Such policies are "all-risk" policies, which cover everything except earthquakes, floods, war and nuclear accidents.

A basic policy can be expanded to include additional coverage, such as for floods and earthquakes and even workers' compensation for servants or contractors. Home-based business-coverage, an increasingly popular rider, does not cover liability associated with the business.

Insurance experts recommend that homeowners obtain insurance equal to the full replacement value of the home. On a 2,000-square-foot home,for example, if the replacement cost is $80 per square foot, the house should be insured for at least $160,000.

For personal items, homeowners can increase their coverage beyond the depreciated value of items such as televisions or furniture by purchasing a "replacement-cost endorsement" on personal property.

Some experts recommend an inflation rider, which increases coverage as the home increases in value.
