- 1. Field of the Invention
- This invention relates to the prevention of leakage at the corner intersection of roof penetrations—such as at those locations where chimneys exit through the roof and where dormers meet the slanted plane of the roof. More particularly, the invention represents an improvement over the corner flashing shown in U.S. Pat. No. 5,077,943 to McGady, issued Jan. 7, 1992.
- 2. Description of the Related Art
- As will be appreciated, at these intersections, a roofing contractor conventionally trims a piece of flashing into a corner so that a waterproof envelope is provided by the shingles of the laid roof. As will also be appreciated, to do it properly in the field takes time and skill—neither of which the typical installer possesses, usually being only paid piece-work, “by the square”. This oftentimes results in a flashing installation which is sloppily done. In fact, experience has shown that almost 90% of those roof leaks that develop occur not at the body of the shingles, but at these corners, when the flashing fails.
- McGady recognizes this problem in his above identified patent, and attempts to deal with it by having a corner flashing member adapted for adjustment in the field. This is done utilizing a “tuck”, said to cause the upstanding sides of the flashing member to tightly embrace the chimney or dormer above the roof line. Besides continuing to require a high degree of skill to overlap the sides in forming the tuck at a vertical corner, however, the suggestion there put forth provides only minimum protection at the point where the vertical planes and horizontal plane of the flashing intersect at the base. Analysis has shown that this is due to its triangular flap which contains no overlap whatsoever at the intersection. Since the McGady flashing unit is intended for fitting all roof pitches, extensive modification must be performed in the field—which the everyday worker normally does not possess. Even so, the intersecting point of the two vertical sections and the horizontal section continues as a “weak point” for possible water infiltration caused by the resulting seam at the juncture.
- As will become clear from the following description, the flashing of the present invention consists of one-piece molded plastic corner which precisely fits the outside corner of chimneys, dormers and roof offsets on pitched roofs ranging from 3/12 to 12/12 pitches. Because each flashing is molded to fit each particular roof pitch, an easy and water-tight installation is achieved, without any field modification or cutting—merely by selecting the appropriate one to match with the roof pitch. Including a horizontal plane, a front or rear vertical plane, and a side vertical plane, the angles between the planes change from roof-to-roof, as the roof pitch changes. With each plane being a minimum 5″×7″ in size, the overlapping of laid down shingles allows for an installation without gaps or seams which sits tightly on the roof. Requiring no field modification, the one-piece molded plastic corner flashing will be appreciated to meet all specifications of the National Roofing Contractors Association (NRCA).
- These and other features of the present invention will be more clearly understood from a consideration of the following description, taken in connection with the accompanying drawings, in which:
-
FIGS. 1-4 are perspective views helpful in an understanding of the McGady flashing installation, and how its “tucking” and “seaming” construction invites water leakage; and -
FIGS. 5 a-5 e are views helpful in an understanding of a one-piece molded plastic corner according to the present invention employed as a lower flashing for an installation; -
FIGS. 6 a-6 e are views helpful in an understanding of a one-piece molded plastic corner according to the invention employed as an upper flashing for an installation; and -
FIGS. 7 and 8 are perspective views from opposite positions of a chimney set-up helpful in understanding the installation of the one-piece molded plastic corner. - In the prior art drawings of
FIGS. 1-4 , the McGady corner flashing 10 includes abase 11 with an integralupstanding corner 12 having a pair ofsides corner 15, theupstanding corner 12 is substantially in right angle relationship with thebase 11. - As U.S. Pat. No. 5,077,943 describes, the
base 11 is rectangular with parallel top and bottom edges, and parallel opposite sides intersecting at corners. The upper left-hand corner of thebase 11 is notched out to provide a rectangular recess with edges which intersect at a corner spaced from the top, bottom and side edges of the base. Theupstanding corner 12 forms a continuous junction with the base member that is coextensive with the recess, and thebase 11 is “L”-shaped with leg portions radiating fromsides upstanding corner 12. Composed of a bendable plastic material, the flashing 10 is selected of a thickness so as to be sufficiently flexible in conforming with the corner to be sealed, regardless of the inclination of thebase 11 when placed on a roof deck. - As shown in
FIG. 3 , the flashing 10 is applied to the lower corners of achimney 16 at aninclined roof deck 17, with thebase 11 of the flashing 10 mounted on the deck to extend laterally and below the chimney. Theupstanding sides roof shingles 20 to be applied in conventional overlapping relation to cover the deck and extend up the roof line to intersect with the chimney. - As respects the matter of “tucking”, McGady continues to incline the roof deck mounted
