[0001] The present invention relates to a gutter-like flashing member for use between roof
penetrating structures installed in an inclined roof surface comprising a first sheet
portion adapted to engage a side surface of a bottom member of a first roof penetrating
building structure, and a second opposed sheet portion adapted to engage a side surface
of a top member of a second roof penetrating building structure arranged below the
first roof penetrating structure. The invention further relates to a roof structure
including such a gutter-like flashing member.
[0002] When a roof window or like roof penetrating structure is mounted in solitaire, the
joint between it and the roof structure is typically made water-proof by means of
a flashing assembly comprising upper and lower flashing members adapted to be mounted
in a horizontal position between the roof surface and the upper and lower frame portions
of the window, respectively, as well as first and second side flashing members adapted
to be mounted in sloping positions between the two side frame portions and the roofing.
The flashing members may be said to form a collar around the window, and to waterproof
the joint between this collar and the window the flashing assembly further comprises
cladding or cap members. When rain etc. hits the roof above the window, water drains
off from the roofing onto the upper flashing member, from there onto the side flashing
members, then onto the lower flashing member and finally back onto the roofing below
the window.
[0003] In some geographical areas roof windows are often mounted in the so-called "Encastrée"
manner where the window does not project as far above the plane of the roofing as
is normally the case. This type of mounting improves the insulation properties and
is thought to be more aesthetically pleasing, but it may entail problems with drainage,
particularly when two windows are to be mounted one above the other and a horizontal
gutter-like flashing member is used between them. The problem is particularly related
to cases, where the gutter is also used to drain off water condensing on the inside
of the second, lowermost window, as it must then be located below the level of the
inside of the window pane.
[0004] A possible solution to the problem might be to give the side flashing members used
with the second, lowermost window a smaller slope than the roof, thus making them
lie deeper in the roof at the top of the lowermost window where they contact the gutter
flashing member. Such a difference in slope between otherwise parallel parts of the
window and flashing may, however, has been seen to lead to lack of precision in mounting,
possibly caused by a deliberate misplacement in the attempt to make the flashing look
nice. Furthermore the overlap between the side flashing and cap members will vary
corresponding to the difference in slope, thereby becoming either to small or unnecessarily
large at one end.
[0005] Another solution is disclosed in the applicant's earlier patent application nr.
PCT/DK03/00748, where a section of the side flashing member located at the gutter in the mounted
state has a decreased slope and may be said to "lift" the water up to the normal level
of side flashing members. This solution, however, requires the use of specialised
side flashing members, which not only makes the flashing assembly relatively expensive,
but may also involve the risk of the leakages due to wrongful mounting.
[0006] XP055361384 discloses another gutter-like flashing member.
[0007] It is therefore the object of the present invention to provide for an alternative
and cheaper flashing assembly for use in Encastrée mounting of roof windows one above
the other.
[0008] This is achieved with a gutter-like flashing member according to claim 1, which comprises
a third sheet portion interconnecting the first and second sheet portions and constituting
a gutter bottom, said third sheet portion being substantially plane and arranged so
that the interior angle between the first and third sheet portions is smaller 90 degrees
and the interior angle between the second and third sheet portions is larger than
90 degrees, the first and second sheet portions being substantially parallel. This
effects an inclination of the bottom of the flashing member in relation to the pitch
angle of the roof, so that the part of the third sheet portion closest to the first,
uppermost roof penetrating structure comes to be located deeper in the roof than the
part closest to the second, lowermost roof penetrating structure. This means that
the flashing member effectively forms a pocket closest to the first, uppermost roof
penetrating structure, which is capable of receiving water drained off from there.
Once received, the water will run over the third sheet portion towards the second,
lowermost roof penetrating structure and thus effectively be lifted in relation the
plane of the roof. When eventually reaching the second roof penetrating structure
it will be forced to the side and thus run out onto side flashing members, which may
be of the traditional, substantially plane design. For this purpose the joint between
the second and third sheet portions is preferably substantially at level with these
side flashing members, but may also be located above them.
