Description
FIELD OF INVENTION
[0001] The field of the invention is temporary roofing covers for
residential structures.
PRIOR ART
[0002] Sloped residential roofing is commonplace in all climates.
Such roofing is fully exposed to all manner of inclement and
damaging conditions, including weather conditions which rapidly and
radically alter the utility and lifespan of the roofing material
itself. This can be particularly adverse when the owner is not
present for long periods of time and the building is left to the
elements un-managed and unheated or only minimally heated. An
example, is the typical cottage or camp which may lie unoccupied
for much of the year and, particularly for long periods of
inclement winter weather where snow, ice and rain tend to
accumulate and may build up upon collections of debris in or on
eaves or in gutters and trip further debris in the process.
[0003] It is known among some cottagers to actually cover roofing
systems for the winter with tarpaulin sheets. These are thrown over
all or part of the roof and are held down by gravity with the
assistance of ropes and weights, most often by weights off the roof
edge. In most instances these tarpaulins are subject to such
weather abuse, and particularly high winds, UV and driving
precipitation that they are unlikely to remain in use for more than
1 season, often less. Often their presence in a damaged condition
adds to the deterioration of the building itself, its roof and
associated gutters, trim etc. Adding and improving the quality of
the tarpaulins used might seem to have benefit but the extra cost
and sheer mass involved have been found to be prohibitive.
[0004] Some of these matters are discussed in PCT patent
application PCT/AR/2009/000685 published on Dec. 10, 2009 and also
published as Canadian application 2,726,321 (herein CA'321), now
abandoned. CA'321 seeks to present a solution to the problem of
adhering adjoining strips from a working position while on the roof
and working with heavy rolls by forming a conjoined sheet of strips
cut to fit using the ground as the work surface, dragging this
sheet over the entire roof and then heat shrinking the result to
achieve a secure engagement between the complete structure and the
sheet.
[0005] And again in US Published Pending Patent Application
2005/0217202 published Oct. 6, 2005 on the application of Crook
(herein USPPA'202). USPPA'202 discussed a roof cover or protection
system directed at high wind situations. As far as understood Crook
asserts the use of heat shrinkable material to envelop the entire
roof in strips which are heat shrunk in to their cover
configuration. The individual strips may be taped down to the
roofing material. As can be seen USPPA'202 does not have specific
provision for rain, snow and ice. It discusses a one-time solution
which is directed at ease of installation of large and heavy rolls
of protective material. A solution to a gabled roof is to wrap the
entire roof with a strip in a spiral configuration and then shrink
it in to shape. This is not known to provide a useful and reusable
result.
[0006] Another complete coverage discussion is found in U.S. Pat.
No. 6,425,201 to Lachapelle issued Jul. 30, 2002. In this the
protective layer is provided in strips which are sticky and
stretchable. On the roof the strips are up and over and are then
sealably attached to the wall layers.
OBJECTS OF THE INVENTION
[0007] Objects of the invention include provision of a temporary
and reusable roofing cover:
[0008] which may be installed, removed and re-installed with a
minimum of skilled labour or a home owner in a safe and secure
manner, and,
[0009] is adapted to resist water, snow and ice and particularly
built up snow and ice, ice dams and resultant water intrusion into
the building, and,
[0010] which may be easily and inexpensively fabricated on site
without complex fabrication steps on the roof itself, and,
[0011] which may be installed with a minimum of manipulation of
large rolls of material on the roof itself.
STATEMENT OF INVENTION
[0012] The invention provides a temporary roofing cover for
residential buildings with sloped roofs having 2 or more roof decks
with a plurality of overlapping highly elongated body strips of
waterproof material, each adapted to extend horizontally across a
single roof deck, a highly elongated ridge cap strip adapted to
extend between an adjacent pair of roof decks along their ridge
joint and overlap one of said body strips on each roof deck, and
fastening means along at least each elongated edge of each of said
strips adapted to secure each edge to an adjacent strip in said
overlapping relationship along said elongated edge and a method of
fabrication and installation at a remote work site.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0029] In FIG. 1 is shown a partial cross-section of a typical roof
structure 1 during winter conditions with a snow load 7 and an ice
dam build up 9. Typically roof structure 1 includes a plurality of
roof plates or surfaces with deck supports or trusses 2 and roof
decks 3 which may be plywood sheathing. Further typically, the roof
deck 3 is covered by rows of individual shingles 4 installed in
overlapping position, upper layers over the lower layers, from the
lowermost edge 3a at gutter 8 upwards along direction 16 to ridge
line 1a.
