How to Repair a Leak in a Metal Roof: DIY vs. Professional Solutions

Bucket catching water leaking from the roof

Metal roofs are popular for their durability, longevity, and energy efficiency. However, like any roofing system, they can develop leaks over time. If you notice a leak in your metal roof, it's important to address it promptly to prevent further damage. Here's a guide to help you determine whether a DIY repair is feasible or if it's best to seek professional assistance.

Identifying the Cause of the Leak

Before attempting any repairs, it's crucial to identify the source of the leak. Common causes include:

Holes or Punctures:

These can occur from hail, tree branches, or improper installation.


Metal roofs can corrode over time, especially in areas with high moisture levels.

Loose Screws or Fasteners:

Wind or vibration can cause screws or fasteners to loosen, allowing water to seep in.

Damaged Sealants:

Sealants around seams or penetrations can deteriorate over time, creating a pathway for water infiltration.

DIY Leak Repair Options

If you have experience working on roofs and the leak is minor, you can repair it yourself. Here are some DIY options:

Patch Kit:

For small holes or punctures, you can use a metal roof patch kit that includes a self-adhesive membrane and screws.


Apply a waterproof sealant around seams, penetrations, or loose screws to prevent water from entering.

Tighten Screws:

Inspect screws or fasteners and tighten any that have become loose.

Advantages of DIY:


DIY repairs are significantly cheaper than hiring a professional.


You can make the repairs at your own pace and schedule.

Learning experience:

DIY roofing projects can provide a sense of accomplishment and teach you valuable skills.

Disadvantages of DIY:

Risk of Further Damage:

If the repair is not done correctly, it can worsen the leak or cause other problems.


DIY repairs can be time-consuming, especially if you have limited experience.

Safety Concerns:

Working on a roof can be dangerous, and taking necessary precautions is important.

Professional Roof Repair

For larger leaks or concerns about your ability to make the repairs safely, it's best to hire a professional roofer. Advantages of hiring a professional include:

Expertise and Experience:

Professional roofers have the training and experience to identify and fix leaks effectively.

Access to Specialized Tools:

Roofers have access to specialized tools and equipment that can make the repair process easier and safer.


Many professional roofers offer warranties on their work, giving you peace of mind.

Disadvantages of Hiring a Professional:


Hiring a professional roofer is more expensive than DIY repairs.

Scheduling Conflicts:

Scheduling can sometimes be an issue, especially during peak season.

Less Personal Control:

You may have less control over the repair process and materials used.

When to Seek Professional Help

It's generally best to seek professional assistance if:

  • The leak is located in a high or inaccessible area.

  • The cause of the leak is not easily identifiable.

  • The leak is large or is causing significant damage.

  • You do not have experience working on roofs.