[0009] Seen from a drainage point of view, it will be optimal if the angles between the
sheet portions are adapted to the pitch of the roof in which the gutter-like flashing
member is to be used so that in the mounted state the third sheet portion will be
horizontal. For a roof with a pitch angle of 20 degrees this means that the interior
angle between the first and third sheet portions should be approximately 70 degrees
and the interior angle between the second and third sheet portions should be approximately
110 degrees.
[0010] The horizontal orientation of the third sheet portion, however, requires that the
exact pitch of the roof is known when picking the flashing assembly to be used and
a separate flashing member must be provided for every roof pitch angle. Alternatively,
the flashing member could be provided with means for adjusting the angle, but this
will make it relatively complex and hence expensive. It will therefore often be preferred
to install the flashing member with the third sheet portion at an angle, inclined
towards the second roof penetrating structure so that the joint between the first
and third sheet portions is above the joint between the second and third sheet portions.
According to the invention, in the mounted state, the angle of the third sheet portion
is 0-15 degrees in relation to the horizontal, which will generally be sufficient
to ensure a proper draining, 7,5 degrees being particularly preferred. A flashing
member designed for being arranged with its third sheet portion horizontally in a
roof with a pitch of 20 degrees will thus be useable in roofs with pitches of up to
35 degrees and only a few different versions of the gutter-like flashing members will
have to be kept on stock in order to cover all roof pitches. Angles of more than 15
degrees are of course possible, but will result in the flashing member not reaching
as deeply into the roof structure. This option is not part of the claimed invention.
[0011] Another factor which influences the possible use of a given flashing member is the
width of the third sheet portion. The wider it is, the deeper the flashing member
will reach into the roof. For common type installations of roof windows mounted in
traditional European roof structures a width of 120-160 mm, preferably 140 mm, is
presently considered expedient, and a width of 240-280 mm, preferably 260 mm, has
proven expedient when the roof pitch is less than 20 degrees. The exact optimal relationship
between width and angles in a given flashing member may be determined by experiments.
[0012] In some climate zones it is expedient to have insulating material arranged along
the outer sides of at least some of the window frame members. To give room for such
insulation or for other necessary components such as mounting brackets, wiring, motors
or the like, the gutter-like flashing member according to the invention comprises
a fourth sheet portion interconnecting the first and third sheet portions, said fourth
sheet portion being arranged at an angle to both the first sheet portion and the third
sheet portion. The provision of a fourth sheet portion may also serve aesthetic purposes
and it will be understood that the exact angles of the fourth sheet portion in relation
to the first and third sheet portions will of course depend on its purpose.
[0013] Likewise, it should be understood that the angle between the first and third sheet
portions referred to above applies with the fourth sheet portion, that the angle being
the angle between the planes defined by the first and third sheet portions, or, in
other words, between the imaginary continuations of the first and third sheet portions.
[0014] To minimize the risk of water penetrating into the roof structure, the flashing member
may further comprise a fifth sheet portion arranged at the end of the gutter perpendicularly
to the general longitudinal orientation of the flashing member, fifth sheet portions
preferably being provided at both ends of the gutter. It is noted, that these end
portions must of course leave a sufficient drainage passage, allowing water to get
out of the gutter even during heavy rain, so that it does not penetrate up underneath
the cladding members on the roof penetrating structures or into the roof structure
itself.
[0015] A particularly watertight structure is achieved by using a flashing member with a
sixth sheet portion at the end of the gutter and projecting in continuation of the
gutter, said sixth sheet portion being substantially perpendicular to the first and
second sheet portions and adapted for interconnecting side flashings members used
along the sides of the first and second roof penetrating structures, sixth sheet portions
preferably being provided at both ends of the gutter. In this way there will be no
joint between flashing members at the end of the gutter and the water-tightness will
hence be improved.
[0016] Each sixth sheet portion is preferably provided with engagement means adapted for
engagement with side flashing members. This will not only contribute to a tight and
durable joint between the gutter-like flashing member and the side flashing members,
but may also serve a guiding function during mounting. As an example, the sixth sheet
portion may be provided with longitudinally extending flanges made by bending or pressing
the flashing material up into ridges as is well known from side flashing members.
