3D Roof Design Software
Cedreo lets professional builders, remodelers, and contractors create stunning 3D roof designs that help them close more deals.
How to Use Online Roof Design Software
More than just a roof design software, Cedreo accelerates every step of the house design process, from creation to presentation.
Once you’ve created your project’s foundational layout, you can work with the roof editing tool to wrap up the exterior design.
In just a few clicks, you can build a roof that perfectly complements the rest of your hard work.
Draw the Roof in 1 Click, Then Choose the Layout
Thanks to an intuitive interface, it’s simple to add roofing to your house layouts. Start at the Roof tab.
- Once you’ve finished the 2D floor plan with exterior walls, select Automatic Roof Detection.
- Select the roof shape: single slope, gable, multi-slope, or flat roofs.
- Click the check box on the floor plan.
- Cedreo automatically adds a roof that you can see on the 2D and 3D plans.
Customize the Roof Settings
Use the side pane options to dial in the roof structure and edge parameters to match exactly what you need.
- Adjust roof height and set pitch using angle or percentage of the slope.
- Fine-tune thickness so your roof design reflects your build intent and interior ceiling conditions.
- Set ridge offsets and leave overhangs.
- Add soffit if needed.
Finish it With Dormers, Gutters & Downspouts
Finish the new roof with details that impact both curb appeal and functionality.
- From the Roof and Wall Opening tabs, drag and drop dormers, roof windows, skylights, gutters, and downspouts.
- Resize and reposition roof elements so everything aligns cleanly with windows, walls, and elevations.
- Review the roof layout in 2D while checking the exterior in 3D for fast quality control.
- Add finished 2D roof plans and 3D roof views to your project presentations.
Fast & Detailed Roof Plans
Cedreo helps you create a roof plan that communicates roof designs clearly to homeowners.
- Accurate roof layout: Draft a clean outline from your floor plan perimeter with the ability to refine edges and roof structure details.
