As you are preparing your household for winter, you may have taken certain steps, such as having your heating system looked at by an HVAC professional. One thing that you might not have done yet, however, is to have insulation put into your attic. However, it's a good idea to fill your attic with insulation before the extreme cold weather hits, and spray foam insulation is a particularly good choice. These are a few reasons why.

Keep Out Critters

As the weather gets colder, various critters will be looking for a warm, safe place to nest for the winter. Although you might feel for the squirrels, birds, mice and other critters, you don't want them nesting in your attic. If they are able to get in through a crack or crevice around your roof -- and you shouldn't be surprised if these crafty creatures can -- then they can cause serious damage to your attic and can infest your home. Filling the top of your attic with spray foam insulation will help ensure that it is filled to the brim, which means that there won't be cozy fiberglass insulation that can be moved out of the way and used to create a nest. Instead, the spray foam insulation will help keep the critters out completely.

Prevent Ice Dams on Your Roof

During the winter months, you have to worry about ice dams forming on your roof. Once ice freezes on top of your roof, it can be difficult to remove and can cause a lot of heavy weight on top of your roof, which can result in major roofing damage.

If your attic is properly insulated, however, it can keep your roof a bit warmer and will help prevent this from happening. Since spray foam insulation can be installed more tightly in your attic, it can provide more warmth and insulation than other types of insulation.

Keep Your Attic Air-Tight

You're probably already expecting your heating bills to rise as the temperatures get colder, and you probably want to prevent that from happening as much as possible. Putting in spray foam insulation will help you ensure that your attic is as tightly-insulated as possible, which will help protect your house from the cold and will help prevent your heating bills from rising any more than necessary.

As you can see, adding spray foam insulation to your attic before the winter is a smart move. When you do so, you'll be able to enjoy these perks and more. Contact a company like Energy Home Insulation Inc to learn more.
