A 3-Tab shingle is typically a 20 or 25-year shingle, while Architectural shingles are normally a 30, 40 or 50-year shingle. However, it is important to know that these are national averages and do not accurately represent the true lifespan of a shingle here in Florida, where the hot sun can shorten the life span of your roof. 3-Tab shingles normally only last 16-18 years in Florida, and 30-year shingle will last about 20-22 years. A 40-year shingle lasts about 28-30 years in Florida.
The biggest advantage of Architectural shingles over 3-Tab is the wind rating. 3-Tab shingles are rated for 60 mph winds, while Architectural shingles are rated for 130 mph winds. This can be a critical difference when a hurricane or strong wind storm comes through our area.
