Do Metal Roofs Need to be Cleaned?

The simple answer is yes. Although you don’t have to clean your metal roof on a daily basis, occasional cleaning is essential to preserve your roof’s integrity and original appearance.

Major metal roof issues like roof leaks can create a mess inside your home or commercial property. With timely repair, you can prevent bigger future problems that could cost you more than you anticipated.

Step-by-Step Guide to Clean Your Metal Roof without Scrubbing

Before starting your clean-up, a gentle wash is recommended to eliminate loose particulate matter, allowing the cleaning agents to work their magic effectively. You can also identify any hidden damage with a pre-clean-up and repair it later.

To ensure your safety during metal roof cleaning, wear non-slip shoes to avoid falling. Let’s start with the process:

Step 1: Prep the Surroundings for Safe Cleaning

Before initiating the cleaning process, protect plants, lawns, and other nearby surfaces from potential runoff. Cover the specific areas using plastic sheeting or tarps and redirect the downspouts to manage the flow.

Step 2: Prepare the Right Cleaner for Metal Surfaces

Following the manufacturer’s guidelines, mix a gentle, eco-friendly cleaning agent with water. Remember to choose a cleaner specifically designed to effectively eliminate dirt and debris from metal roofs without scrubbing.

Step 3: Pre-Wash the Roof

Now, gently rinse the entire metal roof using a low-pressure garden hose to remove loose dirt and dust. For cleaning a stone-coated metal roof, keep the hose pressure below 500 PSI. This initial rinsing is important as it will allow the cleaning solution to completely penetrate and lift stubborn filth.

Step 4: Apply the Cleaning Solution Evenly

Use a specifically designed sprayer or a soft-bristle brush attached to a long handle to apply the cleaning solution. Ensure even distribution across the entire metal roof surface, allowing the solution to sit and break down the accumulated dirt and grime.

Step 5: Allow Time for Deep Cleaning Action

Allow the cleaning solution to settle on the roof for the time specified by the product instructions. Avoid letting the solution dry completely to prevent streaking or residue.

Step 6: Wash Off Residue and Lifted Dirt

Rinse the roof again with the garden hose, starting from the top and working downwards in sections. Ensure that all the cleaning solutions and loosened dirt are completely washed away.

Step 7: Spot Clean Stubborn Areas

Inspect the roof for any remaining spots. If necessary, apply the cleaning solution to specific areas and use a soft cloth or sponge to gently dab away the dirt.

Step 8: Schedule Periodic Cleanings for Longevity

To keep your metal roof in top condition, schedule regular cleanings, especially after the rainy season, to prevent buildup and maintain the integrity of the roof.

Note: If you’re wondering how to clean your metal roof before painting, the process is the same. You just need to let the roof dry for a few hours or overnight after cleaning.

Thinking of Cleaning Your Metal Roof? Read This First

You might be thinking about cleaning your metal roof using DIY methods. While there is no doubt that these methods work, there is a high chance that you might make mistakes, potentially turning your cleaning sessions into a headache.

So, we need to warn you about some fatal mistakes that might jeopardize your metal roof wash-up.

• Using Corrosive Cleaners on Metal Roofs

Don’t make a mistake by believing that stronger chemicals result in a cleaner roof. In reality, harsh chemicals can corrode metal and strip away protective coatings. You can prevent such a disaster by always opting for cleaners, specifically formulated for metal roofing.

• Skipping Protection for Nearby Plants and Lawns

As we mentioned earlier in the process section, it is important to protect your property and vegetation around the house before starting the clean-up. Otherwise, the chemical runoff would significantly damage these surrounding elements. So use tarps to cover these elements and redirect downspouts for preventing damage, as instructed before.

• Blasting Your Roof with High-Pressure Washing

The allure of high-pressure washing to blast away dirt can be tempting, but this forceful method can damage your metal roof. Stick to a gentle, low-pressure garden hose as advised in Step 3: Rinse the Roof to avoid dents and preserve the integrity of your roof.

• Skipping Corners or Edges

An inconsistent application of cleaning solution can lead to streaking and areas that don’t get as clean. Use a soft-bristle brush or sprayer to ensure even distribution, as mentioned in Step 4: Apply the Cleaning Solution.

• Leaving the Solution to Bake in the Sun

Allowing the cleaning solution to dry on your metal roof can create hard-to-remove streaks and residues. Keep an eye on the solution’s dwell time, and ensure it doesn’t dry by following the guidelines from Step 5: Let the Solution Work.

• Rinsing Too Quickly or Incompletely

An incomplete rinse can leave behind soap residues that attract more dirt. Ensure a thorough rinse from top to bottom.

• Ignoring Minor Spots and Edges

You might ignore the minor spots and patches, but they can turn into bigger issues over time. Therefore, remember to perform post-cleaning assessments.

• Not Sticking to a Schedule

Not maintaining the cleaning schedule can cause substance build-up that proves harder to clean over time. Therefore, follow your cleaning schedule to avoid intensive labor later.
