How to Clean Asphalt Roof Shingles: 1 Minute to a Cleaner Roof: Quick Tips for Asphalt Shingle Maintenance

Cleaning asphalt roof shingles not only enhances your home's curb appeal but also extends the life of your roof by removing harmful buildup like algae, moss, and debris. Begin by setting up a gentle cleaning process: remove loose debris with a soft-bristle brush or a leaf blower, taking care not to damage the shingles. Prepare a cleaning solution by mixing water with mild dish soap or specialized roof cleaner. Avoid high-pressure washing, as it can loosen or damage the granules that protect asphalt shingles. Apply the cleaning solution with a garden sprayer, allow it to sit for 15–20 minutes, then gently rinse off with a low-pressure hose. For persistent algae or moss, use a solution of 1 part bleach to 3 parts water, making sure to protect landscaping below by rinsing thoroughly. Regularly scheduled cleaning keeps your roof looking fresh and prevents moisture retention that leads to premature aging.
