5 Advantages of a Slant Roof Shed for Your Shed

5 Advantages of a Slant Roof Shed

A slant roof shed is a popular choice for those looking to add extra storage space to their backyard. Unlike a traditional flat roof shed, a slant roof shed has a distinctive look that can add character to any outdoor space. But, beyond its aesthetic appeal, there are several advantages to choosing a slant roof shed for your shed.

The 5 main advantages of a slant shed roof are good drainage, higher headroom, more light, more efficient and pleasing to look at.

5 Advantages of a Slant Roof Shed for Your Shed

Let’s take a look at each:

Improved Drainage… One of the biggest advantages of a slant roof shed is improved drainage. The slanted roof allows rainwater and snowmelt to run off the roof quickly and efficiently, reducing the risk of water damage and leaks. This is especially important if you live in an area with heavy rainfall or snowfall. With a slant roof shed, you can rest assured that your stored items will remain dry and protected.

Increased Headroom… Another advantage of a slant roof shed is increased headroom. With a slanted roof, the height of the walls can be increased, giving you more room to move around and store your items. This is especially useful if you plan on using your shed as a workspace or hobby area, as it provides enough room to stand up straight and work comfortably.

Better Light… A slant roof shed also provides better natural light compared to a flat roof shed. This is because the slanted roof allows more light to enter the shed, making it easier to see what you’re working on or looking for. This is especially helpful if you plan on using your shed as a workspace or hobby area, as you won’t have to rely solely on artificial light to get your work done.

Energy Efficiency… A slant roof shed can also provide energy efficiency benefits. With a slanted roof, you have the option of adding insulation to your shed to help keep it warm in the winter and cool in the summer. This can help you save money on energy costs and make your shed a more comfortable place to work or store your items.

Aesthetically Pleasing… Finally, a slant roof shed is aesthetically pleasing and can add character to your backyard. With its unique look, a slant roof shed can complement the design of your home and provide a focal point for your outdoor space. Whether you choose a traditional or contemporary design, a slant roof shed is sure to add style and interest to your property.

What is the Lowest Slope for a Slanted Shed Roof?

The minimum slope, or pitch, for a shed roof is typically considered to be 2/12, which means that the roof rises 2 inches for every 12 inches of horizontal run. This type of slope is often referred to as a “gentle” slope and is sufficient for shedding rainwater and snow. However, the minimum slope required for a shed roof can vary depending on local building codes and climate conditions.

For example, in areas with heavy snowfall, a steeper roof pitch may be required to prevent snow from building up and causing structural damage. It is important to check with local building authorities to determine the minimum slope required in your area.

How to Build a Slanted Roof on a Shed?

Building a slanted roof for a shed involves the following steps:

Determine the Pitch… Decide on the slope of the roof and determine the rise and run (the height and length of the roof, respectively). This will help you calculate the length of the rafters you need.

Gather Materials… You’ll need lumber for the rafters, plywood for the roof decking, and roofing materials such as shingles or metal panels. You’ll also need roofing underlayment, nails, and roofing adhesive.

Frame the Roof… Start by installing ridge and collar ties at the peak of the roof. Then, cut and install the rafters along the sides of the shed. Make sure to space them evenly and secure them to the ridge and collar ties.

Install the Roof Decking… Nail or screw the plywood to the rafters to create the roof deck. Make sure the seams between the sheets of plywood are offset to provide added strength.

Install the Underlayment… Roll out the roofing underlayment and secure it to the roof deck with roofing adhesive and nails.

Install the Roofing Material… Install the shingles or metal panels according to the manufacturer’s instructions. Make sure to overlap the edges of the panels to provide a water-tight seal.

Finish the Roof… Install the trim around the edge of the roof and caulk any gaps. This will prevent water from penetrating the roof.

You may also want to have a good overhang on your roof to help keep water away from your shed’s foundation, Check out my article How Much Roof Overhang Should a Shed Have? for more information.

What are the Disadvantages of a Slanted Shed Roof?

A slanted roof for a shed has a few disadvantages, including:

Cost… Building a slanted roof is generally more expensive than a flat roof because it requires more materials, such as longer rafters, and more complicated framing.

Space Limitations… The slanted roof reduces the headroom in the shed, which can make it difficult to stand up or store tall items.

Complexity… Building a slanted roof is more complex than building a flat roof and requires a certain level of carpentry skill and experience.

Maintenance… A slanted roof is more susceptible to leaks and damage from high winds and heavy snow than a flat roof. This means it will require more maintenance over time, such as replacing damaged shingles or repairing leaks.

Design limitations… A slanted roof can limit the design options for the shed, as it may not fit with certain architectural styles or be suitable for certain types of buildings. There are many types of roofs you can use, check out my article The 7 Most Popular & Practical Shed Roof Designs to see if one of these types will be a better option for your shed.

How Do You Cut Rafters for a Slanted Roof?

Cutting rafters for a slanted roof requires a certain level of precision and accuracy, as the angles must be exact to ensure the roof structure is strong and secure. Here’s how to cut rafters for a slanted roof:

Determine the Pitch of the Roof… The pitch of the roof is the ratio of the rise (height) of the roof to the span (horizontal distance). For example, if the roof rises 6 inches for every 12 inches of span, the pitch would be 6/12 or 1/2.

Calculate the Length of the Rafters… To determine the length of the rafters, use the Pythagorean theorem, which states that the square of the hypotenuse (the longest side) of a right triangle is equal to the sum of the squares of the other two sides.

Cut the Birdsmouth… The birdsmouth is a notch cut into the bottom of the rafter that allows it to sit securely on the wall plate. To make the birdsmouth, mark the height of the plate on the rafter, then make a square cut on the end of the rafter.

Cut the Plumb Cut… The plumb cut is the angled cut at the top of the rafter that forms the slope of the roof. The angle of the plumb cut will be determined by the pitch of the roof. To make the plumb cut, use a framing square to mark the angle, then make the cut with a saw.

Repeat for Each Rafter… Repeat the above steps for each rafter, ensuring that each rafter is exactly the same length and angle as the others to ensure a uniform and level roof.
