Expert Tips: Roof Cleaning Mistakes to Avoid

Roof cleaning is among the many things homeowners should consider to stay on top of home maintenance. Being a prominent component of any house, roofs are exposed to harsh weather conditions, dust, dirt, and other things. Regular roof cleaning extends roof life, makes it easy to identify minor issues before they advance into major problems, and improves its energy efficiency.

Ignoring regular roof cleaning and other maintenance practices significantly affects your roof’s integrity and aesthetic appeal. It can also void your house insurance. You should employ the best roof cleaning techniques to avoid damaging the roof. Hiring roof cleaning professionals is a safe bet, as they can avoid the following common roof cleaning mistakes.

Roof Cleaning Mistakes to Avoid

1. Avoid Pressure Washing

Pressure washing is a powerful and effective way of cleaning several surfaces at home. While it can expertly remove stubborn stains from bricks, stone, blocks, and masonry, pressure washing isn’t recommended for roof cleaning. Pressure washers are powerful and can easily damage your roof.

Pressured water can also pass through small cracks and holes in your roof, causing water damage to the attic and other structural components. Roofing materials are ideally designed to prevent water from entering through the roof. However, they can’t withstand pressurized water directed at a very close range.

2. Wrong Choice of Cleaners

Unfortunately, not all roof cleaning products are suitable for all types of roofs. For instance, the best roof cleaning products for asphalt shingles may not suit other metal roofs or other roofing materials. Some industrial cleaning products available from your local hardware store aren’t suitable for all roofing materials.

Powerful cleaning products can easily wear out and degrade roofing materials. Before using soap, bleach, anti-fungal, and other roof cleaners, check the manufacturers’ recommendations. Manufacturers often list the ingredients and where the products can be used safely. If you’ve hired a roof cleaning company, inquire about their choice of cleaning products before they start cleaning.

3.  Using Very Abrasive Scrubbers

Most people think cleaning a roof is the same as cleaning other exterior surfaces, which is incorrect. You shouldn’t use overly abrasive scrubbers on your roof, even if it is full of stubborn stains, mold, algae, and dirt. Using abrasive scrubbers or sharp objects can damage the roof, leading to expensive repairs. Always consult the roofing material manufacturer for the recommended scrubbing options.

4.  Walking on the Roof Incorrectly

Roof cleaning is primarily reserved for professionals because of safety issues. Some roofing materials aren’t strong enough to support your weight. Most ridge gaps on the roof are designed to crack when there’s a heavy load to preserve other parts of the roof. Walking on a steep roof is also dangerous, especially when wet. Falling from this height can cause serious injuries. Hiring roof cleaning professionals can save you from the cost of roof repair and the risk of sustaining injuries.

5. Overlooking Safety Precautions

Roof cleaning can be hazardous, especially if you’re not experienced with working at heights. Always prioritize safety by using proper safety equipment, such as harnesses and sturdy ladders. If you’re uncomfortable with heights or unsure about the cleaning process, consider hiring professional roof cleaners.

6. Neglecting Regular Inspections

Proper roof maintenance starts with regular inspections. Many homeowners make the mistake of neglecting this essential step, leading to the accumulation of debris, leaves, and algae on the roof’s surface. Schedule bi-annual inspections to identify potential issues before they escalate into more significant problems.

7. Using High-Pressure Washing

While it may be tempting to blast away dirt and grime with high-pressure washing, this method can be detrimental to your roof. High-pressure water can damage shingles, strip away protective coatings, and cause water infiltration. Instead, opt for low-pressure washing or soft washing techniques to clean your roof safely.

8. Neglecting Gutter Cleaning

Roof cleaning should also include gutter maintenance. Clogged gutters can lead to water backups, which may damage your roof and the interior of your home. Ensure that your gutters are clear of debris and functioning correctly.

9. Scrubbing Shingles Vigorously

When cleaning your roof, avoid scrubbing shingles too vigorously. Gentle cleaning is sufficient to remove debris and stains without causing damage. Vigorous scrubbing can lead to shingle granule loss, reducing its lifespan and effectiveness.

10. Ignoring Moss and Algae Growth

Moss and algae not only mar the appearance of your roof but also trap moisture, leading to premature deterioration of roofing materials. Address moss and algae growth promptly using appropriate cleaning methods.

11. Failing to Trim Overhanging Branches

Overhanging branches can deposit leaves, twigs, and sap onto your roof, creating an ideal environment for mold and mildew growth. Trim back trees near your roof to prevent debris buildup and potential damage.

12. Using Improper Tools

Avoid using sharp tools or equipment that can damage your roof’s surface while cleaning. Stick to soft-bristled brushes, non-abrasive sponges, and gentle cleaning tools to maintain your roof’s integrity.

13. DIY Repair Attempts

If you discover issues while cleaning your roof, refrain from attempting DIY repairs unless you’re experienced in roofing work. DIY repairs can worsen the problem and may void any existing warranties on your roof, it is better to call experienced roofing professionals.

14. Not Checking for Leaks

During roof cleaning, take the opportunity to inspect for leaks or signs of water damage inside your home. Catching leaks early can prevent extensive damage to your property.

15. Cleaning in Extreme Weather

Avoid cleaning your roof during extreme weather conditions, such as high winds, heavy rain, or freezing temperatures. Cleaning under such circumstances can be dangerous and may lead to ineffective results.

16. Skipping Professional Cleaning

While some homeowners may prefer DIY approaches, professional roof cleaning services offer expertise and experience that can ensure a thorough and safe cleaning process.

17. Not Protecting Surrounding Landscaping

Before starting the cleaning process, take precautions to protect your plants, shrubs, and landscaping from cleaning chemicals and debris.

18. Failing to Secure Loose Shingles

If you notice any loose or damaged shingles during cleaning, take the time to secure or replace them promptly to avoid potential leaks.

19. Not Rinsing Thoroughly

After cleaning, ensure you rinse your roof thoroughly to remove any cleaning residue, preventing damage and promoting a clean appearance.

20. Avoiding Steep Roofs

Cleaning steep roofs can be challenging and dangerous. If you have a steep roof, consider hiring professionals with expertise in handling such tasks.

21. Allowing Moss to Accumulate

If moss begins to grow on your roof, address the issue promptly. Moss can lead to water retention and cause long-term damage.

22. Neglecting Attic Ventilation

Proper attic ventilation is essential for a healthy roof. Ensure your attic is well-ventilated to prevent heat and moisture buildup, which can damage your roof’s structure.

23. Using Incorrect Cleaning Techniques

Different roofing materials require specific cleaning techniques. Research and use the appropriate cleaning method for your roof type.

24. Overlooking Rust and Corrosion

If your roof has metal components, keep an eye out for rust and corrosion. Address these issues promptly to prevent further deterioration.

25. Neglecting Professional Inspections

Even if you’re diligent with DIY maintenance, professional inspections are crucial to catch hidden issues and extend the life of your roof.
