A roof replacement on a residential or commercial property is different from a straightforward new roof installation because of two key factors – knowing when it’s time for re-roofing, and understanding what’s involved in removing an old/existing roof.

When is it time to re-roof?

You would consider a roof replacement when:

  • the existing roof has reached a certain age and is no longer structurally sound, safe or weather tight
  • there has been significant damage or wear and tear – usually this, plus the age of the roof, make it more efficient and economical to replace the roof
  • you’re making major changes to the layout or size of a property

Removing an old/existing roof
