6. Maintenance
Regular maintenance will help preserve the appearance and structural integrity of your gazebo.
- Cleaning: Clean the frame and roof panels periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the finish or polycarbonate. Rinse thoroughly with clean water.
- Fastener Check: Annually, or after severe weather, inspect all bolts, screws, and anchors. Tighten any loose fasteners to ensure continued stability.
- Snow Removal: While the roof is designed to handle 7 inches of snow, it is recommended to remove excessive snow accumulation to prevent undue stress on the structure, especially during prolonged periods of heavy snowfall.
- Drainage: Ensure the inclined roof's drainage paths remain clear of leaves and debris to maintain waterproof performance.
