## How to calculate timber roof members for building contractor?

I am using approximately 100m. So for 100m, divide by 3.6=28pcs of 3” by 4” or 75mm by 100mm to purchase in the market for timber named wall plate. For FACIAL BOARD, remember the length and breadth of the plan of the building with its overhangs of 0.6m each, so add the perimeter

## How do you calculate the width of timber cladding?
