  • Understand the main types of asphalt shingles
  • Compare top products and brands from most popular manufacturers
  • Ultimately choose the best asphalt shingle type and style for your home

What are Asphalt Shingles?

There are many reasons for the popularity of asphalt shingles, and we’ll cover them in the pros and cons section, but the main reasons are low cost and ease of installation – the combination of low cost and fairly decent durability and longevity aka the value for the money.

Note: If you come across a discussion of organic shingles in your research, the information is likely quite old or encyclopedic. Organic shingles didn’t perform up to the expectations of quality and performance, so most manufacturers stopped making them in 2008.

Did you know? The longevity of any asphalt shingle product is determined by the shingle thickness and quality of construction. More on that below:

Composition of a modern asphalt shingle:

  1. Fiberglass mat: The core of today’s durable asphalt shingles is fiberglass mat. This material is chosen because it is lightweight, resists tearing, and holds asphalt very well.
  2. Asphalt: The fiberglass mat is run through a saturator tank where the glass fibers are thoroughly coated with hot asphalt, a petroleum-based material used for its strong resistance to moisture. The weight and toughness of the asphalt is useful for wind and hail impact resistance.
  3. Mineral granules: The part of the asphalt shingle that will be exposed to the elements is coated with mineral granules that are available in a wide range of colors.
    — Shingles can be given a single color to produce a solid-color shingle or a blend of colored granules for a more nuanced look.
    — The ceramic-coated granules also reflect the UV rays of the sun – the single worst threat to shingles.
  4. Sealant strips: Continuous or intermittent lines of raw asphalt are applied to the top part of each shingle that will be covered by the next layer installed. The sealant strip bonds the shingles together once they heat up in sun and warmth.

Did you know? The sunnier a climate is, the shorter the lifespan of the average shingle will be. One of the ways to extend the lifespan of an asphalt roof in a sunny climate such as Florida, Arizona, Texas, is to opt for a solar-reflective, light colored shingles designed to reflect solar radiant heat and UV radiation.

Types and Styles of Roofing Materials

The material options presented below cover more than 95 percent of all residential roofs in the United States.

Asphalt/Fiberglass Composition Shingles

More than 75 percent of all single-family homes in the US are covered with asphalt shingles, though that number is slowly shrinking thanks to the more energy-efficient and durable materials like metal.

Asphalt (composition) shingles dominate the market because they are affordable, offer a variety of attractive options, and do a good job protecting homes from the nature’s elements.

There are two main types of asphalt shingles:

  • Fiberglass shingles start with a fiberglass mesh mat that is covered in asphalt and topped with granules that provide color and reflect some of the sunlight. Shingles made with fiberglass are lightweight and resist tearing.
  • Old-school organic asphalt shingles (almost non-existent today) would normally have paper, an organic material, saturated in asphalt and covered with granules. The shingles are heavier and harder to work with than fiberglass, but they generally offer better stability in high winds. Although you can still see them on many roofs, organic shingles have been mostly phased out or discontinued over the course of last decade. Why? Manufactures have stopped making organic shingles due to their tendency to dry out, become less-waterproof and more prone to excess moisture absorption.

Pros and Cons

The advantages of asphalt shingles are:

  • Fiberglass shingles offer good fire protection
  • Look good on most any style home
  • Shingles are often the most affordable roof covering option, especially in good/better ranges
  • The best asphalt shingles are a 30-year roof solution installed on homes located in moderate climates
  • The cheapest 3-tab shingles are an affordable way to dress up a home before putting on the market
  • Broad selection of colors and styles including affordable three-tab and architectural shingles that mimic shakes and slate
  • DIY asphalt shingle installation is possible for those with good skills, experience, and equipment
  • No support beyond standard roof sheathing is required for shingles
  • 3-tab shingles are rated for 60-70 MPH wind uplift, while standard architectural shingles are rated for 110 MPH winds; high-wind shingles are rated for 130 MPH
  • High-impact shingles such as the ones manufactured by GAF should be used for heavily wooded locations and areas where large hail is possible
  • Some shingle repairs are easy and cost-effective

A few words of caution:

