A roof isn’t just shingles—it’s a system that protects your home from water, wind, mold, and temperature extremes. In climates like the Pacific Northwest, where roofs endure constant moisture and fluctuating temperatures, investing in a complete roofing system is essential. That’s why industry-leading contractors recommend the Owens Corning Total Protection Roofing System®. It’s designed to perform in all conditions by sealing out moisture, defending against the elements, and allowing your roof to breathe properly.
Let’s break down how this multi-layered system creates one of the most reliable, high-performing roofs on the market.
What Is the Owens Corning Total Protection Roofing System®?
This roofing system goes beyond shingles. It integrates three essential layers—Seal, Defend, and Breathe—to form a complete barrier against the most common roofing threats. When installed correctly, it enhances durability, minimizes repairs, and extends the life of your entire roof structure.
Step 1 – SEAL: Block Out Moisture Where It Starts
Water is one of the greatest threats to your roof—and your home. The first step in the Total Protection Roofing System® is creating a waterproof barrier.
Why the Seal Layer Matters
- Helps prevent ice damming, leaks, and mold
- Blocks wind-driven rain at valleys, chimneys, and skylights
- Adds an extra water-shedding layer beneath your shingles
Owens Corning Ice & Water Barriers and synthetic underlayment products form this layer. These components are carefully selected based on your home’s layout and climate. If you live in a rainy or snow-prone region, this extra protection is critical to avoiding long-term damage.

Step 2 – DEFEND: Protect Against Wind, Rain & Impact
Once sealed, the system adds an exterior defense. This includes starter shingles, high-performance Duration® or Duration Flex® shingles, and hip/ridge caps.
What Makes This Layer So Durable?
- Enhanced adhesion helps resist wind uplift
- Multi-layered coverage protects vulnerable roof zones
- Premium shingles provide superior curb appeal and long-term value
Color and style options allow you to match performance with design—so you never have to sacrifice aesthetics for protection.
Step 3 – BREATHE: Let Airflow Keep Your Roof Healthy
Moisture isn’t just an exterior threat. If warm, humid air is trapped in your attic, it can shorten the life of your roof from the inside out. The Total Protection Roofing System® includes an advanced ventilation system to prevent this.
The Benefits of Proper Roof Ventilation
- Regulates attic temperature and reduces mold risk
- Minimizes the chances of ice damming
- Protects insulation and interior roof layers
Balanced intake and exhaust systems ensure that fresh air continually replaces warm air, maintaining the structural health of your roofing system.
Why It Matters: Installation Quality + Material Selection
Even the best roofing system won’t perform if it’s poorly installed. That’s why it’s crucial to hire experienced, certified roofing contractors. At Orca Roofing & Exteriors, our crews are trained and certified in the full Owens Corning system—and every project includes a dedicated project manager.
