An architectural shingle gives a 3 dimensional, textured, and layered appearance to a roof. This is done by increasing the profile of the shingle with thicker layers and the addition of more asphalt granules. The effect is a very aesthetically pleasing roofing system that is better resistant to the elements.

Here are a few examples of true architectural shingles.

Architectural shingles are a more heavy duty shingle when compared to their closely related, 3 tab cousins. Their base layers of fiberglass matting are thicker and more robust. They have a heavier coat of asphalt covering them. This makes them more resilient to lifting by wind. They are also better equipped to withstand being hit by hail.

The heavy duty nature results in a heavier product. It is approximated that per 100 square feet of roofing surface area, an architectural shingle adds more than 100 lbs of weight to a roof. Added weight is not all that the shingle will add however. The lifespan also increases dramatically.

An architectural roof is estimated to have a lifespan of 24-30 years. That is significant when compared to a 3 tab roof with only 15-20 year expectancy. Some architectural shingles are expected to last up to 40 years.

Atlas Chalet: Robust Appearance On A More Simple Platform

The atlas chalet can be considered a look alike product of the architectural shingle. The 3 dimensional appearance is present. The base platform is not however comparable to the heavy duty fiberglass matting that the architectural shingles benefit from. The chalet is built on a 3 tab asphalt shingle model.

Some of the problems associated with the atlas chalet are based on the inability of 3 tab shingles to withstand high wind environments. This is why wind damage claims are common with the atlas chalet.

Here are some examples of atlas chalet shingles seen from a short distance.