  • The lifetime cost of shingles is higher than metal, tile, or slate, because composition shingles must be replaced more frequently
  • Cheaper or low-end asphalt shingles like 3-tab or strip shingles may last only 10-15 years in hot, sunny climates like Arizona and Texas
  • Rapid temperature changes can cause asphalt shingles to crack prematurely
  • A poorly vented attic will trap heat and significantly shorten asphalt shingle lifespan by cupping or cracking them
  • While the asphalt shingle industry boasts that its products can be recycled for paving, few recycling facilities take asphalt shingles, and they are among the least eco-friendly roofing options
  • After a second layer of shingles needs replacing, all layers must be torn off the roof, creating extra expense and a lot of potential landfill waste
  • Mold or algae can be a problem on shingles in shady areas, unless treated with anti-algae/anti-stain treatments
  • Organic/felt shingles are heavy; getting them to the roof in bundles can be a challenge

Wood Shingles and Shakes

Wood delivers a natural dose of beauty to any roof. Cedar, redwood, cypress, and pressure-treated pine shingles and shakes are available.

How are wood shingles and shakes different?

  • Wood shingles are machine-cut and feature cleaner edges and a smooth surface to produce a more uniform appearance.
  • Wood shakes are hand-cut from blocks of wood, so have a more rustic appearance. They’re thicker too, so slightly more expensive than wood shingles.

Pros and Cons

The advantages of wood shingles and shakes are:

  • Wood has natural beauty that ranges from rustic shakes to handsome, neat shingles
  • Cedar and redwood contain oils that make them naturally resistant to moisture and insects
  • Treated wood shingles have a Class A fire rating
  • Cedar shingles and shakes can last 5 to 10 years longer than asphalt when properly maintained, which makes them competitively priced with asphalt over their lifespan
  • Wood has an insulation value twice that of asphalt shingles. However, your home’s insulation levels including walls and attic are far more important than the R-value of the roof covering
  • Many shakes and shingles are made from salvaged trees – those that have fallen over from age or were toppled by storm
  • Wood is recyclable into wood chips, mulch, or compost
  • They enhance a range of architectural styles including Tudor, Victorian, Cape Cod, bungalow and cabin/cottage

Keep these potential disadvantages in mind:

  • Non-treated materials have a Class C fire rating, but wood can cedar shingles and shakes are also available as a more-costly treated option
  • Wood roofing is prohibited in some areas prone to wildfire, so be sure to check with your building department first
  • Untreated wood shakes and shingles are high maintenance – they need to be cleaned consistently to prevent the growth of algae or moss, and debris needs to be cleared to allow the wood to breathe
  • While DIY installation is possible if you have good experience, faults in the installation can lead to quick deterioration of the roof which often includes serious leaks
  • Staining of the shingles and shakes might occur as natural factors cause tannins to be released from the wood
  • While wood is quite durable, but repairs will be expensive if they are required

2021 Steel Roof Costs, Pros & Cons – Steel Roofs vs. Asphalt Shingles

For many decades, composition shingle roofs have been the overwhelmingly popular choice for new roof installations and re-roofing applications.

However, thanks to the rapidly growing consumer awareness of all the benefits of modern residential metal roofing, many savvy homeowners are now considering steel sheet panels and stamped tiles as a viable alternative to asphalt shingle roofs. Hence, it is hardly a surprise that metal, which is by and large steel, has become the fastest growing segment in the residential roofing market.

Why Steel Roofs?

Many homeowners concerned with aesthetic appeal are often positively impressed with the wide variety of contemporary styles, profiles, and vibrant colors available in modern steel roofing. Other benefits that help make steel roofs stand out among other roofing products, include low overall life-cycle cost, durability and longevity, superior energy efficiency, and sustainability.

For anyone who wants their roof to be an asset for years to come, rather than it being a constant source of problems, steel roofing can be a wise choice.

Steel is Exceptionally Strong and Durable

Steel is one of the strongest, most durable building materials, which is why it is so widely used in commercial and industrial construction. Your home can benefit from superior durability of steel in several different ways; The inherent material properties of steel make it highly resistant to cracking, warping, curling, or peeling — all of these are common problems associated with asphalt shingles.

Did you know? A steel roof will not be susceptible to rot, decay, discoloration, mold growth or termite infestation. The superior durability of steel will free you from the expensive and time consuming maintenance and repair issues that are often a necessary part of owning most other types of roofing systems.
