Ice Dams: What They Are & How to Prevent Costly Roof Damage
Winter can be tough on homes, and with the recent milder weather, ice dams are becoming a real threat for homeowners. If left unchecked, these icy buildups can lead to costly repairs and serious water damage inside your home. But don’t worry—we’re here to help you understand what ice dams are, how they form, and most importantly, how to prevent or get rid of them.
What Is an Ice Dam?
An ice dam is a ridge of ice that forms at the edge of your roof. It happens when snow melts during the day due to heat escaping from your home and then refreezes at night when temperatures drop. Over time, this ice barrier traps more melting snow behind it, preventing proper drainage. The result? Water backing up under your shingles, leaking into your home, and causing potential damage like:
- Roof leaks
- Insulation damage
- Mold growth
- Stained ceilings and walls
How to Prevent Ice Dams
Prevention is always the best solution when it comes to ice dams. Here are some key steps you can take to protect your home:
- Ensure Proper Insulation & Ventilation – A well-insulated attic helps keep warm air from escaping, reducing the chances of snow melting on your roof. Good ventilation also helps regulate temperature and prevent ice buildup.
- Clear Snow From Your Roof – Using a roof rake, carefully remove excess snow from your roof before it has a chance to melt and refreeze.
- Seal Air Leaks – Check for gaps in your attic, around light fixtures, and near chimneys where heat may be escaping. Sealing these areas can reduce uneven roof temperatures.
- Clean Your Gutters – Make sure your gutters and downspouts are free of debris to allow melted snow to drain properly.
How to Get Rid of an Ice Dam
If you already have an ice dam forming, here are a few ways to safely remove it:
- Use a Roof Rake – Gently pull snow off your roof from the ground. Avoid using sharp tools that could damage your shingles.
- Create Drainage Channels – You can melt sections of the ice dam by applying calcium chloride (NOT rock salt, which can damage your roof). Fill a nylon stocking with the de-icer and lay it across the ice dam to help create drainage paths.
- Call a Professional – If ice dams are severe or water has started leaking into your home, it's best to call in a professional roofing or ice removal service.

Cooler Temperatures, Warmer Opportunities The fall market in Milton is revealing a trend we’ve been watching closely: more choices for buyers and steady pricing across property types . October 2025 showed a notable increase in sales activity month-over-month, even as average prices ticked down slightly. Sales Rebound as Buyers Re-Enter the Market Home sales in Milton climbed to 169 transactions in October—up a significant 28.03% from September. While the average sale price dipped slightly by 0.94% to $1,026,445 , the increase in activity suggests buyers are regaining confidence amid stabilizing mortgage rates and more realistic pricing. TRREB President Elechia Barry-Sproule recently commented on similar market trends GTA-wide, saying: “Buyers who are confident in their employment situation and ability to make their mortgage payments over the long term are benefitting from affordable housing market conditions relative to the past few years.” That certainly seems to apply in Milton, where more buyers are seizing the opportunity to get into the market—or move up. New Listings Down, But Inventory Still Healthy October saw 349 new listings in Milton, a 19.03% decline from the previous month. However, this decrease came after a surge of inventory in September. Despite the drop, the sales-to-new-listings ratio rose to 48% , up from 31%, signalling a more balanced market with stronger buyer demand. Detached homes remain the most active category, with 79 sales in October, followed by townhomes (43 sales) and semi-detached homes (20 sales) .

Interest Rate Cuts Spark Buyer Optimism September brought a renewed sense of confidence to Milton homebuyers as the Bank of Canada’s recent interest rate cut created more favourable borrowing conditions. This shift made monthly mortgage payments slightly more manageable, encouraging renewed activity—though Milton’s market is still clearly favouring buyers. “The Bank of Canada’s September interest rate cut was welcome news for homebuyers,” said TRREB President Elechia Barry-Sproule. “With lower borrowing costs, more households are now able to afford monthly mortgage payments on a home that meets their needs.” Sales Hold Steady, Inventory Climbs In September 2025, Milton recorded 132 home sales, holding steady with August. However, new inventory surged 16 percent month-over-month, reaching 431 listings. This increase in supply, paired with consistent sales, resulted in a Sales-to-New-Listings Ratio of 0.31 — down from 0.36 in August. This ratio firmly positions Milton in buyer’s market territory. Compared to September 2024, sales were up nearly 4 percent, while new listings jumped by 14.6 percent, giving homebuyers more options to explore. Prices Rebound Month-over-Month Milton's average sale price climbed to $1,036,162 in September — up a strong 7.5 percent from August 2025, and modestly up 1.4 percent year-over-year. Median prices tell a similar story, rising to $955,000, a 4.7 percent monthly increase. These gains suggest that while buyers are cautious, well-priced and desirable homes are still commanding strong offers. However, it’s important to note that price growth was segment-dependent, with detached homes and townhouses seeing more buyer traction than others.
