Thomas Roofing | Roofing Services in Saint Helena Island, SC 29920

On the island, high humidity, salt air, and temperature fluctuations can degrade sealants and fasteners, causing flashing around chimneys, vents, and skylights to pull away. We fix this by carefully removing the compromised flashing, preparing the surface, and installing new, corrosion-resistant flashing with durable sealants designed for our coastal environment to prevent future separation.

Signs include higher energy bills, musty odors in the attic, or visible water stains. On Saint Helena Island, warm, humid air entering the attic can condense on cooler surfaces, soaking insulation and reducing its effectiveness. This moisture can also lead to mold and wood rot. We perform attic inspections to identify the source—often inadequate ventilation or a leak—and remedy it before replacing damaged insulation.

We start with a thorough inspection to find the root cause, like a leak at a flashing point that allowed water to travel and wet the insulation. We then repair or replace the flashing to stop the water entry. Next, we assess and address any attic ventilation issues to prevent future condensation. Finally, we remove any wet, compromised insulation and replace it to restore your home's thermal barrier and air quality.
