FLASHING ASSEMBLY HAVING A CAVITY WITH SEALING MASTIC THEREIN Filed Oct. 21. 1963 Firs. 3. 42' /46 INVENTOR. LA VERA/E 6. SM/ TH E) H/S ,4 77'0RA/EY5 HARE/$7 Mac/1, Ros-$51.4. 2 KER/v United States Patent 3,277,618 FLASHING ASSEMBLY HAVING A CAVITY WITH SEALING MASTIC THEREIN LaVerue G. Smith, 337 N. Douglas St., Los Angeles, Calif. Filed Oct. 21, 1963, Ser. No. 317,705 7 Claims. (CI. 52-58) My invention relates to roof flashings and, more particularly, to a roof flashing to be mounted on a concrete wall or the like for the purpose of shielding a given area thereof from water.
Prior roof flashing have employed a metal flashing sheet attached to the face of a wall and shaped to form with the wall a longitudinal recess which is packed with a plastic sealing material to keep water from flowing down the face of the wall into the space behind such flashing sheet. This general application has proved to be unsatisfactory in at least two important aspects. In many instances the effect of the sealing material located between the metal flashing sheet and the wall has been completely neutralized by permitting the sealing material to be constantly exposed to the atmosphere. Through continued exposure of the sealing material to the atmosphere it suffers from oxidation and dissipation of its oils resulting in drying out and shrinkage. Thus, cracks may form between the sealing material and the wall or between the sealing material and the flashing sheet permitting water to pass therethrough into the protected area. Further, prior flashing constructions have given little or no consideration to the importance of providing a removable shield which extends downwardly over the area desired to be protected a sufficent distance to preclude Wind turbulence from driving water up under the flashing and into the protected area, which shield may be removed in order to treat or repair the underlying roof.
Accordingly, it is an object of this invention to provide a flashing member which will eliminate water leakage between the wall and the sealing material and between the sealing material and the flashing sheet itself. Another object of this invention is to provide a flashing member which includes a downwardly extending flange for shielding a given area of the wall from water which normally would be driven by the Wind up into the protected area.
A further object of this invention is to provide a flashing member including a longitudinal cavity opening toward a wall on which the flashing member is mounted and having a mastic sealing material filling the cavity, which mastic sealing material is completely protected from the atmosphere by the flashing member.
Still another object of this invention is to provide a flashing member having a removable shield which extends downwardly over the area desired to be protected a suflicient distance to preclude water from being driven upwardly by wind or the like into the protected area.
A further object of this invention is to provide a flashing member having an upper strip including a pair of longitudinal V-shaped grooves opening toward a wall on which the flashing member is mounted, a sealing material located within these grooves and between the upper strip and the wall, and a means for securing the flashing member to the wall located intermediate the longitudinal V- shaped grooves.
Still another object of thi invention is to provide a flashing member mounted on a wall above the edge of a roof covering having an upper strip including a pair of longitudinally V-shaped grooves opening toward the wall, a sealing material located within the V-shaped grooves, a means for securing the flashing member to the wall located intermediate the V-shaped grooves, and a lower strip secured to the upper strip adjacent the lower edge thereof and extending below such lower edge and spaced forwardly of the wall.
3,277,618 Patented Oct. 11, 1966 ice A still further object of this invention is to provide a flashing member for a wall having an upper strip including an upper edge engaging the wall, an intermediate portion secured to the wall, and a lower edge spaced outwardly from the wall; a securing means for fastening the intermediate portion of the upper strip to the wall; a sealing material located between the upper edge and the intermediate portion; and a lower strip secured to the upper strip adjacent the lower edge thereof, extending downwardly therefrom and spaced from the wall.
Another object of this invention is to provide a flashing member for a wall including an upper strip having an upper edge engaging the wall, an intermediate portion secured to the wall, and a lower portion having an edge spaced outwardly from the wall and providing a plurality of rearwardly extending bosses; a securing means fastening the intermediate portion of the upper strip to the wall; a sealing material located between the upper strip and the wall and between the upper edge and the intermediate portion; and a lower strip including a raised intermediate portion extending forwardly thereof and adapted to engage each of the rearwardly extending bosses on the upper strip, means for securing the lower strip to the upper strip at the points of engagement between the rearwardly extending bosses and the raised portion, an upper overhanging flange extending forwardly from the lower strip and terminating adjacent the upper strip, and a lower flange extending forwardly from the lower strip and positioned below the lower edge of the upper strip and spaced outwardly from the wall.
