SKYLIGHT DETAILS
Step 1: Working from right to left, cut and install the first panel (#1). The next two panels are cut 1 1/2” from the curb of the skylight, and is
treated like an endwall detail with Z bar and closures. Next panel (#2) is cut and bent to fit, then installed.
Step 2: The next piece to install is the skylight pan (#3). First place a bead caulking or sealer tape on the top of panel #1 & #2 to stop any water
from siphoning at the joint. Next cut and bend the skylight pan to fit. The artificial ribs should be 1/2” high. Set and fasten.
Step 3: Before installing the upper panels, run a bead of caulking or sealer tape on top of the skylight pan parallel to the upper curb. Hold the
upper panels back far enough from the curb to allow the water to drain to either side. Generally 4” to 6” is sufficient depending on the width
of the skylight. Working from right to left, cut and install panel #4, snapping it into place and continue fastening as usual across to panel #5.
Step 4: Install trim item #6 as you would the standard end-wall flashing. Next apply trim items #7 - #8 finishing off around the curb of the
skylight. Trim items #6, 7 & 8 are generally all the same dimension.
General Notes:
- Caulking or sealer tape should be used at all joints and where the metal is to be overlapped.
- The overall finish appearance is determined by the care and attention to detail that is used when installing the flashings.
- The preceding information is designed as a general guideline to be used and is not the only acceptable method to flash a skylight.
