Abstract
A leak locating shingle comprises a body portion of the shingle with three tabs extending from a lower edge of the shingle. The upper corners of the body portion are trimmed at an angle. When two leak locating shingles are placed side by side, a water-trapping groove is created where the trimmed upper corners meet. If a leak occurs, water runs along the top edge of a shingle, until it encounters a water-trapping groove where the flow of the water trail is interrupted, due to the loss of a continuous path along the upper edge of the shingles. As water accumulates in the water-trapping groove, any water overflow occurs at the bottom of the water-trapping groove, causing the water to run over the top of the shingles. This limits the range of the water trail, and allows roof repair workers to more easily locate and repair the leak.

- 1. Field of the Invention
- The present invention relates to shingle tiles for roofing.
- 2. Description of the Related Art
- Roofers commonly utilize an asphalt shingle to protect a roof from weather and water damage. Among the various types of shingles available in the prior art are three-tab shingles, in which a long shingle body has three tabs extending from a lower edge of the shingle. In installation, these shingles are placed side by side along a lower edge of a roof. After this lower row is installed, another row is installed above the lower row, with the tabs of the shingles in the upper row overlapping the shingles in the lower row. This process is completed until the entire roof is covered.
- Problems in this design arise when a leak forms in a shingle. Water will leak through the leak source and run along the top edge of a row of shingles. This water trail may extend for a considerable length of the roof. When roof repair workers attempt to find the source, this water trail may extend for dozens of feet in either direction from the leak source. This often creates a need to remove shingles along the entire length of the water trail in an attempt to locate the leak source. This frequently results in a loss of an excessive amount of labor and materials spent removing and replacing serviceable shingles.
- A solution is needed to address one or more of these shortcomings in the prior art.
- A leak locating shingle comprises a body portion of the shingle with three tabs extending from a lower edge of the shingle. The upper corners of the body portion are trimmed at approximately a 22.5° angle.
- During installation, these shingles are placed side by side along a lower edge of a roof. After this lower row is installed, another row is installed above the lower row, with the tabs of the shingles in the upper row overlapping the shingles in the lower row. This process is completed until the entire roof is covered.
- When two leak locating shingles are placed side by side, a water-trapping groove is created where the trimmed upper corners meet. When a leak occurs, water runs along the top edge of a shingle. When the water trail encounters a water-trapping groove, the flow of the water trail is interrupted, due to the loss of a continuous path along the upper edge of the row of shingles.
- As water begins to accumulate in the water-trapping groove, any water overflow occurs at the bottom of the water-trapping groove, causing the water to run over the top of the shingles. This limits the range of the water trail, and allows roof repair workers to more easily locate and repair the leak.
- It should be understood that while this disclosure references three tab shingles, the system may likewise be used with dimensional shingles, architectural shingles, T-Lock shingles shingles, or other shingle type wherein the shingles are aligned with the top edge of the shingles in a row.

FIG. 1 depicts a three tab shingle of the prior art. -
FIG. 2 depicts an example of an installation pattern of three tab shingles of the prior art, with a water trail extending from a leak source. -
FIG. 3 depicts a leak locating shingle of the present invention. -
FIG. 4 depicts an example of an installation pattern of leak locating shingles, with a water trail extending from a leak source. -
FIG. 5 depicts the various layers of a cross-sectional view of a leak locating shingle. - Referring now to the drawings, a
leak locating shingle 30 is constructed in layers. Referring toFIG. 3 , each layer of aleak locating shingle 30 has abody portion 32, typically thirty-six inches (91.4 cm) in length and seven inches (17.8 cm) in height. Threetabs 34 extend from downward from the lower edge of thebody portion 32. Eachtab 34 is approximately twelve inches (30.5 cm) long and five inches (12.7 cm) in height, with asmall gap 36 between eachtab 34. The upper corners of thebody portion 32 are trimmed at approximately a 22.5° angle, at a depth of one to three inches (2.5-7.6 cm), and a width of one half to one and one half inches (1.3-3.8 cm). These angled edges form a water-trappinggroove 38 when theleak locating shingle 30 is placed adjacent to anotherleak locating shingle 30. - Referring now to
FIG. 5 , aleak locating shingle 30 typically comprises three or more layers. A first layer is typically a glassfiber reinforcing mat 50, comprising fiberglass bonded with resin. A second layer is typically anasphalt layer 52. A final layer typically comprises mineral orceramic granules 54. - Referring now to
FIG. 4 , leak locatingshingles 30 are installed in an overlapping pattern, as shown. Leak locatingshingles 30 are placed side by side along a lower edge of a roof to create a lower row. A next row ofleak locating shingles 30 is then placed slightly approximately 5.5 inches (14.0 cm) higher and offset laterally approximately six inches (15.2 cm) to stagger the rows such that thetabs 34 of higherleak locating shingles 30 slightly cover thegaps 36 between thetabs 34 of lowerleak locating shingles 30. This process is repeated until the roof is substantially covered byleak locating shingles 30. - This arrangement allows the trimmed corners of the
body portion 32 of theleak locating shingles 30 to form a water-trappinggrove 38. In the event that a leak occurs, water passes through aleak source 20 and travels under a row ofleak locating shingles 30. Awater trail 22 travels from theleak source 20 along the top edge of thebody portion 32 of theleak locating shingle 30. When thewater trail 22 encounters a water-trappinggroove 38, thewater trail 22 stops its lateral movement as it pools in the water-trappinggroove 38. - Once a sufficient amount of the
water trail 22 has pooled in the water-trappinggroove 38, the water begins to pass out of the water-trappinggroove 38 near the bottom of the water-trappinggroove 38 where the two adjacentleak locating shingles 30 meet. - Ideally, the
water trail 22 passes out of the water-trappinggroove 38 over theleak locating shingles 30 and runs off the surface of the roof. In rare cases, however, thewater trail 22 may pass out of the water-trappinggroove 38 under theleak locating shingle 30. In this case, thewater trail 22 travels along the top edge of thebody portion 32 of aleak locating shingle 30 beneath the firstleak locating shingle 30 until it encounters a water-trappinggroove 38, as described above. - In repairing a
leak source 20, workers find thewater trail 22 and attempt to follow thewater trail 22 to theleak source 20. Referring toroof shingles 10 of the prior art, as depicted inFIG. 1 , workers would have no way to locate the lateral location of theleak source 20, as depicted inFIG. 2 . Workers typically would have to remove allroof shingles 10 along the lateral row of theleak source 20 until theleak source 20 was found. - Referring now to
FIG. 4 , workers may be able to find the lateral location of theleak source 20 more easily with theleak locating shingle 30. The expulsion of thewater trail 22 over theleak locating shingle 30 at the water-trappinggroove 38 allows workers to quickly ascertain the lateral location of theleak source 20 within the length of one or twoleak locating shingles 30. Quickly finding the location of theleak source 20 allows the workers to save labor hours in locating theleak source 20 and refrain from removing a significant number ofleak locating shingles 30 when such removal would be unnecessary to repair theleak source 20. - It should be understood that while this disclosure references three tab shingles, the system may likewise be used with dimensional shingles, architectural shingles, or T-Lock shingles, or other shingle type wherein the shingles are aligned with the top edge of the shingles in a row.
