Exploring Roofing Valley Types: Open vs. Closed Options

Have you ever wondered what lies beneath the surface of your roof? Among the roof shingles and structure, there’s a crucial element that often goes unnoticed—the roofing valley types. These valley areas or valley regions play a vital role in redirecting water and debris away from your home, ensuring its durability and strength. 

In this blog post, we’ll explore the different roofing valley types, uncovering their unique features and benefits. Whether you have a gable, hip, or shed roof, there are roofing valley types designed to cater to your specific needs of your roofing system.

We’ll delve into close valleys, and open valleys. Each type offers a distinct blend of aesthetics and functionality, from traditional craftsmanship to modern elegance.

Closed Roofing Valley: A Sleek and Seamless Choice

Let’s talk about the closed roofing valley.

This type of valley region is known for its seamless appearance, as shingles run continuously over the junction between two slopes, hiding any metal flashing from view. Closed roofing Valley comes in three popular techniques:

  1. Woven Valleys Technique: Asphalt shingles are interwoven on both sides of the valley to create a continuous flow. It looks great but can be tricky to install correctly.
  2. Closed-Cut Valley Method: One side of the valley has asphalt shingles laid up to it while the other side has them cut along the valley line. This method provides a clean look with less chance for debris buildup than woven valleys.
  3. California Valley Cut Approach: Similar to cut valleys, but with an additional layer underneath that extends across the valley. This extra layer adds protection against leaks and improves durability.

To ensure your closed roofing valley stands strong against potential leaks or damage, don’t forget to install an ice-and-water shield roofing underlayment material beneath overlapping shingle layers.

You might be wondering why you should choose closed roofing valley over open ones?

The answer lies in aesthetics – many homeowners prefer this style because it offers a smooth transition between different sections of their roofs without exposing metal flashing or liners used in open systems (more on those later).

A Word of Caution

While closed valleys look great, they may not be as durable or long-lasting as their open counterparts. Debris can accumulate in the valley area, leading to potential damage and leaks over time. So if you’re going for this option, make sure to keep an eye on your roof’s condition and perform regular maintenance.

In summary, closed roofing valley is a stylish choice that can enhance your home’s curb appeal while providing adequate protection against leaks – just remember to stay vigilant with upkeep.

Key Takeaway: 

Closed roofing valley is a popular choice for homeowners due to their seamless appearance, with shingles running continuously over the junction between two slopes.

They come in three techniques: woven valley, closed-cut valley and California cut valley approach. However, it’s important to note that closed valleys may not be as durable or long-lasting as open ones and regular maintenance is necessary to prevent potential damage and leaks caused by debris accumulation.

Open Roofing Valley: The Durable and Efficient Choice

Are you considering different Roofing valley types for your project? Let’s take a closer look at open roofing valleys, a popular choice among roofing professionals.

But what makes them so popular?

The answer lies in their unique design, which promotes better water runoff and increased durability compared to closed valley systems.

V-Shaped Metal Valley Liners

In an open valley system, V-shaped metal liners are installed directly into the juncture between adjacent slopes. This creates a seamless channel for water to flow off your roof with ease, reducing debris buildup and potential leaks over time.

W-Shaped Metal Valley Liners

Another option is W-shaped metal liners, which provide similar benefits as V-shaped ones but offer additional protection against wind-driven rain infiltration due to their double-layered design.

Easier Water Runoff

  • Open roofing valley allow for faster drainage of rainwater from your roof surface thanks to their unobstructed channels created by the metal liners.

Durability and Longevity

  • The use of metal flashing in open valleys reduces wear and tear caused by debris accumulation, resulting in longer-lasting performance than closed valleys.

Better Leak Resistance

  • Metal liners also help prevent leaks at the junctions between slopes since there are no overlapping shingle layers involved like in closed valley systems.

If you’re looking for a roofing valley system that’s durable, efficient, and low-maintenance, open roofing valleys might just be the perfect choice for your project. However, it’s essential to consult with professional roofing contractors who specialize in this area before making any decisions based on personal preferences alone.

This article provides an excellent comparison of open and closed valley systems to help you make an informed decision.

In summary, open roof valleys offer superior performance due to their design, which promotes easier water runoff while providing increased durability and leak resistance compared to closed valley systems.

Key Takeaway: 

Open roofing valley is a popular choice among roofing professionals due to their unique design that promotes better water runoff and increased durability compared to closed valley systems.

V-shaped or W-shaped metal liners create seamless channels for water flow, reducing debris buildup and potential leaks over time. Open roof valleys offer superior performance with easier water runoff, increased durability, and leak resistance compared to closed valley systems.
