Understanding Roof Decking Rot Repair: Partial vs Full Replacement Decision
Rotten roof decking discovered during reroofing—the most common unplanned cost. Replace individual sheets ($60-100 per 4x8 sheet labor + material) vs full re-decking ($1.50-3.00/sq ft). Soft spots smaller than 3 feet across can be spot-repaired; widespread rot (30%+ of deck affected) or delaminating plywood requires full replacement. Always photograph rotted areas before covering with new shingles for insurance documentation.
Your roof is your home's first line of defense against the elements. Making informed decisions about roofing materials, maintenance, and when to repair vs replace can save you tens of thousands of dollars over your homeownership journey.
