Roof demolition is an important step in any major renovation project or complete roof replacement. Whether it’s to remove a damaged roof, prepare for adding a new level, or replace an aging structure, this operation must be carried out methodically, expertly, and in compliance with safety standards.

At Duro-Toit, we support residential and commercial property owners throughout their roof demolition and replacement projects, from initial diagnosis to full restoration.

What Is Roof Demolition?

As the name suggests, roof demolition involves removing all or part of the existing roofing, including sometimes the roof structure (rafters, beams, joists), to allow for reconstruction or the installation of a new roofing system. This intervention can apply to various types of roofs, whether flat, sloped, asphalt shingles, metal, or other materials.

Why Consider Roof Demolition?

Here are the most common situations justifying a complete or partial demolition:

  • Severely damaged roof: significant leaks, mold, or weakened structural components.
  • Complete roof replacement: during major renovations or building transformations.
  • Changing roof type: transitioning from asphalt shingles to metal roofing or altering the roof slope.
  • Adding a floor or extension: requiring the removal of the existing roof for reconstruction.
  • Construction standards: meeting updated safety, insulation, or structural requirements.

A Complex Operation Requiring Expertise

Unlike simple roof repairs, roof demolition requires thorough planning, specialized equipment, and skilled labor. There are multiple risks involved, including falling materials, structural instability, exposure to the elements, and hazardous waste such as asbestos in older buildings.

Typical Steps in a Roof Demolition Project

  • Inspection and assessment: evaluating the roof’s condition and deciding on the approach (partial or complete).
  • Site preparation: securing the area, scaffolding setup, protecting interiors.
  • Removal of materials: taking off shingles, membranes, insulation, and structural elements if needed.
  • Waste management: transporting debris to authorized sorting or treatment centers.
  • Preparation for the new roof: cleaning, installing new materials, insulation, waterproofing.

How Much Does Roof Demolition Cost?

  • Type of roofing (shingles, metal, elastomeric membrane…)
  • Roof accessibility (height, slope, obstacles)
  • Structural complexity
  • Time required for removal and cleanup
  • Potential hazardous materials (asbestos, tar)

On average, roof demolition costs range from $6 to $15 per square foot, depending on project specifics.
