Barnard Roofing | Roofing Services in Johnson City, TN 37615

In our Johnson City climate, roof deck rot is primarily caused by moisture intrusion from worn shingles, ice dams, or poor attic ventilation, which leads to wood decay. Nail pops are often the result of the natural expansion and contraction of roof framing and sheathing due to our seasonal temperature swings and humidity. Both issues can compromise your roof's integrity and lead to leaks if not addressed promptly by a local roofing professional.

Our inspection starts in your attic, looking for signs of moisture, dark wood stains, or soft spots in the decking. From the exterior, we check for sagging lines or spongy areas. If rot is found, we carefully remove the affected shingles and underlayment to replace the rotten decking with new, treated plywood or OSB. We then re-install high-quality underlayment and shingles, ensuring proper sealing to prevent future moisture issues specific to our area's weather.

Yes, often we can. For isolated nail pops, we carefully remove the affected shingle, extract the popped nail, and secure the decking with a new, corrosion-resistant nail in a slightly different location before resealing and re-adhering the shingle. However, widespread nail popping can indicate underlying movement or an aging roof system. We'll provide an honest, local assessment to determine if targeted repairs are sufficient or if a more comprehensive solution is needed to ensure your home's long-term protection.
