3-tab Strip shingle: These are the most common type of shingles on the market. They have a very flat appearance and are what most people picture when they think of the word "shingle." They are available in two basic categories: 20-year and 25-year, with the 25-year shingle being available with Fungus Resistance to keep the black streaks off of the shingles.
Dimensional or Architectural (Laminated) shingle: If appearance is an influential factor in addition to function, these value-added shingles have a number of different looks and color blends to give the roof a "layered" look. These laminated shingles weigh more and are stronger than economy shingles and, as a result, offer a greater degree of wind, tear and blow-off resistance in addition to greater value and longer warranties. All are available with Fungus Resistance to keep the black streaks off of the shingles.
