• determining the location for a first opening in said roof and a second opening in said ceiling;
• removing sections of the roof and the ceiling to create said first and second openings;
• securing a roof mount over said first opening;
• said roof mount comprising a base and a cylindrical first sleeve defining a first aperture and having an upper edge and a lower edge;
• wherein said roof mount base and lower edge of said cylindrical sleeve are positioned flush against said roof;
• securing a ceiling mount over said second opening;
• said ceiling mount comprising a substantially cylindrical second sleeve having an upper sleeve section and a lower sleeve section and a first tapered step between said upper and lower sleeve sections;
• wherein said upper sleeve section extends through said opening in said ceiling;
• and
• positioning a tubular body having a first end with a supporting lip and a straight second end and a cylindrical body therebetween defining a second aperture, through the first aperture in said roofing mount;
• wherein the supporting lip rests on the upper edge of the cylindrical first sleeve and the upper sleeve section of the ceiling mount extends into the second aperture of the cylindrical body and the straight second end rests on said first tapered step of said ceiling mount.
