How do you identify roof shingles?
Short answer. Identify roof shingles in layers: first the material (asphalt, wood, slate, metal, synthetic or older cement-based), then the style (3-tab, architectural or designer), then the size and exposure, and finally the brand and product line from records or a leftover wrapper. When records are gone, a roofer can narrow it down from measurements and markings, and some insurance claims rely on lab analysis of a sample.
Step 1: material
- Asphalt: granule-covered and flexible, on the vast majority of Georgia homes.
- Wood shakes or shingles: split or sawn wood that grays with age.
- Slate: heavy natural stone, rigid and cool to the touch.
- Metal shingles or stone-coated steel: stamped panels, sometimes with a granule coating.
- Fiber cement or asbestos cement: rigid, flat and brittle, found on some houses built before about 1980. Do not cut or break them before testing.
Step 2: style
3-tab shingles show uniform slots and flat rectangles; architectural shingles show random tab widths and shadow lines; designer shingles imitate slate or large shakes with bold cuts.
Step 3: size
Measure the shingle length and the exposure. Metric shingles are about 39 3/8 inches long with a 5 5/8 inch exposure; older English-size shingles are about 36 inches long with a 5 inch exposure.
Step 4: brand and product
- Check closing papers, permits, the home inspection report and the roofer's invoice.
- Look for leftover bundles in the garage or attic.
- The release tape on the back of many shingles is printed with the manufacturer's name.
- Granule blend and the shape of the cutouts often point to a specific line.
Why it matters
The exact product decides whether repairs can match, which warranty applies, and how insurers view the roof. If a storm damages part of a roof and the shingle is discontinued, matching becomes part of the claim.
