25 Year (3-Tab)
25 Year or “3-Tab” asphalt roofing shingles are single-layered asphalt roofing shingles typically designed to look like slate. Strip roofing shingles are usually the lightest weight asphalt roofing shingles available in the market. Built on a tough fiber glass base, each shingle provides resistance to blow-off and tearing. Strip roofing shingles are used primarily by home builders manufacturing economy priced homes or purchased by homeowners as replacement roofing shingles for homes that already have strip shingles on the roof.
30 Year/ Lifetime
Dimensional asphalt roofing shingles are manufactured as multi-layered products and provide a thicker and richer appearance on the roof (a multi-dimensional look). Dimensional roofing shingles typically are heavier weight than strip roofing shingles and usually have improved warranty protections, which can range from 30-years to Lifetime.
Class 4 shingles are designed to withstand higher winds and resist hail damage. Most insurance companies will allow for a premium discount with a class 4 installation certificate. They typically have the appearance of a Lifetime shingle.
Premium asphalt roofing shingles are usually described as laminated shingles that have a differentiated appearance or functionality from traditional dimensional asphalt roofing shingles. These products may have designs that mimic “old-world” roofing shingles, like natural slate or natural shake roofing shingles.
