Closed and Open Valleys: The Differences

When talking about your home’s roof, you’ve likely heard your roofer talk about the valleys. There are two kinds of valleys you can consider for your home: closed and open. Regardless of what you choose, both serve the purpose of allowing water to properly run off your roof. But what exactly is it that sets them apart from one another?

Here, the hail damage roof repair experts of Scro’s Roofing Company reveal how closed and open valleys differ from one another.

Closed Valleys

Closed valleys are the most popular type of valley that you’ll see in residential roofing systems, mainly because they’re aesthetically appealing and are fast and easy to install. Apart from that, since they don’t need extra materials to be installed, they’re often considered as cost-effective option compared to open valleys. However, closed valleys don’t shed ice and water as quickly as open valleys do, which could lead to granule loss for your shingles.

To install closed valleys on your home’s roof, simply turn to the storm damage roof repair pros of Scro’s Roofing Company.

Open Valleys

On the other hand, to install an open valley on your roof, a sheet metal will be fastened to your roofing system at its joint. Afterwards, the shingles will be installed on your roof before being cut and sealed at where they overlap the metal. This allows the open valley system to shed ice and water more quickly compared to closed valleys, which minimizes granule loss and allows your roof to have a longer lifespan. If properly installed, this valley can be as aesthetically appealing as closed valleys and is easier to repair.

Keep in mind, however, that open valleys can be a bit costly to install as it will require additional materials to be added to your roof.

We had significant hail damage due to the May 2016 hail storm in Cary, and warded off all the storm chasers that came through our area for 2 months after. I called Scro’s Roofing after the insurance adjusted had written off the roof, and they worked us into their busy schedule. Amazing job done by an amazing and hard-working crew. I was impressed by the way they used tarps to protect the landscaping around the house, and Patricia was pretty particular about cleaning up after the crew. Danny was a pleasure to work with, and he provided several improvements to our roof like a installing a chimney cricket and ridge vents. We used Moire black shingles and the roof looks...

In life you get what you pay for and this is certainly true with Scro’s Roofing. There are so many “fly be night” roofing companies out there who do not have the long standing customer service and support that a local roofing company can offer. Everyone should take the time to educate themselves about the roofing process and the track record of the company, as this is a very larger investment and an area where you don’t want to cut corners. The team at Scro’s Roofing provided me with many educational links and never pressured me into a sale. They wanted to ensure that I fully understood the process and trusted that I would make an intelligent decision. This sharing...

Scro’s Roofing installed a new roof on our home and everything went exactly as planned and scheduled. The installation crew covered all our plants and deck when removing the roof and then cleaned up perfectly when the job was done. We were kept informed all along the job from start to finish so we knew how and when everything would be done. I’ve never experienced a contractor, a company or an owner like Danny who worked with us on every detail. Further, we had gotten several other quotes with Scro’s being the best. This project couldn’t have been done more smoothly… We greatly appreciate Danny the owner and Sarah our scheduling contact. They both were there for all and every...

We just had our roof done by Scro’s Roofing, and we are very happy with the results. Danny and his office were very helpful in answering all of my questions. I did a good bit of research beforehand, and after talking with Danny, I had a lot of confidence that they are up to date on best practices and latest materials. In particular, I liked that they hand nail the shingles, use a synthetic underlayment instead of tar paper, install a drip edge, and provide a 10-year labor warranty. The thing about getting a new roof is that most people may not find out whether the installer did a bad job or used inferior materials for 5-10 years when they...

The big hail storm of May 2, 2016 did extensive damage to our roof (and Leaf-Guard gutters as well). Our insurance company appraised the roof and said it all needed to be replaced. My first choice was again Scro’s Roofing. I was not about to use one of the “storm chasers” that descended on our neighborhood like carpetbaggers from who knows where. Danny, the owner of Scro’s Roofing looked up my record from seven years ago and was able to give me an estimate almost immediately from the information he already had on file. Their estimate was within a couple percent of what our insurance had already written a check which made the decision to go with Scro’s Roofing again...

I had a great experience working with Danny and his team. Danny even recommended a less expensive roofing product based on our needs. Sarah was so helpful and accommodating throughout the process. I wish all home repairs/renovations were this easy and professional. A wonderful company to work with!
