The rainy season isn’t just an inconvenience—it’s a major test for your rental property. Leaks, drainage issues, mold growth, and water damage can lead to costly repairs and frustrated tenants if left unaddressed. That’s why property owners and managers need to prepare long before the first storm rolls in.
Whether you’re managing a single-family home or a small portfolio of rentals, taking a proactive approach to wet weather can save you thousands in repairs and reduce tenant complaints. Here’s how to make sure your rental is rain-ready.
Start With a Roof Inspection
Your roof is your property’s first line of defense against rain. Even a small crack or missing shingle can lead to leaks that damage ceilings, walls, and insulation.
Before the rainy season:
- Check for loose, curling, or missing shingles
- Inspect flashing and sealant around vents and chimneys
- Clear debris like moss, branches, and leaves
- Consider hiring a pro if you’re unsure—roofs are too important to guess on
Many local managers recommend scheduling annual or bi-annual roof inspections. It’s a small cost compared to what you’d pay for water damage remediation.
Clear Gutters and Downspouts
Clogged gutters are one of the most common causes of rain-related issues. When water can’t flow freely, it backs up under shingles or overflows around the foundation.
Make sure to:
- Remove leaves, nests, and debris from all gutters
- Check that downspouts direct water away from the building
- Add extenders if needed to carry water at least 3–6 feet away from the foundation
If your property is surrounded by trees, you may need to clean gutters more than once per season.
Inspect the Foundation and Drainage
Heavy rains can expose problems with your property’s grading and drainage. Puddles forming near the home? Water trickling into the basement? Those are signs that the ground may be sloped incorrectly.
What to check:
- Soil should slope away from the building by at least 6 inches over the first 10 feet
- Look for signs of erosion or standing water
- Install French drains or swales if necessary to divert water
If a tenant reports musty smells or dampness near the foundation, address it immediately—it’s easier to fix before the full rainy season sets in.
Seal Doors and Windows
Water intrusion doesn’t always come from above. Gaps in door frames, window sills, and siding can let in moisture that leads to rot, warping, or mold.
Preventative steps:
- Re-caulk window and door trim as needed
- Replace cracked or old weather stripping
- Check that storm windows close properly
This also helps with energy efficiency—keeping heat in and drafts out during cold, wet months.
Test Sump Pumps and Backflow Valves
If your property has a basement or crawlspace, sump pumps are a must-have. But they only help if they’re working when you need them.
Do this before the storms hit:
- Test the sump pump by pouring water into the basin to make sure it turns on
- Ensure the discharge pipe routes water away from the home
- Install or check backflow valves on basement drains to prevent sewage backups
A failed sump pump during a storm can lead to thousands of dollars in water damage—not to mention the tenant headache.
Review Landscaping and Tree Health
Overgrown trees and poorly placed shrubs can create problems during heavy rain. Roots may clog drain lines, branches could fall on the roof, or dense landscaping could trap moisture.
What to look for:
- Trim back overhanging branches to reduce roof impact
- Remove dead or diseased trees before they fall in high winds
- Keep vegetation from growing too close to siding or vents
A few hours of landscaping cleanup now can save you from emergency calls during the stormiest weeks.
Talk to Your Tenants
Tenants are your eyes and ears on the ground. Keeping them informed about what to watch for—and encouraging them to report issues early—can prevent small problems from escalating.
You can:
- Send out a seasonal checklist (e.g., what to do if a leak is spotted)
- Let them know how to reach you or your property manager quickly
- Remind them to keep windows closed during storms and avoid blocking vents
Establishing this kind of communication helps tenants feel taken care of—and helps you get ahead of maintenance.
Don’t Forget the Small Stuff
Some rainy season prep items are easy to overlook but can make a big difference:
- Test exterior lighting for dark, stormy days
- Secure loose siding or fence panels before high winds hit
- Stock up on sandbags if your area is flood-prone
- Check attic insulation and ventilation to prevent condensation buildup
Each small fix adds up to a more protected, resilient property.
