Roof Decking Replacement Services We Provide
Our roof decking replacement services address every aspect of your roof's structural foundation, from initial inspection through final material installation and quality verification. We handle complete deck replacements, partial section repairs, emergency water damage restoration, and preventive maintenance that extends the life of your entire roofing system.
Complete Roof Deck Tear-Off and Replacement
We remove your old, damaged roof decking completely and install new plywood or OSB sheathing that provides a solid foundation for your roofing materials. Our crews carefully strip away deteriorated deck sections while protecting your home's interior from debris, dust, and weather exposure during the replacement process.
We inspect the underlying rafter structure for rot, pest damage, or structural issues that could compromise your new deck's performance and stability. Our complete replacement service includes proper fastener spacing, moisture barrier installation, and immediate weatherproofing to keep your home safe throughout the project timeline.
Partial Roof Deck Section Repair
We replace only the damaged or rotted sections of your roof deck, which saves you money while restoring structural integrity to compromised areas. Our technicians identify problem zones through thorough visual inspections and moisture meter readings that reveal hidden water damage beneath your existing roofing materials.
We cut out deteriorated plywood or OSB panels precisely and install matching-thickness materials that create a seamless, level surface for your new roof. This targeted approach works perfectly for localized damage from leaks, storms, or ventilation problems that haven't affected your entire roof deck structure.
Emergency Roof Deck Repair Services
We respond to emergency calls within four hours when storm damage, fallen trees, or sudden leaks expose your roof deck to weather and threaten interior damage. Our rapid response team arrives with materials, tools, and tarps to immediately protect your home while we assess the extent of deck damage.
We provide temporary weatherproofing and structural support before completing permanent roof deck replacement once conditions allow safe, quality work to proceed properly. Our emergency service includes 24/7 availability, direct insurance company coordination, and documentation photography that supports your claim process and speeds up your reimbursement timeline.
Roof Deck Upgrade and Reinforcement
We strengthen your existing roof deck structure by adding thicker plywood panels, additional fasteners, or reinforcement blocking that meets modern building codes. Our upgrade service works especially well for older homes with thin or inadequately secured deck materials that don't meet current wind resistance standards.
We can increase your roof's load-bearing capacity for heavier roofing materials like tile or slate while improving overall structural performance and longevity. This proactive approach prevents future damage, reduces insurance premiums, and adds measurable value to your property when you decide to sell or refinance.

Engineered OSB Roof Sheathing Systems
We use structural-grade OSB for strength, stability, and cost-effective performance. Water-resistant coatings and engineered strands protect against moisture and splitting.
Specialty Decking for Unique Applications
We install tongue-and-groove, fire-rated, pressure-treated, or marine-grade plywood as needed. This ensures stability, protection, and long-term roof performance in any environment.

Roof Decking Replacement FAQs
How long does roof decking replacement typically take to complete?
Most residential roof deck replacements take two to five days, depending on roof size, damage, and weather. We work efficiently to ensure quality installation, proper fastening, and full weather protection while minimizing disruption.
What causes roof decking to deteriorate and need replacement?
Decks deteriorate from water leaks, poor attic ventilation, storm damage, age, or improper installation. Damage often occurs near chimneys, valleys, and skylights where moisture concentrates and flashing may fail.
Can you replace just part of my roof deck, or does the entire deck need replacement?
We can replace only damaged sections when deterioration is localized, saving money and restoring structural integrity. Full replacement is recommended only for widespread damage, code violations, or severely outdated materials affecting over 40% of the roof.
What thickness of plywood or OSB do you recommend for roof decking?
We typically use 5⁄8-inch plywood or OSB for standard 24-inch rafter spacing with asphalt or metal roofs. Heavier materials like tile require ¾-inch decking, while 16-inch rafters can use ½-inch, always following California codes and manufacturer specifications.
How much does roof decking replacement cost for an average home?
Costs generally range from $4 to $8 per square foot, depending on materials, damage, and accessibility. A 2,000-square-foot roof typically costs $8,000–$16,000, including materials, labor, permits, and disposal, with transparent estimates provided upfront.
