Look for loose, missing, or crooked screws, and check for damaged or cracked washers. Use a screwdriver or a drill to gently tighten any loose screws—but be careful not to overtighten, as this can crush the washer and create more leaks. Replace any worn or damaged screws and washers with new ones that match the original size and coating. For added protection, apply a metal roof sealant specifically designed for these applications over each repaired screw head.From a designer's perspective, it's important to address maintenance issues like leaking screws not just for function but also for curb appeal.
