Clean out eavestroughs and downspouts
It doesn't take much water to produce localized flooding, and when a home isn't adequately prepared, the chances of damage are all but certain. Simple steps that you can do to soften the impact include cleaning out gutters and drains so that precipitation will channel away. Make sure that the downspouts are clear as well and faced outward.
If you live in a low-lying area, there's an increased likelihood that floodwaters could penetrate your home's interior. If you have transportable belongings and flooding is forecasted, move them to someplace where water can't get to them. Bear in mind, however, that you don't necessarily have to live in a flood zone to be at risk for one. According to FEMA data, nearly 1 in 5 flood insurance claims are outside of flood zone areas.
Reinforce your roof
You may not think of your roof as a flood deterrent, but a leaking roof can lead to water damage. HouseLogic recommends that the next time your roof needs to be replaced - an asphalt-shingled roof usually lasts approximately 25 years -consider installing waterproofing material underneath the shingles. This makes it harder for rainwater to leak in, potentially damaging the interior walls or ceiling.
Purchase flood insurance
Help protect yourself and your home by buying flood insurance. According to FEMA's estimates, over 5.3 million people in the U.S. have a flood policy in place through the National Flood Insurance Program. With flood insurance protection, you won't have to worry about paying massive amounts for repairs.
