The most common discontinued shingles I have encountered are:
Owens Corning - Prominence
- This is a faux-laminate shingle. Meaning that the shingle gives the appearance of a dimensional grade shingle, but is truly a 3-tab shingle.
- This is discontinued for "unique wear characteristics"
- Note: shingle manufacturers hate it when we call their shingles "defective" to the insureds.
- I often refer to these shingles as "hail damaged out of the box".
- The faux-laminate strip wears off almost immediately. Giving the appearance of hail damage.
- DO NOT BUY THESE SHINGLES FOR HAIL DAMAGE ON THE FAUX-LAMINATE STRIP! If there really is hail damage to this shingle, look for it elsewhere on the shingle. Key-ways are extremely helpful!

Certainteed - Hearthstead
- Easily identified by unique key-ways.
- Key-ways start out wide and then narrow.
- Is a 4-tab shingle.
- Have a strong shadow line.
Certainteed - Classic Horizon & New Horizon
- This is Certainteed's version of the OC Prominence shingle.
- It also features a faux-laminate strip (doesn't that sound prestigious?)
- There are two different versions in the Horizon series: Classic Horizon and New Horizon.
- They are both discontinued, the only difference is that the Classic Horizons are a 3-tab shingle where the New Horizons are a 1-tab shingle.

T-Lock Shingles
- These shingles aren't necessarily "commonly overlooked" but they are discontinued nonetheless!
- There is nothing left in the market that is considered LKQ (Like Kind and Quality) or similar construction.
- These shingles are heavier in weight than normal 3-tab shingles. Xactimate used to have a code for this type of shingle. It was RFG 280 for heavyweight shingles. However, due to recent price list changes, Xactimate no longer has this code available for use. The closest thing in Xactimate (when considering the t-lock shingle's weight) is RFG 300. Please remember to read the line item description and use some of that language when entering your file notes to justify use of the RFG 300 line item for this shingle.
If you find any of the shingles referenced on this page, I like to play a game called "find the missing shingle". because if you are missing just 1 shingle on this type of roof you can toast the whole thing for the shingle not being available due the product being discontinued with no like kind quality or product of similar construction available. (consult with your manager) Likewise can be said for actual hail damage found on these shingles.
