Factors That Affect the Cost of Garage Roof Installation
Like any roofing system, a garage roof also needs your frequent attention. So before you decide to install or replace your garage roofing system, it is essential to consider certain factors.
Size of the Roof
Whether it is a home roofing project or a garage roof installation, the size of the roof is a significant factor in determining the cost of the project. A larger roof will require more materials and more labor, resulting in a higher cost. For example, a smaller garage with space for only one car (usually garages with an area of 280-320 square feet) will be less expensive than a garage with space for two or three cars (400-700 square feet).
Type of Material
The type of material used for the garage roof is also an essential factor that affects the cost. The price of different roofing materials varies significantly, with some materials being more expensive than others. For example, metal roofing is generally more expensive than asphalt shingles.
Here are some roofing materials you can consider for your garage roof:
Asphalt Shingles
Asphalt shingles are one of the most common roofing materials available, and 70% of homes across the country have an asphalt roofing system. If you already have a shingle roof on your home, why not use the same material for your garage?

Metal Roofs
Metal is another popular choice for garage roofs due to its longevity and low maintenance. Metal roofs are available in several materials, including aluminum, copper, and steel. You can expect them to last on your garage for more than 50 years with ease.
However, as a drawback, they can be quite expensive. Metal roofing typically costs $5 to $12 per square foot. They are also challenging to install, so if you do not know how to install a metal roof on a garage, contact a professional roofing company.
Tile Roofs
This is another option for garage roof installation. Tile roofs are available in several materials, including clay and concrete. Tile roofs are heavier than other roofing materials, so it’s important to ensure that the garage’s structure can support the weight of the tiles.
| Roofing Material | Cost per Sq Ft | Key Characteristics |
|---|---|---|
| Asphalt Shingles | $3–$7 | Most affordable, widely available |
| Metal Roofs | $5–$12 | Durable, long-lasting, higher upfront cost |
When selecting a roofing material for your garage, it’s important to consider not just the upfront cost, but also the long-term maintenance and replacement costs. You can contact our roofing professionals to get a better idea of your total investment.
Labor Cost
Local labor costs are a significant factor in determining the cost of a garage roof installation. Labor typically represents 40-60% of the total project cost. The cost of labor can vary depending on the location of the installation, as labor costs are generally higher in metropolitan areas where the cost of living is higher. It’s important to work with a contractor who is familiar with local labor costs and can provide an estimate that takes these costs into account.
Cutting corners on labor costs by hiring inexperienced or unlicensed workers can result in significant safety issues and costly repairs in the future. So if you want to get a durable roof that’s installed correctly, hire qualified laborers to do the job.
Removal of the Existing Roof
The removal of an existing roof is another factor that can affect the cost of a garage roof installation. If an existing roof needs to be removed before the installation of the new roof, it will add to the overall cost of the project.
The cost of removing an existing roof can vary depending on the type of material already on the roof, and the size of the roof. For example, removing a metal roof will be more expensive than removing asphalt shingles.
Additional Costs: Gutters
When replacing your garage roof, you may also need to consider updating your gutters. Exterior renovations often require simultaneous updates to ensure everything works together properly. Gutter replacement typically averages $1,100 to $1,200, which should be factored into your total project budget.

What are the signs that my garage roof needs replacement rather than just repair?
Look for multiple missing or curling shingles, water stains on interior garage walls or ceiling, sagging roof deck, or visible daylight through the roof boards. If your garage roof is over 20 years old and showing these signs, replacement is typically more cost-effective than repeated repairs.
Can I use a different roofing material on my garage than what’s on my house?
Yes, you can use different materials, though matching your home’s roof creates better aesthetic cohesion and property value. Many homeowners choose more economical materials for detached garages while prioritizing durability. Consider factors like weight compatibility with your garage structure and local building codes when selecting alternative materials.
How long does a typical garage roof installation take to complete?
Most single-car garage roof installations take one to two days, while two-car garages typically require two to three days. Timeline depends on weather conditions, complexity of the roof design, whether tear-off is needed, and crew size. Delays can occur if structural repairs are discovered during installation.
Do I need a permit for garage roof replacement, and who handles that?
Most municipalities require building permits for garage roof replacement to ensure work meets safety codes and structural standards. Reputable roofing contractors typically handle permit applications and inspections as part of their service. Check with your local building department about specific requirements in your area.
What maintenance does a garage roof need after installation to maximize its lifespan?
Inspect your garage roof twice yearly for damaged shingles, clean gutters regularly to prevent water backup, trim overhanging tree branches, and remove debris accumulation. Address minor issues immediately to prevent larger problems. Annual professional inspections can catch potential issues early and extend your roof’s service life significantly.
