Roof Slope

The slope of your roof is an important factor to consider for both its form and function. A roof with a steep slope will allow water from rain or snow to run off more quickly. The slope of your roof is typically communicated as a ratio in relation to the roof’s proportions.


A roof with a steeper slope will allow water from rain or snow to run off more quickly. The slope of your roof is typically communicated as a ratio in relation to the roof’s proportions. The slope of your roof can be important in determining how quickly water will run off of it. Roofing contractors typically communicate the slope of a roof as a ratio, such as 6:12, meaning that for every 12 inches horizontally, the roof rises 6 inches vertically. For example, a roof with a 4 in 12 slope will rise four inches vertically and 12 inches horizontally. A steeper slope is generally better because it allows water to run off more quickly.


From flat grades to steep inclines, a better and more interesting silhouette can be created by appropriate roof slope.


As you explore the range of building materials, you should keep in mind the impact that the slope of your roof has on the aesthetics of your home’s exterior.


Many roofers can leave these calculations to their roofing contractor, but it is important for owners to be aware that the International Residential Code has specific minimum slope requirements for all roofing coverings, including asphalt roofing shingles. Your roofer can help you find the right choice for your slope.


Although some roofs are built with certain slopes and types of slopes, it’s not a hard and fast rule.


8 Common Roof Types


Gable Roof


When you think back to your first crayon drawing of a home, you must always remember that it was a picture of a home sitting on a flat roof. It was a simple, rectangular flat roof. If you were to draw the shape of a gable roof today.

The gable is the most widely adopted roof style and is a popular choice for more traditional homes as well. However, it can be used on a variety of home designs as well, such as over entryways, and is also a popular choice for homes with garages.


Clipped Gable Roof


It is designed to meet a basic roof shape and measure in height and width with the two ends of the roof meeting a ridge, but then borrows an element from hip roofs: the top peaks are bent in, creating a V-shape instead of a horizontal ridge. This roof style is ideal for keeping a roofline low and adding interest to a home.

These hips provide an interesting architectural detail to homes and help showcase the performance, design and commitment of high-performance, designer shingles.

Dutch Gable Roof


The Dutch gable roof is a hybrid roof type that uses design features from both gable and hip roofs. A small gable roof, known as a “gablet”, is set on top of a regular hip roof.

Having a gable portion on a home is a great asset to homeowners. It provides them with more attic space and, if they choose, they can install windows to let in more natural light.

Gambrel Roof


Having a gambrel roof on your home has many benefits. The design of the roof allows for the use of the upper floor as an attic or loft. Additionally, adding windows to the sides of the roof can bring in natural light and make the upper story more livable.

When deciding whether or not a gambrel roof is right for your home, there are many factors to consider. The most important of these may be the steepness of the roof. Because gambrel roofs are so visible, it is essential that homeowners take care in choosing the right roofing shingles for their home.


Hip Roof


A traditional hip roof has four slopes that are all the same length and meet to form a ridge. However, there are variations of hip roofs, such as a half-hip, that has two shorter sides with eaves.

When looking at your house from the street, most of the roof is likely visible since hip roofs have four slopes that are all the same length. This means that the type and color of roofing shingles you choose will play a big role in your home’s overall exterior look.


Mansard Roof


The mansard roof gets its name and its classical shape from French architecture. This design is characterized by its four-sided shape with double slopes. The lower slopes of the mansard roof are very steep, and they can be either flat or curved. This type of roof was very popular during the French Renaissance, and it was often used in the construction of public buildings and mansions. The mansard roof became even more popular during the Second Empire of France, when it was used extensively in the construction of apartment buildings.

The mansard roof became a popular choice for homeowners in the United States after it was first introduced in France. The style allows for extra attic space and multiple windows, which makes it ideal for homeowners who want to make full use of their upper story. Dormers can also be added to the mansard roof style to give it a more appealing look.

Shed Roof


The shed roof, also known as a “lean-to”, is a popular roof style for modern home designs. This roof style resembles half of a traditional gable. The shed roof has been used for porches and additions for many years, but is now being used as the primary roof style for ultra-modern builds. The shed roof is a popular choice for modern homeowners who want a sleek and stylish look for their home. When building a shed, most people choose to have a roof with a lower slope. The most common slope is 4 in 12 or less, but a steeper slope will make water runoff happen more quickly.

Flat Roof (Low Slope Roof)


When most people think of flat roofs, strip malls and industrial complexes often come to mind. However, during the period between 1945 and 1970, many mid-century modern architects experimented with flat rooflines creating dream homes for movie stars and wealthy businessmen. Flat roofs matched the look of the period, blending with the environment and providing large open floor plans. Some homes feature a limited flat surface area with the rest of the roof having a gable or hip design.  Additionally, some home additions may use a flat roof to provide extra second floor living space.

Keep in mind flat doesn’t really mean flat —there needs to be some incline to allow for water drainage.


Pro Tip: Flat roofs (low-slope) are particularly vulnerable to leaks, so they must be thoroughly waterproofed and topped with an appropriate material, such as a self-adhered, multi-ply, SBS modified bitumen membrane system, a PVC, TPO or rubber membrane.
