<p>TITLE: ROOF FLASHINGS FOR USE WITH SOLAR COLLECTOR A roof flashing structure for use in sealing the tubes and wires leading to and from a solar collector where said tube and wires pass through the roof has a generally flat plate with an upstanding housing integrally formed with the plate, both of a rigid material. The flat plate has an opening in it where the housing meets with the plate and the upper end of the housing has an opening wherein a resilient elastomeric sealing member is located. The elastomeric sealing member has an upper surface and a lower surface and includes a plurality of generally circular apertures extending upwardly from the lower surface. Formed with the upper surface over the top of each of the apertures as an upstanding boss which seals the apertures. Within the interior of each of the apertures are a plurality of sealing flanges locator one above the other along the length of the aperture between the lower surface and the sealed end. Each of the sealing flanges extends circularly around the aperture and projects radially toward the center of the aperture. The top portion of the bosses are capable of being severed by a sharp instrument unsealing the aperture. Each of the flanges within the apertures are capable of forming a seal with a tube or a wire passed through the unsealed aperture.</p> |
