Your home works hard through a Southern Ontario winter. Snow, ice, freezing temperatures, heavy rain and repeated freeze-thaw cycles can put significant stress on your roof, foundation and drainage systems.
The good news? A little preventative maintenance in the spring and fall can help identify small problems before they turn into expensive repairs.
Whether you're a longtime homeowner, preparing to sell, or simply want to protect your investment, these seasonal checks should be on your radar.
Spring: Check for Winter Damage
Spring is the perfect time to walk around your property and look for signs of damage caused by snow, ice and freezing temperatures.
1. Clean Your Eavestroughs & Downspouts
Winter debris, leaves and shingle granules can accumulate in your eavestroughs. When they become clogged, melting snow and spring rain may overflow directly beside your foundation.
Check that:
- Eavestroughs are free of leaves and debris.
- Downspouts are clear and securely attached.
- Water flows freely through the system.
- Downspouts direct water away from the foundation.
- There are no leaking seams or sections pulling away from the house.
- CMHC specifically recommends cleaning eavestroughs and downspouts in both spring and fall and ensuring water is directed away from the foundation.
2. Inspect Your Foundation
Once the snow has disappeared, walk around your home and look closely at the foundation.
Watch for:
- New cracks
- Cracks that appear to be getting wider
- Damp or stained areas
- Efflorescence (white, powdery deposits)
- Standing water near the foundation
- Soil that has settled away from the house
Southern Ontario's freeze-thaw cycles can expose weaknesses that weren't obvious before winter.
Don't ignore water. If you notice recurring water intrusion, significant cracking, bowing walls or movement, consider having the issue assessed by an appropriate professional.
3. Check Your Grading
Take a look at the soil immediately surrounding your home.
Ideally, water should flow away from the house, rather than pooling alongside the foundation.
Spring is an especially good time to look for areas where soil has settled over the winter. The Government of Canada recommends checking property grading in both spring and fall and watching for erosion, low spots and areas where water flows toward the home.
4. Inspect the Roof From the Ground
You don't necessarily need to climb onto your roof to spot potential problems.
From ground level, look for:
- Missing or damaged shingles
- Curling or cracked shingles
- Loose flashing
- Damaged vents
- Sagging areas
- Excessive moss or debris
- Signs of damage around chimneys and skylights
If something looks questionable, have a qualified roofing professional inspect it rather than attempting a dangerous DIY roof inspection.
5. Don't Forget the Attic
Some roof problems are easier to identify from inside the house.
Look for:
- Water stains
- Damp insulation
- Mould or unusual moisture
- Daylight coming through areas where it shouldn't
- Signs of previous leaks
Catching a small roof leak early can prevent damage to insulation, drywall, ceilings and structural components.
Fall: Prepare Your Home Before Winter Arrives
Fall is your opportunity to get ahead of winter rather than discovering problems after the first major snowfall.
1. Clean Your Eavestroughs Again
This may be the single most important fall exterior maintenance task.
Leaves can quickly fill eavestroughs, especially if your property has mature trees.
Before temperatures drop:
- Remove leaves and debris.
- Check downspouts for blockages.
- Make sure water can flow freely.
- Ensure extensions direct water away from the foundation.
- Check for sagging or loose sections.
The goal is simple: rain and melting snow need a clear path away from your home.
2. Inspect the Roof Before the Snow Arrives
Fall is an excellent time to address roof issues before they're hidden beneath snow and ice.
Have damaged shingles, flashing or other roof problems repaired before winter whenever possible.
Ontario's maintenance standards emphasize that roofs should remain watertight and that roof drainage components—including gutters and rainwater leaders—need to be maintained and kept clear of obstructions.
3. Check Your Foundation Drainage
Walk the perimeter of your home after a significant rainfall.
Ask yourself:
Where is the water going?
If you see water pooling beside the foundation, it's worth investigating before winter.
Check:
- Downspout discharge points
- Soil grading
- Low spots
- Window wells
- Drainage swales
- Areas where landscaping has settled
Water sitting against your foundation in the fall can become a much bigger problem when temperatures begin fluctuating.
4. Check Window Wells
If your home has basement windows below grade, make sure the window wells are clear of leaves and debris.
Remove anything that could prevent water from draining properly, and check that the wells aren't damaged or excessively full of soil.
5. Trim Problematic Branches
Take a look at trees near your roof and house.
Dead or damaged branches can become a problem during heavy snow, ice storms and high winds.
Removing potentially hazardous branches before winter can help protect:
- Your roof
- Siding
- Windows
- Vehicles
- Landscaping
For larger or potentially hazardous trees, consider hiring a qualified arborist.
The 15-Minute Exterior Walk-around
One of my favourite homeowner habits is a simple seasonal walk-around.
Twice a year, walk around your entire property and look at your home as if you were seeing it for the first time.
Look up at the roof.
Look down at the foundation.
Follow the path of water from the roof → eavestrough → downspout → ground.
Then ask:
"Is the water going where I want it to go?"
That one question can help you identify a surprising number of potential problems.
Signs You Shouldn't Ignore
Some maintenance issues deserve more than a quick DIY fix.
Consider getting professional advice if you notice:
- New or rapidly growing foundation cracks
- Water entering your basement
- Bowing or visibly shifting foundation walls
- Persistent water pooling beside the house
- Significant roof leaks
- Sagging roof areas
- Extensive shingle damage
- Repeated ice damming
- Wet or mouldy attic insulation
- Structural movement around windows or doors
The earlier a problem is identified, the more options you may have for addressing it.
Why This Matters When You're Selling Your Home
Seasonal maintenance isn't just about avoiding repairs today. It's also about protecting your home's value.
When buyers purchase a home, they are looking closely at the roof, basement, foundation, drainage and overall condition of the property.
A well-maintained home can provide buyers with confidence – and potentially prevent a small maintenance issue from becoming a negotiation point during the sale.
If you're thinking about selling in the next year or two, spring and fall maintenance are also great opportunities to create a running list of repairs and improvements rather than trying to tackle everything immediately before listing.

Protect Your Home Before You Need to Repair It
Southern Ontario homeowners can't control the weather—but we can control how prepared our homes are for it.
A couple of seasonal inspections can help catch drainage, roof and foundation issues before they become much larger problems.
And if you're considering buying or selling a home in the Guelph and surrounding area, having someone who understands both the market and the practical realities of home ownership can make a big difference.
Thinking about your home's value, preparing for a future sale, or wondering which improvements are actually worth doing? Let's talk.
