It's only a matter of time before a skylight begins to leak. Cutting corners rarely leads to a lasting result. Whether due to inferior materials or shoddy installation, there's no doubt that some conventional skylights have caused extensive, expensive water damage over the years. With the innovative Solatube Daylighting System, a non-traditional alternative to traditional skylights, there's no danger of a similar outcome. The device does not skimp on moisture controls. While the roof dome features an air- and water-tight design that sheds rainwater, its seamless steel flashing prevents always leakage, no matter the type of roof.
