I'm sure you've wondered how differently your home would feel with a skylight illuminating from the ceiling. Providing balanced, natural light from above, they can brighten your home and make colors appear more true.

The Best Skylight Types for Flat Roofs


There are a couple of issues that can occur with skylights that are placed on flat roofs. The main problem is rainwater collecting on top. Pooling water on a skylight will potentially cause costly water leakage, leading to even more issues. 

Because of this potential inconvenience, your installer can choose an option made with curved glass, or they can build the curb at an angle to allow the water to run off the skylight. Below is an overview of each type compatible with flat roofing to help you brainstorm which may be the best fit for your home. 

Roof Access Skylight 


Roof access skylights are known for pleasing the eye and brightening spaces with natural sunlight's luminescence. Providing access to your roof, you can allow fresh, filtered air through the ventilation flap.

Curved Flat Roof Skylight 


This type of skylight is a unique design that was created to transform virtually any space with natural light. Its design allows rainwater to run smoothly off its curvetech glass or polycarbonate dome, preventing leaks.  

Curved Flat Roof skylights stand out, offering a modern look and feel. Because of their maintenance-free design, there's no need to clean the glass surface regularly, while toughened glass makes them stand firm against damage. The price for this particular skylight can range from $950 to $1,900, depending on what material and size you choose from.

VELUX TCR Sun Tunnel


With a crisp, circular design, the VELUX TCR Sun Tunnel is designed to add a ray of natural light to any part of your home. These are made to capture light through a high-impact dome on the roof, sending it through a highly reflective tunnel. From there, pure natural light is transmitted with no color shift. If you're looking for an option that's modern and functions like a dream, this one may be perfect for you.


Featuring an adjustable pitch adapter, tunnel installation enables more light to be captured. Another fantastic feature of this skylight is its Flexi Loc System. It's a tunnel connection system that cuts tunnel installation time in half, displaying reflective tunnels that deliver high-quality daylight. Prices for the VELUX TCR Sun Tunnel range from $650 to $2,150, depending on what size you choose.
