Understanding Roof Decking and Sheathing
OSB vs. Plywood in Roof Construction
Roof decking, also known as sheathing, forms the foundation of your roof system. The two primary materials used are OSB (Oriented Strand Board) and plywood, each with unique characteristics. OSB is favored for its cost-effectiveness and strength, but may sag over time if joists are spaced wider than standard. Plywood, on the other hand, offers a more robust structure due to its layered veneer construction, making it less prone to warping.
The Rise of Zip System Roof Panels
A newer addition to the roofing market, Zip System roof panels offer an integrated water-resistant barrier, eliminating the need for additional waterproofing layers. This option is particularly beneficial in wet climates, though it’s crucial to ensure proper installation to avoid leaks.
The Role of Drip Edge in Roofing
Benefits and Installation of Drip Edges
Drip edges, typically made of galvanized steel, aluminum, or copper, are installed along the roof’s perimeter. They serve multiple purposes, including directing water away from the fascia and enhancing the roof’s aesthetic appeal. Available in various widths, they cater to different roofing systems and are now a standard code requirement in many areas.
