`
`BUILDING PANEL WITH IMPERMEABLE
`SURFACE LAYER
`FIELD OF THE INVENTION
`0001. The present invention relates generally to improve
`ments in building panels typically used for roof construction
`and weatherproofing. More particularly, the present inven
`tion provides an improved roofing panel that allows for an
`improved roofing System and method for construction. Each
`panel is prefabricated with an impermeable Surface layer
`bonded to the panel with one or more overlapping edges.
`Thus, the impermeable Surface layer of each panel extends
`onto the Surface layer of an adjacent panel to provide a
`weather resistant roof that eliminates the construction Step of
`Separately installing a water resistant layer Such as tar paper
`or other impermeable materials while on the rooftop.
`BACKGROUND OF THE INVENTION
`0002 Weather resistant roofing is a crucial requirement
`for any Successful building, and a number of methods have
`been used. In conventional home construction, roofs are
`often constructed by laying a weather resistant felt liner on
`a roofing deck, then applying shingles and long Strips of
`liner that overlap the Shingles. This process is expensive and
`time consuming, and may create a Safety risk based on the
`additional time workers must spend on the roof. Addition
`ally, nail holes can allow leaks over time, and wind uplift
`forces can readily damage the shingles.
`0003. Other roofing systems use panels to provide for
`quicker installation. Metal panels which overlap or interlock
`are often used, however heat induced expansion and con
`traction of the metal can lead to cracks or gaps through
`which moisture may enter the building. Metal roofing panels
`are also difficult to shape for fitting corners and angles.
`0004 Another type of roofing system is the single-ply
`membrane roof, in which an insulation barrier like foam or
`Wood is installed in panels on the roofing deck, and then
`impermeable sheets of a polymeric material Such as ethylene
`propylene diene rubber (EPDM) are installed over the
`insulation panels. Single-ply roofs allow for faster construc
`tion than shingled roofs, however there are difficulties in
`attaching the membrane to the insulation panels. Mechani
`cally fastening large sheets of membrane to the roofing deck
`requires careful labor and createS problems of wind uplift
`and water leakage. Likewise, using adhesives over the entire
`Surface requires additional time and expense. Additionally,
`an area around the edges of the membrane sheets must often
`be cleaned in order to create a good Seal when adjacent
`sheets are attached to one another. Plus, all construction
`must take place on the rooftop itself, creating difficult
`working conditions and a Safety hazard.
`0005. As such, because of the necessity of having a
`weather resistant roof and because of the time and expense
`involved in building one, there is a need for an improved
`roofing material and method for installation that is efficient,
`quick, and reliable. Also, because construction often takes
`place on the rooftop, there is a need for a roofing System and
`construction method that reduce the time workerS Spend on
`the roof and thus improve Safety.
`SUMMARY OF THE INVENTION
`0006 The present invention is therefore directed to a
`weather resistant roofing panel, a roofing System using this
`panel, and a method for construction.
`
`0007 One aspect of the present invention relates to
`providing a prefabricated roofing panel that is cost effective
`to produce and install. Another aspect relates to an improved
`roofing System that may be constructed more efficiently with
`less overall cost and greater reliability while providing
`protection from the weather in a shorter installation time.
`0008 Another aspect of this invention is to provide a
`roofing panel that has an impermeable Surface layer bonded
`to each panel prior to its use in construction of a roof. An
`additional aspect is to eliminate the need to attach weather
`resistant sheets at the construction site while on the rooftop.
`A further aspect of this invention is to provide a panel with
`an impermeable Surface layer that may be easily joined to
`adjacent panels and Sealed. Yet another aspect is to provide
`a roofing panel that may be joined to adjacent panels and
`Sealed without the need for additional roofing components.
`Still another aspect is to provide a roofing panel in which
`nails are not needed to attach the impermeable Surface layer.
`Additionally, the panel may include an impermeable Surface
`layer having a textured or prepared Surface that provides
`greater traction for the worker as he walks on the Surface
`during construction. A further aspect is to provide an imper
`meable Surface layer that reduces wrinkles. An additional
`aspect is to provide a Surface layer made from coated paper
`to facilitate installation, weatherproofing, repairing, and
`bonding and to reduce expense.
`0009. Another aspect of this invention is to provide a
`Versatile roofing panel that may be easily cut or altered to fit
`any roof shape desired. Further aspects Stem from providing
`a roofing panel made from Oriented Strand Board (OSB).
`OSB functions as insulation, provides structural stability,
`reduces expenses, and may be easily cut to fit different roof
`shapes. Yet another aspect of the present invention is to
`provide a roofing panel that is resistant to wind uplift and
`that is easy to repair.

