Roofing Shingles Types

Asphalt Shingles: 3-Tab and Architectural

Asphalt shingles dominate the residential roofing market in North America, covering roughly 75 to 80 percent of homes. They come in two primary types. 3-tab shingles are a single flat layer with three cutout tabs, weighing 200 to 240 pounds per square with wind ratings of 60 to 70 mph and warranties of 20 to 25 years. Architectural (laminated or dimensional) shingles bond two or more layers together, creating a thicker, heavier product at 240 to 350 pounds per square with wind ratings of 110 to 130 mph and warranties from 30 years to limited lifetime. Architectural shingles have steadily replaced 3-tab as the standard product since the early 2000s due to their superior wind resistance, longer lifespan, and more appealing dimensional appearance. Both types use a fiberglass mat coated with asphalt and surfaced with ceramic-coated granules for UV protection and fire resistance.

Metal Shingles

Metal shingles are individual panels made from steel (galvalume-coated or galvanized), aluminum, copper, or zinc, stamped into profiles that replicate asphalt shingles, wood shake, or slate. They weigh 50 to 150 pounds per square, making them the lightest shingle option. Wind ratings reach 120 mph or higher depending on the interlocking system. The expected lifespan is 40 to 70 years, far exceeding asphalt. Metal shingles carry a Class A fire rating and do not lose granules or crack from freeze-thaw cycles. The tradeoff is a higher upfront cost (roughly double asphalt) and susceptibility to cosmetic denting from hail, which may or may not be covered depending on insurance policy language. Stone-coated steel shingles add a granule layer over the metal surface for an appearance very similar to traditional asphalt architectural shingles.

Composite, Rubber, and Specialty Shingles

Composite (synthetic) shingles are made from engineered polymers, recycled plastics, and fiberglass, molded to replicate slate, shake, or tile. They weigh 150 to 300 pounds per square and typically achieve both Class A fire and Class 4 impact resistance. Rubber shingles use recycled tire rubber or virgin EPDM molded into slate or shake profiles. They offer high impact resistance and flexibility in cold climates. Both composite and rubber shingles cost more than asphalt but significantly less than the natural materials they replicate. Their market track record is shorter (most products are 10 to 20 years old), so long-term performance is still being validated in the field. Wood shake shingles (cedar, redwood) were once common but have declined due to fire concerns, maintenance requirements, and building code restrictions in many jurisdictions.

Choosing a Shingle Type for Insurance Performance

For insurance purposes, the shingle type determines claim cost, premium discounts, and coverage terms. In hail-prone regions, Class 4 impact-resistant asphalt shingles offer the best combination of affordability, proven performance, and insurance premium savings. Metal shingles qualify for fire and wind mitigation credits but may face cosmetic damage exclusions for hail denting. Composite and rubber shingles with Class 4 ratings can also qualify for hail discounts, but their higher replacement cost means the claim value is larger if damage does occur. Adjusters and contractors must correctly identify the shingle type on every roof to write accurate Xactimate estimates. Replacing one type with another (such as upgrading from 3-tab to architectural or from asphalt to composite) has cost, code, and insurance implications that should be documented and communicated clearly to both the homeowner and the insurer.
