When it comes to roofing, one of the most crucial aspects is determining the correct number of roof tiles per square metre. At Eurostar Roofing, we understand the importance of accurate calculations to ensure a secure and durable roof. In this article, we will provide you with a detailed guide on how to calculate the required number of roof tiles per m2 in Plymouth.

Before we dive into the calculations, it's essential to understand the components involved. Roof tiles are the visible part of the roof, while the underlay is the layer beneath them, providing additional protection against the elements. The type of roof tile and underlay used can affect the calculation, so it's crucial to consider these factors.

To calculate the number of roof tiles required per m2, you'll need to consider the following factors:

• The size of the roof tile (measured in mm)
• The headlap (the overlap between adjacent tiles)
• The gauge (the distance between the centres of adjacent tiles)
  The standard calculation for roof tiles per m2 is:
  Tiles per m2 = (1000 mm / tile length) x (1000 mm / gauge) x (1 / headlap)
  For example, if you're using concrete interlocking tiles with a length of 420 mm, a gauge of 110 mm, and a headlap of 75 mm, the calculation would be:
  Tiles per m2 = (1000 mm / 420 mm) x (1000 mm / 110 mm) x (1 / 0.75) = 21.4 tiles per m2

The required number of roof tiles per m2 can vary depending on the type of tile and the specific requirements of your roof. Here are some approximate values for different types of roof tiles:

• Concrete interlocking tiles: 20-25 tiles per m2
• Clay plain tiles: 25-30 tiles per m2
• Slate tiles: 30-35 tiles per m2

In addition to the roof tiles, you'll also need to consider the scaffolding and timber requirements for your roof. The type and quantity of scaffolding and timber needed will depend on the size and complexity of your roof.

When installing roof tiles, it's essential to follow the manufacturer's instructions and take necessary precautions to ensure a safe and secure installation. This includes using the correct underlay, ensuring adequate ventilation, and following the recommended installation pattern.

Once the roof tiles are installed, it's essential to check that they are securely fastened and evenly spaced. The correct installation of roof tiles is crucial to ensure the longevity and durability of your roof.

Ridge tiles are used to cover the ridge of the roof, and the correct installation of these tiles is essential to ensure a watertight seal. The type and quantity of ridge tiles required will depend on the size and complexity of your roof.
