Pro Tip: If you are using SketchUp 2020 or earlier, ensure you have the latest LibFredo6 installed, as many advanced roofing scripts rely on Fredo6’s language libraries for geometry processing. Let’s simulate a real-world application. You have drawn a two-story house with a complex garage bump-out.
By automating pitch calculation, intersection cleaning, and texture mapping, the plugin frees you to focus on design innovation rather than technical drudgery. Download the trial today, draw a simple rectangle with four walls, and see for yourself how a perfect hip roof appears in under ten seconds. Once you go Pro, you will never manually model a roof again.

In this comprehensive guide, we will dissect everything you need to know about this powerful extension: from basic installation to advanced parametric workflows, and why it is considered the "gold standard" for roofing solutions in the SketchUp ecosystem. The Instant Roof Pro SketchUp Plugin is a premium extension developed by Vali Architects (now distributed via SketchUcation and the Extension Warehouse). Unlike basic freeware tools that simply extrude a triangle, Instant Roof Pro is a parametric roofing solution. It automatically detects the external perimeter of your building’s walls, recognizes internal corners (valleys) and external corners (hips), and generates a fully textured, pitch-accurate roof in seconds. Pro Tip: If you are using SketchUp 2020
Open the Instant Roof Pro dialog. Set pitch to 8:12 (moderate steepness). Set overhang to 18 inches. Choose "Asphalt Shingles" from the texture library. navigate to Extensions >
Select the top edges of your wall group. Click the "Create Roof" button. Watch the magic happen: The plugin calculates the primary roof over the main rectangle, then automatically calculates the second roof over the garage, intersecting them into a clean valley.
Purchase or download a trial from the official SketchUcation store or Extension Warehouse. Step 2: In SketchUp, navigate to Extensions > Extension Manager . Step 3: Click "Install Extension" and locate the .RBZ file (the standard SketchUp extension format). Step 4: Restart SketchUp. You will find the Instant Roof toolbar (usually a small house icon with a roof).
