What is a common risk if rainwater is not properly managed by cladding?

Rainwater management is crucial in building design, particularly when it comes to cladding systems. If rainwater is not properly managed, it can lead to significant issues, including water infiltration and damage. This occurs when water seeps behind the cladding material, leading to problems such as mold growth, rot, and compromised structural integrity of the building materials.

Cladding is designed to protect the underlying structure from the elements, but if gaps, misalignments, or inadequate drainage systems are present, water can penetrate and accumulate. Over time, this moisture can cause serious damage to walls, insulation, and other components of the building, resulting in costly repairs and reduced lifespan of the structure.

Other options, while potentially relevant in broader contexts, do not directly address the immediate risks associated with poor rainwater management. Increased heating costs may arise from other factors, beautification is a separate concern often related to aesthetics rather than functionality, and overheating typically relates to poor insulation or ventilation rather than water management issues.
