At the present time, unit skylights are required to be tested and labeled in accordance with the same standard in both the IRC and IBC. Unit skylights will also be exempt from a requirement of the IRC and IBC for saddle or cricket flashing of large roof openings. It is more appropriate for the installer of these skylights to instead rely upon the installation instructions of the skylight manufacturers, as currently occurs for windows.
How do you skirt IBC/IRC cricket requirements?
