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. 2020 revenue was over $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.

Note: Comparing residential asphalt shingle brands is easy with the guides we’ve prepared for GAF, CertainTeed, Atlas, Malarkey and an Owens Corning vs Tamko guide.

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.

Average Roof Lifespan – How Long Does a Roof Last?

If you are in the process of buying a new home, you probably want to know the age of the roof and how much longer it will last. Similarly, if you’ve lived in your home for a while, you are probably also wondering about the current condition of the roof and whether it’s time to consider some viable replacement options.

Curled-up shingles

This guide outlines the expected lifespans of most popular roofing systems for homes. Print it out and use it to assess the life expectancy of any roof when buying a new home or planning for future roof replacement needs in your own home.

Right Off the Bat: A typical asphalt shingle roof will normally last anywhere from 15 to 25 years (and up to 30+ years in some rare cases) before requiring a replacement.

That said, there are several different kinds of asphalt shingles, as well as other roofing materials to consider when estimating longevity of a particular roofing system. Let’s get started.

Average Lifespans for Most Popular Residential Roof Systems:

  1. Asphalt Shingle
  2. Metal Roof
  3. Tile Roof
  4. Cedar Shingle and Shake
  5. Natural Slate
  6. Synthetic composite roof
  7. EPDM Rubber flat roof
  8. PVC single-ply membrane
  9. TPO membrane

1. Asphalt Shingles

3-tab or 25-year Shingles shingle is the most basic and least costly asphalt roofing option for slopped residential roofs. A typical 3-tab asphalt roof will last anywhere from 10 to 20 years, depending on the environment and slope of the roof.

Cracks or thermal splitting in asphalt shingles

3-tab shingles are an OK option for temperate climates, but they are not at all suitable for storm-prone areas like Florida. The maximum wind-uplift a 3-tab shingle roof can withstand is 60 MPH to 70 MPH.

Note: When exposed to strong, direct sunlight and rapid temperature changes i.e., thermal shocks that are commonly associated with southern states and desert climate zones — think places like Texas, Arizona, Oklahoma, Nevada, and parts of California that are mostly deserts — asphalt shingles can develop cracks, resulting in a greatly diminished lifespan and premature failure.

Architectural aka 30-Year and 40-year Dimensional or Laminate Shingles are thicker and hence more durable and longer lasting than their entry-level counterparts, three-tab strip shingles. Most architectural shingle roofs will last anywhere from 15 to 25 years, depending on the environment.

Maximum wind uplift for most architectural shingle products is 110 MPH. With an enhanced 6-nail installation method and roof-frame bracing, the wind uplift rating can be increased to 130 MPH. The one exception is the GAF’s Timberline HDZ shingle that comes with the standard 130 MPH warranty, even when installed using the standard nailing method.

50 Year Premium Shingles are normally fancier-looking asphalt shingles designed for premium homes. A premium shingle is normally thicker and will last longer than a mid-range architectural shingle. Expected lifespan of a premium shingle roof is anywhere from 20 to 35 years with proper maintenance, depending on the environment.

Wind uplift ratings for premium designer shingles are similar to architectural shingles. Premium shingles (like architectural shingles) can also include special properties such as enhanced solar reflectance aka CoolRoof rating and hail impact damage resistance for hail prone areas.

Tell-Tale Signs to Consider a Full Replacement: If the asphalt shingles on your roof have developed major cracks, lost a lot of sand granules, are chipping and look dried-up or curled up, then you know it’s time for a new roof.

If the shingles are still in a seemingly good shape, but the roof has sustained significant storm or hail damage, then it’s probably time to consider replacement or partial replacement.

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

GAF is at or near the top of the best-selling asphalt shingles list. Is GAF’s enviable market share the result of consistent quality and performance, or is it driven by a large marketing budget that helps cover its flaws? Let’s explore.

There are obvious things to like about GAF – the wide selection of asphalt shingle styles and colors are sold nationally, and if you need more of the same shingles five or ten years later, they will likely be available.

On the downside, it is well documented that GAF, like most other shingle manufacturers, sometimes denies warranty claims that seem legitimate. The company settled a major class action lawsuit over warranty claims on defective shingles manufactured from 1998 to 2009, primarily at one plant. Let’s dig deeper.

Are GAF Shingles the Right Choice for Your Home?

This investigative look at GAF shingles is for homeowners who are considering GAF products and want to do their due diligence before making the roofing material decision.

This gives you the perspective of contractors that have installed GAF shingles for decades, home inspectors that have inspected hundreds of GAF-covered homes, and homeowners that live with GAF shingles on their roof every day.

Pros

Let’s look at the GAF shingle pros from the three perspectives mentioned: Installers, inspectors and homeowners.

Why roofing contractors like GAF shingles: There are a couple reasons that most roofers are happy to install GAF products, and some swear by them.

  • The GAF complete roofing system: When you purchase mechanical systems, an HVAC system for example, it’s important that the components such as the condensing unit, indoor coil, gas furnace and the thermostat control are designed to work together. The result is optimized performance.
