What are 30 year shingles?
Also know, what are 30 year shingles made of?
Roofers refer to a shingle as 3-Tab because it is made up of three individual tabs that are a 12” wide. 3-Tab shingles come in either 20yr, 25yr, or 30 yr warranties. Like Architectural shingles, 3-Tab roofing shingles are asphalt-based products that work by shedding water to the shingle below.
In this way, what is the difference between 20 year and 30 year shingles?
The larger your roof, the larger difference there will be between the 20-year shingles and the 30-year. The 3-tab, or 20-year shingles look flat because of the way they lay. Choosing architectural or 30-year shingles will give your roof more dimension. The shadow line is what gives the appearance of depth.
Today, one square of 30 year architectural shingles costs about $78 (without tax). One square of 3 tab shingles costs about $65. If you do the math, the shingles for an architectural roof replacement will cost $3,120. The shingles for a 3 tab roof will cost about $2,600.
