FAQs
What are the most common reasons roof decking starts to sag in La Follette?
In our area the main culprits are prolonged moisture intrusion, age-related wood fatigue, inadequate ventilation, and heavy wind-driven rain or snow loads. When shingles fail or flashing is damaged, water seeps through to the plywood or plank decking. Over time the wood swells, loses structural strength, and begins to bow between the rafters. La Follette’s humid summers and freeze-thaw winters accelerate this cycle, while early cabins and older homes may also have undersized rafters or spaced sheathing that no longer meets code.
How can I tell if my roof deck is sagging and needs professional repair?
Look for a dip or uneven line when you sight across the roof ridge from the ground. Inside the attic, check for daylight coming through nail holes, soft or spongy areas you can press with a broom handle, or mold and dark staining on the underside of the decking. Ceiling cracks, new nail pops, and shingles that buckle or wrinkle are other red flags. If you see any of these signs, schedule an inspection quickly—walking on a compromised deck can be dangerous.
What happens if I delay fixing a sagging roof deck?
Postponing repairs lets moisture spread to adjacent panels and framing, turning a localized patch job into a full tear-off. The sag deepens, stressing rafters and trusses, and can eventually cause partial collapse. Indoors you may face ceiling leaks, ruined insulation, higher energy bills, and possible electrical hazards if water reaches wiring. Mold growth can also trigger respiratory problems for occupants. Early intervention almost always saves money and preserves more of the original structure.
What does the repair process involve when you service a sagging deck?
1) Inspection: We document moisture levels, structural integrity, and the extent of rot. 2) Tear-off: Shingles, underlayment, and damaged decking sections are removed down to solid wood. 3) Framing correction: We sister or replace weakened rafters and ensure proper spacing and load capacity to meet current Tennessee building codes. 4) New decking: Code-approved 7⁄16" or 5⁄8" OSB or plywood is installed with staggered seams and proper fasteners. 5) Ventilation upgrade: Adding ridge vents or soffit vents prevents future moisture buildup. 6) Re-roofing: Waterproof underlayment, flashing, and new shingles or metal panels finish the system. Most residential projects take one to two days depending on size and complexity.
How much should I budget to repair sagging roof decking in La Follette?
Costs vary with slope, access, material choice, and how much decking and framing must be replaced. Minor localized repairs may start around $1,500–$2,500. A mid-sized home needing 3–5 squares of new decking often runs $3,500–$6,000. Full replacement during a re-roof can range from $8,000–$12,000 or more. We provide a free on-site estimate, explain options, and always look for ways to save clients money without compromising safety.
Will my homeowner’s insurance cover sagging roof deck repairs?
Coverage depends on the cause of damage and your specific policy. Sudden events—such as a fallen tree limb or windstorm that punctures the roof—are usually covered. Gradual deterioration from age, lack of maintenance, or long-term leaks is typically excluded. We can document storm damage, take photos, and help you file a claim if it qualifies. Even when decking replacement isn’t covered, insurance may still pay for interior water damage, so it’s worth reviewing your policy and asking your agent.