A further object of this invention is to provide a flashing member mounted on a wall above the edge of a roof covering including an upper strip movable from a first position to a second position, including a first portion defining a longitudinal V-shaped groove opening toward the wall and having an upper edge engaging the wall, the volume of the V-shaped groove decreasing as the upper strip is moved from the first to the second position, a second portion positioned below the first portion and defining a V-shaped groove opening toward the wall, the volume of the V-shaped groove decreasing as the upper strip is moved from the first to the second position, an intermediate portion located between the grooves defining a longitudinal outwardly facing channel, which intermediate portion is movable from a position spaced outwardly from the wall when the upper strip is in the first position to a position adjacent to the wall when the upper strip is moved to the second position, and a lower portion having an edge spaced downwardly from the first and second portions and spaced forwardly of the wall; means for moving the upper strip from the first position to the second position and securing the intermediate portion to the wall; a sealing material located within the V-shaped grooves between the upper strip and the wall; and a lower strip secured to the upper strip adjacent the lower edge thereof extending below the lower edge and spaced outwardly of the wall.
Still another object of this invention is to provide a flashing member mounted on a wall including a nail for securing the flashing member to the wall, the nail having a head thereon and a longitudinal bar adapted to be carried on the nail and engageable with the head thereof for engaging the bottom of the outwardly facing channel when the nail is urged into a securing position causing the upper strip to move from the first to the second position.
A still further object of this invention is to provide an improved method of flashing the edge of a roof covering adjacent an upstanding wall.
A preferred embodiment of the present invention is illustrated in the accompanying drawing in which:
FIG. 1 is a fragmentary perspective view of the invention shown as mounted on a wall;
FIG. 2 is a cross-sectional view taken along the lines 22 of FIG. 1;
FIG. 3 is a fragmentary cross-sectional view taken along the line 33 of FIG. 2;
FIG. 4 is a cross-sectional view of the invention shown in position to be mounted on a wall; and
FIG. 5 is an enlarged perspective view of a means for securing the flashing member to a wall.
Referring to FIGS. 1 and 2 of the drawing, the flashing member is shown as mounted on a concrete wall 11 for the purpose of shielding a given area thereof and the upper edge of a roof covering 12 from water. The flashing member 10 may be constructed of a noncorrosive metal such as aluminum or the like and includes an upper strip 14 having a first longitudinal V-shaped groove 16 opening toward the wall 11 and an upper edge 18 engaging the wall. A second and shallower longitudinal V-shaped groove 20 is positioned below the V-shaped groove 16 opening toward the wall 11 and terminating in a lower edge 18A engaging the wall. An intermediate portion 22 is located between the first and second V- shaped grooves 16 and 20, and defines a longitudinal outwardly facing channel 24. The flashing member 10 also provides an inverted L-shaped portion 25 which extends forwardly from the wall 11 and downwardly from the V- shaped grooves 16 and 20, terminating in a bottom edge 26. A plurality of rearwardly extending bosses 28 is located on the inverted L-shaped portion 25 and adjacent the bottom edge 26. Positioned axially-of each of the bosses 28 is a bolt receiving opening 30.
A concrete nail 32 having a head 34 will normally be used to secure the flashing member 10 to the wall 11 in conjunction with a longitudinal cylindrical bar 36, which is adapted to be positioned transversely on the nail 32 and adjacent the head 34. The bar 36 has an opening 38 therein through which the nail 32 passes, the diameter of the opening 38 being only slightly larger than the diameter of the nail 32 but less than the diameter of the head 34. Thus, the bar 36 is rotatable relative to the nail 32. Referring again to FIG. 2 of the drawing, the nail 32 is shown as passing through the upper strip 14 at the intermediate portion 22 and into the concrete wall 11. In this position, the longitudinal bar 36 engages the upper strip 14 within the channel 24.
A mastic sealing material 40 is positioned between the V- shaped grooves 16 and 20 in the upper strip 14 and the wall 11 and substantially fills each of the V-shaped grooves. It should be noted that since it is a primary object of this invention to provide a flashing member which completely encloses and protects the masticsealing material 40 from continued exposure to the atmosphere, the exposed end of the flashing member 10 (as shown in FIG. 1 of the drawing) will either be covered by an adjacent upper strip section 14 or by an end plate which is not shown.
