If you have a skylight, you are a fortunate homeowner. Skylights can brighten up any room, and make for an aesthetically pleasing way to open up the interior of your home.
However, you must keep that skylight watertight. Having, essentially, a hole in your roof, you must make sure that it is not taking on moisture.
The key to achieving this is your skylight flashing.
What do you need to know about your skylight flashing, as it relates to the rest of your roof?
Skylights often have their own integral flashing
Commonly, skylight flashing is constructed as part of the skylight. When it is first installed, that flashing is built right into the structure of the window itself. If this is not the case, then the skylight will have saddle flashing across the top of the window, step flashing running along each side, and continuous flashing along the base of the skylight.
DIY flashing may have issues
Home-handyman sites show a variety of ways to install your own skylight flashing. And while we do not want to discourage you from working on your own home, this flashing is of tantamount importance to the health of your roof. Misapplied or leaky flashing could cause you tens of thousands of dollars worth of damage. Step into home-fix flashing scenarios with caution.
Curb mounted skylights are smart
With a curb mounted skylight, there is a gasket. The skylight is mounted onto the curb, and then the gasket forms a tight seal between the curb and the skylight. Deck mounted skylights are also available, but these curb mounted skylights tend to be more common.
