Tubular skylight with dome flashing and protective corrugation

Abstract

In a tubular skylight, a corrugated Aluminum sheet is formed with a hole that is pressed into a curb which is fastened over the turret of a roof-mounted skylight flashing. Roof tiles above the dome of the skylight are placed onto the sheet, while below the dome the sheet is placed over roof tiles and manually conformed thereto, owing to the corrugations. Any water that leaks past tiles above the dome will be directed by the sheet around the curb and down onto the tops of tiles that are below the dome, thereby providing a water seal for the skylight.

1 . A tubular skylight, comprising: 
 a transparent dome;    a flashing coupled to the dome to mount the dome on a roof;    a skylight tube depending downwardly from the dome; and    a sheet of corrugated metal mounted on the roof and coupled to the flashing, the sheet having a hole formed therein, the hole defining a continuous, closed periphery closely spaced from the flashing, the sheet being conformable to roof tiles to provide a seal, the sheet being corrugated around the entire periphery.    
   
   
       2 - 5 . (canceled)  
   
   
       6 . The skylight of  claim 1 , wherein the sheet is made of a single piece of material including at least one of: Aluminum, Copper, Lead, malleable Zinc, plastic, and rubber.  
   
   
       7 . The skylight of  claim 1 , wherein the roof defines an incline and the sheet defines elongated corrugations extending generally parallel to the incline when the sheet is mounted on the roof.  
   
   
       8 - 13 . (canceled)  
   
   
       14 . A lighting system comprising: 
 a transparent skylight cover;    a light diffuser;    a tubular structure extendable between the cover and diffuser; and    a single corrugated sheet configured for circumscribing the tubular structure between the cover and the diffuser to impede water leakage through a roof above which the cover is to be disposed, the sheet including structure coupled to a flashing associated with the cover.    
   
   
       15 . The system of  claim 14 , wherein the flashing is couplable to the cover to mount the cover on a roof and at least one skylight tube is configured for depending downwardly from the cover.  
   
   
       16 . The system of  claim 15 , wherein the sheet has a hole formed therein, the hole defining a periphery closely spaced from the flashing.  
   
   
       17 - 18 . (canceled)  
   
   
       19 . The system of  claim 15 , further comprising a flashing extension coupling the flashing to the cover.  
   
   
       20 . The system of  claim 14 , wherein the sheet is made of a material selected from the group consisting of: Aluminum, Copper, Lead, malleable Zinc, plastic, and rubber.
