The cost of a Solatube Daylighting System depends on a few things, so there is no single price. The main factors are the model you choose, your roof type and pitch, how long the tube run needs to be and how many angles it takes, and any add ons like a Daylight Dimmer or tube extensions. Your location plays a part as well. The best way to get a real number for your home is a free in home estimate, where we can look at the roof and the rooms and price it exactly.