A shielding flange or lower strip 42 is secured to the upper strip 14 adjacent the bottom edge 26. More particularly, the shielding flange 42 abuts the rearwardly directed bosses 28 and is secured to the upper strip 14 by bolts 44. The shielding flange 42 has an intermediate raised portion 46, an upper hook-shaped portion 48, and a lower forwardly flaring flange 50. The intermediate raised portion 46 engages the bosses 28 and receives the bolts 44. The raised portion 46 extends forwardly of the main body of the shielding flange 42 and the rearwardly extending bosses 28 serve to space the shielding flange 42 from the upper strip 14 in order to prevent water from creeping upwardly therebetween as the result of capillary action. With a space thus created between the raised portion 46 and the main body of the upper strip 14, water when driven by wind turbulence or the like can be forced upwardly therethrough. The hookshaped portion 48 on the shielding flange 42 is positioned above the raised portion 46 and extends forwardly from the shielding flange 42 terminating adjacent the upper strip 14. Any water that is driven up through the space between the raised portion 46 and the upper strip 14 is deflected downwardly by impinging upon the hook-shaped portion 48 which substantially covers this space some distance thereabove. Lastly, it should be noted that the forwardly flaring lower flange 50 is spaced downwardly from the bottom edge 26 of the upper strip 14 and is still positioned forwardly of the wall 11. This lower extension serves to further protect the upper edge of the roof covering 12 from being subjected to water which might be carried under the flashing member 10 by wind turbulence or the like.
In actual operation, the flashing member 10 is positioned adjacent the concrete wall 11 with the space between the upper strip 14 and the concrete wall 11 being filled with the mastic sealing material 40. In this position, the upper strip 14 conforms to the configuration of the phantom lines 52 shown in FIG. 2 and the View illustrated by FIG. 4. As clearly illustrated in FIG. 4, before the flashing is secured to the wall, at least a portion of the mastic 4!) lies to the right or outwardly of a line drawn between the edges 18 and 18a and the intermediate portion lies substantially on or to the left of such line. The phantom lines 52 show the upper strip 14 in its first and unsecured position. A concrete nail 32 is then driven through the upper strip 14 between the V- shaped grooves 16 and 20, and thus within the channel 24, and into the concrete wall 11. As the nail 32 is driven through the upper strip 14 and into the wall 11 the cylindrical bar 36 which is rotatable about the nail 32 provides inwardly directed pressure distribution longitudinally along the channel 24. And since the cylindrical bar 36 is rotatable about the nail 32 it specifically prevents any possible distortion of the upper strip 14 owing to misalignment of the nail 32 and the consequent engagement of the bar with the sloping walls of the V- shaped grooves 16 and 20.
As the nail 32 passes through the upper strip 14 and into the wall 11 the upper strip 14 is moved from the first unsecured position to a second secured position. The intermediate portion 22 is urged adjacent the wall and the V- shaped grooves 16 and 20 have their respective volumes decreased and are thus deformed and widened at their mouths adjacent the wall 11. In this connection, it is seen that as the intermediate portion 22 is urged toward the wall 11, the upper and lower edges 18 and 18A, respectively actually engage the wall and serve as sliding fulcrums about which the upper strip 14 is moved. The mastic 40 between the upper strip 14 and the wall 11 is compacted and spread beneath the upper edge 18, the intermediate portion 22 beneath the channel 24, and beneath the lower edge 18a, to insure a water-tight seal. Asshown in FIG. 2, the portions of the mastic 40 which are spread beneath the edges 18 and 18a form upper and lower longitudinal sealing beads, respectively, each of which extends along its respective edge outside of the cavities or grooves 16 and 20. In addition, it will be noted that the V-shaped groove 16 communicates with the V-shaped groove 20 between the intermediate portion 22 and the wall 11, thus defining a single mastic filled cavity beneath the flashing member 10. As discussed above, the shielding flange 42 is spaced rearwardly from the upper strip 14 adjacent the bottom edge 26, the distance between the flange 42 and the strip 14 being suflicient to prevent capillary action which would otherwise occur. The hook-shaped portion 48 serves as a shield to deflect'downwardly any water forced upwardly by Wind or the like through the space between the raised portion 46 of the shielding flange 42 and the bottom edge 26 of the upper strip 14.
Although an examplary embodiment of the invention has been disclosed herein for purposes of illustration, it will be understood that various minor changes, modifications, and substitutions may be incorporated in such embodiment without departing from the spirit of the invention as defined in the claims which follow.
