The Advantages of GRC Board as a Roof Overhang Material in Tropical Climates

A roof overhang is an extension of the roof that protrudes beyond the wall. Its function is to protect exterior walls from rain splashes, minimize the amount of sunlight entering the room, and serve as an aesthetic element of the home. In this context, a material is needed that can withstand UV exposure, heavy rain, and daily temperature fluctuations.

One material suitable for roof overhang applications is GRC board. The base material of GRC board is cement that has undergone pressing and durability testing as a building construction material. Its denser structure provides GRC board with extra strength. When heavy rain flows over the GRC board roof overhang, the water will run off and dry without damaging the board’s structure. Additionally, the material is mold-resistant, termite-resistant, and weather-resistant. This contrasts with some other materials that may experience delamination when used in weather-exposed areas.

Aesthetically, GRC boards used as roof overhangs come in a variety of designs. These range from standard roof overhang types with a smooth surface to those with textured surfaces resembling wood grain details. An example is the 8 mm thick x 200 mm wide x 3000 mm long GRC Ecoline Mahogany.

GRC boards are a suitable and recommended choice for roof overhang applications, particularly in tropical climates. Their advantages including resistance to rain exposure, UV resistance, fire resistance, mold resistance, and ease of finishing make GRC boards a long-term investment for building owners. So, consider using GRC boards as the primary material for your next construction or renovation project.
