Question

1. what are the implications of a chimney arrangement as shown above? select all that apply. hint: consider the valley. ice damming leakage poor drainage mortar deterioration sheathing rot

Explanation:

1. Ice damming: The valley (where two roof slopes meet) near the chimney can have poor drainage of melting snow, leading to ice buildup (ice damming) as water refreezes.
2. Leakage: Improperly sealed valleys or chimney flashing can allow water to seep through, causing leakage.
3. Poor drainage: The chimney’s position in the valley can disrupt the natural flow of water off the roof, leading to poor drainage.
4. Mortar deterioration: Water infiltration (from leakage or poor drainage) can cause mortar between chimney bricks to deteriorate over time.
5. Sheathing rot: Excess moisture from leakage or poor drainage can penetrate the roof sheathing, causing it to rot.

All these issues are implications of a chimney arrangement in a roof valley due to water management and structural impacts.

Answer:

Ice damming, Leakage, Poor drainage, Mortar deterioration, Sheathing rot
