The invention relates to a ventilation strip (10; 110) for ventilating the eaves, a ridge or an edge of a roof, with at least one section (12; 114, 116) extendable along the ventilation strip (10; 110) which can be fitted to the shape of contoured roofing panels, and a section (14; 112) which is substantially rigid along the ventilation strip (10; 110) and parallel to the first section. The extendable section (12; 114, 116) has elongated holes and/or slots (30) in mutually staggered rows transversely to the ventilation strip (10; 110) and the elongated holes and/or slots (30) in one row are separated by at least one longitudinal web (34) running along the ventilation strip (10; 110). A ventilation strip (10) for the eaves may have apertures (20) for guttering brackets (70) and in a strip (110) for ridges or edges there may be an extendable section (114, 116) on either side of the rigid section (112). The extendable section (114, 116) may be folded in a zigzag with longitudinal fold lines (122, 124, 126, 128). There may ben an air-permeable and/or waterproof material covering (134) extendable longitudinally and transversally at least in the extendable section (12). |
