How to Protect Your Asphalt From Ontario Winters

Ontario winters are the #1 enemy of asphalt

Snow, salt, and the freeze-thaw cycle do more damage to your driveway than years of summer UV combined. Here's how to fight back.

1. Seal before winter

A premium oil-based sealcoat applied in the warm months gives your asphalt a flexible, water-resistant barrier going into winter. This is the single most effective thing you can do.

2. Fill cracks before the first freeze

Water in cracks freezes, expands, and shatters asphalt from the inside. Get hot rubber crack filling done in the fall — ideally before the first hard frost.

3. Watch your salt use

Road salt that gets tracked or shovelled onto your driveway accelerates surface oxidation and weakens the binders. Use sand or a milder calcium-based de-icer where possible.

4. Shovel — don't plow with metal blades

Snow plow blades and snow blower paddles can gouge a sealcoat. Use a plastic-edged shovel where possible, especially in the first few weeks after sealing.

5. Drain water away from edges

Standing water at driveway edges in spring is the start of edge crumbling. Make sure your downspouts and grading direct water *away* from the asphalt.

6. Inspect every spring

After the snow melts, walk your driveway and look for:

• New cracks (mark them for fill)
• Edge crumbling
• Spots where water pools
• Faded or grey areas

Catching damage early is the difference between a $50 patch and a $5,000 replacement.

7. Re-seal every 1–2 years

Even the best sealing job degrades over time. A regular re-seal cycle keeps the protective layer intact and the asphalt below it healthy.

Bottom line

You can't stop Ontario winters — but you can absolutely protect your asphalt from them. Seal, fill cracks, manage salt and water, and inspect every spring. Your driveway will outlast itself.
