Signs That Your Garage Roof Needs A Replacement

Being aware of your home’s condition is very important. Here are a few signs that indicate your existing garage roof needs replacement:


Roof Leaks

If you notice wet spots on the walls and ceilings, you may need to consider a garage roof replacement. Water dripping inside your garage when it rains is a clear sign that your roof is failing. Ignoring a garage roof leak can lead to bigger problems, like mold or damage to items stored.


A roof that is sagging or dipping not only affects the appearance of your garage but is also dangerous. This often means the roof structure is weak and could collapse. It’s a major sign that you need to install a new garage roof to protect your car and other belongings from sudden roof failure.

Missing or Damaged Shingles

Look at your garage from the ground. If you see bare spots, there’s a chance that shingles are cracked, curled, or missing, too. If so, then it is time to think about a new roof. Damaged shingles let water seep in, which can rot the wood underneath and cause leaks. Assess your garage roof and home roof carefully after a storm passes for missing shingles. 


Most garage roofs last about 20-30 years. If your roof is older than this, it might be time for a replacement, even if you don’t see obvious damage. Older garage roofs are more likely to fail suddenly, so replacing them before problems start is wise. Routine inspections allow you spot early signs of wear. 

Daylight through the Roof Boards

Go into your garage on a sunny day and look up. If you can see sunlight through the roof boards, your roof has holes. This means it’s not protecting your garage from rain or snow, and a garage roof replacement is needed soon.

Granules in the Gutters

Check your gutters for small, gritty pieces from the roof shingles. Finding a lot of these granules means your shingles are wearing out. Newer roofs don’t lose granules easily, so this is a sign your roof is getting old.

If you see any of these signs, consult an experienced and reputable roofing partner who can thoroughly assess the condition of your existing roof to make a more accurate decision. 

How Much Does It Cost To Replace A Garage Roof?

The average cost for roofing per square foot for your garage roof can be anywhere between $4-$40. Various materials can be used on a garage roof, affecting the exact cost. For example:

  • Asphalt Shingle Roof: $2-$5 per square foot
  • Metal Roof: $5-$15 per square foot
  • EPDM Roof: $4-$10 per square foot

While budgeting for a garage roof, you need to consider certain things. The quality of the materials you choose will affect the overall garage roof replacement cost. Depending on the area, installation charges and labor costs will differ. On average, labor costs for a garage roof replacement can range between $50 and $100 per hour.

What Is The Minimum Pitch For A Garage Roof?

Garage roofs usually have shallow pitches. Most are built with a 3:12 or 4:12 pitch, meaning they rise 3 or 4 inches for every 12 inches of length.

The minimum pitch needed depends on the roofing material:

  • Asphalt Shingles: 2:12 pitch
  • Metal Panels: 1:12 pitch
  • EPDM: 1/4:12

A steeper pitch helps water and snow slide off faster, making your roof last longer. Always check local building codes for exact requirements in your area.

Pitched Or Flat: Which Garage Roof Is Better?

When choosing between a pitched or flat garage roof, both have their pros. Flat roofs can work well for garages because they’re easy to take care of and often cost less. But if you live where it rains or snows a lot, a pitched roof might be better. 

Your choice also depends on how your house looks. Try to pick a roof that matches your home’s style. This makes everything look cohesive and balanced.

Flat roofs are good for:

  • Easy care
  • Lower cost
  • Modern look

Pitched roofs are good for:

  • Areas with lots of rain or snow
  • Traditional house styles
  • More storage space inside

Think about the local weather, your home’s look, and what you need from your garage. This will help you choose the best roof type.

Is Replacing Your Garage Roof A DIY Project?

Replacing a roof is not a DIY project and should be left to professionals. Roof work requires specialized skills and safety know-how that homeowners typically don’t have.

Even a garage roof can be tricky. DIY attempts might result in big mistakes, like improper installation leading to leaks or potential falls causing injury. Incorrect material use or poor installation can make your roof wear out faster or fail to protect your garage.

In the end, you might spend more money fixing your mistakes than if you had hired a professional from the start.
