How to Clean a Metal Roof in 9 Steps
While metal roofing is a bit of investment, it offers many amazing benefits—they’re energy efficient, durable, long-lasting, etc. However, there is one thing homeowners often neglect to do that can significantly impact a metal roof’s longevity and durability, and that’s properly cleaning the metal roof.
Let’s dive into how to clean a metal roof and why proper maintenance is so important.
Why You Should Clean Your Metal Roof
Keeping up with metal roof maintenance helps you get the most out of your investment by:
Maintaining Curb Appeal
No one likes the look of a dirty, unkempt roof, especially if you’ve paid a lot of money for a metal roof to be installed. Cleaning dirt and debris from the roof’s surface will help prevent mold growth and other discolorations that can decrease home value and turn off prospective buyers.
Removing Trapped Debris
Tree branches, leaves, dirt and other debris can pile up on your roof and cause various problems including rust, mold, scratches, dents and leaks. Built up debris can also draw unwanted pests to your roof where they may find points of entry, leading to potential pest infestations.
Extending the Roof’s Lifespan
One of the core steps of proper metal roof maintenance, keeping your roof clean extends its lifespan by protecting the integrity of key roofing elements like your roofing panels, the surface of your roof, the paint, etc. While metal roofs are built to last longer than traditional asphalt shingle roofs, they can only do so much if they’re constantly carrying the weight of dirt, debris and branches.
How Do You Clean a Metal Roof?
Many homeowners don’t complete this important task simply because they don’t know how to clean a metal roof. Cleaning your metal roof helps keep it looking and functioning well for longer, though it’s important to attempt to clean your metal roof properly and safely to avoid causing unwanted damage or injury.
Steps to Clean a Metal Roof
- Never attempt roof maintenance alone; always have someone spot you in case of emergency.
- Wear shoes with good traction and make sure the bottoms are clear of any rocks or trapped debris to protect your roof from scratches.
- Consider using additional safety equipment such as harnesses to protect you from a potential fall.
- Use an OSHA-approved safety ladder.
- Read the directions carefully for any cleaning product you intend to use on your roof. Some products are toxic and can harm you, the roof, your home’s siding, surrounding plants and wildlife, etc.
Once you have all safety measures in place, follow these easy steps to clean your metal roof:
- From the ground, use a broom or leaf blower to remove leaves, branches and other loose debris. For tough-to-reach spots, you may need to climb up onto the roof for better access.
- Rinse away dirt and dust with water (a garden hose should do the trick.)
- Wash stubborn stains with a mix of dish soap and water using a sponge or soft-bristle brush.
- Always consult a professional before using any harsh chemicals on your roof.
If you’re not comfortable or experienced with DIY roof maintenance, you can always call a roofing expert to tackle the job for you.
Signs of Metal Roof Damage
Mold, Rust, or Corrosion
Anything growing on the surface of your metal roof is a bad sign. Not only is mold, rust or corrosion unsightly, but it could potentially cause serious damage to your home.
Loose Panels of Flashing
Most elements of your metal roof are built to withstand different weather events, though improper installation or severe storms could result in loose flashings or panels—a clear sign that your roof needs attention.
Deep gashes, scratches and dents in your metal roof not only create environments for water to get trapped and cause rust and other corrosion, but weaken the integrity of your roof, shortening its lifespan by years.
