SKYLIGHT INNOVATIONS

Let's exist realistic: you're probably not going to exist the one who physically installs your skylight. Unless you're experienced in construction or roof piece of work, installing skylights is not your typical DIY housing projection.

Nonetheless, that doesn't mean you can't be informed on all the ins and outs of your skylight installation. And ane of the biggest factors that determines which skylight you become and how information technology's installed is the type of roof you have.

Covering Materials and Installation Types

Generally, your roof is going to autumn into 1 of three categories: a shingle roof, metal roof, or tile roof. Metal roofs can only support deck-mounted skylights, only if you lot have shingle or tile covering, you accept the selection to choose between deck-mounted or adjourn-mounted skylights. Now, what the heck exercise deck- and curb-mounted mean?

Deck-mounted skylights are nailed directly to your roof deck (the trusses and joists between the structural components of your roof). This gives them a lower profile on your roof and makes them ideal for new construction homes or make new skylight cutting-ins.

Adjourn-mounted skylights are more common on low-sloped roofs. They're installed on a curb or frame - normally made of ii-by-fours - that your installer attaches to the roof. Call back of curb-mounted skylights similar a shoebox: the curb is the box and the skylight is the chapeau.

Both deck- and curb-mounted skylights look the same from the inside, so your roof's type and slope will likely be the determining factors for which style you install. But for a skylight installation to exist complete, y'all need flashing.

Coming Within: Apartment vs. Vaulted Ceilings

Actually, this is one of the most common misconceptions regarding skylights.
