Roofing Cost 

1. Materials (Shingles)

 - Asphalt Shingles: These are the most common and cost-effective roofing material.

Basic asphalt shingles typically cost between $90 to $150 per square (100 square feet). However, higher-end versions, like architectural or dimensional shingles, can be more expensive.

 - Fiberglass Composite Shingles: Fiberglass shingles are a type of asphalt shingle, but they are made with a fiberglass mat to improve durability and weather resistance. They can cost anywhere from $120 to $180 per square, depending on the quality and brand. High-quality fiberglass shingles, like those with a higher wind resistance or energy efficiency, can be on the higher end of the price spectrum.

2 Labor Costs: 

Labor typically makes up a significant portion of the total cost of a roof replacement. In Michigan, the average labor cost for roof installation ranges from $150 to $300 per square. This cost can vary depending on the roofing company, the experience of the crew, and the region within Michigan. Urban areas like Detroit or Grand Rapids might have slightly higher labor costs compared to rural areas.

3. Roof Complexity:

The complexity of the roof can impact the overall cost. For instance:

- Roof Pitch:  

A steep roof will require more labor and safety measures, leading to higher costs. Roofs with multiple peaks, valleys, or intricate designs will take longer to install.

- Roof Size: 

While you're looking at a 22-square roof, the size may also differ due to additional features, like chimneys, skylights, or ventilation systems, which require extra labor and materials.

In general, if your roof has multiple stories or requires extensive work (like replacing damaged decking), you might see an increase in labor costs.

4.  Removal of Old Roofing: 

Roof replacement generally includes tearing off the old shingles, which can add $1 to $3 per square foot to the total cost. For a 22-square roof, that could add $2,200 to $6,600, depending on the condition of the old roof and the difficulty of removal. If your old roof has multiple layers, that could increase the cost further.

5. Additional Costs: 

- Underlayment: Underlayment is the protective layer beneath the shingles, which helps with water resistance. A typical asphalt roofing underlayment can cost between $0.30 to $0.75 per square foot, adding another $660 to $1,650.

 - Flashing and Vents: Flashing around chimneys, vents, and other roof penetrations is essential to ensure proper water runoff. Flashing and vents can cost between $300 to $800 depending on the number and type of penetrations.

- Permits: Depending on local regulations, you may need to obtain a permit for the roof replacement, which could cost $100 to $400.

6. Geographic Location in Michigan:

 - Urban Areas: In larger cities like Detroit, Grand Rapids, or Lansing, labor rates and material costs might be slightly higher compared to rural areas due to higher demand and cost of living.

 - Weather Conditions: Michigan’s harsh winters can impact the timing of roofing projects. Contractors may raise prices for winter installations due to challenges with weather conditions, such as snow, ice, and cold temperatures.

7. Warranty and Quality:

 - Shingle Warranty:Some premium fiberglass shingles come with extended warranties (e.g., 30 to 50 years), which can affect the overall price. Higher-end shingles with stronger warranties generally cost more.

 - Installation Warranty: Many reputable contractors offer warranties on the workmanship, which can add peace of mind but might also slightly increase the cost.
