Decks and patios are a major source of America's entertainment and relaxing enjoyment, but they can be hot in the summer sun. They can actually be dangerous if they reflect the sun's ultraviolet rays. And running your grill during a rainstorm that arrives the same time as your guests can be a real frustration. One answer is a sunroof over your patio or deck. If designed properly, a sunroof can cut the summer sun, but still allow winter sun rays to warm the house. The sunroof shown is a typical do-it-yourself project, placed over a wood deck, although sunroofs can also be constructed over patios as well. For a step-by-step at the construction process, take a look at this DIY video tutorial.
