This guide is designed to provide you with comprehensive research about the strong points and weaknesses of the Owens Corning shingles.

Did you know? OC was the focus of a class action lawsuit regarding defective Oakridge Shadow shingles installed before 2006.

The suit was rejected in 2018 because “plaintiffs’ theories were too broad to show that the class would be sufficiently cohesive under the predominance requirement for class certification.”

Note: CertainTeed, GAF, Atlas and Tamko are among shingle brands that have been hit with class action suits.

Positives:

Here are the key factors besides a huge marketing budget that put Owens Corning shingles in the second place behind GAF in total sales.

The Owens Corning Total Protection Roofing System

A roof is much more than shingles. Other components protect against wind-driven rain, ice buildup, heat in the attic and other risks brought by the elements. All the major brands make a similar collection of products.

Using products from one brand ensures they’re designed to work together. It also gives you access to the best warranties from Owens Corning.

Pro Tip: You can qualify for OC extended warranty protection if you use at least three main components of the roofing system from Owens Corning. Ask your contractor to apply for the extended warranty coverage on your behalf.

OC uses the moto “Seal, Defend, Breath” to represent the Total Protection roof.

Seal: Underlayment and Moisture Barrier

OC makes standard felt underlayment (basic), ProArmor synthetic (better) and Deck Defense high performance synthetic (best).

The Owens Corning WeatherLock ice and water barrier is made in three tiers, too. The premium Flex barrier protects valleys, eaves, rakes and areas around chimneys. It’s best suited for very cold climates with frequent freeze/thaw cycles.

Defend: Starter Shingles, Roof Shingles and Hip/Ridge Shingles

OC makes starter shingles in roll and strip form that provide extra coverage at roof eaves. Five hip and ridge shingle lines match OC’s range of shingle styles.

Breathe: Roof Ventilation

This is a range of products for the soffit, ridge, and roof. The vents allow fresh, dry air to flow into the attic and hot and/or humid air to escape. Proper ventilation optimizes airflow to get rid of excess heat and moisture, which can damage your attic and roof.

OC Certified Contractors

All major brands offer certified contractor programs. Roofers in the network are trained in the installation of OC products and are given other perks.

The homeowner benefits by knowing the contractor has the experience and training OC requires. Secondly, you have the option of better warranties, though at a cost.

However, not all asphalt shingle roofing products are created equal. This guide will help you:

  • Understand the main types of asphalt shingles
  • Compare top products and brands from most popular manufacturers
  • Ultimately choose the best asphalt shingle type and style for your home

What are Asphalt Shingles?

There are many reasons for the popularity of asphalt shingles, and we’ll cover them in the pros and cons section, but the main reasons are low cost and ease of installation – the combination of low cost and fairly decent durability and longevity aka the value for the money.

Note: If you come across a discussion of organic shingles in your research, the information is likely quite old or encyclopedic. Organic shingles didn’t perform up to the expectations of quality and performance, so most manufacturers stopped making them in 2008.

Did you know? The longevity of any asphalt shingle product is determined by the shingle thickness and quality of construction. More on that below:

Composition of a modern asphalt shingle:

  1. Fiberglass mat: The core of today’s durable asphalt shingles is fiberglass mat. This material is chosen because it is lightweight, resists tearing, and holds asphalt very well.
  2. Asphalt: The fiberglass mat is run through a saturator tank where the glass fibers are thoroughly coated with hot asphalt, a petroleum-based material used for its strong resistance to moisture. The weight and toughness of the asphalt is useful for wind and hail impact resistance.
  3. Mineral granules: The part of the asphalt shingle that will be exposed to the elements is coated with mineral granules that are available in a wide range of colors.
    — Shingles can be given a single color to produce a solid-color shingle or a blend of colored granules for a more nuanced look.
    — The ceramic-coated granules also reflect the UV rays of the sun – the single worst threat to shingles.
  4. Sealant strips: Continuous or intermittent lines of raw asphalt are applied to the top part of each shingle that will be covered by the next layer installed. The sealant strip bonds the shingles together once they heat up in sun and warmth.

Did you know? The sunnier a climate is, the shorter the lifespan of the average shingle will be. One of the ways to extend the lifespan of an asphalt roof in a sunny climate such as Florida, Arizona, Texas, is to opt for a solar-reflective, light colored shingles designed to reflect solar radiant heat and UV radiation.