[0030] In typical winter conditions a snow and ice load 7 may build
up significantly. In some climes this can amount to an extra roof
loading of tons. During periods of freeze and thaw or with freezing
rain the roof gutter structure 8 is not capable of handling run off
and an ice dam 9 may form along the roof edge above and including
gutter 8 further adding to the roof loading. Further run off then
backs up into a pool 10 of melt water and mixed ice crystals which
accumulates on the roof 1.
[0031] Pooled water 10 does not drain away and starts to penetrate,
as at 11, the roof shingles 4 and the deck 3 to accumulate further
as water or water and ice 12 in attic space 5. Pooled water 12 then
drains from attic space 5 into the ceiling joints 6 and interior
drywall 13 to cause water damage to the drywall as at 14.
[0032] As shown in FIG. 2, a preferred roofing structure includes a
permanently installed ice and water shield 15 along the lower edge
3a of the roof sheathing 3 adjacent gutter 8 and lowermost shingle
4a. Most typically this ice shield 15 is a single continuous strip
in the order of 30 inches in width and prevents water entry as at
11 in FIG. 1.
[0033] As further shown in FIG. 2, snow load 7 can build up to such
an extent that ice dam 9 can extend up the roof deck 3 a
considerable distance as at 9a, effectively dividing the snow load
into an upper portion 7a and lower portion 7b which may be
incorporated into the ice dam 9. This is particularly so in
locations where the subject building is not fully occupied or
heated during the winter months. In these cases the actual load 7
may be significantly increased from that of FIG. 1 and provide for
pooling 10 higher up the roof deck 3 along direction 16.
[0034] In FIG. 3 is shown a perspective view of a simple
residential building with a square profile and end gables 17a and
17b respectively. The roof structure 1 In FIG. 3 includes an
adjacent pair of roof decks 3a and 3b covered by lateral rows of
individual shingles. The exposed shingles are not shown for ease of
illustration.
[0035] In accordance with the preferred embodiment of the temporary
roofing cover of the invention a highly elongated protective strip
of waterproof material, the ridge cap 18, is first applied along
and parallel to the ridge line 1a with equal depending portions 18e
and 18f, on the front and back side respectively, extending down
roof 1 in direction 16 to line 21a and from gable 17a to gable 17b.
Strip 18 may be imprinted with a shingle pattern on its uppermost
surface as shown at 18a.
[0036] Ridge cap 18 is installed to roof 1 overlapping ridge line
1a in direction 21 along line 21a in FIG. 4. The underside of cap
18, referred to as 18b in FIG. 4, includes a full width zipper-type
fastener 18c, and, preferably, a full width hook and loop fastener
18d, referred to as a velcro-type fastener, along each of its lower
edges 18g and 18h respectively. Further preferably, zipper
fasteners 18c are immediately adjacent each of lower edges 18g and
18h respectively and hook and loop fasteners 18d are adjacent and
just inside the zipper fasteners.
[0037] A plurality of protective main highly elongated body strips
19 are installed to roof 1 downwardly from ridge line 1a along
direction 16 and from gable 17a to gable 17b in direction 22. Main
body strips 19 form parallel lines 22a across the roof 1.
[0038] As shown in FIG. 5 each of main body strips 19 include a
preferably continuous hook and loop fastener 19b along its upper
edge and a preferably continuous zipper fastener 19a immediately
adjacent the hook and loop fastener. The upper face of strip 19 may
be printed with a shingle pattern 19c.
[0039] Similarly, a lower protective strip 20 is installed to roof
1 adjacent the gutter 8 along line 23.
