PABCO HO-25 and PABCO HZ-25 Roof Shingle, Product Identification Program
This shingle was principally sold under the name HO-25. It has also been referred to as Horizon and HZ-25.
It was sold by PABCO Roofing Products from September 16, 1984 through 1997.
It was primarily sold in Washington, Oregon and California. Small quantities were sold in Idaho, Nevada Hawaii, Utah and Montana. Very limited quantities were sold in Minnesota from approximately 1995 to 1997, and in Arizona.
Similar products are known to have been sold in some of these regions by other companies prior to, during and after this time period. This class action only applies to the PABCO HO-25 and PABCO HZ-25 shingles manufactured by PABCO Roofing Products.
The following pages provide product diagrams and information for identifying whether or not shingles are PABCO HO-25 and PABCO HZ-25 shingles.
The following diagrams illustrate several feature differences which distinguish PABCO HO-25 and PABCO HZ-25 shingles from either 3 tab shingles or laminated shingles.
PABCO HO-25 and PABCO HZ-25 Shingles
3 Tab Shingle
Asphalt shingles are covered by colored granules. The application of specific colors in specific locations is key to the overall appearance of the roof. The location of specific colors and contrasts in colors is an important part of determining whether or not a given shingle roof is covered by PABCO HO-25 or PABCO HZ-25 shingles.
When the shingles are applied on a roof, they have only their lower portion visible. For PABCO HO-25 and PABCO HZ-25 shingles, that lower portion was 5 5/8" in height, the distance from the leading edge to the top of the cut out slots. The upper portion is not visible because it is covered by the bottom portion of the next layer of shingles.
There are differences between PABCO HO-25 or PABCO HZ-25 shingles and 3 tab shingles that aid in determining whether or not your shingles are PABCO HO-25 or PABCO HZ-25 shingles.
Additionally, PABCO HO-25 and PABCO HZ-25 shingles were always the same size, 13 1/4" by 39 3/8". The exposed height was always 5 5/8". The width of each tab [distance between cut out slots] was 12 7/8". 3 tab shingles are typically the same size, but some products are a different size, such as 12" by 36", with 11 3/4" tabs and a 5" exposed height.
These are the primary differences between PABCO HO-25 or PABCO HZ-25 shingles and 3 tab shingles. As previously stated, similar products are known to have been sold by other companies prior to, during and after the same time period as PABCO HO-25 and PABCO HZ-25 shingles were sold. The differences noted above may or may not apply to those other brands. This class action only applies to PABCO HO-25 and PABCO HZ-25 shingles.
PABCO HO-25 and PABCO HZ-25 shingles were designed to look like laminated shingles. As applied, both products only show the area from the shadow line down. The "Overlay Pads" are a contrasting color to the area between the pads. This causes them to stand out and generates an appearance similar to the teeth against the backing shim of a laminated shingle [see diagram below].
There are differences between PABCO HO-25 and PABCO HZ-25 shingles and laminated shingles that aid in determining whether or not your shingles are PABCO HO-25 or PABCO HZ-25 shingles. The overlay pad on a PABCO HO-25 or PABCO HZ-25 shingle cannot be peeled up from the base shingle. The shim piece on a laminated shingle is adhered to the back of the other piece [with the teeth], positioned behind the teeth. With a laminated shingle, it is usually possible to peel up the tooth from the shim when the shingle is hot.
If you have determined that your shingles have been made like PABCO HO-25 or PABCO HZ-25 shingles, the next step is to determine if they were manufactured by PABCO, or some other company. This class action litigation only applies to the PABCO HO-25 and PABCO HZ-25 shingles.
These differences should help distinguish between the PABCO HO-25 and PABCO HZ-25 shingles and other products. However, PABCO does not have all possible information on the similar products made by other manufacturers. There are additional considerations possible that are too detailed to cover in this document. Products that meet all of the above details may still be determined to have been made a different manufacturer than PABCO Roofing Products, based upon additional examination and information.
