Hi everyone, I’m Samm Simon, the friendly face of the Toronto renovation community, and I’m excited to dive into a discussion about the pros and cons of aluminum versus vinyl siding for our homes. As we head into the warmer summer months, I think it’s a great time to explore the benefits and drawbacks of these two popular siding options in a neutral and informative way.
Aluminum vs vinyl siding, without the sales pitch
Aluminum takes heat, holds crisp lines on rooflines and trim, dents but doesn’t crack, and takes paint later if you rebrand the house. Vinyl is cheaper per square, never needs paint, but goes brittle in deep cold and can crack on impact; colour is the colour forever. Roofline trim (soffit/fascia): aluminum, almost always. Large wall fields on a budget: vinyl earns its keep. Mixed systems are normal and smart.
When it comes to durability, aluminum siding is generally more resistant to extreme temperatures and can withstand minor impacts without cracking, but it can dent. Vinyl siding, on the other hand, is more prone to cracking in cold temperatures and fading over time. In terms of maintenance, vinyl siding is often preferred because it never needs to be painted, but the colour you choose is permanent, whereas aluminum siding can be repainted if you want to change the look of your house. The choice between aluminum and vinyl ultimately depends on your budget, personal preferences, and the specific needs of your home.

Good read, Samm. The “friendly face” approach to comparing materials really helps new homeowners.
One thing I’d add from the Mississauga side of things — our freeze-thaw cycles are brutal on both materials, but in different ways. Vinyl contracts and expands significantly more (about 1/8" per 10’ panel between summer and winter). I’ve seen too many installs where the contractor didn’t leave enough gap at the J-channel, and the panels buckled on the first hot day after a cold snap.
Aluminum handles the temperature swing better dimensionally, but here’s the trade-off most people don’t think about: hail. With the storms we’ve been getting in the GTA the last few years, aluminum dents where vinyl bounces back. A heavy hailstorm can leave an aluminum siding job looking like golf ball terrain.
Best advice I can give: whichever you choose, make sure the installer uses slotted nailing flanges (not tightly nailed) and leaves proper clearance at all trim pieces. The material choice matters way less than the installation quality when it comes to long-term performance.
