What Are Roof Valley Systems For Residential Asphalt Roofing?

When we talk about residential asphalt roof replacement, one of the terms you’ll hear a lot is “roof valley.”

A roof valley is simply the space where two planes of your roof meet. If you’re looking at a roof, it’s basically the line where the surfaces join together.

As you can imagine, there has to be a method to place shingles over this section of the roof. Otherwise, your roof would be susceptible to water damage and all sorts of corresponding issues.

The roof valley is one of the most difficult parts of roofing to get exactly right. It’s the section of your roof where problems will most likely crop up if something doesn’t go right later.

At RoofSmart, we focus on getting every single little detail right, so the big picture of your roof comes together perfectly. If those details aren’t right around your roof valley, you’ll be in trouble later on. That’s why it is so important to choose a roofing contractor that you trust.

Open Valley Roof Systems Are A Versatile Choice For
Residential Asphalt Roofing In Sammamish, WA

What are open valley roof systems?

When we talk about an open valley roof system, we’re referring to a method of placing shingles over the valley of your roof.

Open valley roof systems are one of the most common and functional systems for residential asphalt roofing.

A lining, usually metal, is placed along the valley, and shingles are cut back around that lining. Metal can be a tough roofing material to work with – but not here. We’re experts on metal roof products.

What are some pros of an open valley roofing system? This style is fantastic for water and snow runoff. Water and debris can run right down the lining and flow out in your gutters. Also, this style is versatile and clean-cut.

On the flip side, open valley systems can be a little more expensive to install. They require more material and work than a closed valley roofing system.

It’s not a bad idea to invest in your roof from the start with the most effective roofing system. You’ll likely save on repair costs later on. Even so, different methods of installing residential asphalt roofing exist for a reason – more than one thing works.

Closed Valley Roof Systems Are A Budget-Friendly Option For Residential Asphalt Roofing Replacements

Looking for a method that will hold up decently but save a little bit of money on the front end?

That’s where closed valley roofs come in.

For this roof system, shingles are installed to slightly overlap in the valley of the roof. This leads to a streamlined look over the roof valley.

Especially for residential asphalt roofing, closed valley roof systems can lead to slightly more debris getting caught in the valley of your roof. However, it’s a decent option that is usually more budget-friendly than an open valley system.
