How Much Does It Cost to Replace A Garage Roof?

Although it might not be the first thing that comes to mind when thinking about home maintenance, your garage roof is crucial for protecting your possessions from the elements. If damage is left unaddressed, a full roof replacement will be required to preserve structural integrity and protection.

This comprehensive blog post will examine every aspect influencing garage roof replacement costs. We’ll dissect everything you need to know to allocate funds for this home renovation project.

What Is The Average Cost To Replace A Garage Roof?

Any homeowner who needs a garage roof replacement may have to make a sizable investment, and the price will depend on several factors. For a better understanding, consider the following costs related to garage roof replacements:

#1. Roof Material Costs

> Asphalt Shingles

Cost: $2 to $5 per square foot

Asphalt Shingles

The first option is asphalt shingles, which are among the most popular and affordable choices for replacing a garage roof. They are made of an asphalt-coated fiberglass mat and are available in various colors and designs. For a typical single car garage, asphalt shingles usually cost between $1,000 and $1,700.

> Metal Roofing System

Cost: $5 to $15 per square foot

Metal Roofing System

Another common option for garage roofs is a metal roof, which is favored for its longevity and low maintenance needs. Metal roofs come in various materials, including steel, copper, and aluminum, and they generally last over 50 years. However, the average cost for a standard one car garage roof ranges from $1,400 to $3,600.

> Modified Bitumen

Cost: $4 to $7.50 per square foot

Modified Bitumen

Modified bitumen is a flexible, UV-resistant flat roofing option that is more affordable than PVC or metal, making it popular for garage roofs. Its durability, ease of installation, resistance to weathering and cracking, and longevity of up to 20 years with maintenance make it a good choice. However, its typical replacement cost for a one car garage ranges from $1,100 to $2,100 installed, covering materials, labor, underlayment, and flashing.

> EPDM Membrane 

Cost: $4 to $10 per square foot

EPDM Membrane 

One of the least expensive options for a membrane roof is EPDM,  which usually lasts 20 to 25 years. It is preferred for flat roofs because of its durability, adaptability, and ease of installation. Because EPDM is resistant to UV rays, ozone, and extreme temperatures, it is a reliable material for garage roofs. For a one care garage, EPDM normally costs $1,100 to $2,800 for installation, which includes the membrane, adhesives, and any necessary flashing or fasteners.

#2. Labor Costs

When planning for a garage roof replacement, understanding labor costs is essential. Here’s a breakdown of key considerations and average expenses associated with labor in such projects.

  • Complexity of the Repair: Labor costs rise with the complexity of the project.
  • Size of the Garage Roof: Larger roofs demand more labor, leading to higher costs.
  • Geographical Location: Labor rates vary regionally, impacting overall expenses.
  • Contractor’s Experience and Expertise: Highly skilled contractors may charge higher hourly rates.

Average Labor Expenses

Labor rates are typically between $50 and $100 per hour.

#3. Roof Inspection Costs

Having your garage roof inspected by a professional is crucial to determine the extent of damage and the need for repairs before you start the replacement. A garage’s size and the complexity of the inspection determine how much it will cost, which can range from $100 to $500. Complicated features or accessibility issues can also affect costs. 

Larger roofs may result in higher fees due to longer inspection times. A professional inspection can help identify problems and save time and money by preventing expensive repairs down the road. 

#4. Permit Fees

For most roof replacements or major repairs, a permit is required. Homeowners typically need approval from local authorities before altering their roof’s structure, such as replacing shingles or tiles. While minor repairs may not need a permit, major work usually does to comply with building codes and regulations. 

Permit fees can vary widely, ranging from $50 to $500 or more, depending on the scope of the project and your location. Hiring a licensed roofing contractor is advisable as they can assist with the permit process and ensure compliance.

#5. Roof Clean Up and Disposal Costs

Understanding these factors can help homeowners plan and budget for a successful and cost-effective project:

> Dumpster Rental Costs

Renting a dumpster for roofing debris disposal is common, with prices ranging from $300 to $800. 

> Disposal Fees

Disposal fees at landfills typically range from $40 to $60 per ton. However, this doesn’t cover truck rental, gas, and time spent hauling materials.

> Labor Costs for Cleanup

Labor costs for cleanup vary based on project size and complexity, averaging $2 to $3 per square foot or more.

> Total Cost

Overall, roof cleanup and disposal costs can range from $100 to $500 or more, contingent on garage size and waste volume.

How Much Does A Garage Roof Replacement Cost Overall?

The overall cost of installing a garage roof can range from $1,500 to $6,000 or more, depending on factors like the size of the garage, the materials used, and the complexity of the job. For instance:

  • Small Garage (1-car): $1,000 – $4,000
  • Medium Garage (2-car): $1,200 – $5,000
  • Large Garage (3-car+): $2,500 – $11,000

These estimates include materials, labor, and disposal of old roofing materials but may vary based on location and specific project requirements.

Additional Factors That Affect the Roof Replacement Cost

1. Garage Roof Size:

Larger roofs mean more materials and labor, leading to increased costs.

2. Roof Pitch and Complexity:

Steep or intricate designs require more time and effort, resulting in higher expenses.

3. Existing Roof Deck Condition:

Damage to the roof deck adds to overall project expenses.

4. Location and Cost of Living:

Regions with higher living costs typically have pricier roofing services.

Tips for Saving on Your Garage Roof Replacement

1. Make Informed Material Choices:

Balancing cost and quality is crucial when selecting materials. Investing in durable options initially can save on future garage roof repairs and replacements.

2. Seek Multiple Quotes:

Gather quotes from various contractors to compare costs, scope of work, and contractor reputation.

3. DIY vs. Professional Installation:

If you are experienced, consider DIY installation for cost savings, but be aware of the risks. Hiring a professional will always ensure a safer and proper installation.

4. Prioritize Maintenance:

Regular upkeep extends the lifespan of your garage roof. Keep gutters clear, inspect after severe weather, and promptly address any issues.
