Did you know? Owens Corning (OC), GAF and CertainTeed account for about 80% of all asphalt shingle sales in the US.
This Fortune 500 (#458) dominates the building materials market with about 50% of combined residential insulation and roofing material sales. 2017 revenue was $5.7 billion.
Owens Corning used to make vinyl siding until 2007, when the division was sold to CertainTeed.
Are OC Shingles Right for Your Home?
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.
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.
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.
