How Does Humidity Affect My Roof in Myrtle Beach?

Humidity affects Myrtle Beach roofs in a few ways: it feeds the black algae streaks you see on many shingles, traps moisture in poorly vented attics, and keeps roof decking damp longer after rain. Over time that moisture can rust nails and rot wood. Good ventilation and algae-resistant shingles help a roof handle the humid climate.

How Does Humidity Cause Algae?

Moisture on the roof surface lets algae grow, leaving black streaks. Read how to stop black algae streaks.

What Does Humidity Do in the Attic?

Warm, wet air can condense on the cool decking, causing damp insulation and rust. See attic ventilation problems.

How Can I Protect My Roof?

• Make sure the attic is properly vented.
• Keep trees trimmed so the roof dries.
• Choose algae-resistant shingles on your next roof.
