Before installing a skylight, it is important to consider the size and shape of the skylight, as well as its potential location. Additionally, it is essential to take into account the direction of the sun in relation to the room’s orientation when deciding upon the area for placement. It is also important to check local codes and ordinances to make sure that all regulations are met. Moreover, an inspection of the roof should be conducted to ensure that there aren’t any structural issues or problems with ventilation due to limited airflow. Finally, professional installation is recommended in order to ensure safety and proper operation of a skylight.
