ABSTRACT
A pipe support is used for supporting the pipe on a roof. The support is a
molded thermoplastic component with a pedestal in the form of a hollow, truncated
pyramid. A concave pipe saddle is formed in the top of the pedestal. An integral flashing
flange surrounds the pedestal, at its base, and projects outwardly from the base for
integration into the structure of a roof, either a sloping roof or a flat roof.

CLAIMS
1. A pipe support for supporting a pipe on a roof comprising a pedestal having
a base, a top side, a concave like saddle in the topside and a flashing flange around the
pedestal, projecting outwardly from the base.
2. A support according to Claim 1 wherein the pedestal and the flashing flange
are integral.
3. A support according to Claim 1 wherein the pedestal and flashing flange are
integrally formed from molded thermoplastic material.

5. A support according to any one of claims 1 through 4 wherein the pedestal
comprises a plurality of pipe saddles.

Description

The present invention relates to pipe supports and more particularly to
supports for supporting pipes on roofs.
The current practice in supporting a pipe on a roof is to use stacked lumber,
nailed together, or concrete blocks. The pipe is set onto the wood or concrete and is held
in place using a clamp. Pipes of the type in question may be, for example, those used for
the supply of natural gas.
Premanufactured supports are known for use with flat roofs, with these are
generally unsuitable for use with sloped, shingled roofs, where the support must be held in
place against slipping on the roof and where the support should not interfere with the
impervious properties of the roof. It is also desirable that the support is esthetically
acceptable.
Pipe supports according to the present invention are intended to mitigate one
or more of these problems.
According to the present invention there is provided a pipe support for
supporting a pipe on a roof comprising a pedestal having a base, a top side, a concave pipe
saddle in the top side and a flashing flange around the pedestal, projecting outwardly from
the base.
The flashing flange may be integrated into a shingle roof, with one side of
the flange under an adjacent shingle course above the support and the opposite side
overlapping the shingles below. The support flange may a1so be mopped into a tarred, flat
roof. The support is preferably an integral, hollow plastic molding, with the pedestal in
the forrn of a hollow, truncated pyramid.
In the accompanying drawings, which illustrate an exemplary embodiment
of the present invention:

Figure 1 is an isometric view of a pipe support according to the
present invention; and
Figure 2 is a longitudinal cross-section of the support of Pigure 1.
Referring to the accompanying drawings, there is illustrated a pipe support
10 molded integrally from a synthetic therrnoplastic material. The support includes a
pedestal 12 in the form of a hollow, truncated wramid. The pedestal has upwardlyconvergent end walls 14, upwardly convergent side walls 16 and a flat top wall 18.
Extending across the top wall, parallel to the end walls 14 is a saddle 20 in the form of a
semi-circular recess.
At the base of the pedestal 12 the support has a peripheral flashing 22. This
is a flat flange projecting outwardly from the base of the pedestal.
In use, the support is placed on a roof at a location where a pipe is to be
supported. On a sloping roof, the flashing 22 is inserted under the adjacent shingles on the
upper side, while the remainder of the flashing flange rests on the lower shingles. Thus,
the support is integ~ated into the shingled roof without interfering with the impervious
nature of the roof in any way. The support is aesthetically more pleasing than a stack of
lumber or concrete blocks.
On a flat roof, the support may be set on the flat roof during construction
and mopped in when the roof is tarred.
The support of the present invention provides a pipe support of e~cellent
stability that can easily be incorporated to any type of roof structure.
While one embodiment of the present invention has been described in the
foregoing, it is to be understood that other embodiments are possible within the scape of
the present invention. The dimensions of the support may be varied widely to

accommodate pipes of different sizes and different pipe heights above the roof. The
support may, where necessary, be provided with plural saddles in the top surface in order
to accommodate plural pipes. It is therefore to be understood that the invention is to be
considered limited solely by the scope of the appended claims.
