What is claimed is: 1. A roofing system for use on a base surface of a roof comprising: at least one roof panel, located above the base surface, having at least one longitudinally extending projection that extends to a bottom edge of the roof, a gap is defined by within the at least one longitudinally extending projection and located between the base surface and an interior surface of the projection facing the base surface, and a venting material located within the gap at the bottom edge of the roof that both vents the gap and prevents ingress of moisture into the gap, the venting material comprising a venting closure strip located between the roof panel and the base surface, the venting closure strip comprising at least one rib that conforms to a shape of the gap and at least two valleys of lower cross-sectional profile than the rib, one on either side of the rib. 2. A roofing system for use on a base surface of a roof comprising: at least one roof panel, located above the base surface, having at least one longitudinally extending projection that extends to a bottom edge of the roof, a gap is defined by within the at least one longitudinally extending projection and located between the base surface and an interior surface of the projection facing the base surface, and a venting material located within the gap at the bottom edge of the roof that both vents the gap and prevents ingress of moisture into the gap, the venting material comprising a venting closure strip located between the roof panel and the base surface, the venting closure strip comprising at least one rib that shaped to fit within the gap and at least two valleys of lower cross-sectional profile than the rib, one on either side of the rib. 3. The roofing system of claim 2, wherein the rib expands within the gap. 4. The roofing system of claim 2, wherein the rib fits within the gap in an interference fit. 5. The roofing system of claim 2, wherein the rib is larger in shape than the gap. 6. A method for venting an area between a roof panel and a base surface of a sloped roof, the method comprising inserting a venting material between an interior surface of longitudinally extending projection on the roof panel and the base surface of the roof at a gap; wherein the gap is defined by within the longitudinally extending projection, wherein the venting material is an air permeable plug or a venting closure strip comprising at least one rib that shaped to fit within the gap and at least two valleys of lower cross-sectional profile than the rib, one on either side of the rib.
