ZTM Tile Flashing Kit for Velux Sun Tunnel

In all the years that I have sold, repaired and installed skylights, I have never come across an intact skylight that leaks. There are generally a few reasons that people have leaks related to a skylight:
Incorrect or improper installation - The skylight was installed incorrectly and water is leaking in from around the skylight, not through it.
Broken acrylic skylight - The skylight is old and degraded from sun and weather, has either spontaneously broken or it was hit by something and broke. Problems also arise on acrylic skylights when someone decides to apply sealer or caulk at the junction of the skylight and the frame, usually because they have water coming in. This does not allow the skylight to expand and contract with changes in temperature, as it was designed to do. This will definitely shorten the lifespan of an acrylic skylight and make fracture inevitable! Acrylic skylights definitely have a lifespan; it may take 2 years, it may take 10 but at some point it will break and need replacement.
Roof failure - There is a problem with the roof, and water will find its way through any openings in the roof. It may not become evident until the drywall starts to stain or sag.

When you order from The Skylight Guy, all products are drop shipped directly from the manufacturer. They are always brand new, in original packaging from the factory.

VELUX products are sent from the closest distribution center to you and are generally shipped via a freight company. For this reason there are no tracking numbers per se. Product leaves the factory 1-2 business days after you place your order. If the package is not received in the expected time we can have it tracked through VELUX.

Natural Light products ship within 24 hours on business days by FedEx or UPS. By the time we receive tracking information on the products, you will usually have it. If the package is not received in the expected time we can track it.
