New roof
A new roof must ensure:
- Weather resistance (waterproofing, resistance to wind, adequate drainage...)
- Load resistance for instance snow load
- Resistance to heat loss
- Fire resistance depending on your project
- Ventilation.
Of course, a new roof usually means a work permit.
Existing roof
A permit may be required if
- The repair or reroofing is more than 25% of the roof area
- You may cause structural alterations, even cracks in the structure
- You change the roof performance, like a lower fire resistance.