By arranging these ridges of the side flashing members and gutter-like flashing member
to ride on top of each other, where the respective flashing members overlap, the respective
flashing members are positioned precisely in relation to each other and the risk of
wrongful mounting is considerably reduced.
[0017] To further secure the tightness of the flashing assembly, the second sheet portion
may have a section adapted for overlapping an exterior upwards facing surface of the
second roof penetrating structure. The height of the second sheet portion then preferably
corresponds substantially to the distance between this exterior upwards facing surface
and the level of side flashing members used along at least one side members of the
second roof penetrating structure. Moreover, sixth sheet portions may be made to extend
up along the outer sides of one or both of the roof penetrating structures, so that
they extend up underneath cladding members arranged thereon.
[0018] To prevent water already at level with the side flashing members from entering the
gutter, the flashing member may further comprising a seventh sheet portion arranged
at the end of the gutter perpendicularly to the general longitudinal orientation of
the sheet flashing member and being adapted for being arranged along a side surface
of the first roof penetrating structure and extending past the first sheet portion
to partially span over the gutter, seventh sheet portions preferably being provided
at both ends of the gutter. The part extending along the side surface of the roof
penetrating structure will protect the roof penetrating structure from the water and
contribute to keeping the flashing member in place, and the part extending over the
gutter will guide the water downwards towards the side flashing member of the second,
lowermost roof penetrating structure, away from the gutter. This may be particularly
advantageous under windy conditions.
[0019] It is to be understood that the functions of the fifth, sixth and seventh sheet portions
are independent and that a flashing member according to the invention may have any
combination of such additional sheet portions, including for example only two types,
or that it may be provided without any of them.
[0020] The flashing member according to the invention may be made in several ways as will
be readily imaginable to the skilled person, but is preferably formed from a single
piece of material, preferably by folding, folding and drawing, deep drawing, compression
moulding or the like. In many cases this will result in rounded corners where the
first and second sheet portions meet the third sheet portions and possibly also elsewhere
on the flashing member. In such cases the reference to for example the position of
"the joint between the first and third sheet portions" is to be understood as the
position where these plate sections would have met had they been straight and jointed
in a sharp edge, i.e. where their imaginary continuations would intersect.
[0021] The material used for the flashing member is preferably a polymer or metal, such
as aluminium or aluminium alloys, which has proven well suited for use in the harsh
conditions occurring on a roof.
[0022] It is noted that even though the gutter-like flashing member is primarily described
as used between a pair of roof windows it may equally well be used between other types
of roof penetrating structures such as for example solar collectors, the windows serving
only as examples.
[0023] In the following the invention will be described with reference to the drawing, where:
Fig. 1 is a perspective, partially cut-away view of a pair of roof windows mounted
one above the other with a gutter-like flashing member between them,
Fig. 2 is cross-sectional and slightly perspective view along the line B-B in Fig.

members as well as pane, gaskets and hardware have been removed for clarity,
Fig. 3 is a closer view from a slightly different angle of the detail marked C in
Fig. 1,
Fig. 4 shows a flashing member seen from the exterior side,
Fig. 5 shows the flashing member in Fig. 4 from the lower end,
Fig. 6 shows the flashing member in Fig. 4 from the upper end,
Fig. 7 shows the flashing member in Fig. 4 from the left side,
Fig. 8 shows the flashing member in Fig. 4 in cross-section along the line A-A in
Fig. 4, and
Fig. 9 shows a cross-sectional sketch of a flashing member according to the invention.
[0024] In Fig. 1 a gutter-like flashing member 1 is shown mounted between two roof windows
2, 3 of which only the lowermost and uppermost part, respectively, is shown for the
sake of simplicity.
[0025] As may be seen most clearly from Fig. 2, the gutter-like flashing member comprises
a first sheet portion 11 arranged against the bottom frame member 21 of the uppermost
window 2 and a second sheet portion 12 arranged against the top frame member 32 of
the lowermost window 3. A third sheet portion 13 extends between the first and second
sheet portions 11, 12 and hence between the two windows 2, 3, forming the bottom of
the gutter.
