The Layered Approach to Roof Construction

At Blue Collar Roofers, we believe in educating our customers about the intricacies of roofing systems. Today, we’ll delve into the technical details of a modern roofing system’s anatomy, exploring how each layer contributes to the overall protection and efficiency of your home.

1. Roof Decking

The foundation of any roofing system is the decking, typically made of plywood or oriented strand board (OSB). This layer provides structural support and serves as the base for all subsequent layers.

2. Underlayment

Applied directly over the decking, the underlayment acts as a secondary water barrier. Common types include:

  • Felt paper (traditional)
  • Synthetic underlayment (modern, more durable)
  • Rubberized asphalt (for enhanced water resistance)

3. Ice and Water Shield

In areas prone to ice dams, such as Syracuse, NY, and surrounding regions, an ice and water shield is crucial. This self-adhering membrane is applied along eaves, valleys, and other vulnerable areas to prevent water infiltration.

4. Starter Shingles

These specialized shingles are installed along the roof’s edges to provide a clean, straight line and enhanced wind resistance.

5. Shingles or Primary Roofing Material

The visible layer of your roof, which can be asphalt shingles, metal panels, tiles, or other materials, depending on your preference and local climate conditions.

6. Ridge Capping

Special shingles or materials used to cover the peak of the roof, providing a finished look and additional protection against water infiltration at these vulnerable points.

7. Ventilation System

Proper attic ventilation is crucial for maintaining a healthy roofing system. This includes:

  • Soffit vents
  • Ridge vents
  • Gable vents (in some cases)

Understanding these components helps homeowners in Fairmount, Salina, Dewitt, Clay, and Cicero, NY, appreciate the complexity of a well-constructed roof. At Blue Collar Roofers, we ensure each layer is properly installed to maximize your roof’s lifespan and performance.
