Steep-slope roofs are typically preferred in regions prone to heavy rains for several reasons related to their design and functionality. The steep angle of these roofs allows rainwater to flow off more rapidly, reducing the risk of water pooling or standing on the roof surface. This is particularly important in areas that experience heavy rainfall, as standing water can compromise the integrity of the roof over time and increase the likelihood of leaks or other water damage.

Additionally, steep-slope roofs are often constructed with materials that enhance their durability and water resistance, such as shingles or metal panels, which can better handle the force of rain and prevent water infiltration. This design minimizes the chances of the roof system failing during heavy rain events.

In contrast, flat roofs and low-slope roofs may not provide adequate drainage, leading to potential water accumulation and associated issues. These roof types may be more suitable in drier climates or areas with a lower risk of heavy rainfall. Therefore, the choice of a steep-slope roof is a strategic decision to enhance building resilience against severe weather conditions, particularly in regions with significant precipitation.
