What the AI looks for in Shingles & Shakes
- Wind resistance
- Look for ASTM D7158 Class H or ASTM D3161 Class F in high-wind areas, and follow the manufacturer's high-wind nailing pattern Shingle blow-off is the most common storm failure.
- Impact resistance
- Choose UL 2218 Class 4 where hail is frequent It reduces granule loss and cracking, and may qualify for insurance discounts.
- Fire rating
- Class A (UL 790 / ASTM E108) for asphalt. For cedar, check for fire-treated product in wildfire zones. Untreated wood shakes are restricted in many wildfire-prone jurisdictions.
- Minimum slope
- Asphalt shingles need 2:12 or steeper, with double underlayment from 2:12 to under 4:12 Below this slope, water backs up under the tabs.
- Algae resistance
- Choose algae-resistant (copper-granule) shingles in humid climates It prevents black streaking that is otherwise hard to remove.
- Color lot and coverage
- Buy all bundles from one production lot. Architectural shingles commonly come three bundles to a square (100 sq ft), but confirm on the wrapper. Color blends vary between lots, and short orders cause visible mismatches.

Questions
Do I need the same brand's starter and ridge cap?
For basic function, no. For an enhanced manufacturer warranty, usually yes.
Are cedar shakes and cedar shingles the same?
No. Shakes are split and thicker with a rough face, while shingles are sawn and thinner. Look for Cedar Shake & Shingle Bureau grade labels.
