Roof valleys are crucial intersections where two roof slopes converge. They play a pivotal role in directing water off the roof, ensuring it doesn’t seep into your home. Properly shingling a roof valley is essential to prevent potential leaks and ensure the longevity of your roof. At Collins & Son Roofing, we prioritize the integrity and aesthetics of your roof. Here’s a comprehensive guide on how to shingle a roof valley with architectural shingles.
Understanding Roof Valleys
A roof valley is where two roof slopes meet, acting as a channel for rainwater. The method you choose for valley installation can make a significant difference in the roof’s performance and longevity. There are primarily three techniques to shingle a roof valley: woven, closed-cut, and open. Each method has its advantages, but for optimal performance, especially in areas like Conway AR, the open valley method with architectural shingles is highly recommended.
Three Main Methods to Shingle a Roof Valley
1. Woven Valley Shingle Installation
In the woven valley method, shingles from both roof planes intertwine in the valley. While this method offers a consistent look, it’s essential to lay the shingles correctly. Incorrect installation can lead to bumps, affecting the roof’s overall appearance. The woven method doesn’t require roofing cement, but it’s crucial to ensure no hollow spaces develop under the shingles, as this can compromise the roof’s durability.
2. Closed-Cut Shingle Valley Installation
The closed-cut valley presents a sharp, clean appearance. From a distance, it appears as if the shingles form a neat line at the valley’s center. One shingle layer overlaps the other, creating a sealed barrier. This method is faster than the woven technique but relies on the shingles to protect the valley, which can be a drawback in the long run.
3. Open Valley Shingle Installation
The open valley method uses metal flashing for protection, leaving visible metal lines running down the valley. This method is not only aesthetically pleasing but also offers longevity. Metal sheds water and ice faster than shingles, reducing potential risks. For homeowners in Conway AR seeking a long-lasting roofing solution, an open valley is the ideal choice.
Step-by-Step Guide to Shingle a Valley with Architectural Shingles
- Preparation: Ensure an ice and water protector is installed along the valley. Start by centering your flashing in the valley base.
- Secure the Flashing: Nail down the flashing, ensuring you only nail the edges. Overlap each flashing piece by at least 6 inches, using asphalt plastic cement for the overlap area.
- Chalk Line Guide: Set out chalk lines along the valley to guide your shingle installation. The lines should start 6 inches apart at the valley’s top and gradually widen as they move down.
- Shingle Installation: Begin installing shingles on one roof face. As you approach the valley, overlap the shingles and trim them according to the chalk line.
- Nailing: Ensure each valley shingle is nailed at least two inches from the chalk line. Proper nailing prevents potential leaks.
- Finishing Touches: Embed each valley shingle in a 3-inch band of asphalt plastic cement for added protection.
