Roof sheathing rot — Fresno, California
Roof sheathing (the plywood or OSB boards nailed to the rafters beneath shingles) can rot when moisture becomes trapped — from a slow leak, poor attic ventilation, or ice dams pushing water under shingles. Soft, spongy spots on the roof surface, sagging between rafters visible from the attic, or dark water stains on sheathing boards are all signs of rot. A roofer can assess the extent of damage, replace affected sheathing panels ($70–$100 per sheet plus labor), and address the moisture source to prevent recurrence.
