Can I put a metal roof over existing shingles?

In Syracuse? Yes, you can install a metal roof over existing shingles, but it depends on the condition of the shingles and local building codes. 

Benefits 

  • Saves money: Avoids the cost of removing the old roof
  • Saves time: Avoids the time-consuming process of removing the old roof
  • Insulation: Metal roofs reflect heat away from the surface, which can help prevent heat from escaping
Considerations
    • Shingle condition
      Shingles should be near the end of their lifespan and not cracked, blistering, or bumpy 

  • Building department approval
    Check with your local building department to see if this is an approved installation method 

  • Plywood condition
    The plywood that the existing shingle roof is attached to should be in good shape 

  • Weight
    The added weight of the metal roof may affect the structure of the building 

  • Leaks
    Leaks can be difficult to track and repair when a metal roof is installed over shingles 

Installation
You can attach the metal roof panels to a framing system that’s installed directly over the existing shingles.
