Claim:
A venting band for pitched roofs, comprising: at least two side strips extending parallel to one another, and at least one venting channel extending parallel to the at least two side strips, wherein the at least one venting channel comprises a portion of the at least two side strips forming a pair of walls which contain first and second sets of through-holes respectively, wherein a labyrinth is formed in the at least one venting channel by either an offset disposition of the first and second sets of through-holes or by obstructions which are positioned behind said first and second sets of through-holes, the labyrinth thereby deflecting air entering one of said first and second sets of through-holes to follow a path defined by said labyrinth, said air not passing directly to the other set of said first and second set of through-holes, wherein the venting band can assume a first and second, wherein the first state is the compressed state, in which the at least one venting channel is compressed, whereby said first and second sets of through-holes are not opened, and wherein the second state is the uncompressed state, in which the at least one venting channel is not compressed and said first and second sets of through-holes are thereby opened, wherein between the at least two side strips is disposed a center strip, and wherein the at least one venting channel is provided between one of the at least two side strips and the center strip.
