Instant Roof Pro Sketchup Plugin Jun 2026

Comprehensive Report: Instant Roof Pro for SketchUp 1. Executive Summary Instant Roof Pro is a commercial extension developed by MindSight Studios (now part of the broader SketchUp extension ecosystem). It is widely considered one of the fastest and most intuitive tools for generating complex, fully editable 3D roofs directly from 2D floor plan geometry. Unlike SketchUp’s native tools, which require manual extrusion, rotation, and intersection, Instant Roof Pro automates the entire process, saving hours of modeling time for architects, builders, and 3D artists. 2. Core Functionality The plugin’s primary function is to select a closed planar face (a room outline) and instantly generate a parametric roof. It supports a wide range of roof styles: | Roof Type | Description | | :--- | :--- | | Gable | Standard pitched roof with two sloping sides. | | Hip | Roof with slopes on all four sides. | | Gambrel | Barn-style roof with two distinct pitches per side. | | Mansard | French style with steep lower slope and shallow upper slope. | | Pyramid | A hip roof that comes to a single point. | | Shed | Single sloping plane (lean-to). | | Flat | Flat roof with parapet options. | Key automated features:

Automatic Valley & Hip Creation: Detects internal and external corners to create valleys (inside corners) and hips (outside corners). Overhang Generation: Adds eaves and soffits with user-defined depth. Gable Wall Construction: Automatically builds triangular gable walls under the roof ends. Vents & Dormers (Pro): The Pro version includes parametric dormers (gable, shed, eyebrow) and roof vents.

Prepare Floor Plan: Draw or import a 2D floor plan. Ensure all exterior and interior walls form clean, closed faces (no gaps). Select Face(s): Click on the face representing the room or building footprint. You can also select multiple faces for complex, multi-wing buildings. Launch Plugin: Click the Instant Roof Pro icon. Configure Settings: instant roof pro sketchup plugin

Roof type (Hip, Gable, etc.) Pitch (e.g., 6:12, 8:12) Overhang distance Fascia/soffit thickness

Generate: Click "Create Roof." The roof geometry appears instantly as a group.

Editing:

Right-click the roof group → Instant Roof > Edit . Change any parameter (pitch, overhang, type). The roof regenerates without losing manual edits made to gutters, shingles, or structural elements (as long as the core group structure remains).

5. Advanced Pro Features (Differentiating from Standard Version) The "Pro" designation adds several powerful capabilities: | Feature | Benefit | | :--- | :--- | | Multi-Wing Roofs | Handles L, U, T, and H-shaped buildings, automatically solving complex valley intersections. | | Parametric Dormers | Drag-and-drop dormers that automatically cut the main roof and form proper flashings. | | Roof Vents & Chimneys | Library of parametric penetrations. | | Dynamic Components | All generated roofs are SketchUp Dynamic Components, allowing pitch and overhang changes via the Component Options window. | | Automatic Fascia & Gutters | Can generate fascia boards and gutter profiles along all edges. | 6. Limitations & Considerations While powerful, Instant Roof Pro is not a full structural engineering tool:

No Structural Load Analysis: It creates visual geometry, not an engineering model. You cannot run stress calculations. Complex Curved Roofs: Does not generate domes, conical roofs, or free-form curved roofs (e.g., Zaha Hadid style). Use Artisan or SubD for those. Tile/Slate Patterns: Does not automatically apply realistic shingle or tile textures with overlapping 3D tiles. Use Skimp or Texture Tools for that. Learning Curve for Complex Buildings: While simple roofs are one-click, multi-wing roofs require understanding how the plugin interprets inside vs. outside corners. Users may need to add temporary guide lines for very complex intersections. Version Compatibility: Always check compatibility with your SketchUp version (e.g., SketchUp 2021–2025). Older versions may not work with the latest SketchUp release. Comprehensive Report: Instant Roof Pro for SketchUp 1
