Abstract

For sealing the ridge cover of a pitched roof there is used a sealing strip (10) comprising a center strip (11) with an air-permeable, water-repellent and drifting snow-tight non-woven material (12) including side strips (20, 30) contiguous therewith, at least the outer longitudinal edges of said side strips being adaptable to the top surfaces of roofing tiles (2'). Each side strip comprises soft, extensible polyisobutylene sheet strips having an expanded metal embedded therein which exhibits a longitudinal extensibility of 50 to 150% and a transverse extensibility of >20% and a recovery of >5%.