[0040] As shown in FIG. 6 the lower strip 20 includes a preferably
continuous hook and loop fastener 20b along its upper edge and a
preferably continuous zipper fastener 20a immediately adjacent the
hook and loop fastener. The lower edge of strip 20 is fitted with a
series of snap fasteners 20d extending from its lower surface. The
upper face of strip 19 may be printed with a shingle pattern
20c.
[0041] FIG. 7, in parts 7a through 7e, depicts the preferred
embodiment as fully installed to roof 1 in corresponding plan
views.
[0042] FIG. 7a shows the back side of the ridge cap 18 with its
fold line 18i which corresponds to the roof ridge line 1a upon
installation. Pairs of zipper fasteners 18c are adjacent the lower
edges 18e and 18f and corresponding pairs of velcro-type fasteners
18d adjacent each of the zipper fasteners 18c.
[0043] Upon installation, the ridge cap 18 is rotated about its
long axis 18i so that zipper fasteners 18c and velcro-type
fasteners 18d correspond with mating zipper fasteners 19a and
velcro-type fasteners 19b, respectively, on the first middle strip
installed.
[0044] FIG. 7b shows the top side of the first middle strip 19
which is installed to the roof 1 immediately adjacent ridge cap 18.
With installation the mating velcro-type fasteners 18d and 19b are
joined along their respective lengths to hold strips 18 and 19
together in place while zipper fasteners 18c and 19a are joined for
complete closure of the uppermost joint.
[0045] FIG. 7d shows the underside 29 of the middle strip 18 with
its zipper fastener 29a and its corresponding velcro-type strip
29b.
[0046] FIG. 7c shows the top side of the 2.sup.nd middle strip 24
which is joined to the first middle strip 19 along its entire
length by sliding under middle strip 19 from position 27 to
position 28 in direction 26, upwards along the roof 1. Mating
velcro-type fasteners 24b and 29b are joined along their respective
lengths to hold strips 19 and 24 together in place while zipper
fasteners 24a and 29a are joined for complete closure of the second
and subsequent middle joints.
[0047] FIG. 7e shows the top side of the last and lowermost highly
elongated strip 40 in plan view. From the top strip 40 is
preferably the same as main body strips 19 and 24 shown in FIGS. 7b
and 7c respectively. The underside of strip 40 is preferably clear
of velcro-type and zipper fasteners as are shown in FIG. 7d in
favour of a series of snap connectors 43a aligned with gutter
8.
[0048] FIG. 8 shows an expanded perspective view of the gutter 8 of
the preferred embodiment including a series of snap connectors 43b
which correspond to connectors 43a on lowermost strip 40 so as to
receive and secure strip 40 firmly to roof 1 upon completion of
installation. Additional snaps 44 may preferably be secured to the
distal ends of the roof structure 1 to secure distal ends of the
body strips 18, 19, 24 and 29.
[0049] In FIG. 9 a hip roof embodiment of the invention is shown
adapted to a hip roof with main roof plates 45 and 46 which include
the roof structure 1 shown in FIG. 1 and the corresponding main
ridge line 1a. Roof structure 1 also includes hip ends or plates 47
and 48 which are separated from main roof plates 45 and 46 by hip
ridges 49 and 50, and by 51 and 52 respectively. In this embodiment
the ridge cap 18 is extended at both ends 31 and 32 by hip
extensions 33, 34, 35 and 36 permanently affixed to ridge cap 18,
each corresponding to an individual hip ridge 51, 52, 49 and 50
respectively.
[0050] Each of hip extensions includes a fold line 33i, 34i, 35i
and 36i, respectively, along its central longitudinal axis which
corresponds directly to and overlies hip ridges 51, 52, 49 and 50,
respectively, upon installation to hip roof 45. As with ridge cap
18 each of the hip extensions, as with extension 33, includes an
outermost zipper-type fastener, as at 33c, on the underside
adjacent each outer edge and an inner velcro-type fastener, as at
33d, inboard of each outer zipper both along the full length of the
