GAF and CertainTeed combine for a huge piece of the roofing shingle market. This comparison hits all the important factors in deciding – Quality, cost, styles, pros and cons of each option, warranties and more. Our guide also addresses the return on investment and explains when either GAF or CertainTeed shingles are a better choice for a homeowner.
Let’s put the comparison into perspective right from the start:
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.
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.
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.
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.
