On average, roofs typically need cleaning every 3 to 5 years, depending on factors like tree coverage and humidity. Homes in Ottawa, where the heat and humidity in the summertime is oppressive, are often more susceptible to algae, mold, and moss growth, which might require more frequent roof cleanings. Dark streaks or patches on your roof are a clear indication of algae and mold growth, indicating that it’s time for a cleaning.
Tips for Extending the Lifespan of Your Roof
- Avoid High-Pressure Washing: Using high-pressure washing on your shingles can cause significant damage by loosening the granules that protect the shingle’s surface. This type of damage is typically not covered by homeowner’s insurance, making it essential to avoid pressure washing shingles.
- Regular Gutter Cleaning: Keeping your gutters clean is crucial for preventing water damage and ensuring proper drainage away from your roof and foundation. Blocked gutters can lead to water pooling on your roof, which may cause leaks and other damage.
- Trim Overhanging Branches: Make sure to keep tree limbs and large branches trimmed back from your roof. Overhanging limbs can drop debris that leads to moss and algae growth, and strong winds can cause branches to scratch or damage the roof surface.
Choosing the Best Roof Cleaning Method
The most effective and safest way to clean your roof is through a soft washing process. Here’s why:
- Soft Washing Technique: This method uses low pressure combined with specially formulated cleaning solutions to gently remove dirt, algae, and moss without damaging your shingles. Unlike high-pressure washing, soft washing protects the integrity of your roof’s surface.
- Sodium Hypochlorite-Based Solutions: These commercial-grade detergents are designed to effectively kill algae and prevent it from returning. When applied correctly, these solutions provide a deep clean while being gentle on your roof’s materials.
- Professional-Grade Soaps: In addition to sodium hypochlorite, high-quality commercial soaps are used to enhance the cleaning process. These soaps help break down grime and organic material, ensuring a thorough clean.
Why You Should Always Hire a Professional
While roof maintenance is crucial for extending the life of your roof and protecting your home, it’s a task best left to the professionals. Roof cleaning involves specialized equipment and working at heights, which can be risky for someone without the proper training. A professional roof cleaning service has the experience and tools needed to perform the job safely and effectively, reducing the risk of accidents and damage.
