Table of Contents


If you’re in the market for a new roof or need to repair your existing roof, you’ve probably come across two of the most well-known shingle brands: IKO and Owens Corning. But who are they, and why should you consider them for your roofing needs? In this comprehensive guide, we’ll cover everything you need to know about IKO and Owens Corning shingles, from who they are to how to choose the best one for your roof.

IKO vs. Owens Corning - Background & History

IKO - Who they are

IKO is a family-owned company that was established in the 1950s in Calgary, Alberta, Canada, with the primary aim to manufacture quality roofing materials.

The company started with the production of building paper and later expanded its product line to include asphalt shingles. The turn of the millennium saw the introduction of the Cambridge series, a type of architectural shingle that became popular due to its durability and appearance. 

IKO entered the U.S. market in 1979 and built plants across North America. Their most recent plants are located in Hillsboro, Texas and Hagerstown, Maryland.

IKO who they are

Owens Corning - Who they are

Founded in 1938, Owens Corning initially began as a partnership between two major American glassworks, Owens-Illinois and Corning Glass Works, hence the name Owens Corning. The company’s primary focus was on glass-fiber technology, which led to the development of innovative products such as fiberglass insulation for homes and buildings.


In the post-war era, Owens Corning expanded its product line to include roof shingles and asphalt shingles, becoming a leading manufacturer in the roofing industry. The introduction of these products provided homeowners with durable, weather-resistant roofing solutions, contributing to the improvement of home construction standards across the United States. Owens Corning’s innovation in developing advanced roof shingles and asphalt shingles played a key role in their growth and popularity.


The company’s commitment to research and development has led to many breakthroughs over the years. In the 1970s, Owens Corning developed the first pink-colored fiberglass insulation, which not only became a popular choice for homeowners but also became a symbol of the company. In 1980, they launched their first line of residential roofing shingles.

In more recent years, Owens Corning has remained committed to creating sustainable solutions and reducing their environmental footprint. They have been recognized for their leadership in corporate sustainability by several entities such as Newsweek and Corporate Responsibility Magazine. Today, Owens Corning is a Fortune 500 company with a global reach, providing innovative products and solutions to customers in more than 33 countries worldwide.

When it comes to roofing, Owens Corning is a brand that stands out from the rest. One of their most popular lines is the Owens Corning Duration series. These shingles are built to last and provide exceptional protection for your home.

The Owens Corning Duration shingles come in a variety of types, each with its own unique features and benefits. One type are the Duration Designer shingles, which are designed to mimic the look of high-end roofing materials such as slate or cedar shake.

IKO vs. Owens Corning - Warranty Options

IKO - Warranty

When it comes to roofing, one of the most important factors to consider is the warranty provided by the manufacturer. The warranty provided by IKO on their shingles is designed to protect homeowners from any defects or issues that may arise during the specified warranty period. The warranty typically covers issues such as leaks, blow-offs, and any other problems that may occur as a result of faulty shingles. It is important to note that the warranty is subject to certain terms and conditions, so it is advisable to carefully read and understand the warranty document before making a purchase.

One of the key factors to keep in mind when looking at a warranty is its duration. The duration of the warranty can vary depending on the specific product line and the type of shingle being used. However, most IKO shingles come with a limited lifetime warranty, which offers protection for an extended period. 

Owens Corning - Warranty

When it comes to roofing materials, Owens Corning is a trusted name in the industry. One of the key selling points of their products is the Owens Corning shingle warranty. This warranty provides homeowners with peace of mind knowing that their investment is protected. 

The Owens Corning shingle warranty offers coverage for a specified period of time, typically ranging from 20 to 50 years, depending on the specific type of shingle. This warranty ensures that the shingles will remain free from manufacturing defects and will perform as intended. In the rare event that there is a defect in the shingles, Owens Corning will cover the cost of replacement materials and labor.

Not only does the Owens Corning shingle warranty cover manufacturing defects, but it also provides protection against issues caused by severe weather conditions. This includes damage from high winds, hail, and heavy rain. If your shingles are damaged due to these weather events, Owens Corning will cover the cost of replacement materials and labor.

Another advantage of the Owens Corning shingle warranty is that it is transferable. This means that if you sell your home, the warranty can be transferred to the new homeowner, giving them the same level of protection as you enjoyed. This can be a valuable selling point when it comes time to sell your home.

