Asphalt composition hip and ridge cover
Abstract
An asphalt composition ridge cover and method of installing the
same whereby a decorative appearance somewhat resembling that of a
shake roof ridge is achieved. The ridge cover generally is a flat,
approximately rectangular piece of asphalt composition roofing
material, having a folded portion adjacent the center thereof,
thereby forming a region of increased thickness in a central
section thereof. When installed, the thickened portions force the
ridges to take the appearance of that of a shake shingle or tile
roof while maintaining double coverage as required in many
installations. Further features such as a self alignment and
spacing capability and provision for an unexposed nail are also
disclosed. A single coverage ridge cover having these same features
is also described.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of roofing, and more
particularly to roof ridge and hip covers.
2. Prior Art
Various types of roofing, and in particular, ridge covers, are well
known in the prior art and have been manufactured and installed in
substantially the same manner for a great number of years. In
general, the ridge cover selected for use on a particular roof is
selected in conjunction with the shingle or other roof covering, as
part of the roofing system. Consequently, in the following
discussion of the prior art, the considerations in choice of the
roofing system will be described, it being understood that a ridge
cover is generally selected for compatibility in appearance and
installation with a complete roofing system. Also, the present
invention ridge cover is particularly advantageous because of its
new and unique appearance and, therefore, the following discussion
of prior art is limited to those applications where appearance is a
substantial consideration.
Prior art roofing systems include asphalt composition shingles,
tile roofs, rock roofs (decorative rock scattered over an asphalt
covered asphalt composition sheet) and shake roofs. In general,
each of these types have certain features and disadvantages and the
choice for any particular installation is generally a compromise to
achieve the desired results. By way of example, a tile roof may be
a very attractive roof, but it is both an expensive and a heavy
roofing material, typically weighing as much as 900 pounds per 100
square feet. The weight of such roofs may require that the roof
structure itself be increased over that which would be used with
another type of roofing material and, consequently, the cost
associated with tile roofs may include an incremental cost due to
the increases of structural requirements in the building itself.
Such roofs, however, are both durable and attractive and are used
where these are prime considerations. Also, in some areas of the
country where there is a substantial hazard of fire due to hot
ashes originating from a nearby brush fire such roofs are used
because they are fire proof.
Rock roofs are often used for homes in some parts of the country
and are a reasonably good compromise between cost and appearance.
This type of roof is generally limited to low pitch roofs since the
rocks are not all physically secured to the underlying asphalt.
Also, the rocks tend to become scattered with time because of the
effects of high winds, heavy rains or the sweeping effects of
branches on neighboring trees and, therefore, must be replaced or
replenished occasionally to maintain the desired appearance.
Shake roofs are roofs made up of tapered wooden strips nailed to
the roof much like shingles and are popular in parts of this
country because of their highly attractive appearance and because
they esthetically conform to many types of building construction.
This type of roof is somewhat less expensive than a tile roof and
is much lighter, characteristically having weights of approximately
450 pounds per 100 square feet. However, such a roof is not as
durable as most other types of roofs since it is subjected to
deterioration from environmental exposure and the individual wooden
members are apt to crack when walked on, and to thereafter leak.
Furthermore, unless specially treated such roofs are highly
inflammable and create a substantial fire hazard whenever the roof
may be exposed to hot ashes originating from a neighboring
fire.
An asphalt composition roof made up of individual shingles is a
relatively durable, light-weight and inexpensive roof. Such a roof
may have a weight of approximately 235 pounds per hundred square
feet and is fairly easily and quickly installed. The asphalt is not
easily ignited and fire resulting from hot ashes falling on the
roof is further inhibited by the granular surface on such roofs.
