Roof sheathing rot — Alicante, Valencian Community
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.
Waarom dit veel voorkomt in Alicante
The Mediterranean climate's combination of intense UV, occasional intense rainfall, and salt air creates specific roofing challenges. Flat terraced roofs (azoteas) are common and prone to waterproofing failure as membranes age. The rainy season (October–December) exposes latent leaks after the dry summer. Coastal properties need salt-resistant flashing and fixings.
