Consider the Path of Sunlight over Your Home
Placing a skylight on a south-facing roof slope can overheat some rooms in some climates. By contrast, skylights on a north-facing slope admit more diffuse light. If you want a dramatic, "sun-splashed" effect, you won't get that with a north-facing skylight. Many homeowners choose tinted glass for their skylights - particularly south-facing ones - to limit fading from sunlight coming through the skylight.
Don't Be Afraid to Think Big
Just because you have a small room doesn't mean you need a small skylight. The cost of installation doesn't vary much with size, so don't be afraid to order a skylight of generous size if you want to add a lot of light. A small room with a generous-sized skylight will look dramatic, while a large room with a tiny skylight may look odd.
Consider Tubular Skylights for Tiny Spaces
Sometimes, however, a small skylight is the right choice. A tiny interior bathroom without windows can be the perfect place for a tubular skylight. Tubular skylights consist of a small dome on the roof, a reflective tube running through the attic and ceiling, and a dome-shaped or flat fixture in the ceiling.
Don't Forget About How it Looks from the Outside
Consider how a skylight looks on your exterior roof line. In general, you want to align your skylight with a window, door, or other architectural feature to avoid a random look. It's also a good idea to avoid placing skylights on roof surfaces that are street-facing, particularly on older architecture styles. Skylights come in a dizzying array of styles and can be made to suit any roofline or architecture while bringing welcome light inside your home.
