Have your chimney flashing (the seal between the chimney and the roof) inspected and maintained. Flashing prevents rain water and snow melt from entering your home and causing costly damage to your walls and ceilings.
More extensive flood prevention means constructing barriers to prevent floodwaters from entering your home. This process involves building a levee out of compacted earthen structure or engineering a structure out of concrete or masonry.
The advantages of a flood barrier include: No significant changes to your home. The home can be occupied during construction. Levees or floodwalls reduce the risk of flood damage to your home.
