Prevent Ice Dams With Attic Insulation

As winter approaches, savvy homeowners start to consider the many tasks required to keep their houses warm and dry. This involves many jobs, from shutting off external pipes to gutter cleaning. One of the reasons we do this is to prevent ice dams, a process where water builds up and freezes on your roof. But did you know that insulating your attic is one of the best ways to get your house ready for winter? It’s quite obvious if you think about it!

At Tropical Insulation, we have the product knowledge and installation expertise to help you choose and install the best insulation for your home. Keep reading to find out why we’re Southern Ontario’s best insulation installation!

Prevent Ice Dams With Attic Insulation

As a homeowner, you have many critical tasks to winterize your home. Some are easier, like shutting off a water valve, and others require forward thinking and investment. But in the long term, insulating prevents ice dams and saves you monthly on your energy bill.

Let’s get into the fine details. How does insulating your attic stop frozen clogged drains and icicle formation?

What Causes Ice Damming?

When the snow begins to fall and gathers on your roof, this is actually a good thing for maintaining constant heat. Snow acts as an insulator, further protecting spaces like attics from heat loss. The problem, however, comes when the snow melts due to air gaps in your insulation and roofing.


As the snow melts, it runs through the lowest point on a roof, usually a gutter or an eave. Once this process builds up, it clogs proper drainage and causes large icicles to form. Ice dams can even cause structural issues! Not only can this be dangerous, but if left alone long enough, it requires professional maintenance to handle. If this occurs regularly enough, then it can be quite costly.

That’s why attic insulation is the most effective solution for preventing ice dams. By protecting your roof from heat loss, you’ll transform the snow from a massive problem into a useful natural insulator.

How to Prevent Ice Dams

So how does attic insulation protect your home from ice dams exactly? Well, by creating a vapour barrier, otherwise known as an air seal, you trap the warm air in your home. An air-tight seal and a physical barrier is the essential solution here. This barrier between the cold air outside and the warm air inside stops the snow from melting on your roof (unless you get a warm day).


Preventing ice dams is just one of the benefits of insulating your attic. Keep reading to find out why we recommend homeowners across Ontario insulate their attics before winter comes.

Attic Insulation Benefits

Just like how you don’t go outside without a toque in cold weather, your house is much the same. Heat escapes our heads in the same way it does our homes. Your attic is where the most heat loss occurs! So let’s break down the benefits of insulating your attic.

  • Prevents ice damming
  • Saves money on your energy bill
  • Improves indoor air quality
  • Structural protection
  • Protects from pests

With all these benefits in mind, insulating your attic is an obvious choice! With Tropical Insulation, we advocate for and specialize in the use of cellulose. Keep reading to find out why!

Why We Use Cellulose

Cellulose is a sustainable insulation material that is made from natural fibres.  Historically, one form of it or another has been humanity’s choice of insulation more than any other material. Nowadays, cellulose is primarily made from recycled paper and denim. Cellulose is specifically engineered to have superior thermal performance across many environments. It’s heavily treated to be an effective flame retardant, and prevent pests. But why do we specialize in it?


Cellulose has many benefits. It’s fantastic at insulating against sound. It’s safe to install and safe to live in, so there’s no itchy skin or irritated lungs. And best yet, we believe that sustainability is the future of Canadian business. That’s why we only use the highest quality and ethically sourced cellulose. We know it’s best for the environment and best for our future.
