How Can I Prepare My Home for Spring Storms and Heavy Rain?
Spring storms can combine heavy rain, strong wind, lightning, hail and rapid changes in temperature. Preparing before the storm may reduce the risk of overflowing gutters, foundation seepage, roof damage, sewer backups, falling branches and water entering through vulnerable exterior openings.
What should you check before a spring storm?
Inspect gutters, downspouts and ground-level drains from a safe location. Make sure downspouts discharge away from the foundation and that soil, patios and walkways are not directing water toward the house.
Look from the ground for loose roofing, damaged siding, open exterior penetrations and branches that could strike the home. Secure outdoor furniture, grills, decorations, tools and other objects that strong wind could move.
Charge phones, prepare flashlights, review emergency alerts and know where to shelter. Do not enter floodwater, touch downed power lines or inspect the roof during or immediately after severe weather.
Start by identifying the storm risks around your property
Different homes face different storm risks. A house at the bottom of a slope may be vulnerable to surface runoff, while a home with mature trees may face greater wind and branch hazards.
Review what happened during previous storms. Note where water pooled, which gutters overflowed, whether basement walls became wet and whether any rooms developed stains or leaks.
Also consider nearby drainage ditches, creeks, storm drains, retaining walls, slopes and low roadways. Conditions beyond the property line may influence how quickly water reaches the home.
Water collects beside the foundation or near a basement window.
Gutters overflow or downspouts discharge near the house.
Large branches extend over the roof, driveway or power lines.
The property has flooded, lost power or experienced sewer backup during earlier storms.
Photos and notes from earlier weather events can reveal recurring drainage and exterior weaknesses that may not be obvious on a dry day.
Make sure gutters and downspouts can move roof water away
A roof can collect a large volume of water during a short storm. Gutters and downspouts need open pathways and stable connections to move that water away from walls, doors and the foundation.
Look for visible gutter debris
Leaves, seed pods, roof granules and other material may restrict water flow and contribute to overflowing.
Check downspout connections
Loose elbows and separated sections can release concentrated water against siding or the foundation.
Confirm discharge moves away from the house
Short or missing extensions may allow roof water to collect directly beside the foundation.
Look for sagging or incorrectly sloped sections
Standing water in a gutter may indicate inadequate slope, loose fasteners or deformation.
Check underground discharge outlets
Buried downspout systems may back up when outlets are blocked, crushed or submerged.
Look for staining behind the gutter
Stains on fascia or siding may indicate that water has been moving behind or over the gutter during previous rain.
Wet roofs, unstable ladders and approaching wind increase fall risk. Arrange qualified gutter or roofing service when cleaning or repairs require elevation.
Check whether surface water can move away from the home
Heavy rain can overwhelm low areas and expose drainage patterns that remain hidden during ordinary weather. Water should not be intentionally directed toward neighboring properties, public roads or unstable slopes.
Soil may slope toward the foundation
Settlement and landscaping changes can create low areas where water collects beside walls.
Mulch or soil may be too high against the exterior
Raised beds can trap moisture against siding, masonry and foundation openings.
Patios and walkways may direct runoff inward
Settled concrete or paving can route water toward doors, basement windows and foundation joints.
Yard drains may be covered or blocked
Leaves, sediment and landscaping material can restrict accessible drain grates and inlets.
Drainage swales may have been altered
Fences, sheds, gardens and fill soil can interrupt intended surface-water pathways.
Sump discharge may return toward the house
A short, blocked or poorly positioned outlet can allow pumped water to flow back toward the foundation.
A dry-weather adjustment does not always perform as expected. Observe from indoors or another safe location and confirm where the water actually moves.
Look for exterior openings and materials vulnerable to wind or rain
Wind-driven rain can enter through small exterior defects that may not leak during light vertical rainfall.
Look for loose or missing roof materials from the ground
Lifted shingles, displaced flashing and damaged roof edges may allow water entry during strong wind.
Check siding and trim
Loose panels, open joints and damaged trim may allow water behind the exterior surface.
Inspect accessible window and door seals
Failed weatherstripping, gaps and deteriorated exterior sealant may allow drafts and wind-driven water.
Check basement window wells
Leaves, soil and damaged covers can reduce available drainage and allow water to build against the window.
Look around exterior penetrations
Utility lines, vents, hose faucets and other wall openings may have visible gaps or damaged flashing.
Check garage and exterior doors
Damaged bottom seals and low thresholds may allow wind-driven water into garages and entry areas.
Some exterior systems contain weep holes, vents and drainage gaps. Sealing an opening without understanding its purpose may trap water inside the wall assembly.
Secure objects that wind could move or turn into hazards
Even moderate outdoor items can damage windows, siding, vehicles and neighboring property when lifted or rolled by strong wind.
Bring lightweight furniture indoors
Move chairs, cushions, umbrellas and small tables into a protected location before wind begins.
Secure grills and outdoor cooking equipment
Follow the manufacturer’s storage and fuel-safety instructions. Do not move hot equipment or bring fuel cylinders into living areas.
Store tools and garden equipment
Shovels, rakes, watering cans and loose materials can become windblown hazards.
Retract awnings and umbrellas
Use the manufacturer’s storm instructions and avoid handling large covers once wind has started.
Check temporary structures
Canopies, tents, portable greenhouses and lightweight sheds may require removal or secure anchoring.
Move vehicles away from obvious tree hazards
Use a safer available location when dead limbs or damaged trees threaten the usual parking area.
Do not remain outside moving furniture or inspecting trees after lightning, severe wind or flash-flood conditions begin.