[0026] The third sheet portion 13 is perpendicular neither to the first sheet portion 11
nor to the second sheet portion 12, but arranged at an angle, which at least partially
neutralizes the pitch of the roof so that the third sheet portion is close to horizontal,
while the first and second sheet portions are substantially perpendicular to the plane
of the roof. In the embodiment shown in Fig. 2, the interior angle f between the first
and third sheet portions is approximately 77 degrees and the angle s between the second
and third sheet portions is approximately 103 degrees. With a roof pitch of approximately
20 degrees, this results in the angle of the third sheet portion being approximately
7 degrees.
[0027] The width of the third portion 13, i.e. the distance between the first 11 and second
12 sheet portions, may vary depending amongst others on the overall size of the roof
penetrating structures, their installation dept, the pitch of the roof and the amount
of water to be expected in the climate zone, where the flashing member is to be used.
For standard size roof windows mounted as shown in Figs. 1-3 the width will typically
be 110-150 mm, preferably 125-140 mm, when the roof pitch is above 20 degrees, and
220-300 mm, preferably about 260 mm if the pitch is lower.
[0028] At the ends of the gutter fifth sheet portions 14 closing off the ends of the gutter
and sixth sheet portions 15 intended to be connected with side flashing members (not
shown) running along the sides of both windows 2, 3 are provided. These portions are
also referred to as end portions and side portions, respectively. In Figs. 1 and 2
only one end portion 14 is visible, but it is to be understood that end portions are
provided at both ends of the gutter, the flashing member being symmetric as may also
be seen from Figs. 4-6.
[0029] To provide a smooth and water-proof joint with the side flashing members, the side
portions 15 are arranged at level with these in the mounted state and furthermore
provided with three flanges 151, 152, 153 corresponding to those found on traditional
side flashing members. The original purpose of these flanges is to prevent water from
flowing sideways off the side flashing members and into the roof structure, but they
may also serve to keep individual flashing members in place in relation to each other.
Particularly the flanges 152, 153, which are here formed by folding or pressing longitudinal
U-shaped projections, are well-suited for this purpose, since the flange of an upper
flashing member may be arranged to ride over the corresponding flange on a flashing
member arranged further down the roof. If designed appropriately, this may even result
in a press-fitting, which will effectively lock the flashing members together.
[0030] The end portions 14 extend up to the level of the side portions 15 and hence the
side flashing members (not shown). This means that a pocket is formed at the first
sheet portion 11, where the third sheet portion 13 forming the bottom of the gutter
is located deeper in the roof. In the embodiment shown the dept of the gutter measured
from the level of the side portion 15 to the joint between the first and third sheet
portions of approximately 30 mm.
[0031] At the joint with the second sheet portions 12 the third sheet portion 13 is at level
with the flat section 154 of the side portion, leaving an exit passage 16 for water,
which will run through the gutter substantially as indicated with the arrows in Fig.
3. During heavy rain or when large amounts of melt water passes down over the roof,
the gutter may, however, be filled and water may then pass over the upper edges of
the end portions 14 and onto the side portions 15, thus effectively widening the exit
passage to cover a larger area.
[0032] To control the flow pattern of the water within the gutter-like flashing member,
water-guides may be provided, here illustrated by a raised section 17 a centre of
the third sheet portion 13. In this case the raised section will prevent or at least
hinder a flow in the longitudinal direction of the gutter and hence contribute to
an even distribution of the water on the two sides of the lowermost window. Other
possible embodiments of such water-guides are angled projections or grooves leading
the water outwards towards the exit passages 16.
[0033] In the embodiment shown in Figs 1-8 the flashing member is shown with a constant
cross-sectional shape over the entire length of the gutter between the two end portions
14, but it will be understood that this need not be the case. As an example, the third
sheet portion 13 be curved at least at the ends so as to form a smooth transition
with side portions 15 of the flashing member, in which case there would be no end
portions, and/or the width of the third sheet portion might gradually degrees towards
the ends so as to guide water towards the exit passages 16.
