  "abstract": "The present invention 10 discloses an elastomeric skylight membrane molded as a single piece comprising a planar element 18 for sealably engaging roof sheathing 26 and a centrally positioned collar element 20 for sealably engaging the rough opening framing members 34. The skylight collar membrane 20 is inserted over the framed rough opening for a skylight 16 having the elastomeric collar element tightly engaging the framing members 34 and of substantially the same height as the rough opening frame members. The planar element 18 engages the roof sheathing 26 and is fixedly attached thereto by any means well known within the art. Positioned across the up slope side 36 of the collar 20 is an angularly protruding edge 32 for preventing water from wicking between the skylight frame 34 and the skylight membrane 10. To prevent lateral flow from the up slope edge 36 of the skylight 16 there are two spaced apart ridges 22 transversely positioned to the turnback collar sides extending above and below the horizontal edge 30 of the up slope side 36. The diverter ridges 22 spaced away form the turnback side 32 obstruct lateral water flow returning it to a downhill flow. The planar element 18 further has a bead 38 on three sides near its periphery that will redirect any water that has accumulated between the skylight membrane and shingles to a downward flow.",
  "claims": [
    "1. In an apparatus for a seal around an object passing through a pitched roof having shingles thereon, the roof thereby having an up slope side with respect to the object, the seal forming a flashing between the object and the roof, the object having a frame member which frame member passes through the roof, the improvement comprising: a) a planar member having a centrally disposed aperture therein for receiving the object, said planar member having a top side and a bottom side; b) a collar member disposed circumferentially about said aperture said collar member being in communication with the frame member, said collar member having its base disposed at its juncture with said planar member; c) a plurality of water diverter members disposed on said top side of said planar member, said diverter members disposed lateral to said up slope side of said collar member whereby water is prevented from travelling tangentially to said up slope side of said collar member; and, d) a turnback disposed at said base of said collar member.",
    "2. The apparatus of claim 1, said water diverter members being elongated with their longitudinal axis being disposed perpendicular to the longitudinal axis of said up slope side of said collar member.",
    "3. The apparatus of claim 2, wherein said water diverter members extend partially above and partially below said up slope side of said collar member.",
    "4. The apparatus of claim 1, wherein said planar member is elastomeric.",
    "5. The apparatus of claim 1, wherein said planar member is generally rectangular shaped.",
    "6. The apparatus of claim 1, wherein said collar member is elevated above said planar member.",
    "7. The apparatus of claim 1, wherein said collar member extends about six inches above said planar member.",
    "8. A. The apparatus of claim 1, wherein said turnback projects angularly from said base so as to prevent water from travelling up said collar member.",
    "9. The apparatus of claim 8, wherein said turnback is about ½ the length of said collar member.",
    "10. The apparatus of claim 9, wherein said turnback is disposed at angle of about 45 degrees with said collar member.",
    "11. The apparatus of claim 1, further comprising a bead extending circumferentially about three sides of said planar member so that water is diverted around said bead.",
    "12. The apparatus of claim 11, wherein said bead is disposed on said up slope side and said pair of lateral sides of said planar member.",
    "13. The apparatus of claim 12, wherein said bead forms a seal between said planar member and the roof shingles.",
    "14. The apparatus of claim 13, wherein said bead is about as high as the thickness of said planar member."
