Definitions

  • This invention relates generally to the field of roofing materials, and in particular to a new and improved roofing underlayment.
  • roofing materials are applied in a manner so that they are "square" with the ridge of the roof, and so that they are arranged in a generally parallel or “straight" configuration.
  • alignment of the shingles in equally spaced rows that are generally horizontal and parallel to the ridge of the roof ensures an aesthetically pleasing appearance and allows the shingles to function in the manner in which they were designed; namely, to shed water and prevent leakage.
  • Misalignment of shingles creates both an unattractive finished product and presents the potential for water to penetrate through the roof and into the building.
  • the exterior roofing material is comprised of asphalt shingles, tiles, galvanised or other metallic sheeting, wooden shakes, slate or any one of a wide variety of other commonly used roofing materials, there exists a need to apply the roofing material in an aligned and "square" fashion.
  • roofing materials When applied to a roof substrate, installation personnel typically resort to one of a variety of common construction methods that enable subsequent rows of roofing materials to be aligned with previously applied rows. For example, carpenters and roofers will often mark parallel lines across the roofing substrate (which in wooden construction is typically plywood, exterior wooden sheeting, or roofing boards) through the use of a pencil, marker or chalk line. In other instances the installer may use a tape measure to physically measure the distance between respective rows of roofing materials as each row is laid down. While both of these methods may be effective, they are also labour intensive and introduce the potential for error as there is a constant requirement for individuals to take measurements and mark the position for subsequent rows of roofing materials. Failure to measure or mark accurately can result in an alignment problem.
  • roofing materials can be further complicated by the fact that a liner or underlayment is commonly applied to the roof substrate prior to the application of shingles, shakes, tiles or other roofing materials.
  • underlayments may be comprised of a wide variety of products including roofing paper (generally comprised of a petroleum coated cellulose product and often referred to as tar paper), roofing felt (comprised generally of asphalt saturated organic felt which may be coated or uncoated), rubber or rubberized membranes, and an equally wide variety of synthetic underlayments (both woven and extruded). Regardless of the particular form of underlayment that is utilized, its function is essentially the same; to provide a secondary barrier to water and moisture beneath the shingles, tiles or other roofing materials and next to the roof substrate.
  • the underlayment is applied to the roof substrate in a series of horizontal rows and is secured to the roof through the use of nails, staples or an adhesive. Once applied, the underlayment obscures the roof substrate from view making it even more difficult for a roofer to properly align the overlying roofing materials.
  • the invention therefore provides a product and a method that allows for the installation of shingles and other roofing materials in an aligned pattern that is "square" with the roof structure, that is cost effective, and that minimizes the potential for human error and the misalignment of roofing materials.
  • a roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials, the underlayment comprising a sheeting material having an upper surface and a lower surface, said underlayment containing a grid that is visually identifiable from above said underlayment when said underlayment is received over said roof substrate with said lower surface of said underlayment adjacent to said roof substrate, said grid assisting in the alignment of said underlayment with said roofing substrate during application of said underlayment to said substrate and further assisting in the alignment of roofing materials applied over said underlayment.
  • the invention provides a roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials, the underlayment comprising a sheeting material having an upper surface and a lower surface, said underlayment containing a grid that is visually identifiable from above said underlayment when said underlayment is received over said roof substrate with said lower surface of said underlayment adjacent to said roof substrate, said grid comprised of a series of equally spaced apart lines that are parallel to the longitudinal axis of said underlayment and a series of equally spaced apart lines that are perpendicular to the longitudinal axis of said underlayment, said grid assisting in the alignment of said underlayment with said roofing substrate during application of said underlayment to said substrate and further assisting in the alignment of roofing materials applied over said underlayment.
  • the invention provides a roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials, the underlayment comprising a sheeting material having an upper surface and a lower surface, said underlayment containing a grid that is visually identifiable from above said underlayment when said underlayment is received over said roof substrate with said lower surface of said underlayment adjacent to said roof substrate, said grid comprised of a series of spaced apart and parallel lines extending over at least a portion of said upper surface of said underlayment, said grid assisting in the alignment of said underlayment with said roofing substrate during application of said underlayment to said substrate and further assisting in the alignment of roofing materials applied over said underlayment.
