Duncan Roofing & Siding | Roofing Services in Mounds, OK 74047

Common signs in our area include sagging roof lines, dark spots or streaks on your ceiling inside the home, and a spongy feeling when walking on the roof. Often, decking rot starts from persistent moisture trapped by damaged underlayment or from past storm damage. We recommend a professional inspection, as the problem isn't always visible from the ground and early detection prevents more extensive structural issues.

The underlayment is a critical water-resistant barrier installed directly on your roof deck. In Mounds, with our heavy rains, hail, and wind, it acts as a last line of defense if shingles are compromised. When underlayment is damaged or aged, water can seep through to the decking, leading to rot, mold, and interior leaks. Our repairs ensure this vital layer is intact to protect your home's structure.

Our process starts with a detailed inspection to assess the full extent of the damage. We then carefully remove the affected shingles to expose the decking. Any rotted or compromised wood is replaced with new, sturdy decking. Next, we install a fresh, high-quality synthetic underlayment for superior protection before re-shingling the area to match your existing roof. This targeted repair addresses the root cause to prevent recurrence.
