Demonstrating Correct Roofing Practices (Model 3)

What happens here

The presenter demonstrates the correct roofing installation methods on a model labeled '3' for 'Right'. This involves first installing an apron (drip edge) with proper nail spacing (8-10 inches, closer for high winds) to protect the eaves. Next, an ice and water shield is installed 2 feet past conditioned spaces, extending up wall intersections and around pipe penetrations for robust waterproofing. Underlayment, specifically 'Roof Runner', is then applied and secured with cap nails. A drip edge is installed over the underlayment along the eaves. Kick-out flashing is properly installed at roof-wall intersections to divert water. A starter course shingle is positioned a half-inch below the apron and nailed at the bottom. Shingles are then installed with proper offset seams, ensuring no seams align. Step flashing is progressively installed up the roof, overlapping shingles and secured with two nails, leaving a small gap for water drainage. Finally, the pipe boot is installed with proper shingle overlap, and sealant is applied only on the top shingle around the pipe to prevent water from pushing back up.

Goal: Show the proper techniques for installing roofing components to prevent leaks.
