FAQs
How can I tell if my roof’s decking has hidden damage when the shingles still look fine?
Because decking sits beneath the underlayment and shingles, most problems are invisible from the ground. Common warning signs include a wavy or sagging roofline, soft or spongy spots you feel when walking on the roof, musty odors in the attic, water stains on ceiling drywall, or nails backing out of the shingles. A professional roofer will confirm hidden damage by lifting shingles, probing the wood with a moisture meter, and inspecting the attic for dark, deteriorating sheathing.
What typically causes hidden decking damage on homes in Decherd, TN?
In Decherd’s humid subtropical climate, moisture is the primary culprit. Wind-driven rain can seep through aging shingles, and our frequent freeze-thaw cycles cause minor cracks to widen. Inadequate attic ventilation traps warm, moist air that condenses on the underside of the decking, encouraging rot and mold. Storm debris that clogs gutters also forces water to back up under the shingle edges and soak the sheathing. Over time these conditions break down the wood fibers and compromise structural strength.
Why is it important to replace damaged decking during a roof repair rather than just patching over it?
Decking provides the structural base that fastens all roofing materials in place. Rotten or delaminated boards can no longer hold nails securely, so new shingles may blow off even after a fresh installation. Leaving compromised decking also voids most manufacturer warranties and can violate the 2018 International Residential Code adopted by Tennessee, which requires sound sheathing for any reroofing work. Replacing bad panels ensures the roof meets load-bearing standards, restores the home’s resale value, and prevents recurring leaks or interior mold growth.
Will my homeowner’s insurance cover the cost of repairing or replacing rotten decking?
Coverage depends on the policy and the cause of damage. Most insurers in Franklin County treat sudden, accidental events—such as wind, hail, or falling limbs—as covered perils. If an adjuster determines that storm water intrusion led to decking rot, they usually pay for both the damaged shingles and the sheathing beneath. However, long-term neglect, improper maintenance, or normal wear are excluded. We recommend filing a claim promptly after a storm and letting our team meet the adjuster on-site to document hidden decking decay with photos and core samples.
How long does a typical hidden-decking-damage roof repair take in Decherd?
For an average 2,000-square-foot roof, most projects are completed in one to two days. Day one involves removing old shingles, underlayment, and inspecting every sheet of decking. Any rotten or delaminated panels are cut out and replaced with 7⁄16-inch APA-rated OSB or 1⁄2-inch plywood to meet Tennessee code. Day two covers installing new underlayment, flashing, shingles, and final cleanup. Severe structural issues or specialty materials (metal, cedar) may extend the timeline by another day, but we will provide a detailed schedule before work begins.
Can you replace only the affected section of decking, or does hidden damage require a full roof replacement?
If the rot is localized—often near a chimney, valley, or roof edge—we can perform a partial decking replacement, remove just the surrounding shingles, and seamlessly weave new shingles into the existing roof. However, if more than 20–25 percent of the deck shows moisture compromise, or if the shingles are already at the end of their service life, a full tear-off and reroof is the most cost-effective solution. Our technicians will show you moisture-meter readings and photos so you can make an informed decision.
