A Bit of History About Asphalt Shingle Roofs
Asphalt Shingles are an American invention by Henry Reynolds. Initially, Asphalt roofing came in the form of a roll without the granule coating. In 1987 slate granules were added to the surface to make it more durable. Types of granules tested over the years have included mica, oyster shells, slate, dolomite, fly-ash, silica and clay. It wasn’t until 1901 that the Asphalt roofing was first cut into strips to create the one-tab and multi-tab shingles we know today.
In the 1920s, the popularity of Asphalt Shingles shot through the roof (excuse the pun!), when the National Board of Fire Underwriters campaigned to reduce the use of wooden shingles in favour of more fire-resistant materials. Then, with the post-war housing boom of the 1940s and 1950s, and the invention of adhesives to speed up installation and improve wind resistance and durability, they became one of the most common roofing materials.
Asphalt Shingles have been in New Zealand for over 40 years and today most of the first generation tiles have become brittle and are easily lifted by high winds, indicating the end of their useful life.
Asphalt Shingle Materials
Asphalt Shingles were originally made with a base of organic felt from cotton rags. Later cellulose fibers from recycled paper and wood were tested and eventually in the 1960s manufacturers began to use fiberglass. While at first this material looked set to fail due to its light weight and therefore low wind resistance, new technology in the 1970s meant that fiberglass became the material of choice for Asphalt Shingle bases. Since the 1980s there has been numerous technological advances leading to better and more resistant shingles.
Organic Asphalt Shingles – these are still made with a base of materials such as waste paper, cellulose, wood fibers. They are saturated with Asphalt to make them waterproof and then a top coating of adhesive Asphalt is applied before being covered with solid granules. Organic Asphalt Shingles contain around 40% more Asphalt per square ft than fiberglass shingles. The downside to organic Asphalt Shingles is that they are more prone to fire damage.
Note: organic Asphalt Shingles produced before the 1980s may contain asbestos.
Fiberglass Asphalt Shingles – Fiberglass Asphalt Shingles have a base layer made from wet, random-laid glass fibers bonded with urea-formaldehyde resin. This mat is then coated with asphalt containing mineral fillers to make it waterproof. Fiberglass Asphalt Shingles are less brittle and more fire resistant than organic Asphalt Shingles.
The exposed surface is impregnated with slate, schist, quartz, vitrified brick, stone, or ceramic granules, and the under-side is treated with sand, talc, or mica to prevent shingles from sticking to one-another before use. The top surface granules block ultra-violet light, which causes the shingles to deteriorate, provides some physical protection of the asphalt core, and provides colour – lighter shades are preferred for their heat reflectivity in sunny climates, darker in cooler climates for their absorption.
Different Varieties of Asphalt Shingles in New Zealand
The main design options are 3-tab or architecture (laminated).
3-tab Asphalt Shingles – These are the original asphalt shingle. They are flat and uniform in appearance and one of the cheapest roofing options out there. Most 3-tab shingle roofs will be warranted for 20-25 years and have a maximum useful lifespan of about 30 years.
Architectural (laminated) Asphalt Shingles – These shingles are a multi-layer, laminated shingle which makes them thicker and gives a more varied, contoured visual effect to a roof surface. They also add more resistance to water. These shingles are designed to avoid repetitive patterns in the shingle appearance and can mimic natural materials such as slate. Laminated shingles are heavier and more durable than traditional 3-tab shingle designs. Many good quality, well-installed architectural asphalt shingles can be warranted for up to 50 years.
A great advantage of Asphalt Shingles is that they come in a variety of colours, shapes, and textures. Manufacturers are now able to create Asphalt Shingles to mimic almost any other material such as shake, slate, or tile. While these looks cost more than other types of Asphalt Shingle, they are still cheaper than the natural materials. They are also lighter and don’t need the added structural supports that heavier roof materials need.

Common Issues With Asphalt Shingle Roofs
As your roof is exposed to the elements and ages over time, there are some common issues that you might start to notice. It is important to inspect and maintain your roof regularly and address any issues early to help keep your roof in good condition and avoid unnecessary costs further down the line.
Common issues include:
Small blisters are considered part of the ageing process. However, if your roof is new and you experience this, it may be due to a manufacturing defect.
Curling (or buckling) is usually a moisture-related issue. This is caused by moisture getting into the shingle during the manufacturing process or by poor ventilation. If you get to this early, the affected shingles can be repaired. If this is a severe issue on your roof, you may need to have your whole roof replaced.
Raised shingles are caused by incorrect installation when the roofer hasn’t used the right number of fasteners in the right places, for example. It is important to use a knowledgeable, experienced, and certified roofing company from the outset to make sure you don’t incur higher costs further down the line. This also ensures your manufacturer’s warranty remains valid.
Cracking, tearing, or splitting
This is part of the ageing process but can also be caused by high winds, stress, and extreme temperatures. Regularly check for cracks and tears when you inspect your Asphalt Shingle roof and address them early. When left undetected, cracks and tears can let moisture in and lead to further damage including leaks.
Towards the end of its life, your Asphalt Shingle roof will naturally start to lose its granules. If you notice balding shingles or a build-up of granules in your gutter, it is important to address the issue early to ensure the integrity of your roof. Depending on your roof, a professional may advise you to replace your entire roof or they may be able to offer a re-roofing option, which adds a layer of new Asphalt Shingle on top of your existing roof.
