Re-roofing with materials identical in type and size to the existing roof, and you're not making any structural changes. However, this can vary depending on local codes and the exact condition of your current roof.

Consulting a Professional Roofer

If you're unsure about whether you need a permit, it's always best to consult with a professional roofer. They can assess your project, understand local codes, and guide you through the process.

Many roofing contractors include permit costs and the process of obtaining them in their service. So, it's worth asking if they can handle this part for you.

In conclusion, while the need for a permit can vary, it's always better to err on the side of caution. A small investment of time and money upfront can save you headaches and potential penalties later on. So, before you tear off that old roof, make sure you've covered all your bases.
