Key Cost Factors for Flat Roof Installation

Material Costs

  The type of roofing material you choose will significantly impact the total cost. Some popular options for flat roofs in Santa Ana include:

  • Built-Up Roofing (BUR): Also known as a tar and gravel roof, this traditional option consists of several layers of asphalt or coal-tar pitch with gravel on top. BUR is relatively inexpensive but can be heavy and may require more maintenance.
  • Single-Ply Membranes: These roofing systems are made from synthetic materials such as EPDM, TPO, or PVC and offer excellent durability and weather resistance. However, they tend to be more expensive than BUR.
  • Modified Bitumen: This is an updated version of BUR that combines asphalt with rubber or plastic polymers for added strength and flexibility. It’s a cost-effective choice but may not be as durable as single-ply membranes.
  • Spray Polyurethane Foam (SPF): This eco-friendly option involves spraying a foam layer onto the roof, which then expands and hardens to create a seamless barrier. While it has a higher upfront cost, SPF can offer significant savings on energy bills over time.

Size of the Home

The overall square footage of your roof is one of the most direct factors affecting cost. Larger roofs require more materials and labor, thus increasing the total expense.  Additionally, if your home has multiple levels or complex architectural features, it may require more time and effort to install a flat roof.

Labor Costs

  Labor constitutes a substantial portion of the total cost, often around 60%. For example, if the entire project costs $12,000, expect to pay around $7,200 for labor alone. Labor costs can vary based on:

  • Crew Size: Larger crews may complete the job faster but can be more expensive.
  • Project Duration: The longer it takes to complete the project, the higher the labor costs.
  1. Full vs. Partial Replacement
  • Full Replacement: Removing the old roof and installing a new one can add to labor and disposal costs.
  • Partial Replacement: If only a section of the roof needs replacement, costs will be lower but must be weighed against the potential need for future repairs on the remaining sections.
