The short answer

Inspect Your Roof and Gutters

Your townhouse roof takes the first hit in a storm. Look for missing or loose shingles, cracked flashing, or worn seals around vents and skylights. If you can see daylight through the attic, that is a sign of trouble.

Clean gutters and downspouts before heavy rain. Clogged gutters force water under the roofline and can damage shared walls. A simple check each season can save you from costly repairs.

If you live in a hot, dry climate, still check your roof and gutters for damage from sun and wind. Keep your shutoff valve location written down so you can stop water quickly if a leak starts.

  • Check roof shingles and flashing
  • Clear gutters and downspouts
  • Trim branches near the roofline
  • Seal gaps around vents and pipes
  • Look for attic water stains

Protect Windows and Doors

Wind-driven rain can push water through window frames and door seals. Inspect caulking around windows and replace any that is cracked or peeling. For older windows, consider adding weatherstripping to block drafts and moisture.

Check exterior doors for gaps at the bottom and sides. A door sweep can stop water from seeping under the threshold. If you have a sliding glass door, make sure the track drains properly.

During a storm, close all windows and doors, and move valuables away from glass.

  • Replace cracked caulk around windows
  • Install weatherstripping on doors
  • Check door sweeps for wear
  • Clear sliding door tracks
  • Move electronics away from windows

Manage Water Flow Around Your Home

Your townhouse shares walls with neighbors, so water that pools near the foundation can affect more than just your unit. Make sure the ground slopes away from the building so rain runs off instead of seeping in.

Extend downspouts at least a few feet from the foundation. If you have a crawlspace, check for standing water and test any drainage system before storm season. Keep the area around your unit clear of debris that could block drainage.

If water enters your crawlspace, dry it within 48 hours to reduce mold risk.

Prepare for High Winds

High winds can tear off siding, damage roof shingles, and send debris through windows. Secure loose items on your patio or balcony, such as furniture, planters, and grills. Wind can turn these into projectiles.

If you have a garage door, reinforce it or install a bracing kit. Garage doors are often the weakest point in a home during a windstorm. Check the track and springs for wear.

For townhouses with flat roofs, inspect the membrane for bubbles or tears. A small tear can let water into the interior.

Create a Storm Response Plan

A storm can hit without much warning. Know where your main water shutoff valve is and how to turn it off. If a pipe bursts, shutting off the water fast can limit damage.

Store important documents in a waterproof container. Keep a list of emergency contacts, including your insurance company and a local water damage pro. If you experience water damage, a professional inspection can identify hidden moisture and help you plan repairs.

Policies vary, and your insurer decides what is covered. Check your policy to understand what storm damage is included.

Frequently asked questions

What should I do right after a storm damages my townhouse?

First, check for safety hazards like downed power lines or gas leaks. If it is safe, document the damage with photos and video. Stop active water leaks if you can, and dry wet areas within 48 hours. Then contact your insurance company and a water damage pro.

Can I prevent all storm damage to my townhouse?

No, storms can be unpredictable, and even well-maintained homes can suffer damage. But you can reduce the risk by keeping your roof and gutters clean, sealing openings, and securing outdoor items. Regular inspections help you catch small issues before they become big problems.

Should I hire a professional to inspect my townhouse before storm season?

A professional water damage inspection can find weak spots you might miss, such as hidden leaks or roof damage. It is a proactive step that can save you money and stress. Inspections are especially useful for older townhouses or after a recent storm.
