# Roofs

Before framing roofs, you need to create wall types with layers and model the roofs correctly. Follow the guide below.

## 1. Create roof type layers

* Drywall and other finish layers should have **Finish 1**, **Finish 2** or **Substrate** function
* The main **studs** are hosted inside the **Structure layer** which has to be the **Core Layer** (layer between the two Core Boundaries)
* Each layer must have a defined **Function**, **Material** and **Thickness**

{% hint style="info" %}
**Suggestion**: Structure \[1] layer thickness should match the Web depth (d) of you rafters/joists. For example, if your rafters are 150mm, the Structure \[1] layer should have the same thickness.
{% endhint %}

{% hint style="success" %}
You can create as many layers as you wish.
{% endhint %}

For **double** drywall or other finish layers, each **Material** name must be **unique.**

## 2. Model roofs

After modeling **pitched roofs**, you need to use [**Roof Panel Layout** ](https://docs.besmart.software/common-for-several-products/roof-panel-layout)to divide them into smaller panels:
