In old-time people preferred constructing structures using wood or steel but the wood was mostly used. We generally use the time for construction. Constructing roofs using wood has been on increasing demand rather than decreasing because wood is like any other matter strong that can easily withstand pressure, lightweight which will put minimum pressure on the structure like a shade that is built. The interesting fact is that timber is a renewable resource that we can produce by taking good care of our timber growing trees.
