PORTLAND, Ore.—Labor Day is a good time for homeowners to roll up their sleeves and get to work to prepare for the upcoming fall and winter season.


That means starting at the top by getting a home’s roof in shape. While metal roofs are well-known for being easy to maintain, exceptionally long lasting and durable, the Metal Roofing Alliance (MRA) recommends homeowners care for and clean their metal roofs regularly to ensure maximum performance.


“Simple steps to take care of your metal roof will help it stay beautiful, fresh and protect its very long life,” said Renee Ramey, executive director of the MRA. “Fortunately, quality metal roofs also are one of the easiest types to clean and care for, and Labor Day is an ideal time to consider preparing your roof for the coming season”


Cleaning a metal roof regularly helps reduce damaging elements such as pollution, airborne dirt, organic material debris, pollen and mildew. Left unaddressed, these elements can lead to issues such as chalking over time. Thanks to special coatings and paint, cleaning a metal roof is not only easy, but more environmentally friendly, eliminating the need for harsh chemicals. In fact, plain water can often effectively wash away dirt, dust and other debris from a metal roof.


While it’s always good to check with the specific metal roofing manufacturer, below is a simple home cleaning remedy useful for most metal roofs, based on guidance from leading MRA members:


  1. If water alone isn’t enough to remove common dirt and debris, mix 1/4 cup detergent (including mild laundry detergents, car washing soap, mild dish soap) per gallon of water.

  2. Apply the solution to roof surface using washcloth, sponge, a soft bristle brush and/or non-abrasive pad. The goal is to use the lightest touch that will effectively do the job.

  3. Let stand for 5 to 10 minutes.

  4. Thoroughly rinse surface with plain water.


For more stubborn substances such as grease, tar or mildew, always follow the recommendations of the metal roof manufacturer. To ensure a roof stays cleaner and in peak performance, be sure to pay attention to cleaning and fixing any gutter issues, trimming vegetation away from the roof and having a professional inspect your roof periodically.


Other tips for caring for a metal roof:


1) Make it a habit. Labor Day is a good time to get roofs ready for colder, wetter weather and performing roof maintenance such as cleaning out gutters, ensuring snow guards are in place and more.


2) Follow directions. Don’t overuse or abuse cleaning agents on your metal roof. Follow the manufacturer’s instructions to help protect and maintain roof warranties.


2) Say never. Never use steel wool, wire brushes, sandpaper, high pressure power washers, souring powders, paint removers or thinners on a metal roof.


3) Test carefully. If you’re unsure about a cleaning product, test it first by trying it on a small, less noticeable area before you use it on an entire roof.


4) Above all, be careful. There are many safety precautions to consider when getting up on any type of roof, no matter what the material. The best advice is to don’t do it if you are not comfortable or prepared to take the proper precautions. Hiring a professional, reputable roof cleaning service that is experienced and knowledgeable is the very best way to ensure safety and a job well done.
