Considering adding skylights to your existing home? If you're going to make cutouts in your residential roof to install skylights, you'll want to make sure your new windows will not do more harm than good.
Skylights can serve many purposes. They can let more natural light in, improve natural ventilation within a building, provide clearer views of the outside and aid in moisture control. That said, they can end up saving you or costing you money depending on how they are designed.
