12 Most Common Roof Types Compared (Pros & Cons)

If you’re facing a new construction of a home, roof, or addition to your existing home, you’re going to have many decisions to make regarding materials, design, budget, etc. What might be surprising is one of the most important decisions is the roof type! Not only will this play a huge role in the overall style of your home, but it will also affect the function and performance of your home against the elements. With so many factors to consider, we’re going to help you by listing out some pros and cons of roof styles and what kind of homes they are best suited for. Gable Roofs A gable roof is what you imagine when you think of a typical house—square sides with a triangle-shaped roof. Gable roofs are incredibly common amongst many different styles and types of homes. They’re super versatile, and their simple design makes it easy to install and work well to keep your home free of standing water and sheds snow and ice. Pros of Gable Roofs Cons of Gable Roofs Dutch Gable Roofs There are many different variations of gable roofs, and we want to cover them all because despite having a similar base component, they can be vastly different and offer even more functionality. The dutch gable roof, for example, combines elements of a simple gable design plus a hip roof on the front. So they can work great for attic spaces on your home or garage and have room to add additional windows for more light. Pros of Dutch Gable Roofs Cons of Dutch Gable Roofs Clipped Gable Roofs A clipped gable roof goes by many names such as bullnose or jerkinhead. It’s called a clipped gable roof because it looks like some clipped off the ends of a basic gable roof, creating a small angle at each corner of the roof. A hip roof has a much bigger “hip” at the end of the roof, but a clipped gable roof will have one much smaller. Pros of Clipped Gable Roofs Cons of Clipped Gable Roofs Gambrel A gambrel roof is more often than not used on barns or small sheds. There are four surfaces to this roof, starting with a pitched low slope on top, which then bends down in two panels that run the rest of the way down the side of the house. It looks a bit like half an octagon shape. This four-sided design allows for a wider area and makes more head space because the pitch is a little lower and not so steep on the edges. For this reason, this roof works perfectly for barns with upper-level lofts to hold stacked hay. Pros of Gambrel Roofs Cons of Gambrel Roofs Flat Roof What is more often used in commercial structures like apartment buildings, malls, and office buildings, became widely used on mid-century modern residential homes in the 50s and 60s. It’s important to note that a flat roof is not officially flat—they must have a slight slope of at least 2% to allow for water and snow run-off. Otherwise, you’d just have sitting water that can cause leaks and cave-ins. Pros of Flat Roofs Cons of Flat Roofs Shed A shed roof is kind of like a flat roof, but it’s at a much steeper incline. With just a single slope, you will commonly find shed roofs utilized on cabins, barns, and of course, sheds. The high-pitch slope is very simple but perfectly effective for water and snow shed. Pros of Shed Roofs Cons of Shed Roofs Hip Roofs A hip roof is made up of 4 equal sloped sides that converge to a ridge in the middle. It’s almost like a pyramid, but not quite. Two sides will meet to form a small flat ridge, while the other two come to a point where it meets the ridge. Hip roofs will have a much slighter slope than other styles, and the majority of your roof’s surface will be visible looking at your home. The increased visibility means it’s essential to pick a roofing color and material that you enjoy as it makes up a large part of your home’s curb appeal. Pros of Hip Roofs Cons of Hip Roofs Mansard Roofs Mansard roofs originated in French architecture but have been adopted in America for those wanting extra attic space and room to install Dormer windows on their upper floors. It also has four sides, but then an additional slope and four sides on top, as the picture demonstrates. The sides may be a straight angle or be curved outwards for a unique design.  Pros of Mansard Roofs Cons of Mansard Roofs Hexagonal Roofs You are most likely going to find a hexagonal roof on an outdoor gazebo. The hexagonal roof’s shape is an eight-sided roof, where all sides meet at a single point on the top.  Pros of Hexagonal Roofs Cons of Hexagonal Roofs Saltbox A saltbox roof is similar to a gable roof as it has two sides with open ends that meet in the middle. However, one side is generally much longer than the other, and it’s also often positioned to have the open ends of the sides of your homes rather than a peak from the front view. They’ve proven very effective in climates that get snow because of their lack of flat spots and high pitch; they allow snow and ice to shed easily.  Pros of Saltbox Roofs Cons of Saltbox Roofs Dormer Roof Dormer roofs are more often called Dormer windows, as they are windows added to a Mansard style house that jut outward like a small room or extension of the upper attic living space. They allow for more natural light and ventilation into the space.  Pros of Dormer Roofs Cons of Dormer Roofs Butterfly Butterfly roofs get their name from, you guessed it, butterflies. The roof is shaped like their wings because rather than point up in the center to meet at the ridge, they point downwards in a V-shape and meet in a valley in the center.  Pros of Butterfly Roofs Cons of Butterfly Roofs

Roof Types and the importance within Design

We all know that roofs are an integral part of a house and probably one of the most important elements.  Roofs keep us dry from the rain and snow, shade us from the sweltering sun and block us from the unyielding wind.  Usually roof forms are dictated by technical, economic and aesthetic considerations. Did you know that there are more than a dozen basic roof types and even more combinations of those?  I’m just going to touch on a few of the more popular basic forms for homes: Flat:  Flat roofs are just that, flat.  They are typically used where the climate is arid and drainage is of secondary importance. They are a very popular roof type for warehouses, commercial spaces, office buildings and often residential structures. Shed:  This is the first category of many sloped roof types that I will be discussing. The shed, sometimes referred to as “lean to” or “mono-pitched” contains only one pitch.  You can think of it as a flat roof that has been tilted slightly.  It is often used on just a portion of a home.  The shed roof is usually used in combination with other roof forms to create a home with interesting rooflines. Gable:  A roof with two slopes that form an “A” or triangle is called a gable roof. This type of roof is very common on North American homes.  The gable roof can contain roof pitches that are very shallow to ones that are extremely steep.  Also, numerous gable roofs can be placed together at perpendicular angles to cover a home with many wings. Clerestory:  A clerestory roof is one that combines both a gable and shed roof.  A clerestory usually contains a higher gable roof that sits atop a short wall with a shed roof below.  This allows for windows to be placed within the short wall for light within the interior of a large space. Hip:  A roof that starts with a gable shape but has a sloped end instead of a vertical wall is called a hipped roof.  The hipped roof slopes upward from all four sides of a structure, having no vertical ends. This type of roof is very common in residential designs. Gambrel:  A gambrel roof is a type of gable roof with two slopes on each side, the upper being less steep than the lower. This roof form is very common in barn designs. Mansard: This type of roof is a hipped gambrel roof, thus having two slopes on every side. It can provide extra attic space or other rooms without having to build an entire additional floor. Pyramid: As the name suggests, this type of roof is shaped like a pyramid.  This kind of roof is usually on a small portion of a house or on small structures such as a garage or pool house. So there you have it, the basic roof types of residential construction.  To design a visually stimulating house, a few different roof types may be used together or several of the same forms may be utilized in different ways.  This creates a home that uniquely responds to both its interior function and its exterior individuality.
