Materials and Labor: Key Factors That Impact Roofing Cost Estimates

When budgeting for a roofing project, residential or commercial, two significant components will dictate your ultimate price: materials and labor. Both factors are subject to change depending on demand, geography, and the level of job complexity. It is essential that contractors, developers, and homeowners accurately estimate these costs to prevent cost overruns and surprise expenditures.

At Estimate Bees, we specialize in Roofing Estimating Services, ensuring that our clients receive precise and detailed estimates tailored to their project needs. In this blog, we’ll explore how materials and labor impact roofing cost estimates and share insights on how to get the most accurate pricing.

1. Materials: The Backbone of Roofing Costs

1.1 Types of Roofing Materials

The type of roofing material you choose plays a significant role in determining the overall project cost. Here’s a breakdown of popular roofing materials and their price impact:

Roofing MaterialCost Per Square FootDurability
Asphalt Shingles$1.50 – $5.0015-30 years
Metal Roofing$5.00 – $14.0040-70 years
Clay & Concrete Tiles$10.00 – $25.0050+ years
Wood Shingles & Shakes$6.00 – $12.0020-40 years
Slate Roofing$10.00 – $30.0075-100 years
Flat Roofing (EPDM, TPO, PVC)$4.00 – $12.0015-30 years

Choosing the right material depends on your budget, aesthetic preference, and long-term durability expectations. Our Roofing Estimating Services help clients evaluate material options and make cost-effective decisions.

1.2 Material Quality and Grades

Even within the same category, materials come in different grades. For instance:

  • Architectural Asphalt Shingles are more durable and aesthetically pleasing than standard 3-tab shingles but come at a higher price.
  • High-gauge metal roofing lasts longer and resists harsh weather better than thinner metal sheets.

When you use our Construction Estimating Services, we ensure that all material grades are properly assessed to avoid cost surprises.

1.3 Roofing Accessories and Additional Materials

Apart from primary roofing materials, additional materials also contribute to the total cost:

  • Underlayment (Felt or synthetic) – Protects against moisture.
  • Flashing – Prevents leaks at joints and valleys.
  • Fasteners & Adhesives – Essential for securing materials.
  • Insulation & Ventilation – Enhances energy efficiency and extends roof life.

Our Quantity Takeoff Services help contractors account for every component, ensuring accurate budget calculations.

1.4 Transportation and Availability

Material costs vary based on availability and shipping fees. If you’re sourcing imported clay tiles or specialized metal roofing, transportation costs can significantly impact your estimate.

At Estimate Bees, we factor in all logistical costs in our Sitework Estimating Services to ensure full transparency.

2. Labor: The Biggest Variable in Roofing Estimates

2.1 Skilled vs. Unskilled Labor Costs

The complexity of the roofing project determines labor costs. Here’s a breakdown:

Type of LaborCost Per HourBest for
General Roofers$20 – $50Simple shingle installation
Skilled Roofers$50 – $100Metal roofing, slate installation
Specialty Roofers$100+Historical restorations, premium materials

Hiring experienced professionals ensures quality work and reduces long-term maintenance costs.

2.2 Roof Complexity and Labor Hours

Labor costs increase based on:

  • Roof pitch & slope – Steep roofs require more safety measures and labor hours.
  • Number of roof layers – More layers mean longer removal and installation times.
  • Structural reinforcements – If the structure needs extra support, labor costs will rise.

Our Blueprint Estimating Services help identify potential labor challenges before work begins.

2.3 Seasonal and Regional Labor Cost Differences

  • In peak seasons (spring & summer), labor costs rise due to high demand.
  • Labor rates vary by region—urban areas tend to have higher costs than rural locations.

By using our Electrical Estimating Services in conjunction with roofing estimates, we help contractors prepare for all related labor costs.
