Gaps in Roof Tile Corners: Do They Need Cement Sealing in Koh Samui?

If you are currently building or maintaining a home in Koh Samui, you might notice small gaps between the corner roof tiles and the bargeboards (as shown in the image). A common question homeowners ask is: "Should the contractor seal these gaps with cement?" In the harsh tropical environment of Koh Samui, getting this right is crucial for the longevity of your property.

At CHK Structure and Service Co., Ltd., with over 10 years of experience in Koh Samui, we have seen how small oversights in roofing can lead to major headaches later.

Why Roof Gaps are a Major Risk in Koh Samui’s Climate

Koh Samui is famous for its beautiful weather, but for a house, it means dealing with intense UV rays, salty sea air, and heavy monsoon rains. Leaving roof gaps untreated can cause several issues:

Potential Hazards of Open Roof Gaps

  1. Water Infiltration: During the monsoon season in Koh Samui, wind-driven rain can easily push water upward through these gaps, leading to ceiling leaks.

  2. Pest Infestation: Birds, rats, and even snakes often use these gaps to enter the attic space.

  3. Structural Damage: Constant moisture entering through the roof can rot wooden battens and damage the concrete structure over time.

To Seal or Not to Seal? The Expert Answer

The short answer is: Yes, these gaps must be sealed, but traditional cement (Wet System) might not always be the best solution for homes in Koh Samui.

Modern Solutions for Sealing Roof Gaps

  • 1. Dry Tech System: Using high-quality flashing tapes and specialized roof coverings is the most effective way to handle the heat and humidity of Koh Samui.

  • 2. PU Sealant: For smaller gaps, high-elasticity Polyurethane (PU) sealants are superior to cement because they don't crack when the house settles or during temperature changes.

  • 3. Mortar with Waterproofing Additives: If cement must be used, it must be mixed with professional-grade waterproofing agents to prevent the "sponge effect" that absorbs moisture.
