There are two types of roof overhangs mainly used by people. First, it is eave overhangs, and the next is rake overhangs. Both of which are used in abundance, but aside from those two, you can still meet various overhangs, including those designed specifically for doors when space is limited, despite being used only for specific needs.
Different Types of Roof Overhangs
Simply put, overhangs are defined as the roof extension beyond the exterior wall. Typically, overhangs protect the house, including those with flat roofs, from excessive sunlight during the hottest moments of the day or summer.
Overhangs are especially crucial for flat roofs to prevent water damage as they don’t naturally shed water as effectively as sloped roofs.
Aside from that, overhangs are also used to protect the house from rains that may ‘smack’ the siding, door, or windows, thereby reducing the risk of water damage. They are essential in safeguarding the sides of a home from the elements. Although it cannot protect it whole, the effect is minimized.
The difference between each type of overhang can be seen below.
- Eave overhangs
Eaves are the type of overhangs placed at the edge of the downslope of a roof (typically on a pitched roof). Since it is placed at the lower edge of a roof, this kind of overhang follows the size of the roof length.
- Rake overhangs
Rake overhangs are mainly found only in a gable roof. It is an overhang that can easily be found on the face side of the gable roof. Given it is located on the ‘face’ of a gable roof, you can say that the shape of rake overhangs is often triangular.

What is the difference?
Both are overhangs, but the benefits are pretty different. In eave overhangs, it is often used in the side of a house. Therefore, it is often used to protect the door, wall side, and windows from the sun strike, wind, rains, and snow, providing essential shade for windows to reduce heat during summer.
Given this function, the size of eave overhangs is typically wider than the rake counterpart, often extending up to 24 inches to allow for adequate shade for windows to reduce heat and protect against water and snow.
Even so, the making of eave overhangs, including cantilever roof overhangs, should not be conducted thoughtlessly. These overhangs can extend up to 24 inches or more, providing significant protection and aesthetic appeal.

It is said that the wider the eaves are, the more you need to support the soffit from beneath. That will require you more work to do and more money to spend.
On the contrary, rake overhangs don’t take many roles in protecting the house from rain, sun, etc. Why so? This is because the overhang isn’t that wide. Plus, typically, the face size of a gable doesn’t have a window, door, or anything, especially if the gable is on the backside of the house.
Even so, it doesn’t mean these two are the only types of roof overhangs. Awnings, retractable awnings, canopy, and pergola can also be included in a set of overhangs—despite these being not in one entity with the roof itself.
Using these roof overhangs on houses depends on how badly you need it. It is good to purchase any of these overhangs and include them in your house, especially in cases where different building elements meet without proper construction and waterproofing. Otherwise, it can ruin your house by adding things to maintain. Plus, it takes space, too.
So, that sums up the information about types of roof overhangs. Not only do they protect against weather elements, but overhangs also play a crucial role in allowing fresh air to circulate around the home, enhancing indoor air quality.