`
`sectional view of the roofing panel in FIG. 1. In FIG. 1, a
`roofing panel 1 is provided that includes a panel body 2 and
`a weather resistant Surface layer 3 having a first weather
`resistant tab 4 and a second weather resistant tab 5. The
`weather resistant surface layer 3 is bonded to the panel body
`2. The first tab 4 extends beyond a first edge 6 of the panel
`body 2, and the Second tab 5 extends beyond a Second edge
`7 of the panel body 2. When panels are installed as illus
`trated in FIG. 4, the first and second tabs 4, 5 overlap the
`Surface layerS 3 of adjacent panels and thus may be bonded
`or fastened to create a Seal over the line of abutment of the
`adjacent panels. Thus, the portions of the first and Second
`tabs 4, 5 that extend beyond the edges of the panel body are
`preferably connected, as shown in FIGS. 1 and 4, so as to
`create a continuous weather resistant Surface without gaps at
`the panel corners.
`0.018. Additionally, in a further embodiment, the roofing
`panels may be made So that the weather resistant Surface
`layer 3 is not bonded to the panel body 2 in a region along
`the edges of the panel So that clips may be installed to hold
`adjacent panels. In this manner, the consistency of the
`weather resistant Surface layer 3 is not compromised, and the
`weather resistant Surface layer 3 may overlap the clips.
`Furthermore, with this embodiment, the weather resistant
`Surface layer 3 may be lifted up along the edges of the panel
`body 2 to allow for nails to be driven through roofing panel
`without penetrating the weather resistant Surface layer 3.
`0019. It should be understood that the presently preferred
`use of the invention is for construction of roofs, but the
`panels may also be used for other construction purposes
`Such as exterior wall sheathing, flooring, decking and other
`uses when an extended weather resistant Surface is desired.
`0020. In accordance with the present invention, the roof
`ing panel 1 illustrated by FIG. 1 eliminates the need to
`Separately install a weather resistant Surface layer 2 to
`roofing panels 1 after the panels have been installed. Instead,
`the roofing panels 1 of the present invention are prefabri
`cated with a weather resistant Surface layer 2 attached. The
`first and Second tabS 4, 5 provide a waterproof layer acroSS
`adjacent panel units by the use of an overlapping relation
`ship. These features eliminate construction StepS and com
`ponents, thus Saving time and expense and improving Safety.
`0021 One of skill in the art will also recognize that the
`panel body 2 can be made of any desired material and can
`be selected to function as insulation as well as simply
`Support for the roof. For example, composite wood Such as
`Oriented Strand Board (OSB) or plywood may be used for
`the panel body to provide insulation, Structural Support, and
`Stability. For example, a panel of the present invention made
`from OSB would typically have a thickness suitable for the
`particular purpose Such as /4 inch to 1 inch and may be 4 feet
`by 8 feet or 4 feet by 12 feet in size. The tabs 4, 5 may extend
`beyond the edge of the panel body 2 an appropriate amount
`Such as % inch to 2 inches typically. Furthermore the weight
`of the OSB panel body 2 increases the panels resistance to
`wind uplift when the surface layer 3 is bonded tightly to the
`panel. An OSB panel body 2 also allows for greater versa
`tility in roof construction as the panel body 2 may easily be
`cut to fit the dimensions of the roof. Additionally, OSB also
`helps to reduce cost. One of skill in the art will recognize
`that other types of materials may also be used depending
`upon the particular application. One of skill in the art will
`
`also recognize that conventional plywood, foam, polymers,
`or other materials may also be used for the panel body 2.
`0022. One embodiment of the present invention may use
`coated paper as the weather resistant Surface layer 3. The
`paper may be coated on one Surface with any water resistant
`material Such as tar, felt, polyethylene, or plastic. The
`uncoated Surface of the paper may be readily bonded with an
`acceptable adhesive to the surface of the OSB panel body 2.
`The coating also makes the paper Substantially impermeable
`to water and can provide traction for walking on the roof.
`The first and second tabs 4, 5 may then be formed by simply
`extending the length of the paper over the first and Second
`edges 6, 7, respectively, of the panel body 2 during fabri
`cation of the panels. Thus, the first and second tabs 4, 5 may
`be prefabricated onto the panel without using additional
`Sealing components. Using coated paper also provides first
`and second tabs 4, 5 that are flexible, easy to work with, and
`easy to cut or trim while being resistant to tearing or
`destruction. Furthermore, coated paper may reduce the cost
`of the roofing panel. However, one of skill in the art will
`recognize that the weather resistant Surface layer and
`weather resistant tabs of this invention may be made using
`numerous weather resistant materials, including polymeric
`membranes and paper coated with other appropriate mate
`rials or particles. Alternatively, panels may be prefabricated
`with separate tabs pre-bonded to the surface layer 3. Thus,
`tabs could be made from different material if desired.
