Secure Your Roof With Alpha Builders: Professional Roof Waterproofing Services in Singapore

Roof Waterproofing

Our roofs are specifically built to withstand the elements, and one of the elements it helps protect us from is rain. It’s no secret that rainwater or puddles on our roofs can damage the roofing over time, which translates to extra expenses. Roof waterproofing strives to eliminate these problems by offering an extra layer of protection for our roofs. 

This particular feature is beneficial in countries like Singapore, where the roofing is expected to withstand rapidly changing weather. Singapore is a country that gets hit with rain 167 days a year; that’s why waterproofing is of utmost importance. 

Making our roofs waterproof doesn’t just involve a single component to make it work; it consists of many parts. When these individual parts are correctly installed, the synergy creates the ideal waterproofing scenario. 

Different parts like the gutter, flashing, and the base sheet makes up the waterproofing process. How efficiently these individual parts interact with one another will ultimately dictate how effective the waterproofing is. 

Vital Elements of Roof Waterproofing 

As discussed earlier, waterproofing involves different parts or elements to function correctly. These elements need to do their part properly to contribute to the whole process, which is why proper installation also plays a huge part. 

While these elements cannot function independently, since they are essentially just pieces that make up a roof, they do a great job of deflecting water and protecting your homes when put together. 

Since waterproofing is basically a process and not about a particular product or part, it relies upon the roofing elements that make up the whole. These elements are: 

1. Roofing Base Sheet

A base sheet is what serves as the foundation for the whole structure. This part is made up of waterproof and durable materials like polyester or fibreglass. It is usually topped off with a bitumen asphalt membrane placed on the uppermost layer to reinforce its waterproofing capability. 

2. Underlayment

Roofing underlayment


Roofing underlayment is the layer that rests between the roof shingles and the roof deck. This layer is responsible for absorbing the moisture and the water that sneaks through the shingles, and it is also responsible for protecting the layers below it. 

Customers can pick between felt and synthetic material on which underlayment material to use. Felt is made out of wool and various fibres and can serve as a good waterproofing material because of its absorbent nature. Synthetic underlayment is made out of different polymers and can just as equally repel water from its surface. However, this material is more costly compared to felt. 

3. Flashing

Roof flashing


Roof flashings are basically parts that cover vulnerable areas of your roof. For roofs with chimneys or conjoined sections, there are usually spots where the water can seep in between these two parts, and that’s where roof flashings come in. 

Flashings are usually made up of corrosion-resistant galvanised steel, but there have been different materials for it, like plastic, over the years. Aside from protecting the vulnerable sections of our roofs, these things also allow water to flow more freely on the roof’s surface and not seep between the cracks. 

4. Gutter

The gutter is the final piece that completes the whole waterproofing process. This part drains all the water flowing down from the different parts of the roof, giving them a general direction. Without gutters, water will flow on every side of the roof without a set path to go, creating a messy environment. 

Gutters are basically similar to flashings in many ways, but their positioning sets them apart from flashings. Gutters can be found directly on the foot of the roof, which makes them responsible for draining the water that comes from the top. They also serve as the final destination for the water before being directly sent to the drain.
