The Importance of Correct Spandek Roof Slope

Spandek roofs have various advantages, including high durability and ease of installation. However, without the appropriate slope, the roof can experience problems such as puddles and leaks. The following are the reasons why the slope angle of the spandek roof must be correct.


1. Prevent Water Puddles

One of the main reasons why the slope angle of the spandek roof is important is to facilitate the flow of rainwater. A spandek roof that is too flat is at risk of causing puddles, which in the long term can cause rust, leaks, and even structural damage to the roof itself.


2. Withstand Wind Pressure

A spandek roof that is too steep or too sloping can affect stability when exposed to strong wind pressure. Spandek installed at an ideal slope will have a balance in terms of resistance to wind pressure without causing excessive pressure on the roof frame.


3. Material and Cost Efficiency

The correct slope of the spandek roof can save the use of supporting materials such as battens, trusses, and joints. This has a direct effect on the efficiency of installation costs.

4. Building Aesthetics

The slope of the spandek roof also has aesthetic value. A slope that is too steep can make a house look like an industrial warehouse, while too flat can reduce the impression of solidity in the building design. Spandek roofs installed at an ideal angle will look proportional and modern.


Determining the right slope of the spandek roof is very important to ensure that the house is safe, durable, and free from leakage problems. Hopefully useful.
