Asphaltic Composition Roofing

The Affordable Pitched Roofing Option

Pewaukee Building with Asphalt ShinglesAsphalt shingles are currently the most popular type of roof material for a variety of reasons. They are relatively inexpensive and used extensively in commercial and residential roofing markets. While asphalt shingles are very simple to install, but attention to specific details like chimneys, penetrations, valleys, building joints and other complex areas are a must. This makes installation by a trusted and professional company, such as Roofed Right America, an attractive proposition compared to paying 10% less for a fly-by-night contractor who will never come perform service work if needed.

Asphalt come in a variety of colors and styles, are fairly durable (some have been tested and achieved a class IV hail rating - the highest available!), and can be easily repaired and maintained.

How Long Do They Last?

The lifespan of asphalt shingles depends highly upon the environment. Shingles in cooler climates seem to last longer than those installed in warmer climates. Studies have shown that the average lifespan for a 20 year shingle in Phoenix, Arizona, is around 14 years. In Minneapolis, Minnesota, the lifespan was 19.5 years. And in Reading, Pennsylvania, the lifespan was 20.8 years.

From this data it seems obvious that the hotter the environment, the shorter the service life of asphalt shingles. This is great news for Wisconsin companies looking for a long-lasting roofing material.

How Expensive are Asphalt Shingles?

Things that determine cost are:

  • Geographical location of your property
  • Slope of the roof
  • Height of the building
  • Ease of access to the premises
  • Complexity of the project
  • Particular type of shingle
  • Numerous other factors

How Durable Are Asphalt Shingles?

Warped Asphalt ShingleWith such a long lifespan, it’s no surprise asphalt shingles are so popular. They are also very durable to most weather conditions, including hail.One thing very damaging to shingles is Thermal Shock, when the ambient temperature changes dramatically within a very short period of time - usually 24 hours. Roofing materials are unable to expand and contract in such a short period of time so cracks and splits start occurring. Water can then enter the materials and damage them further. One way water damages these shingles is the freeze-thaw cycle. In winter, melted snow and ice water will get into the cracks in shingles and then freeze during cold nights. Water expands as it freezes so the cracks and splits get bigger with each freeze. This is why most roofing contractors and consultants are such big advocates of sloped roofs to help shed water.

Still another factor affecting asphalt shingle roofs is attic ventilation. Proper roof ventilation has been known to extend the service life of a roof. Whether it is because it has a direct effect on the shingle themselves or on the other components such as the roof deck is uncertain.

What Are Asphalt Shingles?

Asphalt comes in two basic types: glass fiber (a.k.a. fiber glass) and organic. Organic shingles consist of an organic felt material which is generally paper saturated with asphalt to make it waterproof. A top coating of adhesive asphalt is then applied and the ceramic granules are embedded. Organic shingles contain around 40% more asphalt per square (100 sq. ft.) than their glass fiber counterpart which makes them weigh more and gives them excellent durability and blow-off resistance.

Glass fiber shingles have a glass fiber reinforcing mat manufactured to the shape of the shingle. This mat is coated with asphalt which contains mineral fillers. The mat is not waterproof by itself as its purpose is reinforcement. What makes the glass fiber shingle waterproof is the asphalt. However, the asphalt itself will not stick to the mat. For this reason, "fillers" are used so the asphalt will cling to the glass fibers in the mat. The asphalt then encapsulates the glass fibers, fills all of the little holes and voids in the mat rendering it waterproof. After this cools a bit, adhesive asphalt is used to cover the mat and the ceramic granules are embedded.

The ceramic granules are there for two reasons: to protect the shingles from the sun and for aesthetics. The sun's UV rays are very damaging to asphalt and cause it to deteriorate prematurely. This is one of the same reasons gravel is used on built-up roofs. These protective granules are available in a wide variety of colors to match almost any facade or landscape.

Improve Your Commercial Property with Asphalt Shingle Roofing

By far, the more popular shingles are the glass fiber ones. This may be attributed to the fact that they are cheaper and easier to manufacturer than organic shingles; making them more cost effective to the homeowner. It may also be that they are easier to work with, or they may simply be a personal preference of the roofing contractor.
