Should you choose an open or closed valley? We like open!
Updated: Apr 21
Have you ever heard of open valley and closed valley roofing systems? If not, don’t worry - you're not alone. Many home owners are unaware of the different types of roof valleys, yet they can have a major impact on the quality and longevity of your roof. In this blog post, we will look at these two different types of valleys, discuss the similarities and differences between them making sure to explain why one might be better suited for your home than the other. By understanding how each methods works and what it entails, you'll be able to make an informed decision that allows you to get the most out of your new or existing rooftop system.
Open Valley- Our favorite!
To create an open valley, your roofer will install a layer of flashing beneath the shingles. This additional element provides visual appeal with its shiny stripe that runs down the center and is revealed through deliberate gaps in overlapping shingles.
Valleys are the water-catchers on rooftops, where rainwater and snow gather before being quickly channelled away. Metal flashing reinforces this role by providing an extra protective layer against intruding moisture while simultaneously aiding rapid runoff - a vital feature for those pesky low pitched roofs! Small wonder that it's such a popular waterproofing choice due to its superior performance capabilities.

Closed Valley Types: Woven and Closed Cut
If you're after a closed roof valley, think twice before committing. Although they can be aesthetically pleasing and provide extra protection against the elements, their performance is often subpar compared to open-style valleys. Excessive expansion and contracting in Florida's harsh climate may speed up the break down process. In some cases we even have restrictions on installing certain types of closed roofs - so it's important to consider all your options!
At Heart Roofing LLC, our team has perfected the art of weaving valleys. Instead of cutting through or leaving gaps in your roof's design, we expertly craft a consistent and timeless look by interlocking shingles from both sides of each valley. Our experienced installers ensure this weave is perfectly smooth while creating an elegant transition between planes - giving you an impeccable finish!
Woven valleys can present a unique challenge due to the shingles that are positioned across the valley. This configuration creates additional opportunities for water intrusion and premature wear of these shingles, particularly on low-slope roofs in more temperate climates where rainfall is frequent. In order to protect against potential leakage, we carefully consider conditions before installing woven valleys.

Closed Cut Valley
For professional performance, open valleys are the preferred choice over closed cut ones. With a closed valley installation, shingles must be manually fitted into the center of the valley and held in place - an intricate process that takes considerable time with no additional benefits for your roof system. Furthermore, these cuts can lead to separation between them which leads to water seeping through rather than being directed away from you home as is intended by any quality roof system.
Woven and open valleys are both a superior choice, for different reasons. But which is best for your specific roof? Reach out to us to discuss your options 321-499-3012