`0023 The panel in FIG. 1 may be assembled into a
`paneling System for use in roofing as is shown in the
`embodiment of this invention represented by FIGS. 4 and
`5. FIG. 4 shows a paneling system in which panels are
`positioned adjacent to one another with their edges abutting.
`FIG. 5 shows this paneling system assembled on a roof. The
`paneling System of FIG. 4 may be constructed by installing
`a Series of adjacent rows. Initially, row 12 is constructed by
`the Steps of first positioning panel 8, then positioning a
`Second panel 9 So that edge 14 of panel 8 abuts against edge
`6 of panel 9. The first tab. 4 of panel 9 may then overlap a
`portion of panel 8. The second tab of panel 9 has been
`removed because panel 9 is on an end row. Likewise, the
`first and second tabs of panel 8 have been removed because
`it is an end panel. Alternatively, tabs on end panels can be
`folded onto the panel body 2 or attached to adjacent Struc
`tures if desired. End panels may also be cut or trimmed to
`fit the dimensions of any roof. Additional panels (not shown)
`may also be added to row 12 as desired according to the
`above method.
`0024) Next, row 13 of FIG. 4 is constructed by position
`ing panel 10 adjacent panel 8 so that edge 7 of panel 10 abuts
`edge 15 of panel 8 and second tab 5 of panel 10 overlaps a
`portion of panel 8. Then panel 11 is positioned adjacent to
`and abutting panel 10 and panel 9 so that the first and second
`tabs 4, 5 of panel 11 Overlap a portion of the adjacent panels.
`Additional panels and rows of panels (not shown) may be
`added to the paneling assembly in accordance with the
`above steps. The first and second tabs 4, 5 of each panel may
`then overlap a portion of the adjacent panels and, if desired,
`be attached to the Surface layerS 3 of the adjacent panels.
`One of skill in the art will also recognize that the panels can
`be installed in a different Sequence as long as the tabs
`overlap adjacent panels. Furthermore, although the panels of
`this invention may be effectively oriented in many positions,
`if a roof is sloped, then overlapping the Second tab in a

`
`downwards direction will facilitate the flow of water over
`the panels. Additionally, if the weather resistant Surface
`layer 3 of each panel is not bonded to the panel body 2 along
`its edges, then clips can be installed against the panel body
`2, underneath the weather resistant Surface layer 3 and
`underneath the Overlapping tabs 4, 5, to hold adjacent panels
`together.
`0.025
`Alternatively, rows of panels may be arranged in a
`Staggered arrangement for Structural Support, as is pictured
`in FIG. 6, with each panel abutting two adjacent panels at
`that panel's Second edge 7 and abutting another two adjacent
`panels at the opposite edge 15, extending to the top and
`bottom of the roof. Thus, the second tab 5 of each panel
`would partially overlap two adjacent panels instead of one.
`0026. One of skill in the art will recognize that roofing
`panels are preferably assembled onto a roofing deck and
`may be attached to the roofing deck using any number of
`methods known in the art. If nails are used on the roofing
`panels, they may be positioned on the edges So that the tabs
`may overlap the nail heads. Alternatively, if the weather
`resistant Surface layer 3 of each panel is not bonded to the
`panel body 2 along its edges, then the weather resistant
`surface layer 3 may be lifted up so that nails may be driven
`through the panel body without penetrating the weather
`resistant Surface layer 3.
`0.027
`Additionally, the first and second tabs 4, 5 are
`preferably bonded to the Surface layerS 3 on adjacent panels
`using an appropriate adhesive running down the entire
`length of each tab So that consecutive Surface layerS 3 are
`effectively sealed. Such an adhesive may be applied by hand
`after the panels are attached in position or the underSurface
`of the tabs may be provided with an appropriate adhesive
`during manufacture. In this way, nails may be unnecessary
`to connect the Surface layers 3, and leakage through nail
`holes can be reduced or avoided. However, mechanical
`fastening means Such as-Staples may be used if desired to
`attach and retain tabs 4, 5 in overlapping positions. Alter
`natively, other attaching means known in the art may also be
`used to attach the tabs to adjacent Surface layers. Panels may
`also be prefabricated with Surface layerS having no coating
`along one or more of their edges for bonding purposes or
`with Surface layerS having a different material or consistency
`along one or more of the edges. Furthermore, the tabs could
`provide a Sealing redundancy by the Steps of first attaching
`the tabs to adjacent panels, and then overlaying the tabs with
`an additional Sealing material Such as an appropriate tape.
`The roofing panel of this invention may also comprise any
`number of tabs, connected or unconnected, including only a
`single tab as is illustrated in FIG. 3. Additional sealing may
`be used, if desired, by methods known in the art.
