Roof Pitch and Design

The longevity of a roof is influenced by several factors, including the roof slope and architectural design. One key consideration is the choice between pitched roofs and flat roofs.

Pitched roofs, with their sloping design, are known for their ability to shed water and debris more effectively. This helps prevent water pooling and reduces the risk of leaks or structural damage. The steeper the pitch of the roof, the better its ability to shed water. Additionally, pitched roofs provide better ventilation, which can help prevent moisture buildup and prolong the life of roofing materials.

On the other hand, flat roofs have a horizontal or low-slope design. While they offer certain advantages such as easier access for maintenance and installation of equipment like HVAC units or solar panels, they are more prone to water pooling. Without proper drainage systems in place, flat roofs can experience water infiltration over time leading to leaks and potential damage.
