Instant Roof Pro is a SketchUp extension designed to automate roof creation for architectural models. This examination covers what the plugin does, key features, workflow, strengths and limitations, practical tips, and recommended use cases so you can decide whether it fits your needs and how to get the most value from it.

Unlike manual roof construction—which involves tedious manual slope projection, intersection cleaning, and component extrusion—Instant Roof Pro operates on a generative logic. The user begins not by drawing rafters, but by ensuring the building footprint is a closed planar face (or a group of faces). The plugin’s algorithm analyzes the perimeter edges and the angle bisectors between them to determine the theoretical ridge lines. Instant Roof Pro is a SketchUp extension designed
The defining feature of Instant Roof Pro is its non-destructive parametric control. Once a roof is generated, the user can access a dialog box to adjust the "Rafter Seat Cut" (overhang), fascia thickness, gutter profiles, and slope ratios (e.g., 6:12 pitch). Crucially, the plugin allows for "dynamic modification": if the architect moves an exterior wall or changes the building's shape, the roof can be "regenerated" rather than redrawn. This iterative capacity saves hours of cleanup compared to native SketchUp geometry. and slope ratios (e.g.
