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 building materials suppliers and distributors like Bradco, ABC Supply, Beacon Supply, and Harvey’s Industries. IKO products are generally not sold retail to the public.

Did you know? Some IKO shingles consumer ratings are poor, dragged down by the widespread failures of organic shingles that are no longer being produced. Similar failures associated with the organic-base mat used in shingles (since replaced by the fiberglass base mat industry-wide) had also impacted other large brands in the roofing industry. Like GAF and CertainTeed, IKO was 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 on improving their roofing shingle formulations across the board. It’s worth noting that reviews of IKO shingles in the past few years have been more favorable.

We mention this upfront because the lawsuits appear 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 PROFORMAX™ Integrated Roofing Accessories

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.

IKO-PROFORMAX
IKO PROFORMAX Integrated Roofing System

IKO’s PROFORMAX™ system is comprised of four integrated roofing accessories designed to provide a multilayered roof protection that starts underneath the shingles, working from the outer edges of the roof deck upward.

IKO recommended accessories are designed to address some of the most vulnerable areas of the roof, such as the edges (eaves and rakes) where the roof’s deck and fascia or rake boards meet.

IKO PROFORMAX™ Integrated Roofing accessories include:

  1. Deck Protection – GoldShield™, ArmourGard™, IKO StormShield® Ice & Water Protectors, and IKO GoldSeam™ Roof Sealing Tape
  2. Underlayments – RoofGard-Cool Grey® or Stormtite® Non-Breathable Synthetic Underlayments
  3. Starter Shingles – Leading Edge Plus™ or EdgeSeal® Roof Starters
  4. Ridge Cap Shingles – Hip & Ridge Series or IKO Ultra HP® Cap Shingles

Deck Protection: Ice & Water Protectors

Many areas require a prescribed zone of Ice and Water protection under shingled roofs to prevent water infiltration due to ice dams and wind-driven rain. Check your local building codes to determine what is needed in your region.

IKO recommends Ice & Water protection for the roof deck at the eaves, rakes, hips, valleys, and around protrusions like vents and vent pipes, chimneys, dormers, and skylights.

  • GoldShield™ – A premium Ice & Water membrane that forms a protective seal around each nail or fastener leaving no space where water can drip through.
  • ArmourGard™ – A midrange product comprised of modified bitumen membrane that is applied as a protective layer under shingled roofs.
  • StormShield® – An economical Ice & Water membrane comprised of modified bitumen for protection from wind-driven rain and ice dams.

Fascia and Eaves: Roof Sealing Tape

  • IKO GoldSeam™ – IKO recommends applying roof sealing tape where the fascia and eaves meet, and over the seams of plywood sheets or OSB boards comprising the roof deck, before installing synthetic underlayment.

Our view is that applying the roof sealing tape over the gap where the eave and fascia board meet will deliver solid value and aid in extending the longevity of the eave and fascia board by blocking moisture and wind-driven rain, thus helping prevent rot.

Applying roof sealing tape over the seams of the plywood might also deliver some incremental value, especially if there are uneven surfaces (different heights) in between the sheets of plywood or OSB board. That said, in many ways, this step can be seen as redundant, especially on steeper roofs with smooth deck surfaces. Very few contractors actually install a roof sealing tape over plywood/OSB board seams, but it definitely won’t hurt. 😊

Synthetic Underlayments

Underlayment serves a purpose of providing a secondary level of protection aka “roof underneath the roof”. It also helps prevent asphalt shingles from getting baked onto (or “glued”) to the roof deck in the sweltering heat of summer, when the sun can literally bake asphalt shingle onto the roof deck by melting the asphalt above the deck, especially on poorly vented roofs/attics.

  • RoofGard-Cool Grey™ – In addition to providing convenient reference lines to keep shingle courses straight, the synthetic material adds a layer of protection between the deck and the shingles. This non-breathable synthetic underlayment provides a superior slip-resistant surface on which to work.
  • Stormtite™ – IKO’s economical non-breathable synthetic underlayment option. It’s significantly stronger than traditional roofing felt and easy to install.

Note: IKO Roofgard-cool grey brochure mentions that “this product is a vapor retarder, so the air space beneath the roof deck should be properly and thoroughly ventilated to avoid risk of moisture condensation”.

Pro Tip: Use a breathable synthetic underlayment whenever possible!

Our view is that you should try to avoid using synthetic underlayments that are non-breathable vapor barriers (unless your roof’s deck and attic space are very well vented) because non-breathable underlayments can trap moisture between the roof deck and the space underneath the underlayment.

