What Skylight Installers in Illinois Deal With

What a Day Looks Like as a Skylight installer in Illinois

He's on a roof harness before he's anywhere near the edge, because skylight work is fall work and the whole day is spent on a slope. The first job is a vented skylight in a master bath on an asphalt shingle roof. He locates the spot between the rafters from inside, marks it, then cuts the opening up top, knowing he'll have to cut and header a rafter to make the unit fit, which means doing the framing right so the roof's structure isn't compromised. The cut is the easy, scary part; the flashing is the part that determines whether this thing leaks in five years. He builds the curb, lays ice-and-water shield around the opening, sets the unit, and works the flashing kit in the right order, step flashing up the sides, head flashing over the top, everything lapped so water sheds over and never under. Counter-flashing and sealant finish it, but he knows sealant is the backup, not the system; the lapped flashing is the system. The afternoon job is on a tile roof, a completely different flashing approach, lifting and cutting tile and weaving the flashing into the courses without cracking the surrounding pieces. The homeowner can't understand why a tile-roof skylight costs more than the shingle quote her neighbor got. He talks her through it, then logs the roof type, unit model, and flashing detail for the file before harnessing down.

That daily chaos is what happens when your tools don't connect. After licensing, set yourself up with one integrated system from day one — Nexa is $279 once, or $99 today and two more payments.
