  1. Weather: New Zealand’s weather can be unpredictable and can change quickly, which can make it difficult to schedule and complete a roof replacement project. High winds, heavy rain, and extreme temperatures can all make it difficult to work safely on a roof.
  2. Access: Some roofs may be difficult to access, especially if they are steep or have limited space. This can make it difficult to remove the old roof and install the new one.
  3. Age of the building: Older buildings may have structural issues or may not have been built to modern building codes, which can make it difficult to replace the roof.
  4. Building materials: Some roofing materials, such as asbestos, can be difficult to remove safely and may require specialized equipment and trained professionals.
  5. Budget: Replacing a roof can be a costly project, and it’s important to have a clear understanding of the cost before beginning the project.

What is Asbestos In Your Roof?

In NZ, asbestos was imported and used extensively in a variety of construction related fields, particularly in the manufacture of residential and commercial roofing.

What to do if you have Asbestos in your Roof?

While asbestos is simple to recognise on its own, other elements found in roof tiles make identification more challenging. Asbestos containing roof tiles frequently have a white or grey colour, while many other tiles manufactured of safe materials also have these colours. Although just one in every twenty asbestos containing roof tiles has an identification mark, this is one way to tell whether your roof tiles are asbestos free. You may scientifically test your roof’s tiles to determine whether they contain asbestos.
