  4. Tubular skylights: These are small roof window units that use a reflective tube to bring natural light into the room. They can be a great addition to tiny spaces such as closets, bathrooms, or hallways.

  5. Round skylights: These skylights have a round or circular shape and are normally installed on a roof or a high wall. They can be made from various materials and come in different styles and sizes.

  6. Custom skylights: These skylights can be made to suit your particular needs and preferences. You can choose the size, shape, and material of your replacement window. They can be an ideal option for unusual and unique spaces.

Types of roof constructions

Skylights can be designed to fit different kinds of roofs. Based on that they can be divided into a few types, including:

Flat roof skylights

As their name suggests, these windows are intended to be installed on flat or low-slope roofs. They can be made of glass or polycarbonate material and might be fixed or operable. Flat roof skylights are also available in different sizes and shapes including round, tubular, and pyramid. When installed flush with the roofline, these windows can give a very stylish and modern appearance to the building.

Pitched roof skylights

These are roof windows installed on buildings with sloped roofs. As with flat roof skylights, these windows can be made from various materials as well as in various shapes and sizes. They can provide your property with a very sleek and modern look. However, pitched roof skylights are usually more expensive due to the complexity of the installation process.
