I had three (3) Solatubes installed in my 1995 Baron home five years ago and have not had a single incidence of leaking. However, I am currently in rehab process of a 1991 Palm Harbor home and had my contractor install three (generic) 'skylights' that he purchased from Home Depot. With the first fall rain, a leak occured. The difference between Solatube and the Home Depot brand is substantial. If you desire to have skylights, do investigate the "Solatube" which delivers much better/truer light, has a better design to prevent leaking, is a metal tube rather than 'foil' and is installed by trained/experienced people. Good Luck!
