How is a Solar Tubular Skylight Installed?

Skylight installation means cutting a hole in your roof. Sound scary? It’s not if you know how a solar tubular skylight is installed!

The flashing for a tubular skylight dome is slipped under the shingles and the waterproofing layer on a typical shingle roof. Once the proper sized hole is cut in the shingles and roof sheathing, the shingles are further trimmed to go neatly over the top half of the wide flange around the housing. Sealant is used under the flange as a secondary barrier to water penetration.

The lower half of the flashing sits atop the shingles and waterproofing. Water flowing around the housing is directed over the lower courses of shingles, keeping moisture where it belongs!
