There are essentially two categories of roofs: flat and sloping. As the name implies, a sloped roof is any roof installation that is constructed at an angle rather than being flat.
Sloped roofs are the more common roof type for residential properties, as they are multi-functional and aesthetically pleasing. They are also weather-resistant, requiring less maintenance. These roofs naturally shed water and snow, protecting the home’s structure.
A sloped roof is a roof with a pitch of more than 10 degrees. The terms "slope" and "pitch" are often used interchangeably, but both refer to the angle of the roof.
Roof pitch indicates how many inches the roof rises for every 12 inches in depth. This measurement helps dictate water drainage, roof material limits, attic space, and more. Geographic location also plays a role in determining roof pitch, as sloped roofs are especially important in areas with heavy snow or rain.
There are different types of sloped roofs, each categorized by their pitch and overall geometric shape. Learn more about each type below.
A gable roof has two sloping sides that meet at a central ridge. This creates a triangular “A” shape, making this roof ideal for shedding water and snow. This roof type is also incredibly cost-effective. There are several specialized variations of gable roofs as well.
A hip, or hipped, roof is a sloped roof where all sides slope downward toward the walls. This eliminates vertical gable ends and offers extra wind resistance and structural stability. This roof type is a great choice for homeowners in hurricane-prone areas.
These "barn-style" or French-style sloped roofs provide extra living space. Gambrel roofs have slopes on only two sides, while mansard roofs have slopes on all four sides. Mansard roofs are more complex and expensive to build. Both are efficient for maximizing attic space, but not ideal for heavy snowfall areas.
Shed, or monopitch, roofs have a single, uninterrupted sloping surface. These modern, single-slope designs are often used for tiny homes because they require fewer materials and are cheap and easy to build. These roofs shed rain and snow effectively, but can sometimes be vulnerable to wind.
When choosing a sloped roof, you’ll want to consider different roofing materials. Typically, the degree of the slope will dictate which materials can be used. Here are some options:
Working with a professional roofing company will help make these decisions easy. Hoffman Weber’s team will walk you through each step of the process to ensure you’re making the right choices for the longevity and safety of your home.
Sloped roofs do a great job of withstanding the elements, especially by shedding water and snow effectively. However, they still require an inspection every 1-2 years. This is especially important after severe weather events.
This will help you avoid larger issues. Regular inspections and maintenance are important for preventing ice dams, prepping for winter, and generally avoiding larger, more costly issues.
Choosing the right slope is critical. Not only should you consider geographic location and building type, but you’ll also need to consider architectural harmony and adherence to local building codes.
That’s why it’s so important to work with a roofing expert. Hoffman Weber has decades of experience guiding homeowners through the roof selection process. Our team is well equipped to answer your questions and help you make the right choice. Check out our virtual designer to get started.
While these terms are often used interchangeably, they represent different mathematical values. Slope is the ratio of vertical rise to horizontal run. This is portrayed as a ratio of inches per foot (ex., 4:12). Pitch is the total vertical rise over the total horizontal span of the building, expressed as a fraction.
4:12 and 6:12 are the most standard roof pitches for residential homes.
You can use asphalt shingles on a low-slope roof only if the roof slope is at least 2:12. Special underlayment and installation techniques may be required for slopes under 4:12.
The angle of sloped roofs allows snow to slide off naturally. This prevents snow buildup and reduces the risk of ice dams.
The lifespan of a sloped roof depends heavily on the roofing material and the geographic location. On average, sloped roofs with asphalt shingles last between 15 and 30 years, while metal roofing options last 40 to 70 years. Other materials like tile or slate may last even longer.