The trapped moisture can eventually cause the roof deck to rot underneath the underlayment, especially in poorly vented attic spaces. Imagine a roof deck or substrate failing due to moisture-induced rotting while the outer roofing system is still in good shape. 😉

Starter Shingles

IKO recommends the use of roof starter shingles designed to be used with the first course of shingles.

Double-sided starter rolls that use high-strength sealant are a newer option that provides enhanced protection from wind uplift at the critical first course of shingles along eaves, as well as on rake edges.

Ridge Cap Shingles

IKO’s specially constructed ridge cap shingles are designed to provide a high-quality alternative to using cut-up roof shingles to protect hips and ridges. The precut cap shingles include pre-tapered headlaps and add dimension, depth, and texture to a roofline (ridges and hips).

The above listed product components and accessories are compatible with most IKO shingle lines, but there are some exceptions like the ridge cap product that is specific to Nordic shingles.

Did you know? In order to be covered by IKO’s ROOFPRO Extended Iron Clad Protection warranty, IKO shingles must be used and installed together with at least three IKO PROFORMAX Integrated Roofing Accessories. See warranty documents for details.

The above requirement is standard for most brands. For example, manufacturers like GAF, require that at least three other qualifying GAF components to be used in conjunction with GAF shingles to make your roof eligible for the extended warranty coverage.

While it could be argued that these requirements help a roofing manufacturer maximize material sales per re-roofing job, our view is that the use of the manufacturer recommended, compatible accessories can help ensure a longer lifespan of the new roof, which helps justify the extended warranty coverage from the manufacturer.

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

It is generally agreed that CertainTeed’s shingle quality is at or near the top of all fiberglass (fiberglass-reinforced mat that serves as a base for asphalt composition shingle) shingle brands.

via Pro Home 1

CertainTeed’s large selection of available asphalt shingle products includes the most luxury roofing shingle lines of any brand, plus the mid-grade architectural or dimensional shingles, and the basic 3-tab or strip shingles.

CertainTeed’s Grand Manor and Presidential Shake products are prime examples of Premium roofing shingles that have enhanced depth and differentiated appearance.

CertainTeed’s Landmark PRO roofing shingles are an example of a traditional architectural shingle designed to appear fuller and more dimensional compared to the flattish-looking 3-tab shingle. Dimensional shingles are also thicker and heavier than the basic 3-tab strip shingles.

Did you know? CertainTeed is a heavyweight brand – literally. Its shingles contain more asphalt than most.

CertainTeed shingles, even the 3-tab strip shingles, weigh 200-plus pounds per square. Most weigh 250-480lbs per square. More weight means better durability (and impact resistance).

Other brands’ shingles weigh 160-280lbs per roofing square.

But what about the price? It’s not a secret that all, CertainTeed is the most expensive brand overall. It sometimes denies warranty claims, though that’s a common complaint about all shingle brands.

Are CertainTeed Shingles Your Best Shingle Option?

Anyone researching shingles will find a lot of praise for CertainTeed roofing, along with a few horror stories.

This in-depth review provides unbiased information to help you make a well-educated buying decision.

Information in this guide is based on the perspectives of roofing contractors who install a wide range of products from different asphalt shingle brands, home inspectors that regularly check CertainTeed shingle and other roofs for potential problems, and homeowners who have lived beneath these shingles for years.

Owens Corning vs. GAF Roofing Shingles: Cost, Pros & Cons, and More

GAF and Owens Corning own the largest share of the asphalt shingle market in America, and apart from CertainTeed, another major player in the fiberglass shingles market, no other manufacturer comes close.

Most homeowners choose between GAF Timberline and Owens Corning Duration shingles. However, both brands make additional lines of shingles across the traditional and premium categories that are also worth considering. GAF offers an impressive 20 lines of asphalt shingles to choose from compared to 12 main lines of shingles from Owens Corning.

Did you know? Independent roofers are often happy to install either brand – especially the bread-and-butter lines such as GAF Timberline HDZ and OC TruDefinition Duration shingles.

What we cover in this guide: This is a complete Owens Corning vs. GAF side-by-side comparison across all the main categories that matter to homeowners. It analyzes head-to-head the shingle options, quality, prices, warranties, and specialty shingles including those with Energy Star, Cool Roof, and Class 4 Hail Impact Resistance ratings.

Let’s put the comparison between these two popular brands into proper perspective right from the start

Owens Corning focuses mostly on the mid-range architectural shingle products, although it also makes low-cost 3-tab Supreme shingles rated for 60 MPH winds, and a few premium lines like Berkshire and Woodmoor.

GAF covers the spectrum more completely with a couple of 3-tab options like the Marquis Weathermax with an 80 MPH wind warranty and seven premium designer lines like the classic Camelot II and the beefy shake-designed Grand Sequoia available in standard and Class 4 Hail Impact rated shingle options.
