The optimal roof slope for a house should be determined based on the type of roofing material used. Therefore, a careful examination of the roofing material is essential before determining the slope of the roof.
Houses in Indonesia is ideal for utilizing a sloping roof model. To ensure proper adjustment of the slope level, it is essential to be familiar with the ideal slope standards. The size of the slope varies for each type of roof.
Have a look at the slope standards for roofs, as well as the perfect size for each type of roof!
How to Calculate the Slope of the Roof
Before looking at the standard slopes of different types of roofing, it is important to understand how to calculate and determine the slope of a roof. Here are the steps!
● Calculating The Length of Half of The Roof
The initial step you can take is to calculate the length of half the roof of your house. Count the number of sides on the roof of your house and then divide the total by two.
For example, if the overall length of one side of the house is 10 meters, then the length that will be used is half of that, which is 5 meters.
● Calculating The Height of The Roof
The next step is to calculate the height of the roof of the house. To calculate the roof slope, you can measure from the ceiling to the highest point on the roof, which is typically in the shape of a hemisphere or acts as a division between sections of the house.
● How to Calculate the Slope of the Roof
The next step involves calculating the roof slope using the Pythagorean formula c2 = b2 + a2, where “a” represents the height of the roof, “b” represents the base of the roof, and “c” represents the slope of the roof.
Roof Slope Standards by Roof Type
Now that you have learned how to calculate the roof slope, it’s time to explore the standard slope sizes for different roof types.
● Zinc Roof
The use of zinc roofs is still widely chosen by the people of Indonesia. Due to its lightweight nature, cost-effectiveness, and ease of installation, zinc roofs remain a preferred option.
However, one disadvantage of zinc roofs is their inability to absorb heat. The recommended slope range for zinc roofs is typically between 15 to 25 degrees.
● Asphalt Roof
There are some houses that use asphalt material as their roof. The advantages of using an asphalt roof are that it is easier to install and it can accommodate a standard slope of up to 90 degrees.
● Concrete Roof
The strength and durability of concrete roofs make them highly popular as a roofing choice for houses.
The concrete roof slope can be adjusted up to 30 degrees. In case you plan to make modifications, you have the flexibility to set the slope at 1% of its length.
● Metal Roof
The use of metal roofs is also quite popular in Indonesia. Because it offers an economical price and can be tilted up to 35 degrees.
● Ceramic Roof
A ceramic roof helps to maintain a cooler temperature within the house. This is due to the characteristic of a ceramic roof that tends to absorb heat more readily. Meanwhile, the slope standard for ceramic roofs can be set to 30 degrees.
● Polycarbonate Roof
If you are considering using a roof made of polycarbonate material, it is important to ensure that the slope is appropriately set to achieve the desired slope angle. While for the standard slope is at the limit of at least 2 degrees.
● Flat Roof
In general, houses that use concrete roofs employ a roof design that is either non-sloping or flat. Hence, for flat roofs, the slope is typically set at 0 degrees, indicating a completely flat roof design.
● Glass Roof
Glass roofs are commonly utilized as protective elements in specific areas of the house rather than being used extensively throughout the entire house. For an ideal size the slope angle of a glass roof ranges from 2 degrees to 90 degrees.
● Spandex Roof
If you intend to use a spandex roof, it is recommended to install it on a slope ranging from 5 to a maximum of 60 degrees.
● Fiber Cement Roofing
Fiber cement roofs with small or large wave designs from Djabesmen are commonly observed as popular choices for houses in Indonesia.
Djabesmen offers an economical, flexible, lightweight, durable, and weather-resistant roof option that can be adjusted to a maximum slop of 20 degrees.
Tips for Installing an Ideal Roof
The installation of a roof should not be done in a disorderly manner or inappropriately. Here are some guidelines for installing a roof that meets the standards and positions the house roof optimally. In order for it to function properly, in other words, to protect the residents of the house.
● Choose the Proper Roofing Type
It is crucial to select a roof that aligns with the overall concept and style of your home. Furthermore, it is important to take into consideration the geographical location and climate of the area where you reside.
In regions with frequent rainfall, it is advisable to opt for a corrugated or sloping roof design with adequate drainage capabilities. One suitable option could be to consider using a fiber cement roof from Djabesmen, known for its durability, water-draining capabilities, and high-quality construction.
● Use Roof Coatings
To enhance the strength of the roof and prevent potential leaks, applying waterproof paint or coating can be a beneficial measure. To achieve the desired aesthetic and functional outcome, selecting a gray fiber cement roof can be a suitable choice.
The neutral color will be easily coated with paint that suits your taste. In addition to enhancing the roof’s durability and functionality, opting for a gray fiber cement roof also adds a pleasing aesthetic touch to your overall roof design.
● Opting for Sloping Roof
Considering Indonesia’s tropical climate, a sloping roof design is highly recommended. Indeed, a sloping roof design not only facilitates efficient rainwater drainage but also promotes improved air circulation.
Using a sloped roof minimizes the risk of standing water on the roof, significantly reducing the risk of roof leakage.
● Adjust The Slope of The Roof According to Its Type
When undertaking a roof installation, it is crucial to carefully consider the recommended slope standards to ensure optimal performance and functionality of the roof.
The first step is to determine the specific type of roof you intend to use, and then proceed with the installation, ensuring that it conforms to the ideal size standards mentioned earlier.
● Installing Eavesthrough
To prevent rainwater from dripping directly around the roof, you can consider installing an eavestrough. By incorporating eavestroughs, rainwater can be collected before it eventually drains down from the roof.
Furthermore, the presence of an eavestrough can also protect your walls from direct splashing of rainwater