However, this type of roof is a very flat and bland type of roof,
the shingles having little thickness and distinctive character to
create an attractive appearance. Though such shingles may be made
with a variety of color granules on the surface, thereby creating a
reasonable choice of colors for the final roof, and the individual
shingles create a reasonably attractive pattern on the roof, such a
roof is a roof with pattern and color without dimension, since the
individual shingles are only on the order of one-eighth to
three-sixteenths of an inch thick, and little depth or dimension is
given by the overlap of one shingle by another. Consequently,
though the appearance is the only substantial negative factor
associated with such roofs, they are not commonly used in
installations where considerations of appearance outweigh
considerations of cost.
SUMMARY OF THE INVENTION
The present invention is employed in asphalt composition ridge
covers to create an appearance similar to that of a shake shingle
roof. The invention generally is formed by creating a thickened
portion near the center of asphalt composition ridge covers. The
first ridge cover is placed on the ridge in a normal manner. The
second ridge cover is placed such that one end protrudes slightly
over the thickened area and the other end extends beyond the top of
the first ridge cover, thereby elevating the protruding end of the
ridge cover. Each additional ridge cover is deployed in a manner
similar to the preceding ridge cover to provide full double
coverage. The ridge covers appear, at the exposed end, 5 to 6 times
as thick as the conventional asphalt shingle, creating an
attractive appearance by adding a dimensional characteristic to the
ridge cover while maintaining full double coverage. A suitable
cement may be used to allow installation with an unexposed nail,
and a folded lip at the exposed end serves as an installation
guide.
In the presently preferred embodiment of the invention, the
increased thickness is formed by slitting and scoring an asphalt
composition ridge cover such that it may be folded to provide the
increased thickness, while allowing the ridge cover to be shaped so
as to be installed on a ridge of a roof.

DETAILED DESCRIPTION OF THE INVENTION
First referring to FIG. 1, an illustration of the present invention
Ridge Cover, as installed on a typical roof, may be seen. It is to
be understood that the phrase Ridge Cover, as used herein, is used
in the broad sense to include hip covers and the like, and is used
merely as a convenient phrase for identifying all such covers. It
may be seen that the ridge 20 as well as the hip 22 is
characterized by a pleasant physical appearance as a result of the
raising of the outward extending end of the ridge covers to provide
an appearance more like a shake roof ridge cover. The manner in
which this is achieved in the preferred embodiment is illustrated
in FIG. 2, which is a cross section taken along line 2--2 of FIG.
1. Each ridge cover 24 (except the lowest one) in this embodiment
is comprised of a first section 26 and a second section 28,
integrally connected in the center by a plurality of folds in
region 30. For convenience in FIG. 2 in separating the various
sections of the various covers, the respective sections 26 and 28
have a letter following the numerical designation so as to better
identify the particular cover for which the respective section
forms a part thereof. Thus the first ridge cover is identified by
section 26a (its section 26a having been removed because it is the
lowest cover on the ridge) and a folded region in region 30a. The
second cover is identified by sections 26b and 28b coupled by a
folded region 30b. Of course further installation proceeds onward
up the hip or toward the center or other inward location of the
ridge.
Now referring to FIG. 5, the planform of each of the ridge covers
before it is folded into the desired form may be seen. In the
preferred embodiment, the ridge cover is formed of conventional
asphalt composition roofing material characterized by a first layer
of asphalt impregnated fibrous material, a second layer of asphalt
thereover and a final layer of granules over the layer of asphalt.
While any weight material may be used, 90 lb. per square material
has been used in the preferred embodiment with most pleasing
results.
Rolls of asphalt composition material are cut so as to provide the
basic trapezoidal form of the ridge cover before folding, as shown
in FIG. 5, which in the preferred embodiment has a width at the
narrow end 32 of approximately 6 inches, a width at the wider end
34 of approximately 8 inches, and a total length of approximately
30 inches. The various dashed lines, as will be subsequently more
fully explained, represent the ultimate fold lines shown in FIG. 5,
identified for purposes of explanation and identification of the
relative proportions of the ridge cover. In addition to the basic
form shown in FIG. 5, it is preferable when cutting this form to
also slice a T-shaped form, generally in the center of the ridge
cover, comprised of a longitudinal cut 36 with a transverse slice
38 at one end thereof having a length of approximately 13/8 inches.
