Is Your Home Ready for a Wetter Autumn? Five Checks to Make Now
After the UK's warmest summer on record, it might seem a little premature to start thinking about persistent rain, strong winds and winter storms.
But with autumn now under way, it's worth turning your attention to how your home might cope with the months ahead.
There's a particular reason to be prepared this year. According to the Met Office's September 2026 seasonal outlook, the chances of a warmer and wetter-than-average autumn are around one-and-a-half to two times higher than normal. An increased likelihood of windy conditions is also expected later in the season.
The developing El Niño, which is already approaching record strength, is one of the factors influencing the outlook. However, the Met Office stresses that seasonal forecasts cannot predict exactly when or where severe weather will occur.
For homeowners, that makes September a sensible time to carry out a few preventative checks.
At Grove & Dean, our experience supporting home insurance customers means we understand how seemingly minor maintenance issues can contribute to more extensive damage when bad weather arrives.
A blocked gutter, loose roof tile or small leak might not cause immediate problems during dry weather, but several days of heavy rain can quickly expose weaknesses in a property.
Here are five important checks worth making before the wetter weather arrives.
1. Clear your gutters and check your drains
It might sound obvious, but making sure rainwater can drain away properly is an important part of protecting your home.
Leaves, moss and other debris can accumulate in gutters and downpipes, restricting the flow of water.
When heavy rain arrives, blocked gutters may overflow, allowing water to run down external walls or collect in areas where it shouldn't.
Over time, this can contribute to damp and water ingress.
Before autumn gets properly under way, check that your gutters, downpipes and drains are clear and functioning correctly. Clearing gutters and drains as part of regular property maintenance to help prevent damage during adverse weather.
If the gutters are difficult to reach, avoid taking unnecessary risks with ladders. Arrange for a suitably qualified professional to carry out the work.
2. Inspect your roof, particularly flat roofs
Your roof provides one of the most important lines of defence against heavy rain, but minor damage can be difficult to spot from inside the house.
From ground level, look for slipped, cracked or missing tiles, damaged flashing and anything else that appears out of place.
If you can safely access your loft, check for damp patches, torn underfelt or daylight appearing through gaps in the roof.
Flat roofs deserve particular attention and may require maintenance and/or renewal every 10 to 15 years, depending on the materials used.
If you have a flat roof, check its condition and arrange for any areas of concern to be inspected.
A small weakness that causes no obvious problems during a dry summer may become a much more serious issue after several days of persistent rainfall.
If you suspect your roof needs attention, arrange for a suitable roofing professional to assess it rather than attempting potentially dangerous repairs yourself.
3. Look for early warning signs of water ingress
Water damage isn't always immediately obvious.
Sometimes, the first indication of a problem is a small patch of discolouration, peeling paint or an unusual smell.
Before the wetter weather arrives, take a closer look around windows, doors, ceilings and external walls.
Pay particular attention to:
Damp patches or staining.
Peeling or bubbling paint.
Mould or mildew.
Musty smells.
Cracks or gaps around windows and doors.
These can indicate that moisture is entering the property or that another issue, such as condensation or a plumbing leak, needs investigating.
Check for signs of damp around windows and doors and inspect the loft for evidence of damage or water entering the property.
If you notice something unusual, try to identify the source and arrange any necessary repairs.
Discovering a small leak now is preferable to finding water coming through the ceiling during a Sunday evening downpour.
4. Prepare your garden for strong winds
When autumn storms arrive, it's not just the house itself that needs attention.
Garden furniture, bins, plant pots, trampolines and ladders can all be moved or blown over by strong winds.
Before severe weather is forecast, secure or store loose items that could damage your property or neighbouring homes.
It's also worth inspecting fences, gates and sheds for signs of deterioration or instability.
Look at nearby trees, too. Damaged or overhanging branches may present a risk during high winds, particularly if they're close to buildings, vehicles or neighbouring properties.
If branches need attention, arrange for them to be assessed and safely maintained. Where a tree belongs to someone else, contact the owner.
Don't forget to check your insurance. Storm damage to fences, hedges and gates is generally not covered under standard home insurance policies. Cover for garden structures and other outdoor items can also vary.
5. Check where rainwater collects around your property
The next time there's a period of heavy rain, take a look at how water behaves around your home, provided it's safe to do so.
Does water collect beside external walls?
Are your drains clearing properly?
Is rainwater running towards the house rather than away from it?
Pooling water may indicate blocked drainage or another issue that needs investigating.
Pay particular attention to areas near external doors, basement entrances and any lower parts of the property where water could potentially enter.
If your home is in an area susceptible to flooding, it's also worth making sure you know how to access official flood warnings.
Consider which important possessions, documents or electrical items you could move to a safer location if a flood warning were issued.
Preparing in advance means you'll have a clearer idea of what to do if severe weather threatens your property.
Why regular home maintenance matters for your insurance
Home insurance is designed to provide protection against specified insured events, such as certain types of storm, flood or escape-of-water damage.
However, it's important to understand the distinction between sudden, unexpected damage and problems caused by gradual deterioration or normal wear and tear.
Insurance generally isn't intended to pay for routine property upkeep. When assessing storm claims, insurers consider whether the weather directly caused the damage or exposed an existing problem that had developed over time.
For example, a storm damaging a well-maintained roof is different from rain entering through a roof that has been deteriorating for several years.
Whether a particular claim is covered will depend on the cause of the damage and the terms, conditions and exclusions of the individual policy.
This is why regular maintenance is so important.
Keeping gutters clear, maintaining your roof and addressing small leaks can help reduce the likelihood of more extensive damage.
It can also help you understand the condition of your property before severe weather arrives.
The cost of weather-related property damage
The financial consequences of bad weather can be substantial.
According to figures published by the Association of British Insurers in February 2026, insurers paid out £1.2 billion in weather-related property claims during 2025.
Of that total, £758 million related specifically to weather damage to people's homes and possessions.
These figures highlight the impact that storms, flooding and other severe weather events can have on homeowners.
At Grove & Dean, we understand that some weather-related damage is unavoidable. However, identifying and addressing maintenance issues before the worst of the weather arrives can help reduce the risk of preventable problems.
None of the checks we've suggested needs to be particularly complicated.
Spending half an hour looking over your property on a dry September afternoon could help you spot issues that might otherwise go unnoticed until the rain starts falling.
And when it comes to protecting your home, finding a problem early is nearly always preferable to discovering it after the damage has already been done.
