Hey there! If you're like me, a PC roof tile supplier, you've probably heard some complaints from customers about the noise that PC roof tiles make during rain. It can be quite a nuisance, right? Well, in this blog post, I'm going to share some tips on how to reduce that annoying noise.
First off, let's understand why PC roof tiles make noise when it rains. PC, or polycarbonate, is a hard and smooth material. When raindrops hit it, they create vibrations that travel through the tile and into the building, causing that loud drumming sound. But don't worry, there are ways to tackle this issue.
1. Insulation is Key
One of the most effective ways to reduce noise from PC roof tiles is by adding insulation. Insulation acts as a buffer between the rain and the interior of the building, absorbing the vibrations and reducing the noise. There are different types of insulation materials you can use.
- Foam Insulation: This is a popular choice because it's lightweight and easy to install. You can find foam insulation in rolls or sheets. Just cut it to the right size and attach it to the underside of the PC roof tiles. It works by trapping air pockets, which helps to dampen the sound.
- Fiberglass Insulation: Fiberglass is another great option. It's known for its excellent sound - absorbing properties. However, it requires a bit more care during installation as the fibers can be irritating to the skin and lungs. Make sure to wear protective gear when handling it.
2. Use Underlayment
Underlayment is a layer that goes between the PC roof tiles and the roof structure. It can significantly reduce noise. There are different types of underlayment materials available.
- Rubber Underlayment: Rubber is a soft and flexible material that can absorb a lot of the impact from raindrops. It also provides some waterproofing benefits. You can buy rubber underlayment in rolls and lay it down before installing the PC roof tiles.
- Cork Underlayment: Cork is a natural material that has good sound - insulating properties. It's also eco - friendly. Cork underlayment comes in sheets and can be easily glued to the roof structure.
3. Change the Installation Method
The way you install the PC roof tiles can also affect the noise level.
- Stagger the Tiles: Instead of installing the PC roof tiles in a straight line, stagger them. This changes the way the raindrops hit the tiles, reducing the resonance and noise. When you stagger the tiles, the raindrops don't hit all the tiles at the same time, which helps to break up the sound.
- Use Gaskets: Gaskets are small rubber or foam strips that you can place between the tiles and the roof structure. They help to create a seal and reduce the vibrations that cause noise. You can find gaskets in different sizes and shapes at your local hardware store.
4. Choose the Right Tile Thickness
Thicker PC roof tiles tend to make less noise than thinner ones. When the tile is thicker, it has more mass, which means it can better absorb the impact of the raindrops. If noise reduction is a priority for your customers, recommend thicker tiles.


5. Maintenance
Regular maintenance of the PC roof tiles can also help to reduce noise.
- Clean the Tiles: Over time, dirt and debris can build up on the PC roof tiles. This can change the way the raindrops hit the tiles and increase the noise. Clean the tiles regularly with a mild detergent and water to keep them in good condition.
- Check for Damage: Cracked or damaged tiles can make more noise than intact ones. Inspect the tiles regularly and replace any that are damaged.