In these cuts it is not necessary that any material be removed
though the cuts should extend through the asphalt composition
material, particularly the fibrous base layer thereof, so that in
the folding operations to follow the material may readily separate
along those cuts. Also, for reasons which will subsequently become
apparent, a notch 60 is cut in the larger end of the cover (again
removal of material not being required).
In this embodiment, section 26 up to the first fold line 40 is
approximately 13 inches long, with second fold line 42 being
located approximately 13/8 inches from fold line 40, fold line 44
being located approximately 13/8 inches from fold line 42, and fold
line 46 being located approximately 23/8 inches from fold line 44.
Accordingly it will be noted that at least in the preferred
embodiment the fold lines are unequally spaced, so that the folds
do not lay one upon another, but instead are staggered, in part to
avoid any problems that might be encountered as a result of the
inability to fold the asphalt composition material back upon
itself, particularly when folding the material so that the fibrous
layer is on the outside of the fold, as the fibrous layer exhibits
little ability to stretch during the folding process. The effect of
the staggering of the folds may be seen in FIG. 2, by way of
example. There is also one additional fold line 48 approximately
one-half inch from the larger end 34.
The various folds to be made in the cover of FIG. 5 may readily be
made by automatic equipment operating in synchronism with the
cutters cutting out the basic form for the ridge cover, in which
case the various fold lines 40 through 48 of FIG. 5 may not be
marked or otherwise identified on the cover prior to bending. On
the other hand, it may be convenient for the fold lines to be
identified on the cover before folding by such means as scoring or
indenting the granule and asphalt layer so as to define lines of
reduced resistance to bending thereby providing the cover with a
natural tendency to bend first along those lines. Short slits have
also been used to define lines of reduced resistance to bending,
though scoring is preferred as it is easily accomplished and
removes the granules and some asphalt along predetermined lines,
thereby not only defining the fold lines but also tending to avoid
material build-up in the fold when the cover is folded with the
fibrous layer to the outside of the fold.
In any event, the ridge cover is bent into the form shown at FIG.
6, which is a cross section taken along the longitudinal center
line of a folded cover. It will be noted that the large end 34 is
bent under to form a forward lip 50, and that the various folds in
region 30 are staggered one to another so as to more accurately
achieve a build up characterized by the multiple layer thickness of
the material. Also it will be noted that the transverse slit 38 is
disposed just over the end of the longitudinal slit 36 on fold line
46.
The planform of the folded cover may be seen in FIG. 3. It will be
noted that as a result of the combination of the continuous taper
of the cover along its length and the multiple folds in the central
region, there is a small but definite difference in the width of
section 28 and section 26 in the region 30. This could be
eliminated by eliminating the taper between fold lines 40 and 46 in
FIG. 5, though the step width change is not great, and in fact is
preferred, as it tends to insure that section 28 of one cover when
installed will at least come to the edges of region 30 of the
underlying cover, thereby assuring the best possible visual effect
in the finished ridge.
In the preferred embodiment, an adhesive 52 is applied to the
undersurface of the larger end of the ridge cover. This adhesive is
of the type well known in the art, such as the asphalt seal
manufactured by Asphalt Products Oil Corp. of Long Beach, Calif.
The adhesive is placed in this region, so that after the ridge
cover is in place heat from the sun will cause the adhesive to flow
to secure the forward edge of the ridge cover to the top surface of
the underlying ridge cover. This avoids the necessity of nailing
through the larger end of the ridge cover, and as shall be
subsequently explained, allows for installation without using
exposed nails. The adhesive 52 should cover a sufficiently large
area so as to provide adequate bonding in a manner similar to the
bonding typically used for asphalt composition shingles themselves.
