Covington stands out as one of the nation’s most water disaster-prone communities, with a remarkable 47 federally recognized water emergencies recorded in St. Tammany County. This figure alone highlights a persistent and multifaceted threat from water intrusion. Situated in a gulf subtropical climate, Covington receives an average of 66.2 inches of rainfall annually, considerably surpassing the typical U.S. range of 30 to 40 inches. This excess moisture fosters both acute flood events and chronic dampness problems, complicating efforts to keep homes dry and safe.
The dominant water-related hazard remains hurricanes and tropical storms that batter the region from June through October, often delivering intense rainfall and storm surge that overwhelm drainage systems. Secondary but equally persistent threats include flash floods triggered by sudden downpours and the region’s characteristic high humidity, which accelerates building material deterioration. Homeowners frequently report roof leaks during storms, HVAC condensation backup, and sewage overflows during flooding events, all of which exacerbate water damage risks.
Flood zone designations in Covington are considered extreme, meaning many neighborhoods lie within areas highly susceptible to inundation. This status informs insurance requirements and underscores the importance of flood-prepared construction and landscaping. Even outside peak hurricane months, the city experiences water intrusion through failed window seals and slab foundation cracks, driven by the constant moisture saturation from the environment.
Understanding Covington’s specific water damage profile helps clarify why residents face ongoing challenges. The combination of frequent disasters, high precipitation, and geographical vulnerability creates a situation where water damage is not a rare emergency but a recurring hazard requiring vigilant preparation and swift response.
With 47 FEMA water disaster declarations, St. Tammany County has a significant history of federally-declared water emergencies.
St. Tammany County has been at the epicenter of water-related emergencies with a striking total of 47 federally recognized water disasters. This figure significantly outpaces the national average for counties, which generally experience between 8 and 12 such events. This elevated frequency positions Covington’s community among the most disaster-prone regions in the United States, underscoring a persistent vulnerability to water damage. The breadth of events includes 32 hurricane-related emergencies and 9 flood-specific declarations, illustrating the dual threat of storm surges and inland flooding that residents must prepare for.
The pattern of disaster declarations accelerates when viewing recent history: since 2010 alone, the county has endured 21 federally declared water emergencies. This uptick reflects either increased storm activity or heightened recognition and reporting of damage, but either way, it signals that the threat is neither distant nor diminishing. Most recently, in 2024, Covington faced another federally declared water crisis, reinforcing that water damage is a current and pressing concern rather than a historical footnote.
Covington’s location in a gulf subtropical climate zone means it regularly endures intense hurricane seasons and heavy rainfall, both of which contribute to its federal disaster tally. Homeowners should consider this history a clear indicator of ongoing risk, not just something to note in passing. The frequency and scale of these emergencies suggest that water intrusion events can strike repeatedly within a typical homeowner’s tenure, making proactive mitigation and swift response essential components of property management in St. Tammany County.

Yes — you may select your own restoration contractor rather than your insurer's preferred vendor.
The first 60 minutes after water damage are critical. Here's exactly what to do — and what to avoid.
Shut off the main water valve if it's a pipe. If it's storm-related, move to step 2. Don't enter standing water near electrical outlets.
Turn off breakers to any room with standing water. If the breaker panel is in the flooded area, call your utility company first.
Photograph and video all damage before touching anything. Your insurance claim depends on evidence of initial conditions.
Don't wait. In Covington's climate, mold begins colonizing within 24–48 hours. The faster pros start extraction, the lower the total cost.
Move electronics, documents, and irreplaceable items to dry areas. Lift furniture off wet carpet with aluminum foil under the legs.
What should a Covington homeowner do immediately after spotting water intrusion? In the first 24 to 48 hours following discovery, prompt action is critical to prevent escalating damage and health risks, especially in the city’s humid subtropical climate where mold can begin colonizing in less than two days. Safety tops the list: if standing water is near electrical outlets or appliances, cutting power to affected areas can prevent shock or fire hazards. Structural stability should also be assessed—signs of sagging ceilings or warped floors mean evacuation may be necessary.
Next, shutting off the water source—whether from a leaking toilet supply line, a ruptured water heater, or storm runoff—is crucial to stop further flooding. Containment measures, like deploying towels or temporary barriers, help limit spread while professional assistance is arranged. During this window, thorough documentation through photos and video of the damage supports insurance claims and helps quantify losses for recovery budgeting.
Deciding what to salvage immediately versus what to leave for restoration experts relies on the type of water involved and local conditions. Clean water exposure may allow quick drying of certain personal items, but floodwaters often carry contaminants requiring disposal. Since mold growth can initiate within approximately 48 hours in Covington’s moist environment, delaying drying efforts increases the risk of secondary damage. Thus, while homeowners can start initial cleanup measures, bringing in experienced professionals ensures thorough moisture removal and mold prevention.

Many Covington homeowners assume water damage repair costs are either negligible or catastrophic extremes, but local data reveals a more nuanced financial landscape. Minor incidents, such as a faulty washing machine hose leaking into a laundry room, typically range from $1,200 to $5,100 in restoration expenses. Moderate damage, often the result of more pervasive issues like a slow roof leak during hurricane season affecting multiple rooms, runs between $5,100 and $15,200. Major damage, stemming from severe flooding or a ruptured water heater flooding an entire floor, can climb to $50,600. This upper range represents about 17.4% of the median home value in Covington, which stands around $291,112.
The local labor market and material costs slightly elevate expenses compared to national averages, with a cost multiplier of 1.01. While this difference may seem minimal, it reflects regional economic realities that homeowners should factor into their budgeting. For instance, replacing drywall and flooring after persistent HVAC condensation issues in Covington’s humid climate may push costs toward the moderate range, especially when mold prevention measures extend drying times and require specialized equipment rental.
Understanding these tiers helps residents plan realistically. A substantial repair bill equivalent to roughly eight months of median household income ($75,851) is a significant financial event but not insurmountable with foresight and insurance planning. Covington’s moisture challenges mean that even seemingly small leaks can escalate without prompt attention, so budgeting for timely maintenance and occasional restoration is prudent. In this climate, proactive maintenance and early intervention can substantially reduce the frequency and severity of costly repairs.
Humidity is the hidden accelerator in water damage. In Covington, ambient moisture levels make professional drying equipment essential.
Many Covington residents underestimate how rapidly mold can thrive after water intrusion, a misconception that leaves homes vulnerable. Given the area’s gulf subtropical climate and annual precipitation exceeding 66 inches, mold spores find ample opportunity to colonize within 24 to 72 hours after moisture exposure. This accelerated timeline is compounded by Covington’s high humidity, which prolongs drying periods by 30 to 50 percent compared to drier regions, enabling mold to infest hidden spaces such as wall cavities and subflooring.
The local environment’s sustained moisture challenges mean that even minor leaks or condensation from HVAC systems can evolve into significant mold issues if not addressed promptly. Unlike arid climates where mold risk is confined mostly to visible wet areas, Covington’s ambient humidity creates a pervasive threat that can affect indoor air quality and lead to respiratory irritation, especially for sensitive individuals including children and those with asthma or allergies.
Preventing mold growth here demands a combination of strategies tailored to the climate: ensuring adequate ventilation in attics and crawl spaces, deploying dehumidifiers to manage indoor moisture levels, and conducting professional moisture assessments to detect concealed dampness. These measures often involve extended equipment rental and increased labor due to the difficulty of drying in such a humid zone. Recognizing the local mold threat helps homeowners prioritize timely intervention and maintain healthier living environments.
