Hail can damage roof flashing by denting, cracking, or dislodging the metal pieces designed to seal and protect roof edges and joints. Compromised flashing can lead to gaps where water can seep into the roof, causing leaks and water damage to the interior. Damaged flashing may also allow moisture to infiltrate under shingles, weakening the roof structure over time. Hail impact can distort the shape of the flashing, reducing its effectiveness and requiring prompt repair or replacement. Addressing flashing damage quickly is essential to maintaining the roof's water resistance and preventing more extensive property damage.
