What Are Dimensional Shingles?
Dimensional shingles, also known as architectural or laminated shingles, are asphalt shingles with a twist. Regular asphalt shingles have three regularly spaced asphalt tabs, giving the roofing material a very repetitive pattern. Dimensional shingles have two layers of shingle material bonded together. However, random notches have been taken out of the shingle, exposing the bottom layer. This gives these new shingles a three dimensional look, with different high and low tabs.
Because of the double bonded layer, dimensional shingles actually offer more protection from wind and hail — with the heaviest grades able to withstand 120 mph winds. They also have a longer lifespan — 40 years compared to the average 20 years for the single layer asphalt shingles.
Pros of Dimensional Shingles
- Longer lifespan - 40 years compared to 20 years for single layer asphalt shingles
- More attractive - lots of colors and options available giving your roof a unique look
- More protection from wind and hail - the double layer protects from damage
- Easily available - because they are so popular, dimensional shingles are readily available
- Works on most roof types and pitches - like regular asphalt shingles, these can be used practically anywhere
Cons of Dimensional Shingles
Slightly more expensive - the double layer does add a little to the cost
May be more susceptible to mildew and algae due to the notches - all asphalt shingles are susceptible to mold and mildew because the organic material in the shingle is one of mold's favorite foods
