In which climate would an internal drain be preferred over a scupper?

• A. Hot climates
• B. Tropical climates
• C. Wet climates
• D. Colder climates

Answer: (D)

Internal drains are favored in colder climates primarily due to their effectiveness in managing the challenges posed by snow and ice. In these environments, water can accumulate on the roof due to melting snow, which can lead to potential drainage issues if not addressed properly. Internal drains reduce the risk of ice dam formation, which can create additional pressure and lead to leaks or structural damage. Utilizing internal drains also prevents water from pooling on the roof surface, which is particularly important in colder climates where the volume of snow can be significant. By directing the meltwater directly to a drainage system within the building, internal drains help maintain the integrity of roofing materials and protect against leakage that can occur when snow and ice melt and refreeze outside. This contrasts with scuppers, which are typically open to the elements and can become blocked or hindered by accumulated snow and ice, making them less reliable in such climates. In summary, in colder climates where snow accumulation and melting are common, internal drains provide a more effective solution for ensuring proper water management compared to scuppers.
