It is easy to focus all your attention on choosing the perfect skylight and forget about the part that actually keeps your home dry. A velux skylight flashing kit is a crucial part of any complete skylight system, and getting this detail wrong is one of the most common reasons skylights end up leaking years after installation.
VELUX flashing kits are engineered to shed water without relying on sealants or caulking that can dry out, crack, and fail over time. Instead, the flashing system is built to physically direct water away from the opening using overlapping, interlocking pieces designed for specific roofing materials. This is why there is no single flashing kit that works for every home. Your roof type and slope determine exactly which kit is right for your installation.
For deck mounted skylights, the options include the EDL kit for shingles and shakes, which uses step flashing pieces that interweave directly with the roofing material for proper drainage, along with additional step pieces for thicker materials like shakes. There are Combi kits for groupings of multiple skylights, available in versions suited to low-profile materials like shingles or high-profile materials like Spanish tile and corrugated metal. Tile roofs use the EDW kit, which features patented sill flashing with pliable pleats that mold to the shape of the tile, along with side and head flashing pieces that form a gutter to channel water safely away. Metal roofs use the EDM kit, where the flashing pieces interlock with the roofing material for a fast, weathertight seal. For a premium finish, copper cladding and flashing options are also available as special order items.
If you are working with a site-built curb on a low-sloped roof, the Biepack ECB flashing kit is designed specifically for that application, applied directly to lumber and plywood without any bending required. Curb mounted skylights have their own dedicated kits as well, including ECL for shingles and shakes and ECW for tile roofing, each built around the same principle of directing water rather than simply sealing against it.
One important note for anyone comparing products: flashing systems are not required for pan-flashed skylights or for VELUX Sun Tunnel Skylights, since those units use a different, self-contained weatherproofing approach.
Choosing the correct flashing kit is not something to guess at or leave to trial and error. It needs to match your exact roofing material, your skylight model, and whether the unit is deck mounted or curb mounted. An improperly matched or poorly installed flashing kit is one of the fastest ways to end up with water damage, mold, or a callback repair down the road.
