Instant Roof NUI is a premium plugin for SketchUp designed to automate the creation of complex roof structures like hips, gables, and mansards.

1. Flex Seal Liquid (Best for Flat Nui Cracks)

• Pros: Thick, brushable, works on wet surfaces, remains flexible.
• Cons: Takes 24 hours to fully cure; not great on steep slopes.
• Best for: RV roofs, flat mobile home roofs, valleys.

Pro Tip: Keep a tube in your garage. When a storm blows a branch through a roof tile or pops a nail, this will save your ceiling from water damage for the next 6–12 months.

Step 3: Apply Primer (Critical) Wipe the cracked area with the supplied Nui primer or isopropyl alcohol. This removes oils and activates the asphalt. Wait 30 seconds for the flash-off.

CAD Fixer Tool: This feature attempts to repair imported CAD models by automatically placing new faces in a group to close gaps and fix input errors.
