Shingle Roof Cost Breakdown (2023)

Several factors influence how much a shingle roof will ultimately cost. Here’s what to keep in mind:

1. Roof Size

The overall size of the roof is one of the most significant price factors. Roofs are measured in “roofing squares,” with one square covering 100 square feet. Larger roofs will naturally require more shingles, which increases both the material and labor costs. For example, if your roof is 1,500 square feet (or 15 roofing squares), you will need around 45 bundles of shingles.

2. Choice of Shingle Material

The type of shingles chosen for your roof has a direct impact on the overall price. Common options include:

• Standard Asphalt Shingles: These are the most budget-friendly and typically cost between $80 to $100 per square. For a 1,500 square foot roof, this would amount to about $1,200 to $1,500 for materials.
• Architectural Shingle Roofs: These shingles are layered for added durability and cost more—around $100 to $300 per square. Their longer lifespan and better resistance to weather conditions make them a popular choice for homeowners.
• Metal Shingles: Metal shingles are ideal for areas that experience strong winds or heavy storms. These shingles can range from $325 to $650 per square for aluminum, and $350 to $600 per square for steel.
• Solar Shingles: For those looking to incorporate renewable energy into their roofing, solar shingles are a top choice. They come at a high price—around $2,100 to $2,300 per square—but are eligible for a 30% federal tax credit, making them a worthwhile investment for some homeowners.

3. Roof Shape and Pitch

A roof’s shape and pitch can affect both installation costs and complexity. Roofs with steeper slopes or more intricate designs require extra safety equipment and time. A higher pitch (greater than 33 degrees) makes the roof harder to walk on and increases the likelihood that additional safety measures, like scaffolding, will be needed. This adds both to the time and cost of the project.

4. Labor Costs

Labor costs depend on factors like the roofing contractor’s experience, roof design, and materials. For a precise estimate, always make sure to receive a comprehensive quote from your contractor, detailing labor costs, materials, permits, and cleanup. A reputable contractor will provide a breakdown of these costs to avoid hidden surprises.

5. Additional Costs

Some roofing projects require extra services that can add to the overall expense:

• Licensing and Permits: In California, roofing contractors must have a current C-39 license. Additionally, some regions may require special permits, which could limit the types of materials used or impose other building regulations.
• Removal of Old Shingles: If your roof needs to be replaced, the old shingles must be removed first. The removal process typically costs between $1 and $5 per square foot, depending on how many layers need to be taken off. During this time, the underlying structure will also be inspected.
• Repairs and Reinforcement: If your roof requires repairs or reinforcement before installing new shingles, this can drive up costs. Roof reinforcement might involve adding support beams or columns, which can cost over $1,000 per rafter. Common repairs might include fixing leaks, replacing flashing, or addressing structural damage.
