How Much Does It Cost To Replace Roof Tile Underlayment

The Role of Roof Tile Underlayment

Roof tile underlayment is a waterproof or water-resistant barrier that is installed beneath the roof tiles. Its primary functions are to:

  • Prevent water from infiltrating the roof structure and interior of the home.
  • Act as a secondary barrier to protect against wind-driven rain and ice dams.
  • Enhance the thermal efficiency and insulation of the roof.
  • Serve as a temporary weather barrier during roof tile replacement or repair.

Now, let’s delve into the factors that influence the cost of replacing roof tile underlayment:

1. Roof Size

The square footage of your roof is a primary factor that determines the cost of underlayment replacement. A larger roof naturally requires more underlayment material and labor, impacting the overall cost.

2. Roof Slope and Complexity

The slope and complexity of your roof also affect the cost. Steeper roofs are more challenging to work on and may require more time and labor. Additionally, if your roof has multiple dormers, valleys, or other architectural features, the complexity of the job will increase the cost.

3. Underlayment Material

Roof tile underlayment materials come in various types, each with different costs. The most common types include:

  • Felt Underlayment: Asphalt-saturated felt, also known as tar paper, is a traditional and cost-effective underlayment option.
  • Synthetic Underlayment: Synthetic materials like polypropylene or polyester offer enhanced durability and waterproofing. While they are more expensive than felt, they may provide better long-term protection.
  • Rubberized Asphalt Underlayment: These premium underlayments offer superior waterproofing and are often used in areas prone to heavy rain or wind.

The choice of underlayment material will impact the overall cost, with synthetic and rubberized asphalt options being pricier than traditional felt.

4. Labor Costs

Labor costs for underlayment replacement depend on various factors, including the complexity of your roof and the local labor market. Steeper and more complex roofs may require a more experienced and skilled crew, impacting labor costs.

5. Removal of Existing Underlayment

If the existing underlayment needs to be removed before the replacement, this additional step will increase the labor and disposal costs.

6. Repair and Preparation

In some cases, roof deck repairs or preparation may be needed before the new underlayment is installed. These repairs can add to the overall cost.

7. Geographic Location

The cost of roofing projects, including underlayment replacement, can vary significantly by geographic location. Areas with higher costs of living and increased demand for roofing services tend to have higher overall project costs.

8. Permits and Regulations

Local building permits and regulations can also affect the cost. You may need to obtain permits for the work, which can come with associated fees.

9. Roofing Contractor

The roofing contractor you choose will impact the cost of underlayment replacement. Established and reputable contractors may charge higher rates, but they often provide quality workmanship and warranty coverage.

10. Warranty and Quality

The type of underlayment material and quality of workmanship can impact the cost of underlayment replacement. High-quality materials and experienced installers may command a higher price, but they often provide better long-term value.
