Tamko vs. Owens Corning Roofing Shingles

tamko vs owens corning roofing shingles

One of the most important decisions you can make when it comes to your home is what type of roofing shingles to put on. This decision will affect how much money you spend, how long they last, and the energy efficiency of your house.

When deciding between Tamko and Owens Corning roof shingles, there are many factors that need to be taken into consideration.

For example, if you live in an area that has heavy snowfall then it would be best to purchase a high performing ice dam membrane because these types of roofs tend not to allow water buildup.

Tamko and Owens Corning

“We’re second-best, so we try harder” is the motto of Owens Corning and Tamko, two asphalt shingle producers.

GAF is a shingle producer and its products get high marks. The two most recognizable brands in roofing products are Owens Corning and Tamko.

The Owens Corning vs. Tamko comparison is about as even in the roofing industry, with Owens Corning getting a slight edge in shingles.

Owens Corning shingles are better than Tamko Heritage shingles because they last longer and have a higher wind resistance. A new installation method can overcome a 20 MPH difference in shingle wind-resistance.

Both brands of roofing shingle get good reviews from both contractors and home inspectors. Some roofing contractors and home inspectors have given both brands of shingles ratings in the “good” to “very good” range.

The quality of a shingle installation is the biggest determinant in how long it lasts. The durability of roofing installation is dependent on the quality. Quality is an important factor in shingle installation.

Owens Corning Roofing Shingles

Owens Corning Roofing Shingles are shingles produced, sold, distributed and installed by Owens Corning. The company was founded in 1935 under the name ‘Corning Glass Works’, before changing its name to ‘Owens-Illinois’ in 1957.

It again changed its name to reflect its primary business source in 1985, when it rebranded as ‘Owens Corning’.

Owens Corning Roofing Shingles are the world’s largest roofing company, with over $4.5 billion in sales; it also holds the record for the longest running commercial roofing shingle.

Owens Corning has used many materials other than asbestos to produce their products. The first substitution material was vermiculite, and this was successful for over 40 years.

Unfortunately, Owens Corning Roofing Shingles were found to be releasing the carcinogenic mineral into the atmosphere; thus, they began to develop other materials for use in their products.

At present, one of these is a modified asphalt (developed using recycled rubber) that has been shown to have sound environmental credentials.

Owens Corning Roofing Shingles are manufactured in Toledo, Ohio; the only North American plant currently being used.

The majority of Owens Corning’s products are now also sourced from their new factory in Qujing City, China, which opened for business in 2006.

Today Owens Corning Roofing Shingles are manufactured primarily from recycled rubber and plastic, making them environmentally friendly.

The Owens Corning Fiberglass Group has developed a patented weather resistant product known as Thermafiber Concrete Board Insulation, which is made using recycled newspapers.

This insulation performs to half the strength of other materials at thermal break-downs, but boasts an impressive R-value of 6.3 per inch when dry, and 4.5 R per inch when wet.

This is largely due to its closed-cell structure that prevents water absorption at the cellular level; additionally, it reduces wall noise by 26% over standard insulation materials.

Owens Corning Roofing Shingles are also one of the few companies to have developed a product that is truly 100% recycled.

The company produces approximately 2 million pounds of reclaimed high density polyethylene (HDPE) annually, which is used in place of virgin resin to produce the shingles’ fiberglass backing.

This reduces consumption by about 7 million pounds annually, while using recycled resources.

Owens Corning Roofing Shingles are fitted using galvanized fasteners to ensure longevity and durability, with the company offering a 30-year product warranty on all of its products.

Owens Corning Roofing Shingles are available in many colours and textures, with the most common being their asphalt shingle range; these are available in three shades of brown, as well as grey.

Quality and Reliability

The shingles are made of materials that create a long lasting product

  • Owens Corning produces three different types of shingles, with the best being Devonshire.
  • Tamko is a brand that makes different levels of quality in their products.

The shingles from Owens Corning and Tamko are designed to resist UV radiation. The shingles from Owens Corning and Tamko contain a fiberglass mat base saturated in asphalt. The shingles are made with layers that can be fused together.

The roof is covered with shingles that are only half visible. 3-tab roofs have two to three layers of coverage at any given point.

Some shingles are designed for architectural purposes, with 4-5 layers of coverage. The wind ratings for shingles depend on the type of product. The two brands have the same ratings in most ASTM materials and fire rating tests.

Bad shingles are often the result of production rather than the materials used. The processes for making shingles are slightly different every time they run.

When shingles are manufactured, all the layers need to fuse together properly. Owens Corning and Tamko are brands worth considering because they provide consistent quality.

The Triple-reinforced nailing fabric and widened nailing zone provide the OC TruDefinition Duration shingles with a 130 MPH guarantee. Tamko Heritage shingles come with a 110 MPH wind uplift warranty.

The installation of Tamko Heritage shingles requires a more costly enhancement for the product to attain a 130 MPH wind uplift warranty.

These brands compete aggressively, so their prices are comparable across all products. The prices for the product are measured in square feet.

  • OC Supreme 3-tab shingles are $75-$85 and Tamko Elite Glass-Seal is $72-$77

Note: Tamko offers better value than other siding companies. Tamko is a more affordable roofing company.

If you are considering any materials for your roof, it is important to get written estimates so that you can compare the costs and benefits of different types.

Why is Shingles Warranty Important?

Until recently homeowners didn’t worry about their roof covering.

Now with the huge number of roofs damaged by Hurricanes Katrina and Rita, this past year combined with the appearance of shingles showing up in all colors, styles and shapes there has been a greater interest in shingles warranties.

