Pros & Cons of IKO Shingles – Costs – Unbiased IKO Roofing Reviews

IKO asphalt shingles enjoy moderate sales volume across the US and have been one of Canada’s top brands. Most IKO shingles are sold directly to roofing contractors through distributors. In Canada, Lowe’s and other retailers sell IKO shingles to the public.

Did you know? Average IKO consumer ratings are poor, dragged down by widespread failure of organic shingles and the Cambridge AR line. The company is the target of class action lawsuits in the US and Canada. However, the defective shingle lines are no longer produced and IKO has been working hard on improving formulations across the board.

We mention this upfront because the lawsuits appear prominently in online search results for IKO shingles. Homeowners who had the defective shingles installed despise the company. The remaining reviews and ratings from homeowners are about average compared with other top brands. Warranties are slightly above average, as discussed below.

Are IKO Shingles the Right Choice for Your Home?

This guide provides a critical look at the current lineup of IKO shingles from the perspective of homeowners, home inspectors, and roofing contractors.

We believe this is the best approach to getting a well-rounded view of any shingle brand. It’s how we structured our reviews of GAF and Malarkey shingles among others.

Pros

Here are the advantages offered by this brand from various perspectives.

There are two reasons roofers suggest IKO products:

1. IKO Pro4 Complete Roofing System

A roof is far more than the outer covering of shingles. It’s built from the deck up using multiple components that work together to effectively shed rainwater and keep your home protected from nature’s elements.

Here are the 4 components of the Pro4 roof system:

1) GoldShield, ArmourGard and StormShield eave protection defend the roof against wind-driven rain and ice dams. IKO recommends eave protection in valleys and around protrusions like vents and skylights.

2) RoofGard-Cool Grey or Stormtite synthetic underlayment options are chosen based on local climate.

3) Leading Edge Plus starter strips are installed at eaves and rakes as an extra line of defense where it’s needed most.

4) Three ridge cap shingle options give roofers choices for matching the profile of the shingle.

The above listed product components and accessories are compatible with all IKO shingle lines.

Did you know? In order to be covered by IKO’s best warranty, the roof must be installed with one of the IKO hip and ridge shingle options: Hip & Ridge Plus, Hip & Ridge 12 or Ultra HP.

The above requirement is standard for most brands. Some manufacturers, like GAF, require that at least two other GAF components be used.

These requirements help the manufacturer maximize material sales per job, which helps cover their risk for giving the better warranty coverage.

No tear-off, no problem! There’s an advantage here to using IKO. Most other shingle brands require using their underlayment, and that means the best warranties are only available when the old roofing is removed (a tear-off). IKO doesn’t require a tear-off to get the better warranty.

Tile Roof Cost and Pros & Cons – Clay Vs. Concrete Tile 2020

Tiles are mankind’s oldest manufactured roofing material, with the first use of clay tiles dating back to Ancient China. Throughout history, their durability made them the go-to choice for roofs in the Middle East, Europe and Asia.

clay-tile-roof

Today’s roofing authorities are reluctant to say exactly how long new tile roofs will last — they may last forever! 😉

Pricing Details

As with all roofing materials, but perhaps not so much as with tiles, the upfront costs must be differentiated from the life-cycle costs. With the exception of some very high quality slate, clay tile is the most expensive roofing system you can get.

Count on a tile roof to cost two times as much as a wood shake roof and four times more than asphalt shingles.

Depending on your region and the product you choose, expect to pay between $12.50 and $25.00 per square foot for a ceramic clay tile roof installed.

Concrete tiles are less expensive than clay, so they would be on the lower end of the above pricing range.

The color, style, and grade of the tile you choose, including its weight and thickness, is what will determine the actual cost of materials, while installation costs will vary, depending on your location.

Total Cost Installed

On average, a typical 2,000 square feet tile roof will cost between $25,000 and $45,000 to install, depending on the profile, roof difficulty, choice of material, and location.

Note: higher-end clay tiles can cost significantly more than low-end and mid-range tiles.

It’s not unheard of for a tile roof to cost as much as $50,000 installed, especially when you deal with a complex roof requiring a lot of tile cutting and additional labor.

Historic Context and Larger Picture — Old School Tiles and Modern Revival

In the United States, tile roofing techniques traveled across the ocean with the Dutch on the East Coast and the Spanish missionaries along the Gulf Coast and out West.

Tiles were formed with clay and fired to produce the familiar orange-ish colors. Minerals could be infused into the baking process to create a colored tile and glazes could also be added to the natural Terra Cotta to increase the variety of colors.

With the abundance of trees in northern America, wood roofing soon replaced tile as a favorite house covering. Tile would go in and out of favor, owing to the vagaries of architectural styles.

In the mid-1800s, when flat-roofed Italianate villas became a momentary rage, the demand for tile surged.

In the 1920s American architects introduced Revival styles in Mediterranean, Spanish Colonial, Italian Renaissance and Mission designs which kick-started the clamor for tile roofs once again.

