of a central portion of inverted "U" cross-section, arranged to define air flow passages either side of the rafters 1 thereby to ensure adequate ventilation of the roof space which might otherwise be impaired by insulating materiel pushed into the eaves from inside the roof. The members 3 extend only partially between the rafters l, and are sufficiently self- supporting to maintain the duct forming portions substantially in the desired position thereof.
