Climate risks for Hawaii homes
High humidity feeds mold in bathrooms, attics and crawl spaces and makes air conditioners work harder to dry the air.
Severe storms lift shingles, drive rain under flashing and push on garage doors. Wind-rated materials and solid nailing patterns pay off here.
Heavy rain and flooding soak floors, drywall and foundations. Standard homeowners policies exclude flood, so check your coverage.
