Pitched Roof / Rafters

The easiest way to measure a pitched roof is as followed. Measure the length and the height (Eaves to Ridge) of the internal loft space. Multiply these figures together. If your home has two sloping roof sections, multiply this by two.

Example – If the length is 8m, and height is 4.3m:
8m x 4.3m = 34.4m²
34.4m² x 2 = 68.8m²
Total m² = 68.8m²

Loft Floor Joists

The most effective way to measure a loft floor. Take the length of the loft space, then multiply by the width to calculate the area.

Example – The length of loft is 6.2m, and the width is 4m.
6.2m x 4m = 24.8m²

Gable End

The most effective way to measure a Gable End. Firstly measure the width along the loft floor. Then measure the height of the wall, from the loft floor to the ridge. Then multiply these measurements together, and finally divide by two.

Example – Loft floor width is 3.5m, and height is 4m.
3.5m x 4m = 14m²
14m² divide by 2 = 7m²
