Wet-Season Home Care: Simple Checks for a South Florida Home

South Florida's rainy season runs from mid-May to mid-October, when most of the year's rain falls. A few hours of simple home checks before and during the season protect the roof, the drains, and the budget.

In South Florida, the rainy season officially runs from May 15 to October 15, the roughly five months when the region receives most of its yearly rainfall. That calendar is also the home care calendar. None of the checks below needs a contractor; they take an hour, a ladder, and the habit of doing them early in the season. Home care in a community listens to the weather: you work ahead of the rain, not against it.

Start at the top: the roof and the gutters

The roof and the gutters direct most of a tropical summer. Check for missing or lifted tiles, and prune any branch that touches the house. Clean the gutters and downspouts at least twice during the season, and point the downspouts well away from the foundation. A clogged gutter can turn days of rain into a slow leak, and a slow leak is the most expensive repair to discover late.

Walk the yard the day after a storm

The day after a normal rain, walk the property in shorts and you will see what the dry season hides: the low spots where water stands against the wall, the flat areas that hold puddles for days, and the downspout ends that stopped sinking. If you see the same wet spot near the foundation twice, fix the grade or the drain this season, before it becomes an inside conversation.

Give the air conditioner its seasonal visit

Heat and rain together make humidity, and the air conditioner does the quiet work of the whole wet season. Clean or replace the filter when the season begins, and check that the condensation drain runs to the outside instead of dripping where it should not. A dry, comfortable house feels better and will probably cost less in energy than a house that runs a struggling unit.

Close the small openings before water finds them

In a tropical city, water does not need a big opening. Review the seal on the sliding glass doors, the weather stripping on the main doors, the gap under the garage door, and the caulk around the windows and the lanai. A tube of caulk and a strip of weather sealing cost little; the stains and bugs they avoid cost real money. It is the least dramatic maintenance item, andfamilies feel it all day.

Know your flood zone before the storm

Flood damage is not covered by a standard homeowners policy; it takes a separate policy, andflood policies carry a waiting period before they take effect. Check the flood zone of any address you own or are considering, talk to your insurance agent at the start of the season, anddecide with time. The zone of your address does not change, but your preparation calendar does, so make the call in the calm months, not during the storm.
