Put a New Roof On the Existing One?

In most cases, you can install a new roof over an existing one, but it depends on several factors:

  1. Local Building Codes: Check your local building codes. Some areas allow only one layer of roofing, while others permit two. No one allows three layers. 

  2. Roof Condition: The existing roof must be in good condition. If it's damaged or has structural issues, it's better to remove it first.

  3. Weight: Adding a new layer increases the weight on your roof structure. Ensure it can handle the additional load.

  4. Material Compatibility: Make sure the new roofing material is compatible with the old one.

Always consult with a roofing professional to get the best advice for your specific situation.
