Alternatives that can be used as cover the roof is concrete. Concrete form of the roof is flat. There are two types or model that serves as a concrete roof, the conventional concrete and precast concrete.

1. Conventional concrete.
This matter must be known when using concrete as a roof is as follows:
a. The burden of its heavy concrete structures so that necessary security is strong.
b. For the casting process, necessary form work. Materials that can be used as form works are bamboo and wood for the pole and its board or triplex for its holder.
c. Can use for its title the two iron layers with each layer is the distance between 15 - 20 cm. Can also use a mix in light weight steel roof frame.
d.Proses making it takes as long to consider the age of concrete 28 days.

2. Concrete printing.
For printing lighter concrete than conventional concrete. Making it does not require form work so that the time it will not be long compared to conventional concrete and the cost of making it cheaper than conventional concrete.

In making this concrete roof needs to slope the roof. The goal is to be in the water on the surface can still flow. Surface should be coated or waterproofing to prevent leakage due to hot sun and often rain water.
