Benefits Of Roof Overhang On Sheds

How to Extend or Add a Roof Overhang to Building Remodeling Tips

While shed overhangs may seem forgettable, they have many important benefits that protect your shed and improve its aesthetics.

Overhangs also provide protection from the elements by shielding windows, walls, and doors from rain, while at the same time directing water away from your sheds foundation.

As with a front porch on your home, an overhang on your shed roof is a convenient feature when its raining and youre trying to unlock your sheds door.

Shed overhangs also help to regulate the temperature inside the shed by blocking sunlight from shining directly through windows in the summertime when the sun is higher in the sky. During the winter, when the sun is lower in the sky, overhangs allow the sun to shine through the windows to warm the shed.

Sheds with large overhangs can also provide additional storage space for equipment. The space under a shed overhang is a dry place to stack firewood or lean your wheelbarrow.

There are also aesthetic benefits to roof overhangs. Like it or not, a shed will be a significant feature in your yard. You want that feature to add to the appearance of your property, not detract from it. Overhangs add character and help your shed avoid that boxy flat look.

How To Build An Overhang On A Shed

How to Extend or Add a Roof Overhang to Building ...

While it may seem like a complicated task, building a shed with overhang doesnt require much more additional effort than building a conventional roof. And while it may cost you a little more in material, the benefits, as I discussed above, are more than worth it.

How big to make the overhang depends on what you need it for. A shed with an 8-foot eave height would benefit from an overhang of just 6. This will protect the tops of windows and door openings from moisture while directing water away from the foundation.

Larger overhangs can help to keep you dry while standing at the sheds doorway and prevent the sun from heating your shed. Overhangs can vary from a few inches to a few feet depending on preference however, the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes. That said, overhangs can extend as far as 2 without the need for external supports.

The size of the roof overhang you choose depends largely on the style of your sheds roof.

With a flat shed roof, the roof simply extends past the wall plate to provide an overhang. Because this style of a shed has a flat roof, it can facilitate a wider overhang, which is ideal for storage.

For slanted roof sheds, overhangs add character and facilitate proper drainage. Due to the sheds design, a significant amount of rain runs off the rear of the shed. An overhang helps direct water away from the foundation on the sheds low side.

How To Build An Eave Overhang

Building an eave overhang on most shed roofs is a relatively simple task. The process involves extending the rafters beyond each wall, creating what is known as rafter tails. Rafter tails are the part of each rafter that juts beyond the wall.

Rather than go through the complicated process of calculating just how long you need to make each rafter to achieve the overhang size you want and the angle of each cut, its easier to install the rafters with plenty of extra lengths then cut to size.

After the rafters are installed, mark off the desired length. Use a plumb bob to snap a straight chalk line, then cut using a circular saw. If you prefer a square end to your eaves, use a quick square to mark your line.

Once youve cut one rafter, create a jig by holding a piece of plywood against the wall of the shed and the rafter.

Trace a line around the top and face of the rafter tail and the wall of the shed. Then cut the plywood piece on the lines using a circular saw or table saw. You now have a jig you can use to mark cut lines for the remainder of your rafters.

If youre using trusses to build your shed, then make sure to design your truss so that the top chords extend far enough outward to create the desired overhang.

Also, be sure to raise the heel of your truss design, which will increase the distance between the top chords and bottom chord, making the roof taller. This will ensure that your overhang does not interfere with windows or doors.

The Benefits Of Adding A Roof Overhang System

Adequate roof overhangs help shade windows in hot weather and reduce the amount of rain that hits your siding, windows, and doors. Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. The siding underneath the overhang is known as the soffit. Overhangs are common in most house designs, providing protection against both wind and rain. The length of the overhang depends primarily on the climate. The longest overhangs are seen in the wettest climates.

Many residential designers pay too little attention to roof overhangs. Roof overhangs have several important functions: they can protect exterior doors, windows, and siding from rain they can shade windows when solar heat gain is undesirable and they can help keep basements and crawl spaces dry. A house with improper overhangs can overheat in the summer, can suffer from water entry problems at windows and doors, and can have premature siding rot.

Does your house have a roof overhang? If it does not, you might realize your need for one if you have experienced water in your basement or crawl space. One function of a roof overhang is directing water away from the foundation. A high-quality gutter system is necessary for this as well, but roof overhangs greatly increase a roofs productivity in this area. A roof overhang also protects the upper portion of your exterior walls that it is attached to from rainfall. In addition, it shades the windows under it from the sun.

For extensions that are more than 10 inches, additional rafters will need to be installed. Without additional rafters, the extra weight of the added materials will not be supported. The contractor will first remove drywall and shingles before securing the new rafters to the existing ones.

What Are The Advantages Of A Roof Overhang

An Alternative Way to Install Roof Overhangs

The main advantage is having the water run off from the roof fall away from the sheds walls and foundation especially if youre not planning on using any type of guttering system to direct water away from the structure. In those regions where there is a lot of rain, youll shed the use of overhangs.

Another advantage is it allows for the installation of a vented soffit which lets air enter the roof cavity and exit thru the ridge venting preventing moisture from building up inside of the attic causing mold and rot.

The overhang vented soffit also prevents birds and other small animals from getting into the attic space and building nests. A screened vent is also used to prevent small insects like bees, wasps and other flying bugs from getting into the attic area.

The roof overhang is also part of a good design and makes the shed look more like the house. It also keeps rain from getting into doors, windows and helps keep wood siding from needing extra staining or painting. I use the overhang on my shed to protect some of my tools from the rain and its also a good place to stack some firewood for the winter.