Shingles are sold with warranties that promise the owner replacement of the roof covering or reimbursement for repairs if it fails prematurely or is damaged.

It’s not just homeowners affected by hurricanes who have to worry about their roofs being replaced because of storm damage.

According to data provided by Home Depot, 30% of the roofing materials they sell are for existing homes. Of those sales, 25% are to replace shingles damaged by hail and wind.

If you plan on buying a new home – or even if you’re just looking at shingles – it’s important that you know what your warranty covers and how long it lasts so you can budget for roof replacement when it’s needed.

Shingles are a long term investment, and one that should last 30 years or more if properly maintained. Before you buy shingles, know what your warranty covers and how long it lasts.

Types of Shingle Warranties

Most companies offer five-year limited warranties and 50-year pro-rated guarantees. The five year warranty covers defective materials and installation errors, but doesn’t cover normal wear and tear.

At the end of the five years you may have to pay for any needed repairs or replacement yourself.

The 50 year guarantee is a pro-rated promise that states that if your roof needs replacing after the first 40 years, the company will pay 1/40th of the cost. After year 50 you’re on your own for replacement

The Life of Shingles

Studies show that if you live in an area where winds are between 75 and 100 miles per hour, shingles will probably last 15 to 20 years. If you live in an area where the winds are milder, they could last 25 to 30 years.

If you live in an area with high winds, shingles will have a shorter life span because of the wear and tear on the roof. If you live in an area that has little or no wind, your shingles won’t wear out as quickly.

The biggest factor in the life of shingles is how many times they are replaced. If you replace your roof once every 20 years, it will last 40 to 50 years. If you replace them every 10 years, they will only last 20 to 30 years.

According to an industry source on roofing materials, “You don’t need to replace your roof because it’s worn out, but because you need a new look. Just keep that in mind when you’re buying.”

If You Have a Warranty

If you have a warranty, be sure to read the fine print and understand exactly what is covered. Don’t expect coverage for normal wear and tear, which includes damage from trees, weathering and aging.

When you read the warranty, be sure to ask yourself these questions:

  • What is covered? Is everything that could go wrong included? If not, what do I have to pay for myself?
  • How often does it need to be replaced or repaired before they will cover those costs? If it only lasts 15 years, will I have to pay for the last five myself?
  • Is there a deductible or is the entire cost of replacing it my responsibility? If you’re responsible for any costs at all, make sure what you’re getting is worth the money you’ll have to spend.
  • What about my existing shingles? Will they replace them if I change my mind and decide not to replace them?
  • If they will cover the existing shingles, how many years do I have? What happens when it runs out?
  • How long is the warranty good for? It’s better to go with a company that stands behind their product for at least 30 years. A 50- year warranty is even better.

If You Don’t Have a Warranty

  • If you buy your shingles from an independent contractor, read the warranty before you sign any paperwork. If it’s not written down, don’t expect to have much recourse if there is a problem later.
  • Once the roof is installed, check for damage or defects and have them fixed immediately. If you don’t, you can void your warranty.
  • If the company that installed the roof has gone out of business, contact their insurance company and file a claim. The insurer will most likely ask you to pay for repairs first and then submit proof of payment before they reimburse you.
  • If you install the roof yourself, be sure to watch for any problems that might arise. If you notice a leak, don’t wait until spring to fix it. Fixing leaks in winter can be difficult and dangerous.
    • It’s best to fix them as soon as possible so the damage doesn’t get worse.

OC Warranties

OC offers a variety of warranties for different purposes:

  • The non-prorated period for shingles to be installed over any roofing underlayment is 5 or 10 years, depending on the type of shingle.
  • This warranty requires the installation of Owens Corning shingles, Hip & Ridge shingles, and two other products in order to be valid. The non-prorated period on a contract is 5 or 10 years depending on the shingle.
  • The System Protection, Preferred Protection and Platinum Protection are exclusive to Owens Corning certified contractors. These warranties offer a longer period without the warranty being prorated.

You must install 2 of the 4 products listed in the Total Protection warranty for System Protection. For the Preferred Protection and Platinum Protection warranties, you must install 3 of our products with other qualifying factors

Tamko Warranties

Tamko’s warranties are straightforward:

  • The warranty for this product is 5 years during which it has 100% coverage, and then over the next 20 years it will be reduced by 5%.
  • The warranty lasts for 360 months and is 100% during the first 15 years. The warranty is reduced by 6.67% per year over the next 15 years. The wind warranty is 130mph for 15 years and the algae cleaning warranty is 10 years.
  • The warranty for a product lasts 600 months and is 100% after 20 years
  • After 5 years, the warranty is reduced by 3.33% per year over the next 20.
  • Heritage shingles have a wind warranty of 130 MPH for 15 years and an algae cleaning warranty of 10 years.

Tamko warranties can be transferred once within two years or five years. The warranty states that if the original owner wants to transfer their limited warranty, they must provide TAMKO with written notice within 30 days after the transfer.

Warranties tell you how much the company believes in their products. Both companies offer a range of products with similar warranties.

Many people have complaints with the manufacturer not backing their warranty. Homeowners find that OC and Tamko shingles don’t back up their warranties.

The installation process of roofing is important because it determines the quality. To avoid problems with your shingles, it is important to find an experienced installer. Roofing contractors that want your business are all screened and insured.

Therefore, you should get an installation warranty from your roofing contractor so that if their mistakes cause defects, they will be responsible for fixing it.
