What Is The Valley Of A Roof? (Homeowner’s Guide)

by | Jan 16, 2023 | Blog | 0 comments

When you think of the word “valley,” you’re probably envisioning green hills flanked on either side by mountains. We’re willing to be that you aren’t necessarily thinking about your roof.

So, we know what you’re thinking. What on earth is a roof valley?

While roofers know that most roofs are made up of a combination of unique features that require special care and attention, most homeowners are unaware. This can lead to improper maintenance and damage down the road.

Today we’ll be breaking down everything you need to know about your roof valleys, from what they are and how to maintain them.

WHAT IS A ROOF VALLEY?

A roof valley is a common architectural feature in many homes. Roof valleys are created when two sloped roofs meet at an angle. This allows water to easily run off the roof instead of getting stuck and pooling, leading to eventual water damage.

Roof valleys also guard against snow and debris like leaves collecting on your roof. These things can block water flow and create problems further down the line.

Valleys are not only functional but also beautiful. They create more character for a home than a standard roof does.

3 TYPES OF ROOF VALLEYS

When it comes to roof valleys, there are three main types the roofers build.

1.) CLOSED ROOF VALLEY

A closed roof valley is a popular choice that many homeowners prefer. Not only do closed valleys help you achieve that aesthetic look that many want, but it also is a fairly affordable option.

Closed roof valleys are protected by an ice and water shield used for the underlayment. This acts as a water shield for your roof deck. After the underlayment is installed, shingles are installed to create a closed valley.

2.) OPEN ROOF VALLEY

If you are serious about protecting your home, an open roof valley might be the right choice for you. Open valleys are particularly durable, as they have metal flashing installed on top of the underlayment in order to provide an extra layer of protection.

3.) WOVEN ROOF VALLEY

Woven valleys are similar to closed valleys in the sense that they have the underlayment installed underneath. Where they differ is the shingle installation. In a woven valley, the shingles are installed in such a way that they change the direction of the roof slopes. This allows homeowners to direct the water off the roof in the way they want.

Woven roof valleys are popular with homeowners because they are a very budget-friendly solution.

WAYS TO TAKE CARE OF YOUR ROOF VALLEY

Now that you know the importance of your roof valley, you’ll also understand the importance of caring for it properly! Here are 4 tips to make sure that your roofing system is working efficiently and safely.

1) GET A ROOF INSPECTION

The number one thing homeowners can do to ensure that their roof is up to snuff is to get a professional roof inspection. Roofing contractors will be able to assess your roof for any problem areas and give you advice on how to maintain it and what to watch out for. A proper roof inspection will help you have peace of mind.

2.) MAKE SURE YOU HAVE THE RIGHT MATERIALS

Different climates create different tolls on your roof. While one form of roof valley may be an effective way to protect against rain and snow in one climate, it might not cut it in another. Consulting with a roofing contractor will help ensure that your roof is ready to handle whatever weather is thrown at it. When you have the right roofing materials, you can rest easy, knowing your home is covered.

3.) REMOVE DEBRIS

While valleys are designed to avoid causing debris build-up, they aren’t perfect. Cleaning debris from leaves, twigs, and other items will help you keep your roofing system functioning properly.

4.) DO A SELF-CHECK

Regular checks on your roof can help you catch any problems before they arise. Be sure to check for loose or blown-off tiles, moss growth, or soft, spongy parts of the roof.
