Additional Cost Factors
Your roofing contractor may need to tack on costs for preparing to install your garage's replacement roof. Here's a look at the common costs to keep in mind when planning your budget for this project.
Demolition and Prep
As you factor a new roof into your overall garage remodel cost, remember that your roofing contractor will need to remove your existing roof before installing a replacement. On average, contractors charge between $1 and $5 per square based on the complexity of your roof and the weight of the roofing material being pulled away. The cost to haul away old roofing materials is around $400. However, some contractors work the cost of disposing of your old roof into the rate per square foot.
If a new roof ridge vent needs to be installed for ventilation in preparation for your new roof, expect a roof pro to charge between $300 and $650. Depending on the style of your roof, you may require box vents costing an average of $500 each, soffit vents costing between $315 and $465 each, or gable roof vents costing between $60 and $150 each.
If your roofing contractor recommends replacing existing chimney flashing before putting on your new roof, expect the cost to range between $400 and $1,600. This upgrade will ensure that water damage doesn't threaten your home's framing.
Your contractor is also likely to install a new drip edge with your new roof. A drip edge is a type of metal flashing that keeps water out of your roof by directing it to the gutters. It is placed on the edge of the roof. With an average cost of $1 to $3 per linear foot for a new drip edge, the cost to fully protect an average garage roof is around $375. While costs for drip edges can go as high as $1,000, you're more likely to see the price as low as $150 to $200 with a new garage roof installation because contractors will blend the cost into the total project cost.
Permits
Code and permit requirements vary from place to place when it comes to replacing an existing garage roof. In general, removing and replacing shingles or tiles would be considered a structural change that requires a permit. If you hire a roofing pro, they will take care of pulling all permits required for the project. On average, the cost for a permit for replacing a garage roof is between $100 and $400.
Roofing Material
The type of material you select for your roof redo dramatically impacts overall project costs. Here's what you can expect to pay for common roofing options:
Asphalt shingles: $3–$7 per square foot
Metal: $7–$13 per square foot
Standing seam metal: $4–$30 per square foot
Wood shakes: $6–$13 per square foot
Clay tiles: $10–$20 per square foot
Slate/stone: $15–$30 per square foot
Composite: $4–$8 per square foot
DIY Garage Roof Replacement vs. Hiring a Pro
If you'd like to try replacing your own garage roof, you may be able to bring down the cost for a 350-square-foot roof from $2,625 to as low as $1,575 by cutting out labor. Our How to Replace a Roof From Start to Finish guide lays out the scope of this type of DIY project. However, homeowners should keep in mind that professional roofers provide expertise when installing underlayment and flashing to protect your home against water damage. Additionally, roofers are able to get projects done in a matter of hours using multiple workers.
DIY garage roofing has a risk for low-quality work that could leave your garage exposed to rot and mold. Getting a quote for a new roof from a local garage remodeling company near you can help you compare DIY vs. professional costs. In some cases, a full-service garage company may be the answer if you're wondering who to hire to install a garage door along with a new roof.
Garage Roof Replacement vs. Repair
With average roof repairs costs between $700 and $2,000 for a 350-square-foot structure, paying for extensive repairs instead of replacing a worn-out roof may not be the best idea. If repairing an existing garage roof exceeds 50% of the cost of installing a new roof, it's better to go with the peace of mind of a full upgrade. Additionally, a roof that is near the end of its warranty or expected lifespan should also be replaced instead of sinking money into repairs. On average, roof lifespan ranges from 20 to 30 years for asphalt and wood shingles to 50 to 100 years for metal and tiles.
Garage roof repairs are generally best when a roof has surface-level problems. The cost to replace a few missing shingles or take care of a minor leak may range from $100 to $300. However, sagging or damaged fascia could total $2,500 to $3,000 for a garage roof.
How You Can Save Money While Replacing a Garage Roof
Bring down the cost to replace a garage roof using these tips:
If you feel confident about climbing on your home's roof, removing your existing roof could save you up to $700 on your roof installation project. The cost to rent a dumpster for a week to dispose of your old roofing materials ranges from $293 to $479.
Keeping the same roofing material as your current roof could also reduce costs by allowing you to keep existing vents and gutters.
Choose a flat roof. In general, garage flat roof replacement cost is lower compared to sloped roofs because the simple design and reduced surface area make flat roofs easier to install.
Get at least three quotes from local roofing contractors to compare costs.
Does Replacing a Garage Roof Increase Home Value?
When updating a home, the return on investment (ROI) on new roofing is between 48% and 61%. ROI is best when the roof has been installed professionally with a warranty that can be passed on to the new homeowner. A new garage roof adds value by increasing a home's efficiency and reducing risks of water damage. If you're replacing a worn, damaged garage roof, the aesthetic appeal can boost curb appeal.

Frequently Asked Questions
If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.
If you're looking for a dependable and affordable option for garage roofing, asphalt shingles offer a durable way to blend a detached garage in with the surrounding residential aesthetic. If you're looking for a more durable and protective option because you're storing expensive equipment in your garage, consider metal roofs that perform well against snow, ice, hail, and heavy rains.
