How Do Open and Closed Roof Valleys Affect Your Home’s Energy Efficiency?
A roof valley is more prominent in your home’s energy efficiency than you think. Depending on the process, they help drain, protect your insulation, and make maintenance more straightforward or complex. Let’s briefly summarize how open and closed roof valleys impact energy efficiency.
Open Roof Valleys
The open roof valleys have exposed metal lighting, which makes them ideal for draining water from your roof. Here’s how they contribute to energy efficiency.
- Keep Ice Dams Away
- In colder climates, open valleys allow water to flow through foundations, helping to prevent ice that can damage insulation and reduce your home’s energy efficiency.
- Dry Insulation = Lower Bills
- When water drains appropriately, your insulation stays dry and does its job—keeping your home warm in the winter and cool in the summer. That means lower energy bills!
- Easy to Maintain
- Open valleys are much more straightforward to maintain and repair. It’s quick and easy to spot and remove issues like debris buildup, which helps keep your roof in top shape.
Closed Roof Valleys
Closed roof valleys are covered with shingles, making your roof look clean and uncluttered. But their energy efficiency depends on proper installation and maintenance:
- Handle Water with Care
- When properly installed, closed valleys can handle water more efficiently. However, water collection can cause insulation problems and leaks if improperly installed or clogged with debris.
- Short-Term Leak Protection
- The extra shingle protects against leakage from the initially closed valley. Water binding, however, can eventually lead to insulation loss.
- Can Trap Heat
- Closed valleys don’t allow as much airflow, which can be helpful in warmer climates. However, in colder climates, this keeps homes warmer in the winter and increases cooling costs.
So, Which Is Better?
Open-roof valleys are typically better for energy efficiency, especially in heavy rain or snow areas. They’re great at keeping water away and insulation dry. On the other hand, a closed valley looks beautiful and can fit well if you are aesthetically inclined.
Whatever you choose, the most important thing is the personnel installation. A well-placed roof valley—open or closed—can save you money and headaches.

What Are The Best Materials For Open Roof Valleys?
Choosing the right materials for open roof valleys is crucial to ensure durability, adequate water drainage, and a polished look for your roof. Let’s explore the top materials and why they work so well.
1. Metal Flashing: The Gold Standard
Metal is the go-to choice for open roof valleys because it’s strong, long-lasting, and highly efficient at handling water. Here are some popular metal options:
- Copper: Copper is a luxury material known for its durability, corrosion resistance, and natural beauty. Over time, it develops a unique patina that enhances the beauty and character of your roof. Although it’s a bit of an investment, it offers unparalleled longevity. Our detailed guide will help you discover the benefits of copper roofing and why it’s a smart choice for your home.

- Zinc Compounds: Zinc is another good choice. It’s naturally corrosion-resistant and has an incredible longevity. In addition, it offers a sleek, modern look.
2. Synthetic Materials: Budget-Friendly Alternatives
While metals dominate, synthetic materials can work well in specific situations:
- EPDM (Rubber Flashing): EPDM is a flexible, weather-resistant material perfect for low-rise roofing. It adjusts well to temperature changes and provides a sound, water-resistant barrier.
- Plastic Flashing: Plastic flashing made of PVC or similar materials is lightweight and economical. While it may not last as long as steel, it is a durable way to keep water out without the risk of damage.
Regarding open roof valleys, copper, aluminum, galvanized steel, and zinc stand out for their durability and performance. Synthetic materials such as EPDM and PVC can also be used for more expensive materials. Regardless of your choice, proper installation is key to ensuring that your roof valley functions properly and keeps your home safe and dry for years.
