New Roof Decking Costs: A Comprehensive Guide

Roof decking, also known as sheathing, is a vital component of your roofing system. It acts as the base for roofing materials and ensures structural integrity. When it’s time for a replacement, understanding the costs involved helps you make informed decisions. Select Pro Contracting, located in Plymouth, MA, provides expert services to homeowners, ensuring high-quality installations tailored to your needs.

What Is Roof Decking and Why Is It Important?

Roof decking is the foundation of your roof, typically made of plywood or oriented strand board (OSB). It supports shingles, distributes weight evenly, and insulates your home. Over time, exposure to moisture, age, and weather conditions can weaken this essential layer.

Benefits of Quality Roof Decking:

• Provides a stable base for roofing materials.
• Enhances structural integrity.
• Acts as a barrier against moisture and wind.
• Improves energy efficiency by aiding insulation.

Average Costs for New Roof Decking

The cost of new roof decking varies based on material, labor, and roof size. Here’s an overview:

• Inspection Costs: $100–$400.
• Material Costs: $0.30–$2.60 per square foot.
  • Plywood: Durable but heavier, $0.50–$2.00 per square foot.
  • OSB: Cost-effective but less moisture-resistant, $0.30–$1.80 per square foot.
  • Tongue and Groove: Premium option for added strength, $1.50–$2.60 per square foot.
• Labor Costs: $1.50–$3.00 per square foot, depending on the complexity of the job.

Fun Fact: Properly installed roof decking can extend the lifespan of your roof by up to 25 years, depending on materials and maintenance.

Factors Influencing Roof Decking Costs

Roof Size

Larger roofs require more materials and labor, driving up costs. For example:

• 1,000 sq ft roof: $2,000–$5,000
• 2,000 sq ft roof: $4,000–$10,000
• 3,000 sq ft roof: $6,000–$15,000

Roof Complexity

Steep slopes, valleys, and architectural details increase labor time and costs. Complex designs may also require specialized materials or techniques.

Local Labor Rates

In Massachusetts, roofing labor costs range from $45 to $75 per hour. Total costs depend on the project’s size and duration.

Material Selection

High-quality materials like tongue and groove cost more but provide added durability and support, especially for heavy roofing systems like slate or tile.

Signs Your Roof Decking Needs Replacement

• Frequent Leaks: Persistent water stains or mold indicate underlying issues.
