Gutter repair in Hilton Head Island tends to fall into two camps: sudden damage from storms and falling limbs, and slow damage from salt air working on fasteners and seams. A&A Island Services repairs gutters of any make or model, and the owner comes out to every repair.
Why Gutters Fail on Hilton Head Island
Storms do the fast damage. During Hurricane Matthew on October 8, 2016, the National Weather Service recorded an 87 mph gust at Hilton Head and judged from tree and home damage that winds reached at least 100 mph on Beaufort County's sea islands. The Island News reported that the island lost about 100,000 trees and that the Town removed 2.5 million cubic yards of debris in all. On a smaller scale, one pine limb in a summer squall can crush the front lip, rip hangers out of the fascia and kink the downspout.
Salt does the slow damage. FEMA's Technical Bulletin 8 cites North Carolina tests in which iron corroded 10 times faster 80 feet from the shoreline than 800 feet back, and it notes that the ocean-facing side of a building corrodes faster. Sheltered spots, such as the back of a gutter tight against the fascia, can be worse because rain never rinses the salt away. On beach homes in Forest Beach, along Palmetto Dunes' 11 miles of saltwater lagoons and near Broad Creek at Spanish Wells, it shows up first at screw heads, hanger straps and seams.
Age adds the rest. About 6 in 10 island housing units predate 1990, per Census Bureau estimates, and older sectional systems often leak at the joints, sag where hangers were spaced wide, and rust through at end caps and outlets. FEMA also warns that dissimilar metals, such as stainless steel and aluminum, corrode faster in contact with salt water, so a mismatched screw from a past repair can become the next leak.
