Final Water Test and Damage Analysis

What happens here

The presenter conducts a final water test across all three roof models, dumping water from a bucket over each to visually compare their performance. The 'Wrong' model leaks extensively, confirming its poor construction. The 'Risky' model shows some underlying moisture, suggesting eventual failure, but still allows water to run off. The 'Right' model remains completely dry underneath, demonstrating the effectiveness of proper installation. Subsequently, the presenter uses a shovel to deconstruct each roof, exposing the underlying materials. This reveals the extent of water penetration and damage (or lack thereof) for each method, emphasizing that while risky shortcuts might last a few years, they will ultimately lead to costly leaks and damage due to poor prep work.

Goal: Visually confirm the effectiveness of proper installation and the damage caused by improper techniques.
