Do skylights really leak?
The quick answer: No! VELUX skylights are engineered with three layers of water protection
and backed by an industry-leading 10-year installation warranty
that promises the skylights you put in your home will not leak.
But where did the concern about skylights leaking originate from? In the mid- to late-20th century, skylights were mostly made of plastic and called “bubble skylights.” This plastic was susceptible to damage from UV rays and normal weather conditions, leading the bubble skylights to become brittle and deteriorate, often resulting in leaks.
Then in the early 2000s, VELUX introduced our "No Leak" Skylights made with glass – not plastic – and three patented water protection layers. Depending on the type of skylight, these three layers include a gasket or deck seal, adhesive underlayment for secondary water protection, and engineered flashing for easy installation and primary water protection.
And to preempt any leaks whatsoever, VELUX “Fresh Air” Skylights (our line of venting “No Leak” Skylights) come equipped with rain sensors to automatically close the skylight at the first sign of rain.
