How Much of a Roof Overhang on Shed?

When it comes to building a shed, one crucial detail often overlooked is how much roof overhang on shed is necessary.

At Homestead Supplier, our years of experience have taught us that the right overhang enhances the shed's functionality by directing runoff away from the walls and adds an aesthetic touch that elevates the overall design. In general, a roof overhang should be 12”-18” for eaves and 8” for rakes.

This article dives into the essentials of the roof overhang, providing you with the knowledge to make informed decisions for your shed project, ensuring it meets both practical needs and design aspirations. 

How Much of a Roof Overhang Should You Have on a Shed?

The ideal overhang for your shed's roof can vary, but you're usually looking at between 12” and 18” for eaves, and 8” for rakes. It's all about striking the right balance.

Mastering this balance is key when learning how to roof a shed or how to roof a shed with roll roofing.

According to our research and hands-on testing, the main purpose of an overhang is to ensure that runoff from the roof has ample space to fall to the ground, preventing it from causing moisture damage by running down the walls. It's like giving your shed a little umbrella to keep it dry and cozy.

But that's not all. An overhang also serves as a protective shield for the base of your shed, adds an extra layer of defense against window leaks, and can even provide a cozy shelter when you're fumbling with the lock in the pouring rain or seeking shade in the summer heat.

And let's not forget the aesthetic aspect – a well-designed overhang adds character and depth, enhancing your shed's curb appeal and blending it seamlessly into your outdoor space.

Now, when it comes to specifics, the ideal overhang size and shape depend on a few factors: the use and look of your shed, the climate, and whether your roof is flat or peaked. For flat roofs, the overhang extends straight out, while pitched or gable roofs have overhangs that slant downward.

The key is to consider your needs and the particular uses of your shed, ensuring that the overhang serves its purpose without compromising the structure or appearance.


The significance of the roof overhang on a shed extends far beyond mere aesthetics; it plays a pivotal role in protecting the structure from moisture damage, enhancing its longevity, and providing functional benefits like shelter and shade.

By carefully considering the size and shape of the overhang in relation to your shed's design and the local climate, you can ensure a perfect blend of form and function. Whether you're looking to safeguard your shed or simply add a touch of architectural interest, the right overhang can make all the difference.
