Why are icicles forming on my soffit
Posted On: February 2, 2022
The soffit is the material on your home beneath the eaves trough that connects the roof's edge to the exterior wall. You can also find them on the underside of your porch. Suffit's are essential for protecting eaves and rafters from moisture. There are two types of soffits, vented and solid.
Ventilation is essential in maintaining the lifespan of your attic. Proper ventilation keeps your house cool in the summer by moving the hot air out. And in the wintertime, the cold air moving to the attic is a good thing as it prevents the snow from melting and refreezing too quickly, extending the life of your roof.
The average asphalt shingles in Ontario can last anywhere between 15 to 30 years. But without proper ventilation and quick thaws and freezes, that time can be decreased.
One of the biggest reasons for icicles on your soffit is the attic. If the insulation in your attic is old, the heat will escape through the roof. Any snow on the roof will rapidly melt and freeze, causing icicles to form. You should also relocate any machines that give off heat from your attic to somewhere else in the home.
Another way to prevent icicles from forming is to clean your gutters before it gets too cold. That way, when there is a deep thaw, the melted snow will have somewhere to go. And no ice can build up when the temperature drops again. Not only is cleaning the gutters essential for maintaining your roof, but it's also good for prolonging the life of your eaves.
Poor ventilation can cause icicles, clear all vents from snow and other debris to allow warm air to escape. If your roof doesn't slope and snow has built up, you should also shovel off any snow to prevent water damage from melting snow and ice.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
