The answer to 'how to clean leak repair' is to thoroughly inspect and clean the area around the leak to prepare it for repair. First, use a stiff-bristle brush to remove any loose debris, dirt, or corrosion from the affected area. Then, clean the surface with a degreasing cleaner to ensure the repair material adheres properly. Finally, allow the area to fully dry before applying the appropriate sealant or patching compound to stop the leak.
Proper cleaning and preparation is key to ensuring the leak repair is effective and long-lasting. Be sure to take safety precautions like wearing gloves and eye protection, and consider calling a professional roofer if the leak is extensive or difficult to access.
