You may not know what a skillion roof is just by its name, but you probably know what it looks like. Skillion roofs have a single flat surface with a steep pitch toward one side, almost like a ramp. These roof designs started as a popular choice for shed construction, but more and more homeowners are choosing skillion roofs for their homes because of their sleek and minimalist look.
If you’re unsure about the benefits that skillion roof structures have for your home, we can help. Read on to learn more about the various types of skillion roofs, their benefits, and what to consider before you choose one for your home.
What Is a Skillion Roof?
Unlike traditional gable roofs, which have two sloping sides that meet at a peak, skillion roofs only have one sloping side that runs from one side of the building to the other. Many people call them “shed roofs” because they’re common on sheds and other types of outdoor structures.
Skillion Roof Styles
If you want to add a skillion roof to your home, there’s more than just one style to pick from. Skillion roofs come in several variations, so it’s important to weigh the options before you make a choice.
Standard Skillion
The standard skillion roof is the most common type. It features a single flat surface that slopes from one side to the other, with one end higher than the opposite end. This simple design is ideal for smaller homes, and its straightforward configuration makes it cost-effective.
Split Skillion
A split skillion roof has two separate sections at different heights. These sections typically meet at a vertical wall somewhere over the middle of the house. The roof planes may slope in opposite directions or, occasionally, in the same direction.
When sloping in opposite directions, the split skillion can resemble a traditional gable roof but with an offset peak. This design can add a dramatic flair to a building, but it’s more complicated to install than a standard skillion.
Multiple Skillion
For larger structures, a multiple skillion roof uses several sections, usually three to five, at varying heights and sizes. This style can create interesting visual patterns and it allows for more flexibility in interior space design, much like a jerkinhead roof design. However, its complexity may be overkill for most homes.
Butterfly (Double Skillion)
This V-shaped roof has two sides that slope steeply downward to form a central valley. It’s effective for collecting rainwater and can stand up well to high winds, but it’s more expensive to install than other skillion styles. However, if you have money to spare, its striking appearance can give your home a modern, sophisticated look.
Advantages of Skillion Roofs
In addition to their unique look, skillion roofs have a handful of benefits for homeowners. If you’re on the fence about installing one, the factors below may change your mind.
Skillion roofs typically require less material than more complex roof designs. Their simple structure also makes them quicker and easier to build, which can translate to lower labor costs. Skillion roofs can save you money and reduce the overall timeline of your building project, making them a solid option for budget-conscious homeowners.
With their steep slope, skillion roofs provide better drainage than flat roofs, reducing the risk of water pooling and potential leaks. Better water runoff can also help prolong the roof’s life, meaning that you’ll spend less on repairs over time. If you live in an area with high rainfall, this is an especially helpful benefit.
Skillion roofs allow for a range of slopes, from a steep 9/12 to a flatter 3/12 pitch. This flexibility allows homeowners to get creative with their designs. Long, flatter pitches provide plenty of space for skylights or solar panels, while steeper pitches add more of an external flair.
By orienting the house with the low side of the roof facing the street or neighboring properties, homeowners can limit the view into their homes, affording them better privacy. It can also lead to a greater sense of security and comfort, making your home feel like a private oasis instead of feeling claustrophobic in a crowded neighborhood.
Considerations for Skillion Roof Installation
Before you call a contractor and have them install a skillion roof, you need to consider a few factors that can make or break your construction. Depending on what pitch you choose, it could affect what roofing materials you need to use. For low-pitched roofs (3/12 to 4/12), you should use standing seam metal or rubber roofing. Only use asphalt shingles or clay tiles if you have a steeper pitch of at least 4/12 (unless you already installed a special underlayment).
Like gable roofs, skillion roofs can be vulnerable to wind damage. For areas prone to strong storms, a multiple skillion design may be a better option for wind resistance. You can also use reinforcements like hurricane straps and bracing for better durability in extreme weather conditions. Due to their sloped design, skillion roofs don’t allow for a traditional attic. However, homeowners can still maximize overhead space by incorporating a partial loft or vaulted ceilings into their design.
Skillion roofs typically require box gutters, which are wider and stronger than standard gutters to handle the concentrated water flow from the single-slope design. While they’re very effective, you’ll probably need to clean them more frequently to prevent clogs. Without proper maintenance, you could end up with drainage problems and water-related issues.
Final Thoughts About Skillion Roofs
Skillion roofs may have started as a simple solution to shed roofing, but their straightforward design and bold look make them perfect for modern home construction. However, don’t jump the gun and make plans to install a skillion roof without talking to a contractor first. When in doubt, find a roofing contractor and get their advice before you make any decisions.
