The home owners in Greer, SC chose to replace their roof with the CertainTeed Landmark Moire Black AR Laminate Shingles. Many home owners are unsure whether they should choose laminated architectural shingles or 3-tab composition asphalt shingles when they go for a roof replacement.
Architectural (also known as dimensional, laminated or composite shingles) are constructed with a heavier base mat which multiple layers of material are adhered to. This gives the shingles a three dimensional look. Whereas the standard 3 tab shingles contains a flat layer with no dimensional "thickness" to it. Typically architectural shingles weigh almost 50% more than the standard 3 tab shingles. Dimensional shingles were developed in the 70's for the high end home market. Home owner's were looking for an asphalt shingle product that had the architectural appearance of cedar shingles while providing the performance of asphalt.
Architectural shingles typically have a minimum of 30 to 40 compared to 3 tab shingles of 15 to 20 years lifetime warranty depending on the manufacturer. Because of the heavier construction they are less likely to warp and they provide a much better wind resistance. Standard 3 tab shingles are typically rated for 60 mph winds while most architectural shingles are rated for 80 up to 120 mph.
Today laminated shingles are available in many different lifetime warranty lengths from 30 to 50 years. Typically, the cost of an architectural is 10-20% more than the traditional 3 tab shingles. Some of the higher end 50 year products can be as much as twice the cost. Keep in mind prices vary depending on the supplier and if it's peak season the prices do fluctuate. Nonetheless, many people consider a shingle upgrade as an investment that can increase their home's value and curb appeal. Architectural are preferred enough in some communities that homeowners associations will require them.
