Video Throwback: Proper Roof Ventilation.

August 14, 2026

A Lot Changes In 8 Years. The Importance Of Ventilation Does Not.

Last month, we found LP2 was the July Product of the Month at Best Buy Metals on this YouTube video. It was great to hear about all the benefits of our LP2 ridge vent …and it reminded us that we’d done a video on LP2 ourselves. So, here’s a throwback: It was eight years ago we produced this video on proper roof ventilation, featuring our patented LP2 ridge vent. Except for featuring Neil Westgarth as Director of Sales and Marketing (he’s now President of Marco), it still holds up, giving great information about LP2 and the importance of ventilation on metal roofs.

Why Proper Ventilation Matters On Metal Roofs.

When installing a metal roof, the roofing material itself is only part of the system. Proper ventilation plays an important role in managing heat and moisture beneath the roof and helping protect the structure over time.

For residential roofing contractors, understanding how ventilation works—and choosing products designed to support effective airflow—can help deliver a better-performing roof system for your customers.

Harnessing Natural Airflow.

Most metal roof systems rely on natural airflow rather than electric fans to move air. As warm air rises, it naturally moves toward the upper portion of the roof, carrying heat and moisture with it.

In a properly ventilated structure using products like Marco’s LP2 ridge vent, hot or potentially damaging air is exhausted through the upper roof area while fresh, cooler air enters through intake ventilation. When intake and exhaust are properly balanced, the natural movement of air helps create positive stack pressure, encouraging heat and moisture to move upward and out of the structure.

For roofers, maintaining this balance is key. Effective ventilation isn’t simply about adding an exhaust vent. The system needs a clear path for air to enter and exit so the ventilation system can perform as intended.

Digging Deeper On LP2.

One of our favorite parts of the video is that it shows the ease of installing LP2. At a glance, you can see installation is a simple, one-person process. In fact, the screw bed and industrial-strength peel and stick adhesive pre-applied to LP2 make it one of the easiest installations on the market, saving you time and helping to keep projects moving efficiently. You’ll also see our exclusive non-wicking recycled polyester material that keeps out rain, dust and pests while ventilating better than traditional fans, turbines or louvers.

The Bottom Line.

A lot has changed since we made that video eight years ago. The fact that LP2 provides you with a simple, effective way to incorporate ventilation into metal roofing projects—helping protect the structure, improve airflow, and deliver lasting quality to homeowners—has not. So, take a quick two minutes and watch this classic. Because good value never goes out of style.
