There are four main types of lighting used in homes: ambient, task, accent, and decorative. Within these categories, there are a number of fixtures to choose from including ceiling-mounted lights, floor lamps, under-cabinet lights, track lighting, and more. 

Choosing the fixture that’s right for you depends on your home design and the area you’re looking to illuminate.

Skylights are the most likely windows to leak if installed improperly, so there are a few questions you should ask any skylight installer before you hire them:

• Do you specialize in skylight installation or only windows in general?

• Do you offer any kind of warranty for the installation?

• What recourse do I have if the skylight leaks shortly after installation?

• Do you have references I can speak with?

• How long have you been in business?

• Are you licensed and insured?

Yes, you can install skylights on an existing roof, and it’s a common service that many homeowners opt for, especially on older homes built when skylights weren’t as prevalent. The installation process will be a bit more involved, and the design and planning process will take longer, meaning you’ll pay more to install a skylight on an existing roof than you would in new construction. The process involves cutting a hole in the roof, moving rafters, if necessary, and installing and sealing around the skylight.

Yes, you can cover up a skylight if you no longer wish to have it in your space. There are a few options for covering up a skylight. One option is to install a skylight cover or shade that can be easily opened or closed as needed, allowing you to control the amount of light entering the room. Another option is to cover the skylight with a solid material, such as plywood or drywall, effectively sealing it off. However, when covering a skylight, it's essential to ensure proper insulation and waterproofing to prevent any issues in the future.