  • the invention also provides a roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials, the underlayment comprising a sheeting material having an upper surface and a lower surface, said underlayment containing a grid that is visually identifiable when said underlayment is received over said roofing substrate with said lower surface of said underlayment adjacent to said substrate, said grid comprised of a series of spaced apart longitudinal lines that are parallel to the longitudinal axis of said underlayment and a series of spaced apart perpendicular lines that are perpendicular to the longitudinal axis of said underlayment, said longitudinal and said perpendicular lines coloured to distinguish said lines from said sheeting material.
  • the invention concerns a roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials, the underlayment comprising a sheeting material having an upper surface and a lower surface, said underlayment containing a grid that is visually identifiable when said underlayment is received over said roofing substrate with said lower surface of said underlayment adjacent to said substrate, said grid comprised of a series of spaced apart longitudinal lines that are parallel to the longitudinal axis of said underlayment and a series of spaced apart perpendicular lines that are perpendicular to the longitudinal axis of said underlayment, said longitudinal lines being of at least a first colour contrasting to the colour of said underlayment, said perpendicular lines being of at least a second colour contrasting to the colour of said underlayment.
  • roofing materials 4 are applied to form the finished roof.
  • substrate 1 would be comprised of plywood, exterior sheeting, or a series of wooden boards.
  • roofing materials 4 may be comprised of asphalt shingles as shown in Figure 1, the roofing material may equally be any one of a wide variety of exterior roofing products, including clay or cement tiles, wooden shakes, metal roofing materials, slate, etc.
  • the scope of the present invention is not limited to any particular roofing material.
  • underlayment 3 will be comprised of a relatively thin and flexible material formed into rolls (see Figures 3, 4 and 5) that may be cut to length as necessary. While underlayment 3 may be manufactured to practically any desired dimension, for handling and transportation purposes rolls of a width of between 30 and 80 inches are most desirable. Where rolls of this size range are utilized a series of horizontally oriented rows of underlayment will be applied to the roof in order to fully cover substrate 1. Preferably the rows of underlayment material are applied beginning along the lower edge of the roof working toward the top such that each subsequent row that is higher up on the roof overlaps the adjacent lower row to allow any moisture that may come into contact with the underlayment to be shed as it flows downwardly along the pitch of the roof.
  • substantially larger rolls of material could be manufactured such that a single sheet of underlayment is capable of covering the entire exterior surface of substrate 1.
  • the substrate could be formed into a rigid or semi-rigid sheeting material that is applied to the roof in a manner similar to the application of the substrate material.
  • the composition and structure of underlayment 3 may vary substantially depending upon the particular application in question.
  • the underlayment may range from a common tar paper or roofing felt structure, to a plastic or rubberized or PVC ice and water shield, to a single ply thermoplastic (for example polyolefin) membrane, to a high strength woven product comprised of a series of woven tapes, yams and/or filaments (identified generally as 12 in Figure 7).
  • the underlayment may also be coated on one or both sides to enhance abrasion resistence, to increase strength and water resistance, and/or to present a slip resistant surface.
  • the preferred embodiment of the invention is not limited to one form of underlayment or a particular method of manufacture.
  • underlayment 3 is comprised of a sheeting or sheet-like material having an upper surface 5 and a lower surface 6 that is received over roof substrate 1.
  • underlayment 3 is secured to substrate 1 through the use of nails, staples or an adhesive.
  • at least the upper surface 6 of underlayment 3 contains a visually identifiable grid 7. Grid 7 assists in both the alignment of the underlayment with the roof substrate (and with subsequent rows of underlayment) during application of the underlayment to the roof, and also assists in the subsequent alignment of roofing materials that are applied over the underlayment.
  • grid 7 may be applied or adhered to underlayment 3, including printing or embossing the grid upon upper surface 6 of the underlayment.
  • grid 7 is embossed on the surface of underlayment 3 the effect may be the formation of small linear indentations 11 across the surface of the underlayment (see Figure 8).
  • Grid 7 may also be printed, embossed or otherwise applied to both upper surface 5 and lower surface 6 allowing either of the outer surfaces of the underlayment to be placed adjacent to roof substrate 1.
  • the embossed surface will also tend to exhibit anti-skid characteristics further enhancing the characteristics of the product.
  • grid 7 may be comprised of a series of yams, tapes and/or filaments 10 that are woven into the underlayment where the underlayment is a woven scrim (See generally Figure 7).
