Dormer windows can be a game-changer for homes with limited space. They can be installed on any roof pitch and are available in a range of styles.
A flat roof dormer is a great option for modern homes, adding a touch of sleekness to the exterior design. This style is ideal for homes with a flat roof or a very shallow pitch.
A gable dormer is a more traditional option, featuring a triangular roof that matches the existing roof pitch. This style is perfect for homes with a classic or vintage look.
A shed dormer is a great choice for homes with a steep roof pitch, adding a functional storage space to the attic. This style is also ideal for homes with a minimalist exterior design.
Types of Dormer Windows

There are several types of dormers to choose from, each with its own distinct style. Arched top dormers are a popular choice, adding a touch of elegance to any roofline.
Some dormers are designed to be more subtle, like the blind or false dormer, which doesn't project out from the roof. Eyebrow or eyelid dormers are another option, offering a more minimalist look.
If you want to add some extra space to your attic, a gabled dormer or a hipped dormer might be the way to go. These types of dormers can be quite functional, but they also come in a range of styles to suit different tastes.
Other options include the lucarne, nantucket, pediment, polygonal, pyramid, recessed, shed, steep roof shed, and wall dormer. Each of these types of dormers has its own unique characteristics, so it's worth doing some research to find the one that best fits your needs.

Window Styles
Window Styles can add a lot of character to your dormer windows. There are many different styles to choose from, each with its own unique benefits.
A gable window style is a classic choice, with a triangular shape that fits perfectly into the dormer's roof. This style is often used to bring in natural light and provide a view of the outside.
A casement window style is another popular option, with a single piece of glass that hinges at the side. This style is great for small dormer windows, as it allows for maximum natural light and ventilation.
A double-hung window style is also a good choice, with two separate sashes that move up and down. This style is perfect for dormer windows that are a bit larger, as it provides excellent ventilation and can be easily opened for a breeze.
Double Hung
Double Hung windows are a popular choice for dormer installations, featuring two sashes that move up and down independently for excellent ventilation control.
This design allows you to create a natural airflow that helps push hot air out through the top while drawing cooler air in from the bottom, improving comfort and reducing energy costs during warmer months.
Double Hung windows add subtle character and sophistication to your home's exterior, making them a timeless choice for many homeowners.
By opening both the top and bottom sashes, you can control the airflow and take advantage of the benefits they offer.
Casement
Casement windows are a great choice for dormer installations because they offer excellent ventilation and a tight seal when closed, making them an energy-efficient option.
The simplicity of casement windows makes them well-suited for cottage-style homes or those seeking a more minimalist aesthetic, with clean lines and unobstructed views creating a sense of openness in smaller dormer spaces.
Casement windows can make smaller dormer spaces feel larger and more inviting by providing unobstructed views.
Their functionality and ease of operation make them a practical choice for various architectural settings.
Home Styles and Designs
Dormer windows can add architectural interest to your home. They can also provide natural light and space.
No matter the style of your house, dormers can be customized to fit your unique aesthetic. You can choose from different types of windows, including gabled, shed, hipped, and eyebrow.
Dormers have been a part of Western architecture for centuries, originating in France as a feature of attic sleeping rooms. They're also commonly found in English Gothic and Catholic churches.
Cape Cod
Cape Cod houses are the classic American beach home, especially in places where real estate is tight and expensive.
In these areas, dormer windows are a clever solution to extend upper living space without increasing a home's footprint.
Dormer windows on Cape Cod homes provide an elevated viewpoint, allowing homeowners to overlook dunes and grasses and enjoy ocean air and sea breezes.
Homeowners who want this look but can't afford the real thing might consider adding fake dormer windows, which are solely an aesthetic add-on to the roof and don't actually break through the roof or connect to the interior of the home.
Home Designs
Dormers can be customized to match your home's unique style and aesthetic.
A small structure that projects out from the sloped roof of a home, a dormer can add headroom, natural light, and airflow to previously underutilized attic spaces.
For those looking to finish an attic into livable square footage, dormers are a great option.
Dormer windows come in various styles, including gabled, shed, hipped, and eyebrow roof shapes.
What Kind of Houses?
Dormers have been a part of Western architecture for centuries.
Historic homes built before the mid-1900s often have dormers, which were originally a feature of an attic sleeping room or bedroom in France.
Many single-family or semi-detached homes in the United States have dormers today, which adds a touch of style to their design.
English Gothic and Catholic churches also feature prominent dormers, showcasing their significance in architectural history.
Newly built homes may have dormers as part of a loft conversion or simply for aesthetic appeal.
Installation and Costs
Installation and costs can be a significant factor in your dormer window project.
The cost of permits, insurance, and inspections can add up quickly, so it's essential to factor these costs into your budget.
Labor costs and availability can also impact the overall cost of your dormer installation, so be sure to hire a reliable contractor.
Paints, materials, and finishing costs will also depend on the style and size of your dormer, as well as the type of roof you already have.
A larger dormer or multiple dormers will require more materials and labor, increasing the overall cost.
Here are some factors that can affect the cost of your dormer installation:
- Cost of permits, insurance, and inspections
- Labor costs and availability
- Paints, materials, and finishing costs
- Rubbish removal
- The size of the dormer and how many you'd like
- The style of the dormer
- The type of roof you already have
- Where you want it installed
Determining Installation Costs
Determining installation costs for a dormer can be a bit tricky, but it's essential to get it right. The average cost of installing a dormer is around $12,000, but prices can range from $2,500 to $30,000 depending on the size, quantity, and design of the dormer.
You'll want to get detailed quotes from a few contractors to understand both the short-term and long-term costs of the project. This will help you make an informed decision and avoid any unexpected expenses down the line.
The cost of permits, insurance, and inspections can add up quickly, so be sure to factor these costs into your overall budget. Labor costs and availability can also impact the final price, so it's essential to work with a reputable contractor who can deliver the job on time.
The size and style of the dormer will also play a significant role in determining the final cost. A larger dormer will naturally cost more to install, and the style of the dormer can also impact the price. For example, a more complex design may require more materials and labor, increasing the overall cost.
Here are some key factors to consider when determining the installation costs of a dormer:
- Cost of permits, insurance, and inspections
- Labor costs and availability
- Paints, materials, and finishing costs
- Rubbish removal
- The size of the dormer and how many you'd like
- The style of the dormer
- The type of roof you already have

Installation Expectations
When you're having a new home built, the framing contractor will construct the frame of the dormer at the same time the roof structure is framed.
Sheathing is attached to the outside dormer walls and over the rafters of the main roof at the same time, covering the framing studs.
The next step is the installation of a vapor barrier wrap over the sheathing on the vertical walls of the dormer.
The window is usually installed next, followed by the roofing contractor installing the shingles over the dormer roof and the main roof at the same time.
This seamless layer of shingles provides a cohesive look, as it can be difficult to perfectly match new shingles to existing ones.
The interior of the dormer is finished at the same time the interior loft space is finished, with painting and trimming included.
In existing houses, the main focus is to reduce the amount of time you have a gaping hole in your roof, so interior framing is often done first.
The contractor then constructs the exterior frame of the dormer on the surface of the roof, followed by cutting a connecting hole through the roof.
Any necessary additional framing takes place after that, before the window is installed.
The dormer can then be wrapped with a vapor barrier and the exterior and interior can be finished as desired.
