One of the most significant parts of any home is its roof. If you are planning a new build or a significant roof remodeling or replacement project, you’ll want to know a little bit about the various types of roofs as well as the pros and cons of each. Below is some information that will be very helpful to you during the planning stage.
Different Types of Roofs
There are dozens of roof types, but the styles discussed in this article represent the most common ones used on residential housing or other buildings.
We recommend talking to a professional roofer if you want to get expert advice and ask questions about your roofing project. Usually these trusted contractors have completed numerous projects and can help you immensely before making any final decisions.
So let’s start with the various roof types:

- Which Roof Type is Best?
A gable roof is perhaps the most common and consists of two slopes that meet at a common ridge at the top to form an upside down “v”. Gable roofs are often placed on ranch or cottage style homes as well as on modular housing.
- Provide more overhead space inside attics
- Their simple design makes them very inexpensive to build
- Shed water easily to prevent leaks from occurring
- More susceptible than other roof types to wind damage
- Require additional vents for proper ventilation
- May not be as aesthetically pleasing on historic or vintage-style homes
A gambrel roof often appears on barns and farm houses. It contains two different slopes, with the lower one being steeper than the other one. Gambrel roofs are slightly rounded at the top, and often appear as though they are “capping” a building.
- Provides more space in the loft, making it ideal for buildings with an upper apartment
- Requires fewer building materials than other roof types
- Inexpensive to construct and maintain
- Cannot handle heavy snowfall, and may collapse under the weight
- Require a great deal of maintenance to keep them in shape
- Poorly constructed gambrel roofs have a tendency to leak
Flat roofs are those without an obvious pitch. Although they appear flat, they nonetheless have a very slight pitch to allow water to run off. Flat roofs are often used on commercial buildings such as retail outlets, but are common on mobile homes as well. Moreover, they are also found in some European countries as residential houses.
- Provides space for an outdoor garden or patio
- HVAC units can be placed on top of the roof to keep them well hidden
- Makes adding solar panels very convenient
- Highly susceptible to leaks as water may often pool on top of them
- Require ongoing maintenance, which can be expensive to keep up with
- Frequent inspections are needed to detect leaks and repair them before major damage occurs
A hip roof is one that contains a slope on all four sides that meets at a common ridge at the top. Think of a hip roof as being two separate gable roofs on a single structure. Hip roofs are often found on homes with wraparound porches, as well as traditional farmhouses and multi-story structures.
- Very stable, making them perfect for high wind areas
- Snow slides off easily, and is therefore unlikely to build up on top of the roof
- Their aesthetic design makes hip roofs a good choice on nearly any style home
- Construction requires the use of more building materials
- More prone to leaking, especially when dormers are added
- Hip roofs are sometimes challenging to ventilate, and may require more vents than other types.
Sometimes referred to as a French roof, a Mansard roof consists of four sides that each have two slopes. Each slope joins at the top to form a flat panel. Mansard roofs are often found on older homes, particularly those built constructed just after the Civil War.
- Sides may be either flat or curved to create a custom design
- Makes it easy to add open or closed dormers
- Ideal for adding a garret or attic living quarters
- The roof’s low pitch makes it difficult to shed snowfall
- Mansard roofs often contain many ornamental details, making them more expensive to construct
- Require more frequent maintenance and repairs than gable-style roofs
A shed roof consists of a single, sloping panel that is sometimes attached to a taller, adjacent wall. Shed roofs are sometimes known as skillion roofs or lean-tos. They are often used on rustic homes and cabins, as well as on storm shelters and hunting retreats.
- Shed roofs make it possible to cover porches and patios without reconfiguring a roof’s design.
- Require very few building materials
- Can be constructed even by those with little building experience
- Their simple appearance can detract from some homes
- Drainage problems may occur if the roof does not contain the proper slope
- Getting overhead utility lines through a shed roof is sometimes challenging
Ridged, multi-gable (M-type)
A ridged, multi-gable roof is one that consists of two separate gable roofs with a valley in between each section. When viewed from the front, the peaks of the gables form the letter “m”. They are often chosen for homes that have been added on to, since there is no need to reconfigure the main roof design.
- Excellent choice for townhouses, row homes, and duplexes, as a multi-gabled roof gives each unit its own distinction.
- Hold up well in high winds
- May be used in conjunction with other roof styles such as a shed or hip roof
- M-shaped roofs tend to have deep valleys where debris is likely to accumulate. This means they will require more frequent cleaning.
- Do not shed precipitation as readily as traditional gable roofs
- More expensive to repair or replace than a single gable or hip roof
A saw-tooth roof consists of alternating parallel slopes that give the appearance of a jagged saw blade when viewed from the side. Originally used on industrial buildings, they have become popular in modern home design as well.
