Rafters / Pitched Roof
The most simplistic method to measure a pitched roof is as followed. Measure the length and the height (Eaves to Ridge) of the internal loft space. Times these two figures together. If your dwelling has two sloping roof sections, multiply this by two.
Example – If the length is 10m, and height is 4.3m:
10m x 4.3m = 43m²
43m² x 2 = 86m²
Total m² = 86m²

Loft Floor / Ceiling Level
The most effective way to measure a ceiling level / loft floor. Take the width of the loft space, then multiply by the length. This will give you the total area.
Example – The length of loft is 8m, and the width is 6m.
8m x 6m = 48m²

Gable End
The most simplistic 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 6m, and height is 3m.
6m x 3m = 18m²
18m² divide by 2 = 9m²

Rafter Centres
How to accurately measure the rafter centers on your roof. Commonly, the centers range between 400mm & 600mm. Start by measuring the left side of one rafter, to the left side of the next rafter along. This method can also be used on Timer Framed Walls & Loft Floor Joists / Ceiling Leve.