  • the yarns, tapes and/or filaments 10 are preferably coloured a contrasting colour to the scrim and may be superimposed or adjacent to the yams, tapes and/or filaments 12 of the scrim.
  • yams, tapes and/or filaments 10 may be otherwise adhered to either the upper and/or the lower surface of the underlayment (for example see Figure 9) through the use of an adhesive, or during a coating process where the underlayment is a coated product.
  • grid 7 is comprised of a series of equally spaced apart lines 8 that are parallel to the longitudinal axis of the sheeting material from which the underlayment is made (see Figure 3).
  • grid 7 may be comprised of a series of equally spaced apart lines 9 that are perpendicular to the longitudinal axis of the sheeting material (see Figure 4).
  • grid 7 may be comprised of both a series of equally spaced apart lines 8 that are parallel to the longitudinal axis of the sheeting material, and a series of equally spaced apart lines 9 that are perpendicular to the longitudinal axis of the sheeting material (see Figures 5A, 5B and 5C).
  • the lines that comprise grid 7 must be visually identifiable, and to that extent they are preferably of a colour other than that of the sheeting material from which the underlayment is constructed (or other than the coating material where the underlayment is a coated product).
  • grid 7 may be black, green, red or some other contrasting colour making the lines of the grid clearly identifiable upon the surface of the product.
  • the lines comprising grid 7 may in some fashion alternate in colour between a first colour and a second colour to present a further visual identification and distinction between adjacent or groups of lines.
  • grid 7 comprises a one inch spacing between lines that are parallel to the longitudinal axis of the underlayment with the lines alternating in colour between green and black.
  • grid 7 may be comprised of lines that are parallel to the longitudinal axis of the underlayment and that are spaced apart by one inch increments, and lines that are perpendicular to the longitudinal axis of the underlayment and also spaced apart in one inch increments.
  • the longitudinally oriented lines may be black with the perpendicular lines green, presenting a visual distinction between the rows of lines that will effectively be oriented vertically and horizontally when underlayment 3 is placed in a generally horizontal configuration across roof substrate 1.
  • the alternating colours of the lines forming in grid 7 helps to present a visual distinction between adjacent lines and assists in the alignment of underlayment 3 and roofing materials 4.
  • grid 7 is comprised of lines that are parallel to the longitudinal axis of the underlayment with adjacent parallel lines alternating in colour.
  • the grid is further comprised of lines that are perpendicular to the longitudinal axis of the underlayment with adjacent perpendicular lines alternating in colour.
  • grid 7 is comprised of a series of lines parallel to the longitudinal axis of the underlayment and equally spaced apart in one inch increments.
  • the longitudinally oriented lines alternate in colour in six inch blocks creating groups of lines of like colours that alternate every six inches.
  • the grid further comprises a series of lines perpendicular to the longitudinal axis of the underlayment and also spaced apart in one inch increments. As in the case of the longitudinally oriented lines, the perpendicular lines alternate in colour in six inch blocks.
  • grid 7 may be comprised of lines that are solid, broken or patterned (for example small dots, squares, etc.).
  • a roofer is provided with a means by which the underlayment itself can be easily aligned with the roof substrate, and in particular the ridge of the roof.
  • the roofing installer is able to quickly and easily align adjacent rows with one another so that they maintain their horizontal attitude and to ensure that each subsequent row positioned higher up on the roof is both parallel to the lower adjacent row and over laps the lower row by sufficient degree.
  • the grid pattern that is visually identifiable thereon presents the roofer with an ability to quickly and accurately align shingles or other roofing materials with both one another and with the roof.
  • An example showing how underlayment 3 may be used to assist in the alignment of shingles is shown in Figure 6.
  • underlayment 3 will remove the necessity for roofers to use chalk lines, straight edges, measuring tapes and other implements to ensure alignment of roofing materials as they are applied.
  • the invention also removes the need for measuring, and the associated potential for error in either failing to measure properly or failing to mark a measurement properly upon the roof.
  • the roofer need only align the shingles or the roofing materials with the grid pattern upon underlayment 3 to ensure that the roofing materials are installed in a horizontal and parallel configuration with adequate overlap. Where the underlayment exhibits anti-skid characteristics its application over a roof substrate will also present an inherently safer work surface for roofing installers.