- Ideal for homes with vaulted or cathedral ceilings
- Provides a sleek, contemporary appearance
- Windows may easily be placed into the vertical areas of the roof, allowing more light to enter the home
- Should not be used in areas where there is a great deal of snowfall or rainfall
- Can be complex to design, and are therefore more expensive
- Require more frequent repairs, particularly when dormers or windows are added
Dutch Gable Roof (Gablet Roof)
A Dutch gable roof is one that consists of a very small gable peak over top of a hip roof. It is sometimes referred to as a “gable on hip roof” or a gablet roof. This type of roof is often seen on Renaissance homes as well as ones with European architectural features.
- The gable peak adds a bit of visual interest to an ordinary hip roof
- Contains eaves on all sides, which serve to protect exterior walls from the elements
- Provides some shade for windows to help keep a house cool
- Some space inside the attic is eliminated with this type of roof
- More likely to leak than a traditional gabled roof
- May be more difficult to ventilate than an ordinary hip roof
When two inward sloping panels meet at a common valley, the result is known as a butterfly roof. A butterfly roof is the opposite of a gable roof, and somewhat resembles a butterfly’s wings while in flight. Their design makes them very popular on homes located in areas that receive a great deal of sunlight but very little rain.
- The central valley of a butterfly roof is ideal for collecting rainwater
- The shape allows for easy placement of solar panels
- Makes it possible to install larger windows that let more natural light in
- A butterfly roof must be carefully waterproofed in order to prevent leaks
- Drainage systems are prone to becoming clogged, and must therefore be cleaned out more often.
- Installing larger windows underneath a butterfly roof can result in hot and cold spots on the inside of a home
An A-frame roof consists of two slopes that extend nearly to the ground and reach a very high peak in the center. When viewed from the front, this roof will somewhat resemble the letter “A”. A-frame roofs may be placed on single or multi-story houses, and are often found on cabins, vacation homes, and guest cottages. They are ideal for locations that routinely receive a great deal of snow fall, which is why you may see them at ski lodges.
- They allow for a great deal of window space along the front and back
- Snow cannot accumulate on top of the roof due to its very steep slope. As such, the odds of a collapse are greatly reduced.
- One of the simplest roof types to build and maintain
- Due to the roof’s design, a great deal of space can be wasted in the attic area
- Water may pool around the home’s foundation unless there is adequate drainage
- The interior of an A-frame home can contain sloped walls, which may limit the placement of furniture and wall hangings.
Most Popular Materials for House Roofing
In addition to the above roof styles, you also have multiple choices when it comes to building materials. Here is an overview of the most popular building materials for residential roofing.
Shingles may be constructed from asphalt, fiberglass, or a combination of the two materials. Available in multiple color and pattern choices, they are among one of the most sought after roofing materials because of their durability and price.
Three tab shingles are most often used in new construction because they are an excellent value for the money. However, architectural shingles that resemble cedar or slate are becoming popular as well. Architectural shingles have an added advantage in that they are thicker and will therefore last longer.
Metal roofs have regained popularity in recent years thanks to advances in design that make them more durable than ever. Standing seam metal roofs easily shed snowfall, and are resistant to corrosion and wind damage. They are also available in nearly any color imaginable, so you no longer have to worry about your home having an industrial appearance.
Rather than metal panels, many builders these days are installing metal shingles. Made from durable aluminum, metal shingles have the same appearance as traditional asphalt or fiberglass shingles, yet provide you with the same protection as corrugated metal. With metal shingles, you get the best of both worlds!
Clay tiles are often used on Spanish or European style homes, and add a touch of elegance to any roof. Aside from a very long life expectancy, clay roofs are also fireproof and highly resistant to moisture or insect damage. They are however prone to breaking during high winds or hail storms.
Slate tiles are created from mined rock, and are one of the most durable materials on the market. Many slate roofs are hundreds of years old, making them well worth their initial investment. Even so, slate roofs do tend to be very heavy, and will therefore require some reinforcement in order to hold their weight.
PVC single ply membranes are most often used on flat roofs to prevent seams. They consist of thermoplastic material which is applied in a single layer and heat welded to create a strong, watertight fit.
Rubber EDPM (Ethylene Propylene Diene Monomer) is another flat roof material that is highly resistant to tearing. It is therefore ideal for flat roofs that are walked on often or structures that are prone to hail or wind damage.
Wood shakes or shingles are often created from redwood, cedar, or pine. They are often found on rustic or Cape Cod style homes, but may also be placed on more modern structures. Wood shakes are more cumbersome to apply than ordinary roofing shingles. As such, you should choose a specialist who is familiar with wood shingles if you do decide to go with them.
Which Roof Type is Best?
As you can see, there are multiple styles of roofs from which to choose. Not only that, but the sheer number of building materials means there is nearly an endless choice when it comes to roofs. Moreover, depending on the house siding type, your roof choice might change as well. Keep in mind the style of your home, climate, and your budget in order to come up with the design that is appropriate for you.
