5 Roof Design Problems to Watch Out For

02 July 2022

A proper roof is not defined by its beauty, but rather its ability to protect the house from sunlight and rain effectively. The beautiful feature should be considered together when designing, so that you can apply the roof design which matches your style to your house.


In the rainy season, many people may face roof leakage problems. Climbing on the roof to fix the problem is not an easy thing to do and may need a skilled technician to do the job for you. The roof is considered as one of the important parts of the house, so it should not be ignored. We will be discussing further on the common mistakes to avoid usually caused by design and can result to roof leakage problems.


1. Too Much Combination of Roof Design

Normally, there are six (6) different kinds of roof designs consisting of standardized gable roof, gable hip roof, hip roof, lean-to/shed roof, flat roof, and curved roof. Although designing the roof by combining many types of roof designs may help make your home look more interesting, it unavoidably increases more seams between the roof structures which can cause roof leakage problems.


2. Using a Slab Roof

Although every type of roof can leak, a flat roof (Slab Roof) is the most likely to leak. If you wish to use a flat roof, it is recommended to pay particular attention to certain points, such as the seams between the roof and the beam, incorrect method of concrete casting which can also cause cracks and leakage on the roof, or even drainage and air duct drilling which may lead to leakage problems as well.


3. Slope of the Roof

A roof whose slope is not steep enough or unsuitable for the type of roof tiles used often causes leakage from the wind that blows the rain through the roof, and with the unsuitable slope of the roof, it may lead to malfunction of drainage and leakage protection. In this regard, normal roofs should have a slope of 30-45 degrees, but for SCG Concrete Roof tiles, it must have a slope of at least 25 degrees.


4. Fragile Structure

Choosing to use the roof structures which do not meet the required standard may lead to roof deflection problems that will, in turn, move the tiles and cause leakage problems. As a result, the roof structure may need to be repaired prematurely.


5. Seams and Cracks

Steel-reinforced concrete components may crack due to improper concrete casting and non-standard steel reinforcement processes, such as flashing and cement fin. Besides adding steel for pulling reinforcement, proper concrete casting will reduce the risk of cracks and leakage problems.

Now that we know the roof designing which may cause leakage problems, in the future when we need to design our roof for our house, we should be careful and regularly check and inspect the construction of our roof in order to prevent the problems that may follow.
