CLEANING ASPHALT SHINGLE ROOFS: A COMPLETE GUIDE

Regular cleaning of asphalt shingle roofs is essential to maintain their appearance and extend their lifespan, especially in Montreal’s weather conditions. Debris, moss and algae can accumulate on the shingles, causing damage and reducing their effectiveness. To clean effectively, start by removing debris such as leaves and branches using a soft broom or leaf blower. Avoid using abrasive tools that could damage the shingles. To remove moss and algae, use a cleaning solution of two parts water to one part bleach, applied with a low-pressure sprayer. Let the solution sit for about 15 to 20 minutes, then rinse thoroughly with clean water. It is crucial to work on cool, cloudy days to prevent the solution from drying too quickly. To prevent moss and algae from reappearing, consider installing zinc or copper strips along the roof ridge, as these metals inhibit the growth of pests. Finally, performing regular roof inspections can help spot and treat any signs of deterioration quickly.
