For a standard Auckland house with a roof size of approximately 180 square meters, re-roofing using Tab Asphalt Shingles would involve the following associated costs:

  1. Materials: Assuming an average cost of NZD 45 per square meter for asphalt shingles, the total material cost would be approximately NZD 8,100 (180 sqm x NZD 45/sqm).
  1. Labor: Assuming an average labor cost of NZD 100 per square meter, the total labor cost would be around NZD 18,000 (180 sqm x NZD 100/sqm).
  1. Scaffolding: The cost of scaffolding can range from NZD 500 to NZD 2,000 or more, depending on the size and complexity of the project. Let’s assume a scaffolding cost of NZD 1,000.
  1. Additional Materials: The cost of additional materials can vary depending on the specific requirements of the project, but as a rough estimate, it can range from NZD 500 to NZD 2,000. Let’s assume an additional material cost of NZD 1,000.

Based on these estimates, the total cost for re-roofing a standard Auckland house of 180 square meters would be approximately NZD 28,100 (material cost: NZD 8,100 + labor cost: NZD 18,000 + scaffolding cost: NZD 1,000 + additional material cost: NZD 1,000).

For a larger standard Auckland house with a roof size of approximately 220 square meters, the costs would scale accordingly:

  1. Materials: Assuming an average cost of NZD 45 per square meter, the total material cost would be approximately NZD 9,900 (220 sqm x NZD 45/sqm).
  1. Labor: Assuming an average labor cost of NZD 100 per square meter, the total labor cost would be around NZD 22,000 (220 sqm x NZD 100/sqm).
  1. Scaffolding: Assuming a scaffolding cost of NZD 1,000.
  1. Additional Materials: Assuming an additional material cost of NZD 1,000.

Based on these estimates, the total cost for re-roofing a standard Auckland house of 220 square meters would be approximately NZD 34,900 (material cost: NZD 9,900 + labor cost: NZD 22,000 + scaffolding cost: NZD 1,000 + additional material cost: NZD 1,000).

Please note that these cost estimates are rough approximations and can vary depending on various factors, so it’s essential to obtain detailed quotes from roofing contractors to get an accurate cost assessment for your specific project.
