Metal roofs come in numerous colors and textures; some designs even look like traditional wood shakes or clay tile roofing. Once installed, your home’s curb appeal shoots through the roof. Moreover, homeowners love metal roofing for its durability, which has been hanging tough for over 50 years with minimal upkeep. By comparison, asphalt, another popular roofing material, only lasts about 20 years and needs far more maintenance.

But even though metal roofs last long, they don’t last forever. Over time, they can develop holes from corrosion or even the impact of a fallen tree branch. When this happens, you’ll want to know how to repair a hole in a metal roof. Let’s find out in this guide.

What Causes a Metal Roof to Develop Holes?

Are you wondering how to repair a hole in your metal roof? If you learn about its three common causes, you could prevent the problem.

1. Corrosion or Rusting

Exposure to oxygen and moisture from rain or snow causes metal to deteriorate from a chemical reaction called oxidation. Roofs made of iron or iron alloys are particularly susceptible to rusting. This problem can quickly eat away the roof and form holes.

2. Physical Impact

Large hail pellets, lightning strikes, or falling debris can puncture a metal roof. These impacts compromise the roof’s integrity, leading to potential leaks and further structural damage that requires roof repairs.

3. Installation Errors

Improper installation can lead to open seams and loose fasteners that leave gaps and holes in the roof. Some metals react corrosively when mixed. For instance, fastening a copper roof panel with an aluminum bolt will cause corrosion that forms a hole.

How Much Does Metal Roof Repair Cost?

Before considering how to repair a hole in a metal roof, determine the project’s cost. Factor in the size of the hole, the type of metal, and the complexity of the repair. Here’s an overview of your potential costs for professional repairs:

  • Size of the Hole: Minor puncture repairs typically cost a few hundred dollars. More extensive or more complex damage can cost $1,000 or more. Severe roof damage may require a complete roof replacement.
  • Type of Metal: Less expensive metals like steel or aluminum are cheaper to repair. Materials like copper or zinc may incur higher repair costs.

Labor Costs: Repair work typically requires professional metal roofing contractors, and labor costs vary by region. Expect to pay between $50 and $80 per hour for skilled labor.

Step-by-Step Guide for How to Repair a Hole in a Metal Roof

A metal roof allows you to replace just a single panel instead of an entire section if there’s a hole. Before you begin repairs, access the roof to assess the damage. Use a tape measure and snips to accurately measure and cut the new panel to match the old one. It’s also wise to enlist help to complete the task more efficiently and safely.

  • Step 1: Inspect your tools and equipment to ensure they’re safe to use.
  • Step 2: Wear safety gear—goggles, gloves, non-slip boots, and a harness for a high roof.
  • Step 3: Securely set up a ladder on level ground to reach the roof.
  • Step 4: Once on the roof, have your assistant hand you tools as needed, positioning them near the damaged panel.
  • Step 5: Use a cordless drill to remove screws or fasteners, then lift the panel with a pry bar, avoiding damage to adjacent panels.
  • Step 6: Align the pre-cut panel and secure it with screws to maintain uniformity with other panels.
  • Step 7: Apply sealant along the edges where the new panel meets the existing ones for a watertight finish.

Remember that you’ll likely need a professional roofer to repair large holes and extensive roof damage. Professionals have the skills and equipment to complete the job safely and efficiently.
