Choose a wooden roof or lightweight steel roofing
Minimalist roof is part of building a home that always we find in any home building. Be it a tile roof that uses wood frame, steel, or a flat roof using concrete. In essence, the roof is the very top of the building that provides protection against weather bottom, heat, rain and sun.
Choose whichever wooden roof construction or mild steel applications for your roof? Each has advantages and disadvantages in terms of both quality and cost budgets. The use of wood construction on the roof of the house had long passed down from a common ancestor majapahit until now proved that the use of wood and bamboo to build houses
Here are some more specialized function roof:
1. Receive load by the weight of its own, that the burden of horses and vertical directional coating materials and then pass them on to the column and foundation
2. Resist wind pressure load on the horizontal directional gavel
3. Receiving the hot sun and withstand temperatures to keep them cool in the attic and absorbs the heat in tropical architecture concept
4. Avoid the entry of rainwater
Roofs that are commonly found in houses in Indonesia is the roof with wooden construction. Lately, rampant provider roof made of lightweight steel construction. Both the roof construction wood and mild steel has disadvantages and advantages on their own. Comparisons using wooden roof and steel, among others:
ROOF CONSTRUCTION WOOD
advantages:
1. The roof of wooden construction still attracts many
2. Is a material that is easy to get anywhere in stores material
3. merupan building materials that are controlled by the local artisan
4. wood materials can be shaped, cut and used flexibly (it can be measured, cut, shaped curve and so on)
The drawback:
1. The wooden roof is flammable and can be eaten by termites
2. The wood material can expand or shrink
3. Expanding the roof with wooden construction is often limited because of the size of the timber on the market is 4 meters
4. Timber increasingly difficult to obtain as a result the price is more expensive
LIGHTWEIGHT STEEL ROOF
advantages:
1. It is a new material that is increasingly in demand
2. The material can be made with a variety of stretch (length or width of the roof)
3. It is a substance that when designed properly, will be stronger dati wooden roof as well as more secure

Direct manufacturing energy needs manufacture of wood products require much less energy than the input-process steel. Most of the wood stored energy from the solar energy produced by photosynthesis. Wood grows, it converts carbon dioxide into oxygen, during the process of photosynthesis, storing carbon even in a state produced. The use of timber yields lower CO2 emissions than others.
On the issue of sustainability, steel seems to have a clear advantage in the depletion of raw material resources, while the difference in energy use between wood and steel do not have significant differences, if modifications to the design because the high strength of steel included in the calculation of the sustainability cycle.