Prepare basements, crawlspaces and other low areas
The lowest areas of a home may show drainage, sewer and groundwater problems first. Preparation should prioritize safety and reducing damage rather than entering hazardous spaces during flooding.
Test accessible sump-pump operation
Follow the manufacturer’s instructions and do not reach into a wet pit or touch electrical equipment with wet hands.
Check the sump discharge path
The outlet should not be visibly disconnected, blocked or returning water toward the foundation.
Review backup-power arrangements
Battery or generator backup systems should be maintained and operated according to their instructions.
Move valuable items above floor level
Use shelving or another stable elevated location for documents, electronics and irreplaceable items.
Check the lowest plumbing fixtures
Floor drains, showers and toilets may show sewer backup before higher fixtures do.
Keep pathways and shutoffs accessible
Avoid storing items around the electrical panel, main water shutoff, sump equipment and emergency exits.
Floodwater may contain sewage, chemicals and hidden electrical hazards. Wait for qualified authorities or professionals to determine whether entry is safe.
Prepare for power, water and communication interruptions
Severe storms can interrupt electricity, internet, municipal water, private wells, sump pumps and refrigeration. Basic preparation can reduce rushed decisions during an outage.
Emergency alerts
Enable reliable weather alerts and know the difference between watches, warnings and evacuation instructions.
Lighting
Keep flashlights, lanterns and appropriate batteries available.
Phone power
Charge mobile phones and portable power banks before the storm.
Water and food
Store appropriate drinking water and food that can be prepared safely during an outage.
Medical needs
Plan for medications, refrigeration needs and electrically powered medical equipment.
Generator safety
Review outdoor placement, extension-cord, transfer-equipment and fuel requirements before power is lost.
Improper connection can energize utility lines and create deadly risks for occupants and utility workers. Use approved equipment installed and operated according to applicable requirements.
What to do while severe weather is occurring
Once severe weather begins, personal safety takes priority over property inspection. Conditions can change faster than a drainage or roofing problem can be safely corrected.
- Follow official weather alerts, evacuation orders and shelter instructions.
- Stay indoors and away from windows during severe wind and hail.
- Use an appropriate interior shelter location for tornado warnings.
- Avoid using corded electrical equipment during nearby lightning.
- Do not climb onto the roof or use ladders during wind or rain.
- Do not walk or drive through floodwater.
- Stop unnecessary water use if drains begin backing up.
- Keep children and pets away from wet basements and exterior flooding.
- Report downed power lines and keep everyone far away.
Water flow can be documented later. Lightning, falling branches, windblown debris and flash flooding create immediate hazards.
Warning signs that require immediate or prompt attention
Storm damage can create electrical, structural, contamination and utility hazards. Some conditions require evacuation or emergency assistance rather than homeowner investigation.
Leave the area and seek appropriate help when:
- Floodwater is entering the home rapidly.
- Water reaches outlets, appliances, wiring or the electrical panel.
- A ceiling, wall or roof section appears to be collapsing.
- You smell gas, fuel, burning insulation or chemicals.
- A tree or large branch damages the roof or utility service.
- Downed power lines are present on or near the property.
- Sewage backs up into the home or appears outdoors.
- Local authorities issue an evacuation or flash-flood warning affecting your location.
- Water pools against the foundation during ordinary rainfall.
- Gutters overflow from multiple locations.
- Basement walls or floors become wet after most storms.
- A sump pump runs continuously or cannot keep up.
- Roof, siding or window leaks return during wind-driven rain.
- Drains gurgle or slow when rainfall becomes heavy.
- New cracks, movement or erosion appear after runoff.
What to document before and after a storm
Photos and notes can help contractors, utilities and insurance representatives understand what changed and where water or wind affected the property.
Pre-storm condition
Photograph roofing, siding, gutters, trees and vulnerable interior areas from safe locations.
Water pathways
Record where downspouts discharge and where yard runoff usually collects.
Rain and weather timing
Note when rainfall became heavy and when leaks or pooling first appeared.
Interior damage
Photograph stains, wet materials, floor water and damaged contents without entering unsafe areas.
Exterior damage
Document fallen branches, loose materials and visible damage from the ground.
Utility interruptions
Record power, water, sewer, gas and communication outages.
Emergency actions
Note shutoffs, temporary protection and calls made to utilities or emergency services.
Previous repairs
Gather invoices and warranties for roofing, drainage, sump, window and exterior work.
Do not delay emergency water control or place yourself in danger, but basic documentation may help explain the original condition before cleanup begins.
When professional evaluation may be appropriate
The right professional depends on whether the concern involves roofing, drainage, trees, electricity, plumbing, sewage or structural damage.
Roofing professional
Roofing evaluation may be appropriate for missing materials, storm-created openings, flashing damage and interior leaks.
Drainage or foundation professional
Evaluation may help when runoff repeatedly reaches the foundation, basement or crawlspace.
Licensed plumber or sewer professional
Plumbing help may be appropriate for backups, damaged sump systems, broken pipes and recurring drain problems.
Qualified arborist
Tree evaluation may be appropriate for damaged limbs, leaning trees and hazards near roofs, driveways and utility lines.
Licensed electrician
Electrical evaluation is appropriate when water, wind or fallen debris affects wiring, panels, outlets or service equipment.
Water-damage or cleanup professional
Specialized drying and cleanup may be appropriate after significant rainwater, floodwater or sewage exposure.
Structural professional
Structural evaluation may be appropriate for movement, collapse, major cracking or damage to load-bearing components.
Emergency services or utility
Contact the appropriate authority for fire, gas leaks, downed lines, flooding, collapse and immediate life-safety hazards.
When conditions permit, verify licensing, insurance, scope, pricing and written authorization before approving major work.
