Roof Designs Suitable for Rainy Areas

High rainfall is a major challenge in home design, especially in tropical regions like Indonesia. The following are popular roof designs in Indonesia and are most suitable for rainy areas.


1. Sloping Roof with Ideal Slope

One recommended roof design is a sloping roof with a minimum slope of 30 degrees. This design allows rainwater to drain quickly into the drain without being retained, preventing it from accumulating and seeping into the house.


2. Combination Roof with Hidden Gutters

Use a roof system with hidden gutters within the overhang structure. In addition to creating a neater facade, rainwater can be directly discharged through pipes to the infiltration or drainage system.


3. Combination Overhang and Canopy

For areas such as terraces or large windows, overhangs can be combined with canopies made of polycarbonate or tempered glass. This not only adds protection from rain but also allows natural light to enter the room.


These three roof designs are the best choices because they are considered capable of draining rainwater quickly so that it does not burden the roof and cause leaks. In the long term, your home will be more durable, comfortable, and have minimal maintenance costs.