The adhesive 52 may be applied after the ridge cover is folded to
the form shown in FIG. 6 or may be applied to the cover before
folding, perhaps even as early as prior to cutting the material
into the shape shown in FIG. 5. In that regard, the folds in the
ridge cover tend to unfold easily when the cover is warm if not
secured in the folded position. Therefor a staple or other securing
means may be provided through the folded region 30, or the adhesive
may be put on at least some surfaces adjacent the fold lines to
secure the material in the folded condition.
Conventional ridge covers are cut and packaged flat and are then
bent along the longitudinal ridge line by the installer. This may
be done with respect to the present invention also, as bending the
ridge cover of the present invention along the ridge line is not
significantly more difficult than bending a conventional ridge
cover because of the fact that the cover is sliced along the ridge
line in any regions having more than one thickness of cover
material. However in cold weather, asphalt composition material is
difficult to bend, and of course tends to bend about an axis
located in the bottom fibrous layer so that the upper layers of
asphalt and granules tend to crack and separate, depending upon the
extent of the bend. Therefore in the preferred embodiment of the
present invention, the ridge cover is folded along the longitudinal
ridge line into the form shown in FIG. 7, and is shipped in that
folded condition by bending or folding the ridge cover along the
ridge line at the factory. There is little tendency for the asphalt
layer and granule layer to crack and separate when bent while warm.
Also in order to facilitate bending, the transverse slit 38 allows
the resulting corners 56 and 58 to project slightly outward with
respect to the portion of section 26 immediately adjacent thereto
so that the folded section 26 and folded section 28 may fold into a
full 180.degree. fold over their entire length, with the transverse
slit 38 providing for local distortion, caused by the accumulation
of thickness in the folded region 30. Also the folded lip 50 does
not interfere with the longitudinal folding of the cover because of
the small slot 60 (FIG. 5) provided in the ridge cover as cut.
Folded lip 50, however, in the preferred embodiment, does achieve a
first desirable result by providing spacing to hold the region of
section 28 covered by adhesive 52 sufficiently apart so that
oppositely disposed adhesive coated areas will not touch to cement
the ridge cover into the folded position. Of course as an alternate
or in addition to the lip 50, wax paper or the like may be placed
between the two adhesive coated areas to prevent their adhering to
each other, or adhesive and wax coated regions may be disposed on
each side of the fold so that when the ridge cover is folded along
the ridge line as shown in FIG. 7, the adhesive and wax coated
areas of one side of the ridge cover abut the wax and adhesive
coated areas, respectively, of the other side of the ridge cover.
(Longitudinal strips of adhesive and wax may be used and are easily
applied by automatic equipment.) Also, if desired the ridge fold
line 54 may be again coated with adhesive (asphalt) and a new layer
of granules applied, so that even slight separation of the granules
which may occur during the folding will not affect the end product
at all. This is done in the preferred embodiment to provide extra
protection on the ridge line. However it should be noted that
folding the ridge cover at the factory will result in less cracking
and separation of the granule layer than is normally encountered
when installing prior art ridge covers under cooler conditions, and
unfolding to the ridge angle on installation will generally close
such cracks.
The ridge covers are then packaged so as to stand on edge, one
beside the other, with the layer thereabove being supported by the
thickened regions created by the folds. On installation the ridge
covers are removed from the package, opened to the ridge angle and
installed in a reasonably conventional manner. It should be noted
that even in relatively cool weather the ridge covers will not
crack along the ridge line for the reason that they are being
opened rather than folded, thereby tending to close rather than
open any cracks. Of course the ridge covers may be nailed to the
roof through the section 28 adjacent the lip 50. A nail in this
region, however, will result in an exposed nail head, as that
section of a ridge cover comprises the outer or final cover layer.
