ZS COMP INSTALLATION MANUAL FOR COMPOSITION SHINGLE ROOFS - U.S.
4.5 Roof Zones
Roof zones identify the interior, edge and corner regions of each designated roof plane. This is to
take into account varying wind pressures as the wind passes over different areas of the roof. The
maximum allowable Leveling Foot spacing may be smaller in edge and corner roof zones.
Figure 4.10 Roof Zone Example (U.S.)
NOTE:
When generating array layouts, the Zepulator assumes that the entire mounting
area is within an Interior roof zone. For detailed examples showing applications
of array layouts within edge and corner roof zones, and how to determine the
dimensions of these zones, please refer to the Engineering Certification Letter
and Span Tables document that is appropriate for the project location.

The determination of the edge
and corner zone dimensions is
country-specific, as described in
the Engineering Certification
