Definitions

  • the present invention relates to roof flashing and in particular to a method and apparatus for flashing rooves around vent pipes and the like, to form a weather seal where such pipes pass through a roof.
  • a problem with the aforementioned conventional method is that they are relatively expensive both in materials and labour.
  • the lead sheet needs to be 14.66 kg/m 2 lead in order to provide enough material for dressing and is therefore relatively expensive to purchase. Furthermore, it is time consuming to perform the dressing operation and a special tool is required.
  • the invention therefore provides apparatus for flashing rooves around vent pipes or the like wherein a relatively thin sheet of material is adapted to surround said vent pipe or the like and form part of the roof, said sheet being provided, in use, with a hole through which said pipe passes, characterized in that, said apparatus includes an inner sleeve member adapted to fit over said pipe and pass through said hole and having an annular flange for engaging the underside of said sheet, an outer sleeve member of similar shape to said inner sleeve member and adapted to fit over said inner sleeve member, said outer sleeve member having an annular flange for engaging the upper side of said sheet, and a locking cap adapted for attachment to an upper end of said inner sleeve member in a manner applying a force on an upper end of said outer sleeve so as to force said respective flanges towards each other in a manner clamping said sheet therebetween.
  • Fig.. is a sectional side elevation of an apparatus for flashing rooves around vent pipes.
  • the apparatus for flashing the roof includes a thin aluminium sheet 11 which is used to replace a concrete or ceramic roof tile in the same manner as a lead sheet used in the past.
  • the aluminium sheet is provided with a hole already cut therethrough although in an alternative the hole is cut on site. The purpose of the hole is to facilitate passage of the vent pipe 10.
  • the aluminium sheet 11 is then placed in position and an annular rubber washer 15 is placed over the inner sleeve member 12 and slid downwardly to rest on the top of the aluminium sheet 11.
  • an outer sleeve member 16 is slid downwardly over the inner sleeve member 12 such that a flange 17 thereon bears against the rubber washer 15.
  • a locking cap 18 When both sleeve members 12 and 16 are in position a locking cap 18 is slid downwardly over the vent pipe 10 and is threadably engaged with the upper end of the inner sleeve member 12.
  • the locking cap 18 has a downwardly depending annular groove around the outer perimeter thereof for engaging the upper end of the outer sleeve member 16.
  • the flanges 13 and 17 are inclined with respect to the longitudinal axis of the respective sleeve members.
  • the angle of inclination is about 25° as this is considered a good compromise for enabling the apparatus to be used on most rooves.
  • the angle of inclination of a roof is somewhere between about 17° and about 35° and an angle of 25 0 inclination of the flanges enables the apparatus to be used in such a range of rooves because the aluminium sheet 10 is able to flex sufficiently to account for any variation in angle of inclination between the flanges and the actual roof.
  • the locking cap 18 Whilst the locking cap 18 may be a closefit over the vent pipe 10, it is necessary to provide a weather seal to prevent any water which runs down the vent pipe 10 from entering the underside of the roof.
  • a neoprene weather apron 19 is provided for this purpose.
  • the weather apron 19 resiliently engages the outer surface of the vent pipe 10 and is slid downwardly thereover to a position where a downwardly depending skirt 20 of the apron 19 is over the locking cap 18 and thus protects the upper ends of the sleeve members 12 and 16 from the ingress of water.
  • the weather apron 19 may be provided without a hole to accommodate the vent pipe 10 and such a hole may be cut on site by the user. This enables a common apron 19 to be used for a range of pipe sizes within certain limitations.
  • the apparatus of the above described embodiment is formed essentially from PVC.
  • both the inner and outer sleeve members 12 and the locking cap 18 are of PVC whilst the other components are formed from the materials previously indicated.
  • vent pipes are of varying sizes it is necessary to provide different kits of apparatus to take into account the wide variation in vent pipe sizes.
  • the aluminium sheet 11 may be provided with a hole therethrough which accounts for various sizes of vent pipes provided the variation is not too great.
  • the hole may be cut on site as with the weather apron 19 in which case one particular kit can be used for various pipe sizes at least within the range of variation which occurs between galvanized iron PVC and copper pipes of the same nominal diameter.
  • the rubber washer 15 may be provided in a size which is suitable for various sizes of vent pipe 10.
  • the neoprene weather apron 19 may be a more conventional PVC weather apron as has been used in the past although such is only suitable for PVC vent pipes and must be the exact size for the pipe.
  • the locking cap 18 may be attached to the inner sleeve member 12 by means other than a screw attachment such as for example a clip-on attachment although at the present time a screw attachment is preferred.
  • the present invention has considerable advantages over the existing apparatus for flashing rooves. Whilst a number of components are involved, the overall cost of materials is considerably less than the cost of a lead sheet as previously used. Furthermore, since installation of the apparatus is much quicker and easier than with the prior apparatus due to the fact that it is not necessary to use a special tool to dress the lead sheet the time involved in installation is far less. Thus, the savings in material and labour create a considerable saving in the overall cost of flashing a roof around a vent pipe or the like.
  • the apparatus will be sold in kit form it is conceivable that only the inner and outer sleeves 12 and 16 and the locking cap 18 will be provided along with perhaps the rubber washer 15.
  • the remainder of the apparatus that is, the sheet of material 11 and the wheather apron 19 is apparatus which is generally used by plumbers for other purposes and is readily on hand.
  • the sheet 11 would probably be omitted from the kit although in some instances the weather apron 19 may be included.
  • a second rubber washer similar to the washer 15 may be provided for insertion on the underside of the sheet 11 between the sheet and the flange 13 of the inner sleeve 12 although in most cases the need for this further washer is felt to be unjustifiable.
