What Is The Best Way To Seal A Leaking Gutter Seam?

The best way to seal a leaking gutter seam is to clean and dry the joint, then apply a continuous bead of gutter sealant inside the seam and re-secure the connector. If the metal is cracked or corroded, replacing that section is more dependable than sealant alone. Mast Roofing repairs leaks, replaces damaged aluminum or copper runs, and installs gutter guards to reduce clogs. In Reading and nearby communities, we document findings with photos and give no-pressure recommendations after inspection.

• Clear debris and rinse
• Dry the seam fully
• Reseal the joint continuously
• Tighten or replace fasteners
• Water-test the repair
