One way to determine the age of a shingle is to look for identifying markings or codes on the shingle. Most shingles are stamped with a date code that indicates when they were manufactured. The date code is typically a series of numbers and letters that can be deciphered using a code chart. Alternatively, you can try to determine the age of a shingle by looking at its overall condition. As shingles age, they may become brittle, fade in color, or develop other signs of wear and tear. By comparing the condition of the shingle to known examples of shingles of different ages, you may be able to approximate its age. Keep in mind that these methods are not always reliable, and the only way to know for certain the age of a shingle is to check its date code or consult the manufacturer.
