Asphalt shingles are a popular choice for roofing due to their durability and aesthetic appeal. However, they require regular cleaning to maintain their effectiveness and extend their lifespan. Proper cleaning not only enhances your roof’s appearance but also prevents damage caused by algae, moss, and debris. Here’s a comprehensive guide to cleaning asphalt shingles safely and effectively.

1. Why Cleaning Asphalt Shingles is Essential
Over time, asphalt shingles accumulate dirt, moss, algae, and debris. These can cause:
- Reduced curb appeal due to unsightly streaks and stains
- Water retention that leads to shingle deterioration
- Shortened roof lifespan and costly repairs
Regular cleaning prevents these issues and keeps your roof functioning optimally.
2. Use the Right Cleaning Method
Pressure washing might seem like an effective option, but it can damage shingles and strip them of their protective granules. The best approach is soft washing, which uses a low-pressure spray combined with cleaning solutions to remove contaminants. Benefits of soft washing include:
- Gentle cleaning that doesn’t harm shingles
- Effective removal of algae, moss, and mold
- Longer-lasting results compared to pressure washing
3. Steps to Clean Asphalt Shingles
To ensure a thorough and safe cleaning, follow these best practices:
- Preparation: Clear debris from the roof and surrounding gutters. Cover plants and outdoor furniture to protect them from cleaning solutions.
- Apply Cleaning Solution: Use a soft washer to apply a biodegradable solution made specifically for roofs. Avoid household cleaners that might harm shingles.
- Let it Sit: Allow the solution to soak for 15–20 minutes to break down dirt and algae.
- Rinse Gently: Use a soft spray nozzle to rinse the roof. Ensure the water flows downward to prevent shingle displacement.
- Inspect: Check for missed areas and repeat the process if necessary.
4. Avoid Common Cleaning Mistakes
Improper cleaning can do more harm than good. Avoid these common pitfalls:
- Using high-pressure washers: These can erode shingles and cause leaks.
- Skipping protective measures: Failing to cover plants or windows may lead to damage from cleaning chemicals.
- Ignoring safety precautions: Always wear slip-resistant footwear and use safety harnesses when working on a roof.
5. Benefits of Professional Cleaning
While DIY cleaning is possible, hiring professionals ensures the job is done safely and effectively. Expert cleaners use specialized equipment and techniques, providing benefits such as:
- Extended roof lifespan
- Prevention of damage to shingles
- Time savings and peace of mind
