The cost to replace roof decking (or sheathing) varies significantly based on material, roof size, and location. On average, homeowners can expect to pay between $1.50 and $3.50 per square foot for the decking material alone, with plywood or OSB being common choices. Labor for removal and installation typically adds another $2 to $5 per square foot. For a standard 2,000 sq. ft. roof, total costs often range from $7,000 to $17,000. This is a major structural repair, so it's crucial to get multiple detailed quotes from licensed contractors who will inspect for underlying damage.

To repair damaged roof decking, first conduct a thorough inspection to assess the extent of the damage, looking for soft spots, rot, or water stains from inside the attic. Safety is paramount; ensure proper support and use fall protection. Remove the shingles and underlayment over the affected area. Cut out the damaged plywood or OSB sheathing using a circular saw, being careful not to cut into the rafters. Install new decking material of the same thickness, securing it to the rafters with appropriate nails or screws, following local building codes. Replace the underlayment and roofing materials, ensuring proper sealing at seams. This repair is critical as compromised decking undermines the entire roof structure and can lead to major leaks. For extensive damage, consulting a professional roofer is strongly recommended.
The cost of roof repairs varies significantly based on the extent of damage, materials, and your location. Minor repairs like fixing a few shingles or sealing a leak might cost between $150 and $400. More extensive repairs involving underlayment or structural issues can range from $1,000 to $3,000 or more. It's crucial to obtain multiple detailed estimates from licensed, insured contractors. These should include a breakdown of labor, materials, and warranty. Avoid unusually low bids, as they may indicate subpar materials or workmanship. Investing in quality repairs protects your home's value and prevents more costly damage from water intrusion. Always ensure the estimate is in writing before work begins.
Insurance coverage for new roof decking depends on the cause of damage. Most homeowners insurance policies cover decking replacement if the damage is sudden and accidental, such as from a storm, falling tree, or fire. However, if the decking is deteriorated due to wear and tear, age, or lack of maintenance, it is typically not covered. The insurance adjuster will inspect to determine the cause. Always document the damage with photos and file a claim promptly. It is crucial to review your policy details and work with a reputable roofing contractor who can provide a thorough assessment for the insurance company.
