Cost to Redeck a Roof: A Comprehensive Guide: 1 Minute to Understand Your Redecking Investment

Redecking a roof is a significant home improvement investment, often necessary when the existing roof decking becomes damaged due to leaks, rot, or aging. The cost to redeck a roof depends on several factors such as the type of decking material, roof size, labor charges, location, and additional repairs required. Typically, homeowners can expect to pay between $2,000 and $7,000 for a full redecking project, with costs varying based on the complexity and scale of the job.

Material Costs: The most common roof decking materials include plywood and OSB (Oriented Strand Board). Plywood is generally more expensive, averaging between $30 and $50 per sheet, while OSB costs about $25 to $40 per sheet. The number of sheets required depends on your roof’s square footage—most residential roofs need dozens of sheets.

Labor Costs: Skilled roofers typically charge $2 to $5 per square foot for redecking, with labor rates increasing in regions with higher living costs. Complex roof structures, steep pitches, or unique architectural features can increase labor expenses.

Additional Costs: Removing old roofing materials, handling structural repairs, or upgrading underlayment and insulation will add to the overall budget. Disposal fees for old decking and special treatments—such as waterproofing—also factor into total expenditures. Unexpected finds during demolition, like hidden rot or pest damage, can further escalate costs.

Design Consideration: As a designer, I recommend approaching redecking projects with holistic planning. Not only does redecking restore the integrity of your roof, but it’s also a valuable opportunity to rethink your home's structural layout or ceiling finish. For instance, refreshing your attic or upper floor design after redecking can dramatically improve your interior appeal. If you’re considering evaluating or planning other home improvements alongside roof upgrades, tools like a comprehensive Home Designer can help you visualize changes and optimize your investment—giving you both functional and aesthetic returns.

Tips 1:

Always request a detailed quote from several roofing contractors and require a thorough inspection before proceeding. This helps prevent budget surprises and ensures your redecking work addresses all problems. Consider using moisture barriers or enhanced insulation, especially if you live in a wet or cold climate, to maximize the lifespan and performance of your new roof decking.

FAQ

Q: What is roof redecking?

A: Roof redecking involves removing the old decking material (typically plywood or OSB) and installing new boards to provide a secure base for shingles or other roofing materials.

Q: How long does redecking a roof take?

A: Most residential roof redecking projects take 1–3 days, but the timeline can extend for larger homes or complex roofs.

Q: How can I tell if my roof needs redecking?

A: Signs include sagging roof areas, persistent leaks, visible rot, mold, or water damage in the attic or ceilings.

Q: Is redecking covered by homeowners insurance?

A: If damage is caused by a covered peril (like a storm), insurance may help. However, general wear and tear is rarely covered.
