Are GAF Timberline shingles rated Class 3?
Ratings across the Timberline family
- Timberline HDZ: Class 3 on packages bearing the statement.
- Timberline UHDZ with UltraMat: Class 4 on packages bearing the UltraMat logo and Class 4 statement.
- Timberline AS II: Class 4.
- Other or older Timberline products: check the wrapper or spec sheet, since not every product or production run carried an impact rating.
How to confirm yours
Look at a leftover bundle in the garage or attic for the UL 2218 statement, or ask your installer for the product documentation and invoice. If your roof was installed some years ago, do not assume it carries the rating; check the records from that job.
What Class 3 does for you
It means better resistance to the moderate hail that hits Georgia most springs than an unrated shingle. It is a lab comparison with steel balls, not a promise about a particular storm, and very large or wind-driven hail can still cause damage.
Insurance
Many insurer discount programs are written around Class 4, not Class 3. Ask your agent before counting on a credit.
Not a hail warranty
GAF states that it makes no warranty about impact performance against hail and that hail damage is not covered under its limited warranty. Storm damage is an insurance matter. For more, see impact-resistant shingles in Georgia and Georgia hail season.
