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.

Roof Underlayments: Types and Functions

Comparing Felt Paper and Synthetic Underlayments

Roof underlayments, invisible post-shingle installation, play a crucial role in waterproofing. Felt paper, the traditional choice, is budget-friendly but prone to tearing and water absorption. Synthetic underlayments, made from polypropylene or polyethylene, offer superior strength, moisture resistance, and safety during installation.

Ice & Water Shield: An Essential Layer

The Ice & Water Shield, a rubberized asphalt underlayment, provides exceptional waterproofing, especially on low-slope roofs. It’s self-adhering, ensuring a secure seal around nail heads and critical roof areas.

Navigating the World of Roofing Nails

Selecting the Right Nails for Your Roof

Roofing nails, primarily made of galvanized steel, are crucial for securing shingles. In coastal or rainy areas, stainless steel nails are recommended to prevent rust. For ridge vents, ring shank nails offer better security against wind uplift.

Diverse Roof Shingle Options

Understanding 3 Tab, Architectural, and Designer Shingles

Shingles are categorized into 3 tab, architectural, and designer types. 3 tab shingles are economical but offer a basic look and lower wind resistance. Architectural shingles provide a dimensional appearance with better durability and wind resistance. Designer shingles, the premium choice, mimic slate or wood shakes and offer the highest level of aesthetics and performance.

Flashing: A Critical Component for Leak Prevention

Types and Importance of Roof Flashing

Flashing, though often unseen, is vital for preventing water intrusion. Types include step flashing, wall flash