[0034] It is also important to make sure that water does not penetrate into the roof structure
along the longitudinal sides of the gutter formed by the first and second sheet portions
11, 12 during such peak load situations. Here, the second sheet portion 12 is therefore
provided with a section 121, which overlaps the exterior surface of the lowermost
window 3. In the embodiment shown, the overlapping section 121 is formed as a bend
edge hooking onto a top covering 33 on the lowermost window 3. It is of course also
possible to let the second sheet covering project over the exterior side of the frame
top member 32, but this involves two potential problems: Firstly, the mounting of
the gutter-like flashing member will be more complicated as roof windows are normally
supplied with pre-fitted top covering and, secondly, water overflowing the second
sheet portion will penetrate into the structure instead of being led up onto the covering
of the lowermost window.
[0035] Overflow is not as much of a problem at the uppermost window 2 due to the influence
of gravity and it will therefore usually be sufficient that the first sheet portion
11 is overlapped by the bottom frame covering 22 and bottom sash covering 23 of the
uppermost window 2 as shown in Fig. 2.
[0036] To further increase water-tightness the side portions 15 of the gutter-like flashing
member 1 are also provided with upstanding sections 155 and 156 extending along the
side frame members of the uppermost and lowermost windows 2, 3, respectively.
[0037] As may be seen particularly well in Fig. 1, the upstanding section 156 extending
along the lowermost window 3 is simply a continuation of the part of the second sheet
portion extending above the level of the side flashing members.
[0038] The upstanding section 155 extending along the uppermost window 2, however, may be
regarded as a seventh sheet portion, which protects the side frame member of window
and provides an overlap with a leg of the side flashing member (not shown) extending
along the side frame member. As may be seen in Figs. 1, 4 and 8 this upstanding section
155 also projects past the first sheet portion 11. The projecting part 157 guides
water coming from the side flashing member (not shown) at the uppermost window 2,
so that it does not enter the gutter but continues down the over the side section
15 of the gutter-like flashing member 1 and from there onto the side flashing member
at the lowermost window 3. This will be particularly advantageous during windy conditions
and the shape of the projecting part 157 may even be designed to help provide an advantageous
aerodynamic pattern at the lowermost corner of the uppermost window.
[0039] As may be seen in Figs 1, 3 and 4 the side portions 15 of the flashing members shown
on the drawing are wider at the end arranged opposite the uppermost window 2 than
at the end arranged opposite the lowermost window 3. This is to allow the use of traditional
standardized side flashing members, which are sometimes wider at the lowermost end
in order to allow a suitable discharge of water to the bottom flashing member or skirt
used at the bottom of a window arranged in solitaire or lowermost in a group. If,
however, side flashing members are of the same width at their top and bottom ends,
the side portions 15 of the gutter-like flashing member 1 may be of a constant width.
This may even be advantageous as the concentration of the flow of water, which results
from the narrowing cross-section of the side portions shown in the drawing and which
may force some of the water into the gutter, will then be avoided.
[0040] A gutter-like flashing member 1' according to the invention is shown in Fig. 9. This
flashing member has a first sheet portion 11', a second sheet portion 12' and a third
sheet portion 13' corresponding in function to those in the embodiments described
above. The first and third sheet portions are interconnected by a fourth sheet portion
113'. This results in the formation of a space 4' between the bottom frame member
21' of the uppermost window and the flashing member. This space may be filled with
insulating material and/or be used for housing hardware, electrical components or
the like (not shown).
[0041] The provision of the fourth sheet 113' of course also influences the overall appearance
of the flashing member 1' and the exact angles f", f''' of the fourth sheet portion
in relation to the first and third sheet portions 11', 13' may therefore be chosen
based on aesthetical considerations if not technical.
[0042] As indicated by the broken lines, the angle f between the first and second sheet
portions 11', 13' is still the same regardless of the provision of the fourth sheet
portion 113'.
[0043] In the above the disclosure has been explained with reference to the drawing showing
gutter-like flashing members 1, 1' used between two roof windows, but it is to be
understood that a similar flashing member may also be used between other roof penetrating
structures, such as solar collectors, as well as between two roof penetrating structures
of different types. Likewise, it is to be understood that a flashing member according
to the invention may also be made for use in groups, where roof penetrating structures
are arranged side-by-side, for example in a two-by-two configuration. In such cases
two flashing members may be arranged with overlapping side portions or one unitary
flashing member with two third sheet portions arranged end-to-end and a common side
portion between them may be provided.
