The cost to repair roof decking varies widely, typically ranging from $1,000 to $7,000 or more, depending on the extent of damage and roof size. Key factors include the square footage of damaged decking, the type of wood (plywood vs. OSB), local labor rates, and accessibility. Minor repairs for a few sheets may cost a few hundred dollars, while widespread rot or structural issues can escalate costs significantly. It is crucial to have a professional inspection to assess hidden damage beneath shingles. For a detailed breakdown of the repair process and considerations, please refer to our internal article Roof Deck Repair. Always get multiple quotes from licensed, insured contractors.
Whether insurance covers new roof decking depends on the cause of the damage. Standard homeowners insurance policies typically cover decking replacement if the damage is sudden, accidental, and caused by a covered peril, such as a windstorm, hail, or a falling tree. However, if the damage is due to wear and tear, lack of maintenance, or gradual deterioration, it is generally not covered. The key is the adjuster's inspection to determine if the decking failure is a direct result of a covered event. Always document the damage thoroughly and review your policy's specific terms, as coverage can vary. Working with a reputable roofing contractor who can provide a detailed assessment for the insurance company is crucial.
To repair damaged roof decking, first ensure safety by using proper fall protection. The process involves removing the roofing materials (shingles, underlayment) to expose the decking. Inspect the entire area for soft spots, rot, or water damage. Cut out and replace any compromised plywood or OSB sections, ensuring the new decking is the same thickness and type. Secure it with corrosion-resistant nails, following local building codes for spacing. It is crucial to address the underlying cause of the damage, such as a leak, before reinstalling the underlayment and final roof covering. For a detailed step-by-step guide, refer to our internal resource on Roof Deck Repair. Always consider consulting a professional roofer for extensive damage to ensure structural integrity.
The frequency for redoing roof decking is not based on a set schedule but on its condition during a roof replacement. Roof decking, or sheathing, is the structural layer beneath the shingles. It typically lasts the life of multiple roofing systems if it remains dry and undamaged. The critical time for inspection is when old roofing materials are removed. If the decking shows signs of water damage, rot, mold, or structural weakness, it must be replaced at that time. Industry standards mandate replacement of any compromised sections to ensure a solid, safe substrate for the new roof. Proactive attic inspections for leaks can help preserve decking integrity between major replacements.