In conclusion, the Owens Corning shingle warranty is a valuable asset for homeowners. It provides coverage against manufacturing defects and damage caused by severe weather conditions. The warranty is also transferable, which adds value to your home. When choosing roofing materials, Owens Corning is a reliable option that offers peace of mind through their comprehensive warranty coverage.

IKO vs. Owens Corning - Who’s the Best?

Factor 1: Overall Quality

When it comes to shingle quality, there are some notable differences between IKO and Owens Corning. IKO has been in the business for over 60 years and is known for its commitment to innovation and durability. They offer a wide range of shingle options, including architectural shingles, traditional three-tab shingles, and premium designer shingles.

On the other hand, Owens Corning has a long history of producing high-quality building materials, including shingles. Their shingles are known for their durability, energy efficiency, and aesthetic appeal. Owens Corning offers a variety of shingle options, including architectural shingles, which are known for their dimensional appearance and long-lasting performance. They also offer specialty shingles, such as impact-resistant shingles and solar reflective shingles.


When comparing the shingle quality at IKO versus Owens Corning, it is important to consider factors such as durability, weather resistance, and overall performance. 


In our opinion, Owens Corning comes out ahead of IKO when it comes to quality. IKO tends to be lower-rated among roofers due to issues with their shingles not sealing properly. Owens Corning utilizes SureNail technology that imbues their shingles with enhanced adhesive power, outstanding grip and triple layer protection, which ensures your shingles will stay intact for years to come.

Factor 2: Type of Warranty Offered

IKO and Owens Corning both offer warranties for their shingles, but it is important to evaluate the terms and conditions of each warranty to determine which one provides better coverage and protection for your investment.


IKO offers a comprehensive warranty for their shingles, known as the IKO Limited Warranty. This warranty provides coverage against manufacturing defects for a certain period of time, typically ranging from 20 to 50 years depending on the specific product. In addition to this basic coverage, IKO also offers additional warranties for specific types of shingles, such as the IKO Iron Clad Protection Warranty for their premium line of shingles. This warranty provides even greater protection against wind damage, algae growth, and other common issues.

On the other hand, Owens Corning also offers a strong warranty for their shingles, known as the Owens Corning System Advantage Warranty. This warranty provides coverage against manufacturing defects and includes a limited lifetime warranty for their premium shingle products. Owens Corning’s warranty also includes additional coverage for wind damage, algae resistance, and other issues that may arise during the lifespan of the shingles. The company also offers a transferable warranty, which can be beneficial for homeowners who plan to sell their property in the future. This allows the warranty to be transferred to the new owner, providing them with the same level of protection.


When comparing the shingle warranties offered by IKO and Owens Corning, it is clear that Owens Corning provides homeowners with a better warranty overall. With longer coverage periods, higher wind resistance limits, and more comprehensive protection against manufacturing defects, Owens Corning’s warranties offer homeowners greater peace of mind and protection for their investment in a new roof.

Factor 3: Cost

When it comes to determining which shingles are more cost effective, it is important to consider both the quality and price of the products. IKO and Owens Corning are two well-known brands in the roofing industry that offer a range of shingles for residential and commercial purposes. Comparing the cost effectiveness of these two brands involves considering factors such as the initial cost, durability, and long-term performance of the shingles.


In terms of initial cost, IKO shingles tend to be slightly more affordable compared to Owens Corning shingles. This can make them an attractive option for homeowners or contractors who are working within a budget. However, it is important to note that the initial cost should not be the sole determining factor when choosing shingles. It is equally important to consider the long-term value and durability of the product.


Both IKO and Owens Corning offer shingles that are designed to withstand various weather conditions and provide long-lasting performance. However, Owens Corning is often regarded as the industry leader in terms of product quality and durability. Their shingles are known for their strength, resistance to impact, and ability to withstand high winds. While IKO shingles may be more affordable initially, homeowners may end up spending more in the long run if they have to replace their roof sooner than expected.


Another aspect to consider when determining cost effectiveness is the warranty offered by each brand. Owens Corning typically offers longer warranties compared to IKO, which can provide homeowners with added peace of mind. A longer warranty can also help reduce potential repair or replacement costs in the future.


In conclusion, when comparing the cost effectiveness of IKO and Owens Corning shingles, it is important to consider factors such as initial cost, durability, and warranty. While IKO may be more affordable initially, Owens Corning offers a reputation for superior quality and durability. Homeowners should evaluate their specific needs and budget before making a decision on which brand of shingles to choose.