base 11 of the right-hand bottom corner flashing 10, as well as theside 13 of theupstanding corner 12 in allowing theside 14 to tightly abut the flashing 18. To draw theside 13 into tight abutment with the flashing 19, thecorner 15 between thesides side 14 in forming this tuck, 21. Such tuck overlaps theside 14 and is secured in position by a fastener, such as anail 22 driven through the top end of the tuck into the chimney. The left-hand bottom corner flashing, in similar manner, has theside 14 of the corner tilted away from the flashing 19, so as to form the tuck and drawing it against the flashing 19. - As McGady describes, the
tuck 21 overlaps theside 14 to be nailed to the side wall of thechimney 16. Alternately, the tuck is said to be overlappable of theside wall 13 so as to be securable to the front or bottom end wall of thechimney 16. With this one flashing unit said to be fittable to all roof pitches, an actual installation requires field modification to fit the particular roof pitch encountered. Such modification must be performed by the installer—who, as was previously mentioned, is more trained in laying shingles down in courses, then he/she is in bending and trimming planes of flashing. - More importantly, however, McGady's corner flashing in this respect offers minimal protection at the point where the vertical planes and horizontal plane of the flashing intersect at the base, and due to the triangular flap that contains no overlap at this intersection. In essence, a “hole” 100 is created at the intersection of the
base 11 and thesides fold 101 between thetuck 21 and theside 14. Such fold catches rain, sleet and snow, for example, and directs it down along the inside of the tuck through thehole 100, its weakest point. Because there is no overlap, not only is there a leakage, but a failure to meet National Roofing Contractors Association's installation specifications. (The same will also be understood as to any rain, sleet or snow entering from behind the fold.) These problems are eliminated, however, in accordance with the teachings of the present invention. In particular,FIG. 5 a is a perspective view of a one-piece molded plastic corner according to the invention, withFIGS. 5 b-5 e respectively illustrating views taken in the direction of the arrows A, B, C and D inFIG. 5 a. As shown, the corner is molded of three planes—ahorizontal roof plane 30, a frontvertical plane 31 and a side vertical plane 32 (which, if rotated counter-clockwise 90° places thevertical wall 31 as a side wall and thevertical wall 32 as a front wall, seeFIGS. 7 and 8 ). Molded of 1/16″ to ⅛″ thick plastic, and with each plane being a minimum of 5″×7″ in size, an easy and water-tight installation can be achieved by installing the flashing of a size to fit each particular roof pitch. Thus, for a one-piece molded plastic corner with a 12″×12″ base 30 and vertical planes 7″ wide and 6″ high, a corner flashing for a 5:12 pitch roof would have the following angles:Angle 4067° Angle 41113° Angle 4223° Angle 4390°. - For a 6:12 pitch roof, on the other hand, these angles would change thusly:
Angle 4063° Angle 41117° Angle 4227° Angle 4390°. - To construct this one-piece molded plastic corner for 7:12, 8:12, 9:12, 10:12, 11:12 and 12:12 pitch roofs, all that would be required would be to continually decrease the
angle 40 and increase theangles angle 40 and theangles arrows 105 inFIG. 5 a signify a “roof pitch down” position, for this lowercorner flashing unit 72 of the invention. - As will be readily appreciated by those skilled in the art, comparable selections can be made for custom fitting the corner flashings as upper flashings (
FIGS. 6 a-6 e), just as the corner flashing ofFIGS. 5 a-5 e are usable as lower flashings. With abase 50, a rearvertical plane 51 and a sidevertical plane 52, the same utilization would follow for the upper flashing unit rotated clockwise 90° as inFIGS. 7 and 8 . Thearrows 106 inFIG. 6 a signify the “roof pitch down” position for this uppercorner flashing unit 73. - When so selected, an appearance of the
roof 70, achimney 71, the two lowercorner flashing units 72 and the two uppercorner flashing units 73 is as shown in the perspective views ofFIGS. 7 and 8 . With the same 12″×12″ dimension for the horizontal roof planes, and with the same 7″ wide and 6″ high dimensions for the vertical planes, the corner flashing of the invention can be custom fitted to any roof pitch just by selecting theproper angulations - While there have been described what are considered to be preferred embodiments of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. Thus, although 4° angular increments are specified in fitting the corner flashing unit of the invention to different pitched roofs, it will be understood that the exact incremental angles are selected to substantially match exactly to the different pitches of the roof that is installed. In particular, in accordance with the invention, a water-tight flashing follows so long as angles
40+42=43;
42+43=41;
and
angle 43 equals 90°. As will be apparent,angle 42 is that angle of the horizontal plane along the downwardly pitched roof, whileangles angle 43 will be seen to be that between the two vertical planes. For at least such reason, therefore, resort should be had to the claims appended hereto for a true understanding of the invention.
