Pros and Cons of Dormer Windows

Dormer windows are a useful feature if you wish to undertake some roof conversion in your home. A dormer is an extension of a building that protrudes from a sloping roof. To construct the window, you must create a frame within the roof. This creates a sort of small roof for the window unlike other windows in the house which are flush with the walls. Hence, the windows are also referred to as rooftop windows. The windows are a good idea, especially for large storied homes. Below are 4 pros and 3 cons of these windows.

1.   Increase Space

Rooftop windows increase the head height space in the uppermost levels of a home. This facilitates easier mobility within the room. The risk of collision with the ceiling is reduced. You may even wish to convert the space into an extra bedroom or study area. This enhances the functionality of upper space in the home.

2.   Ventilation

You can enjoy improved ventilation in your home with rooftop windows. The double hung design is especially popular in houses that don’t have air conditioning. This is because you can open them partially both at the top and bottom. A draft is subsequently created which facilitates the movement of hot air through the top while cooler air flows in at the bottom to replace the hot air.

3.   Functionality

Rooftop windows allow ample natural light to filter into the room. This enhances the ambiance within. The availability of natural light also allows you to utilize the space for various activities. The windows enhance both the internal and external character of your home. This adds value to your property.

4.   Versatile

Dormer windows are available in various shapes, sizes and styles. Pyramidal, arched, eyebrow, hipped, pedimented, composite and recessed designs are just some of the available options. It makes it easy to create a unique appearance for your home.


However, dormer windows are not without their disadvantages.


1.   Installation

The complexity involved in construction of the windows discourages some from installation. You require considerable technical skills and specific in-depth knowledge on the process to construct the windows properly. Installation also requires ample time, which may be unavailable in some cases. If poorly constructed, the windows can make your home look awkward.

2.   Cost

Installation of rooftop windows is quite costly due to the high level of technical knowledge involved. Any project that requires you to alter the roof of your house must be undertaken with caution. You must consult with a structural engineer or qualified roofing professional before installation of rooftop windows. The professional charges incurred contribute to the typically high costs of the windows.

3.   High Maintenance

The protruded design of the windows gives them higher exposure to the elements. This necessitates frequent maintenance. If neglected, they can easily develop damages and other structural problems. Air leakage and infiltration of moisture will result. This lowers the energy efficiency of your home. Faulty rooftop windows can cause you to incur higher energy costs. Unfortunately, since the windows are located on the uppermost levels, it is quite easy to forget about their care.
