Here are the Reasons Why Roofs Are Made with Corrugations

Sep 22, 2023

Have you ever pondered why the majority of house roofs feature a corrugated design? In essence, there are multiple functional and durability-driven factors contributing to this corrugated design.

This is precisely why corrugated roofing offer numerous advantages, making them a wise choice for many. So, delve into the rationale behind this distinctive form and its associated benefits in this review.

Why Are Roofs Made with Corrugations?

Roofs featuring a corrugated design have gained significant popularity in the realms of architecture and construction. Below, we explore various reasons why corrugated roofs have garnered widespread appeal:

  1. Enhancing Structural Resilience

One of the primary motivations behind the utilization of corrugated roofing is to bestow remarkable structural strength upon roofs. The introduction of these corrugated waves adds an extra layer of sturdiness and rigidity that proves invaluable in the realm of construction.

These corrugations endow roofs with increased resistance against external pressures and the burdens imposed by factors like heavy rainfall during extreme weather conditions.

Moreover, their structural robustness renders this roofing style better equipped to withstand strong winds and turbulent storms. The undulating shape serves to alleviate wind pressures that could otherwise compromise the integrity of a flat roof.

In essence, the corrugated configuration reinforces the uppermost portion of a structure, enhancing its capacity to support the overall structural load. This is precisely why corrugated roofs are renowned for their durability and longevity when compared to their flat counterparts.

  1. Efficient Rainwater Drainage

Another reason behind the making of roofs with corrugations is to assist in the efficient drainage of rainwater. The curved or corrugated shape serves as a channel for rainwater to flow into the gutters or yard.

This means that rainwater can be quickly directed away from the roof's surface, minimizing the risk of pooling. This is crucial because pooled water can lead to serious issues such as leaks, cracks, or structural damage to buildings.

Furthermore, inefficient drainage of rainwater can also promote the growth of mold and moss due to the damp conditions. This can cause the building's structure to deteriorate and become more vulnerable.

Therefore, wave-shaped roofs should be installed with a minimum slope of 5 degrees to ensure smooth water flow. This is one of the reasons why many homes in tropical climates with frequent rainfall opt for corrugated roofs.

  1. Preventing Rainwater Infiltration

In addition to facilitating rainwater drainage, another reason for using roofs with corrugations is to prevent rainwater from infiltrating the interior of homes or buildings.

This is achieved through specific openings strategically placed at the peaks of the waves. These openings are designed to ensure that rainwater cannot penetrate the roof and seep into the interior.

By doing so, the risk of roof leaks can be significantly minimized. This is of utmost importance because roof leaks can lead to severe damage to the interior areas of a building. 

  1. Sound Dampening Capability

A frequent challenge for homeowners is the intrusive noise of heavy rainfall. The loud pattering of raindrops can disrupt indoor activities.

On the flip side, corrugated roofs possess the ability to effectively dampen rain sounds. The undulating patterns on these roofs can impede the rain's noise, making it less audible inside the house.

As a result, this design can contribute to a quieter and more comfortable indoor environment. This is one of the reasons why roofs with corrugations are favored by many.

  1. Enhancing Healthy Airflow

Additionally, wave-shaped roofs play a role in promoting healthy airflow within your home. Proper airflow keeps your living space feeling fresh and helps eliminate stuffy odors.

Furthermore, corrugated roofs aid in maintaining a pleasantly cool indoor environment. This is due to their unique design that provides protection against excessive sunlight and heat.

With a consistently cool, refreshing, and well-ventilated interior, your indoor activities become far more comfortable. Hence, wave-shaped roofs prove to be a practical choice for residences in hot tropical climates like Indonesia.

  1. Aesthetic Appeal

In addition to its functional advantages, wave-shaped roofs also offer an appealing aesthetic. Many people find that corrugated roofs exude more elegance and charm compared to flat roofs.

This is because the undulating waves on the roof create a dynamic and captivating visual effect. Moreover, corrugated roofing sheets are available in a variety of colors, including red, green, brown, black, and more.

This means you can choose the roof's color and design to match the building or its surroundings. This aesthetic factor makes it suitable for various types of structures, be it residential homes, commercial buildings, or even industrial facilities.

  1. Design Flexibility

Another reason to opt for roofs with corrugations is their ability to offer greater flexibility in architectural design. The existing waves can be utilized to create designs that appear more unique and appealing.

In fact, you can combine various levels of different waves or blend them with flat roofs to create a more dynamic appearance.

This is why wave-shaped roof designs can be used to produce a variety of captivating visual effects. This design flexibility makes wave-shaped roofs highly suitable for various types of buildings, especially residential homes.

  1. Swift Installation and Cost-Effectiveness

Lastly, wave-shaped roofs offer benefits such as faster installation and cost efficiency. This is because installing corrugated roofs is relatively straightforward and doesn't require specialized skills.

Furthermore, corrugated roofing sheets can often be installed on top of existing roofs, allowing you to save on the expenses associated with a complete roof replacement. You only need to adjust the number of roofing sheets based on your requirements.

With budget-friendly prices and economical installation, corrugated roofs are a smart and cost-effective choice. This makes them well-suited for construction projects, especially for homes or buildings with limited budgets.

Varieties of Corrugated Roofing Materials

After discovering the reason behind the making of roofs with corrugations, it's important to also explore the typical choices for materials employed in corrugated roofing. Notably, not every material can be fashioned into a corrugated roof.

Here are several common options for materials utilized in corrugated roofing across different structures:

  • Metal Roofing

As implied by its name, this roofing type is crafted from metals like aluminum, iron, or steel, which are molded to shape. Despite being lightweight, it's worth noting that this material is more susceptible to rust due to corrosive reactions.

  • Clay Tiles

Crafted from clay, these tiles are immune to rust. However, they tend to be heavier, fragile, and have the potential to foster mold and moss growth.

  • Fiber Cement Roofing

The primary constituent of this roofing type is fiber cement, reinforced with synthetic fibers. Consequently, fiber cement roofs boast greater durability, strength, resistance to extreme weather conditions, corrosion resistance, and are less prone to mold and moss development.

The various reasons mentioned in the above review for opting for roofs with corrugations highlight numerous advantages of this roofing style that you should consider. However, make sure to choose a corrugated roof crafted from top-tier, high-quality materials.
