Werts Roofing and Home Repair | Roofing Services in Walterboro, SC 29488

Roof deck rot is a serious issue here due to our humidity and often-hidden underlayment leaks. We start by removing the affected shingles and underlayment to fully expose the decking. Any soft, spongy, or compromised wood is completely cut out and replaced with new, pressure-treated plywood. We then install a premium synthetic underlayment for superior moisture protection before re-shingling. This process stops the rot from spreading and restores a solid foundation for your roof.

In Walterboro, underlayment often fails before shingles show major wear. Key signs include interior water stains on ceilings or walls, a musty smell in your attic, or granules from shingles collecting in your gutters. From the outside, you might notice curling or buckling shingles, as the compromised underlayment beneath them can't provide a stable base. If you see any of these, it's time for a professional inspection to prevent further damage to the roof deck.

The underlayment is your roof's secondary water barrier and is crucial in our climate with heavy rains and high humidity. When it fails, water seeps directly onto the roof deck (the plywood), leading to rot, mold, and structural weakening. Simply replacing shingles over damaged underlayment won't solve the problem. We focus on repairing the entire system—deck, underlayment, and shingles—to ensure your home is sealed against moisture, which is the most common threat to roofs in the Lowcountry.