As an alternate, each cover may be nailed to the roof through the
thickened region 30, such as by the use of nails 60. Thus the nail
head may be covered by the section 28 of the next cover to be
installed, with the adhesive 52 securing section 28 of each cover
to the folded region therebelow upon exposure of the assembled
ridge cover to the heat of the sun. However, because of the many
thicknesses of asphalt composition material in the folded region,
the nails are more difficult to drive through this increased
thickness, particularly in cool weather. Accordingly each ridge
cover may be nailed to the roof just behind the folded region 30,
such as by way of example, by the use of nails 62, with the
adhesive under the forward end of section 28 of each ridge cover
securing that end of the ridge cover in position as previously
explained.
Aside from holding the adhesive coated portions of the ridge cover
in separation, the folded lip 50 also provides a convenient
locating gage. Thus as illustrated in FIG. 4, after the first ridge
cover 20a is fastened to the roof, the second ridge cover 20b may
be quickly unfolded and placed thereover with the lip 50b locating
against the folded edge 70a to accurately align and space the
covers. Similarly the next cover 20c is installed with the lip 50c
locating against the fold 70b of cover 20b etc. (see FIG. 2 also),
with installation proceeding rapidly and accurately along the ridge
or up the hip.
Now referring to FIG. 9, an alternate embodiment ridge cover and a
cross section similar to that of FIG. 2 illustrating the
installation of the alternate embodiment may be seen. In this
embodiment there is a single S-type fold in region 130 separating
the smaller end section 126 and the larger end section 128, with an
additional S-shaped fold in addition to the lip 150 at the larger
end 134 of the ridge cover. In this alternate embodiment, adhesive
152 may be used to secure the outwardly extending end of the ridge
cover as before, and if the adhesive 152 is applied to the ridge
cover before folding it may also form an adhesive to secure the
first fold of the S-shaped fold and end 134. In this embodiment
slits equivalent to slit 36 and 38 in the central fold region 130
are used, and in addition a notch, such as notch 60 of FIG. 5, is
used extending not only through the lip region 150 but also through
all parts except the top layer of section 128 so as to allow the
easy bending of the ridge cover to the ridge angle. In this
embodiment the ridge cover would normally be shipped flat rather
than being folded as shown in FIG. 7, as the top of section 128
adjacent end 134 preferably is not slit and the accumulation of
thickness thereunder, while allowing the easy bending of the cover
to the ridge angle as a result of the slot thereunder, may not be
readily bent to the full 180.degree. as shown in FIG. 7. Also, it
should be noted that if desired, nailing may be achieved through
the folded region 130 somewhat easier than through the folded
region 30 of the previous embodiment for the reason that there are
only three layers of asphalt composition material rather than the
five layers of the previous embodiment.
It will be noted that the specific embodiments of the present
invention shown and described herein are characterized by a
thickened region approximately midway along the length of the cover
and further by the provision of a lip at the larger end of the
cover to aid in the placement and location of each successive cover
in an installation. The covers further provide for full double
coverage through the use of unexposed nails. (Though if desired,
section 26 may be eliminated as in FIG. 10 to provide a single
coverage cover.) The greatly enhanced visual appearance of the
finished roof is achieved in a simple and efficient manner without
the use of any additional materials, loose parts, etc., with the
covers being readily manufactured by automatic equipment from
conventional material in an inexpensive manner. Thus, while
separate blocks or wedges of other materials, such as plastic and
the like, could be fastened to an otherwise flat ridge cover to
build up the thickness, such a cover requires the fabrication of
special parts and the accurate placement and fastening of these
special parts to the asphalt composition material, thereby
resulting in higher tooling costs and higher costs of materials for
the manufacturer.
Thus, there has been described herein a hip and ridge cover having
greatly enhanced visual appearance, which may be readily
manufactured with automatic equipment from conventional asphalt
composition roof materials and easily and accurately installed with
full double coverage using unexposed nails. Of course, while the
present invention has been disclosed and described with respect to
two specific embodiments thereof, it will be understood by those
skilled in the art that various changes in form and detail may be
readily made therein without departing from the spirit and scope of
the present invention.
