Cost Breakdown for Professional Roofing Services

When considering professional roofing services with McLellan Contracting, you can expect a comprehensive and educational experience. A roofing expert will meet with you to inspect your current roof, identify any problems, and provide a thorough explanation of the materials used, their benefits, and how they protect your home. This process includes preparing a detailed quotation for your consideration, ensuring you are fully informed and comfortable with every aspect of the project.


Roofing costs can be complex and may seem confusing. To ensure you get an accurate and detailed quotation for your home, we recommend meeting with a professional estimator. They will review the approved procedures and provide a comprehensive quote, including the brand names of all products to be installed.


Material Costs


There are several types of roofing materials, and the cost primarily depends on their properties and durability. Here are some common roofing materials and their costs:

  • Asphalt Shingles: One of the most common and affordable roofing options, costing between $100 and $400 per square (1 square = 100 sq. ft.).

  • Metal: More durable and energy-efficient than many other types, metal roofs cost between $300 and $900 per square.

  • Synthetic Roofing: Mimics the appearance of natural materials such as slate or wood, with costs varying between $400 and $800 per square.

  • Clay or Concrete Tiles: Though durable, these materials can be very heavy, typically costing between $500 and $1,200 per square. * Note: These tiles can only be installed on a roof where the framing has accounted for the extra weight.


Labour Costs


Labour costs are another major component to consider when installing a new roof or replacing an existing one. These costs depend on the complexity of the job, location (local wage rates), and the experience of the roofing contractor. Hiring professional roofing services ensures quality workmanship and efficiency, which can ultimately impact overall costs. On average, labour costs range between $150 and $300 per square.


Additional Costs


Here are some additional roofing costs to consider:

  • Roof Removal: If your project involves removing an existing roof, expect to pay between $100 and $150 per square for removal.

  • Disposal Fee: Contractors may charge $30-$50 per square to dispose of old roofing materials.

  • Roof Deck Repair: Repairing your plywood or plank roof deck will increase the overall replacement cost, between $300-$700 per square.

  • Underlayment and Flashing: Essential for protecting your roof from water damage, costing between $100 and $300 per square.

  • Permits and Inspections: Roofing projects often require permits, which can cost between $150 and $500. * Currently not needed for most shingle re-roofing projects in Ontario, Canada.


Factors Affecting Roofing Costs


Several factors can influence the cost of installing or replacing a roof:

  • Type of Roof: Different roofing materials come with varying costs.

  • Size of the Roof: Larger roofs generally cost more to install or replace.

  • Design Features: Roofs with steep pitches or complex designs are more expensive to install.

  • Location: Local labour rates and material costs can vary significantly. Projects in built up areas add to safety costs to protect adjoining homes and the public.
