Asphalt shingles are a type of roofing material made of asphalt-coated fiberglass or paper. They are one of the most common types of roofing materials used in residential and commercial construction, and are known for their durability, versatility, and cost-effectiveness.
This guide will touch upon these key topics concerning asphalt shingles:
Advantages of Asphalt Shingles
Asphalt shingles are a popular choice for residential roofing due to their affordability, durability, and versatility. Here are some of the key advantages of using asphalt shingles:
- Cost-effective: Asphalt shingles are one of the most affordable roofing options on the market. They are a budget-friendly choice for homeowners looking to replace their roof without breaking the bank.
- Durability: Asphalt shingles are resistant to wind and hail damage, and they have a long lifespan compared to other types of roofing materials. With proper installation and maintenance, asphalt shingles can last for 20-30 years.
- Easy to install: Asphalt shingles are relatively easy to install, making them a popular choice for DIY projects. They are also lightweight, which makes them easier to handle and transport.
- Versatility: Asphalt shingles are available in a wide range of colors and styles, so you can choose the look that best suits your home. They can also be used on a variety of roofing styles, including gable, hip, and flat roofs.
- Low maintenance: Asphalt shingles require minimal maintenance and can be easily repaired if damaged. They can be easily cleaned with a garden hose or power washer, and any damaged shingles can be easily replaced.
- Environmentally friendly: Asphalt shingles are made from recycled materials, and they can be recycled at the end of their lifespan. This makes them an eco-friendly roofing option.
Overall, asphalt shingles are a cost-effective, durable, and versatile roofing option that is well-suited for many types of homes. They are easy to install and maintain, and they come in a wide range of colors and styles to choose from.
Disadvantages of Asphalt Shingles
Asphalt shingles are a popular choice for residential roofing due to their affordability and durability, but they also have some disadvantages to consider. Here are some of the key disadvantages of using asphalt shingles:
- Susceptibility to damage: Asphalt shingles are prone to damage from extreme weather conditions, such as strong winds, hail, and heavy rain. They can also become brittle and crack over time due to exposure to sunlight and heat.
- Limited color options: While asphalt shingles are available in a wide range of colors, they are not as customizable as other types of roofing materials. For example, metal roofing can be painted any color, and slate tiles can be selected in a variety of natural hues.
- Limited design options: Asphalt shingles are limited in terms of the design options they offer. They are typically available in a few basic styles, such as three-tab or architectural shingles, which may not be suitable for all types of homes.
- Poor insulation: Asphalt shingles do not provide good insulation, which can lead to higher energy bills in the summer and winter. This can be a disadvantage for homeowners in climates with extreme temperature fluctuations.
- Susceptibility to algae growth: Asphalt shingles can be prone to algae growth, which can cause discoloration and streaks on the roof. This can be unsightly and may require regular cleaning to maintain the appearance of the roof.
Overall, while asphalt shingles have some advantages, they also have some disadvantages to consider. They have a shorter lifespan compared to other types of roofing materials, and they can be prone to damage and algae growth. They also have limited color and design options, and they do not provide good insulation.
Asphalt Shingle Types
In the US, there are typically two types or categories of asphalt shingles with foundations in either organic or fiberglass materials (also called composition shingles).
Organic asphalt shingles are manufactured with a base layer of reclaimed/recycled paper and wood (aka cellulose fibers). This organic foundation is then combined with an asphalt finish and surfaced with weather resistant ceramic granules. Organic shingles typically contain more asphalt than fiberglass which makes them weigh more.
Fiberglass asphalt shingles are manufactured in a similar fashion but instead of an organic base layer, they utilized fiberglass. The fiberglass is set between the asphalt and ceramic granules. The ceramic granules protect the underlying fiberglass and asphalt layers from exposure to damaging UV radiation, resist algae, and can even save energy by reflecting the sun’s rays. They are the most common type of residential roofing shingle in use today.
Asphalt roofing shingles are relatively light, compared with other roofing options, and offer a trouble-free installation. They are typically found in three styles:
- Architectural Shingles – Also called 3-dimensional shingles or laminated shingles, are layered which creates thickness and visual depth. This roofing variety is a favorite among contractors and homeowners alike. Laminate shingles have a wind rating of 90-110 MPH
- Imitation Slate Shingles – Offers thickness, proportion, and a color selection that resembles natural slate. Natural slate can be brittle and easily damaged, imitation slate shingles are a durable, economical choice while offering a unique alternative to architectural and 3-tab.
- Three-tab Asphalt Shingles – Also called Strip Shingles are made in a single layer. They’re flatter and thinner than architectural shingles and don’t offer the visual depth and appeal. They are the most inexpensive but are also rated the lowest and offer the lowest warranty. Wind rating of 60-90 MPH.
Asphalt Shingles Installation Cost
Roofing costs will vary depending on the material and roofing contractor. Variations will typically occur based on contractor skill, location, and the time of year. In most cases asphalt shingles will be at the low end of the shingle pricing scale. Quality 3-tab laminate shingles, backed by a 20 to 30 year warranty, will cost $25 to $35 per square. Architectural shingles will offer a 40 year warranty and cost around $55 – $60 per square. There are exactly a hundred square feet in one roofing square. For example, a 10 x 10 foot area will give you exactly one roofing square. Also, expect to pay a little more for high-end colors and styles. What usually increases the cost of your asphalt roof is weight. All things being equal, the thicker the tile, the more it will cost.

Federal Energy Tax Credit for Asphalt Roofing
The Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 (HR 4853) also allows for credits in energy efficiency for 2011. The new tax credit allocates at least10% of the cost of your roof, up to $500. This credit typically only applies toward lighter roofing materials, like grey and white, that reflects the sun’s rays and ultimately saves energy by keeping your home cool. So if you had a roof done in 2011 with energy star rated roofing products, this program will lower your overall tax bill. Hopefully these rebates will also extend into 2012 as well.
Asphalt Shingle Warranty
Roofing material warranties will differ from one manufacturer to another and from one shingle to another. One of the most common warranties you will see is the 30 year warranty on many of the designer or architectural shingles. This warranty means that if in 30 years, if the shingles should fail in some way, the manufacturer will cover the homeowner if they determine the failure was caused by a material defect. If this is the case, the manufacturer will pay the homeowner a pre-determined price and then prorated it from when the warranty began. Warranties are typically always pro-rated from the time of purchase and non-transferable.
