Using a ridge cap for a corrugated metal roof is always important. These days, metal roofs are the preferred option for residential housing. Metal is better and stronger than old-fashioned roofing materials like clay or wood.
A corrugated metal roof requires the support of a ridge cap to maintain its integrity for years. As a professional with over 25 years of experience, I’ve seen firsthand how crucial proper installation is. Before starting, ensure that eave and gable trim are in place.
Ridge caps are typically the last piece installed and should be centered correctly along the roof’s peak if your roof exceeds the standard 10 to 12 feet ridge cap length, accounting for overlapping.

If you are using a corrugated metal roof at home but have not completed it with a ridge cap, read the reasons below, especially when you plan to install new roofing.
These reasons—well, more like these benefits—will be the logical explanation for why a ridge cap for a corrugated metal roof is essential. There are seven of them below, but in reality, there are more and more.

- It Locks Out Rain and Pests
A well-installed ridge cap ensures that rain and pests won’t penetrate your home through the roof. In my experience, foam closures are essential to achieve a watertight seal. I always recommend installing solid or vented closures to block any potential gaps, which prevents unwanted elements from entering.
- Lowering the Demand of Replacement Roof
A ridge cap for a corrugated metal roof is considered important because replacing a metal roof can be costly. This is why the ridges are needed. They protect the roof from excessive water and dirt, hence improving its durability.
Replacing the entire roof can really drain your savings. For this reason, a simple, affordable ridge cap is the best solution to avoid any further damage that forces you to replace the entire metal roofing.
- Keep the Metal Roof Away from Rust
Proper ridge cap installation is crucial in preventing rust on a metal roof. In my career, I’ve observed that ensuring a 6-inch overlap between ridge cap sections and applying a silicone sealant at overlaps significantly reduces the chances of rust.
Additionally, make sure to fasten the ridge cap securely with screws going through the center of every other major roof panel rib to maintain the roof’s integrity during heavy rains.
- Enhance the Shape of the Roof
If you ask what is used for a roof ridge cap with metal corrugated roofing, the best answer is to enhance the roof’s shape. The ridge cap looks lovely and adds more aesthetic value to the roof.
- Make the Roof Water Resistant
While some metal roofs may not be inherently water-resistant, adding a ridge cap for a corrugated metal roof significantly enhances its ability to repel water, effectively making it water-resistant. Water won’t stay on the roof for too long; it will flow down quickly.
- Keeps the Roof Surface Temperature Lower
Metal roofs tend to absorb heat rapidly, raising indoor temperatures. From my experience, using vented ridge caps with specialized closures can help manage the roof’s surface temperature. This not only aids in ventilation but also prolongs the roof’s lifespan by reducing thermal stress.
Using a corrugated metal roof is a wise choice these days. They are powerful and ready to protect the house’s entire structure easily. Overall, they won’t let you down.
Incorporating ridges is essential to enhancing the durability and sustainability of your metal roof. Please call your local store or roofing expert for more information or assistance.

How to Properly Install a Ridge Cap
Installing a ridge cap on a corrugated metal roof is a multi-step process. Here’s what I recommend based on my hands-on experience:
| Step | Description |
|---|---|
| 1. Preparation | Measure and cut the ridge cap to fit your roof. Remember to sand down rough edges to avoid future wear. |
| 2. Foam Closures | Use foam closures to seal gaps, preventing water and pests from entering. Vented closures allow airflow while blocking debris. |
| 3. Fastening | Secure the ridge cap using metal-to-metal fasteners. For non-vented caps, apply sealant to screws and overlaps for a watertight finish. |
| 4. Overlapping | Always overlap ridge cap sections by at least 6 inches to prevent leaks. Seal with silicone for added protection. |