Today, clay and concrete are the two most common types of tiles used to cover roofs.

Clay tiles were historically hand-formed until the 1870s when tile making machines were first invented. Large manufacturing plants were then established in areas rich in clay such as the Ohio River Valley, northern Georgia and western New York.

Did you know? Today, almost all roofing tiles are machine-made.

The technology to fabricate tiles from cement became available in the 20th century. The gray concrete was impregnated with iron oxides to do duty as imitation Terra Cotta tile, imitation slate and even imitation wood shakes.

Tiles can be extruded to form nearly any shape. They can be churned out flat, as with shingles that overlap and interlock on a roof. They can be the familiar barrel style which are laid in vertical rows of half-circles. They can be S-tiles that have concave and convex troughs that overlap across a rooftop.

No matter what shape tiles take, they are among the most decorative of all choices for roof coverings.

Tamko vs. Owens Corning Roofing Shingles: Cost, Pros & Cons, ROI

Owens Corning and Tamko are two asphalt shingle manufacturers sharing the adage, “we’re second-best, so we try harder.” CertainTeed is the consensus leader for overall asphalt shingle quality.

GAF is the largest producer of shingles, and its products get high marks. Right behind those giants are Owens Corning, certainly one of the most recognizable names in roofing products, and Tamko (or TAMKO), a brand that has its fans, too.

The Bottom Line from the Beginning

The bottom line, which all the details in this guide lead to, is that the Owens Corning vs. Tamko comparison is about as even as it gets in the roofing products industry.

Owens Corning Roofing Shingles Display

Both get ratings in the “good” to “very good” range from roofing contractors who install them every day and from home inspectors who have seen their share of durable shingles and shingles that have failed before they should.

What it comes down to is the quality of the installation. You’ve got two above-average shingle brands that can deliver superior durability for 20+ years, fail in just a few years or perform somewhere in the middle.

What makes the difference is how well the installers do their job.

More on the installation below. Along the way we’ll address where each brand has bragging rights. While OC and Tamko are close to equal in total score, each brand has strong and weak points.

OC vs. Tamko: Quality and Reliability

Quality is a product of the materials used and the production process. Here’s an overview of Owens Corning and Tamko shingle construction.

  • Owens Corning: OC makes three tiers of shingles in basic (Oakridge, Supreme), better (Duration, OC’s best-seller) and best (Devonshire, Woodmoor, Woodcrest, Berkshire) categories.
  • Tamko: This brand makes a very similar lineup with basic (Elite Glass-Seal), better (Heritage, Heritage Woodgate) and best (Heritage Premium, Heritage Vintage).

All shingles from Owens Corning and Tamko feature fiberglass mat bases saturated with asphalt and dressed with coated granules to resist the sun’s UV radiation. Each shingle is constructed with fused layers.

When installed, less than half of each shingle is exposed. The result is that 3-tab roofs (OC Supreme and Tamko Elite Glass-Seal 3-tab) have 2-3 layers of coverage at any given point on your roof.

All other shingles from both brands are architectural style shingles with 4-5 layers of coverage. The result are shingles with wind ratings of 60mph for 3-tab products and 110/130mph for all others.

The two brands have the same ratings in most ASTM materials and fire rating tests. Both are on par or superior to most other brands including CertainTeed and GAF.

Bad shingles are often the result of production rather than the materials used. The production processes for these brands are similar. The processes are slightly tweaked, even from run to run (runs of shingle batches).

When errors occur, a bad batch of shingles, such as layers that don’t properly fuse, are produced. What makes a brand worth considering is the consistency of the quality from run to run. Owens Corning and Tamko deliver good consistency.

Advantage—Tie: We’re not afraid to take sides, but there’s no clear winner here. These brands are rated about as equal as you will find in terms of quality and reliability, especially the two most-popular series, the Owens Corning Duration and Tamko Heritage.

Owens Corning vs. Tamko: Cost

Since these brands compete aggressively head to head, their prices are comparable across all products (and are very competitive with GAF, too).

Here is a breakdown of the shingle series and their costs from both brands:

Prices are per square, which is 100 square feet of coverage (and 3 or 4 bundles of shingles, so check product specs for the bundles-per-square).

3-tab shingles:

  • OC Supreme: $70-$85
  • Tamko Elite Glass-Seal: $72-$77

Average architectural/dimensional shingles:

  • OC Duration: $110-$120
  • Tamko Heritage: $84-$100

Best-selling architectural/dimensional shingles:

  • OC Duration Designer, STORM & COOL: $105-$135
  • Tamko Heritage Premium: $90-$105

Premium, architectural/dimensional shingles:

  • OC Devonshire, Woodmoor, Woodcrest, Berkshire: $175-$280
  • Tamko Heritage Woodgate, Heritage Vintage: $180-$205

Advantage – Tamko: As you can see, Tamko offers better value in each tier of products. It always makes sense to get written estimates on the specific roofing materials you’re considering, to get a direct comparison of cost.
