Description
FIELD OF THE INVENTION
[0001] The invention relates to roofing shingles, and more
particularly to a shingle that has a folding tab on at least one
side to prevent, when secured to a roof, wind from entering under
the shingle and removing it from the roof.
PRIORITY
[0002] Priority is claimed from Provisional Application No.
60/660,030, filed Mar. 9, 2005.
BACKGROUND OF THE INVENTION
[0003] In general roofing shingles are secured to a roof with tacks
that attached the shingle at the upward side of the shingle as the
shingles are mounted on the roof, beginning at the lower edge of
the roof and progressing upward. The lower edges of the singles are
not attached allowing a strong wind to enter under the shingle,
blowing it upward and at times removing the shingle from the
roof.
[0004] The following patents are describe to give a general
overview of roofing inventions and are not intended to present a
disclosure statement.
[0005] U.S. Pat. No. 4,672,790, entitled Multi-piece asphalt
composition roofing system, describes an asphalt composition roof
covering system for roofing and reroofing. The covering system is
comprised of a base and a plurality of tabs cut from standard rolls
of asphalt composition material. The base has first, second and
third regions separated by a first and second fold so as to provide
a "Z" shape. The plurality of folded tabs are inserted into the
third region of the base to give a three-dimensional appearance. In
addition, when the system is used for reroofing over existing shake
roofs, a spacer is provided along the inclined plane of a shingle
to raise the base.
[0006] U.S. Pat. No. 4,717,614, shows a rectangular shingle sheet
having a butt portion which is longitudinally divided into spaced
apart tab segments and an undivided headlap portion which is 1.3 to
1.5 times higher than the outward extensions of said tab segments
in said butt portion; said butt portion and headlap portion
carrying an asphaltic backing of varying thickness Wherein the
upper area of the headlap portion which is of a height
approximately equal to that of the butt portion is coated with an
asphaltic backing of between about 5 and about 15 mils thickness
and the remaining lower area of the headlap portion and the entire
butt portion is uniformly coated with an asphaltic backing of
between about 20 and about 75 mils thickness. In one embodiment,
the shingle is a composite roofing shingle comprising a shingle
sheet having a butt portion which is longitudinally divided into
tab segments spaced apart by between about 0.5 and about 1.5 their
width and an undivided headlap portion which is between about 1.3
and about 1.5 times the height of the outward extension of the tab
segments in the butt portion; said butt portion and headlap portion
carrying an asphaltic backing of varying thickness as described
above, and a separate elongated strip underlying the tab segments
which fills the space between the tabs and is secured to the
shingle sheet in a position underlying the thickened asphalt coated
area of said sheet. The invention also includes the process for the
manufacture of the shingles of this invention.
[0007] U.S. Pat. No. 4,848,057, describes a roofing shingle
consisting of composite plies of thin sheet material adhered
together by asphalt having exposed areas with or without cut outs
between tabs, and a flexible region at the end top of the exposed
area. The top end of the cut outs may lie in this flexible
region.
SUMMARY OF THE INVENTION
[0008] The invention is a roofing shingle that has a folding
nail-down or securing strip added to the edge of the shingle that
is placed on the lower or down edge of the shingle. This folding
nail-down strip is attached to the roof and then the shingle is
folded up over the stip. After a row of shingles have been secured
across the roof, then a second (and additional rows thereafter) are
placed on the top edge of the first row. The folding nail-down
strip is attached to the roof over the top edge of the first row
and then the shingle is folded up and over covering the attachment
strip. Rows are similarly added until the roof is completely
shingled. The shingles are place such that there are three rows of
nails holding down each single, A first row of nails is from the
nail down stip of the first shingle. The second row of shingles is
place over the first row so that the nail down strip is
approximately over the center of the first row. The third row of
shingles is placed over the second row and over the top end of the
first row, resulting in each row of shingles being secured to the
roof at three places, each place being a nail-down strip of three
different shingles.
[0009] The technical advance represented by the invention as well
as the objects thereof will become apparent from the following
description of a preferred embodiment of the invention when
considered in conjunction with the accompanying drawings, and the
novel features set forth in the appended claims.

DESCRIPTION OF A PREFERRED EMBODIMENT
[0017] FIG. 1 is an example of a roofing shingle 10 according to
the present invention. Shingle 10 has a main portion 11, which may
be a three tab shingle, and a nail down strip 13 that is attached
to part 11 by a flexible and bendable strip 13 between part 11 and
nail down strip 13. Strip 13 can be an integral portion of the
shingle, separated by a reduced thickness of the shingle that is
flexible and will bend with out tearing or breaking, or may be a
strip attached by a flexible material, for example, plastic, mesh
screen wire, or a glass fiber reenforced material.
[0018] FIG. 2 is a side view showing the shingle 10 with part 11
and strip 12, connected by reduced thickness stip 13. In FIG. 3,
strip 12 is shown folded up, which when mounted would be secured to
the roof and under the edge of part 11.
[0019] FIG. 4 shows a variation of the shingle with a main part 20
and a nail down strip 21. Strip 21 is attached to shingle 20 by a
flexible strip 22. Strip 22 may be, for example, plastic, mesh
screen wire, or a glass fiber reenforced material. In FIG. 5, strip
21 is shown moved adjacent to shingle 20 as it would be when the
shingle is attached to a roof.
[0020] The roof shingle usually consist of a base sheet, a
flexible, reinforced strip glued onto the base sheet. Granules are
applied to one side of the shingle, and asphalt may be applied to
the other side. The nail down strip is either an integral part of
the shingle, but separated from the main part of the shingle by a
reduced area, or the nail down strip may be a separate part
attached to the mail part by a reinforcement strip, allowing the
nail down part to be folded.
[0021] FIG. 6 shows a part of a shingle 10 wherein the nail down
strip 12 has been attached to a roof decking 9. In this example,
roofing tacks 15 are used to secure the nail down strip 12 to the
roof deck 9. The shingle part 11 is then folded up and over the
nail down strip 12.
[0022] FIG. 7 shows a partial roof deck 9, with a starter strip 17
that extends along under the first row of shingles at the edge of
the roof 18. Usually, the roof is cover with a felt or tar paper
prior to installing the starter strip and the roofing shingles.
Since each successive rows of shingles are partially off set from
the preceding row, some of the shingles need to be cut into smaller
lengths. On the first row (R1) of shingles, the nail down strip 12
is secured to the roof deck with roofing tacks 15. The folded edge
13 of the shingle is aligned with the edge of the roof 18. The
shingle part 11 is then folded over the nail down strip 12. This is
continued along the edge of the roof until the first row of
shingles are in place.
[0023] A second row (R2)of shingles is then secured to the roof so
that the nail down strip of the second row overlaps the first row
of shingles, and is placed approximately in the middle of the first
row (R1). This secures the nail down strip of the second row of
shingles over the first row of shingles.
[0024] A third row (R3) of shingles is placed over the second row
at approximately the middle of the second row (R2) and over the
upper edge of the first row (R1). In this manner, each row of
shingles is secured to the roof in three places, the front or lower
edge, the middle and the upper edge. This prevents the roof
shingles from being blown away in very high winds. A coating of tar
adhesive may be applied to the bottom of each shingle to further
secure it to the roof or felt paper there under.
[0025] This process is continued up the roof, adding overlapping
rows of shingles until the roofing process is completed. Both the
lower edge, middle, and upper edge of each row of shingles is
firmly secured preventing wind from blowing the lower edge of the
shingles upward, or completely blowing the shingles from the
roof.
