What happens here
The video introduces the first roof model, labeled '1' for 'Wrong', demonstrating several critical errors in roofing installation. The presenter shows a bucket of water being poured over the roof, immediately resulting in significant leaks. He highlights that there is no underlayment, shingles are installed directly, and seams are improperly aligned allowing water penetration. The starter course is omitted, and step flashing is neglected, replaced by caulk at wall intersections. The pipe boot is also incorrectly installed, relying on caulk and extra nails in problematic areas, allowing water to easily run behind the flashing and lead to leaks.
Goal: Show how common roofing mistakes lead to immediate leaks.
