To make sure that your home is well insulated, you need attic insulation that will keep your home at your desired temperature no matter the weather conditions. Properly installed attic insulation will also save you money on heating and cooling your home. It’s estimated that up to 40 percent of a home’s heat loss occurs through the attic, which underscores the importance of ensuring that your attic insulation is up to code. As of 2017, the new standard for attic insulation is at an R60 rating and equates to between 17 and 22.5 inches of insulation.

By installing new attic insulation in your home, you can improve your home’s energy efficiency, providing savings for years to come. At Davidoff Roofing, we provide superior attic insulation services to homeowners in London, Ontario, and surrounding areas as a part of our home exterior renovation services.

How to Tell If Your Home Needs Improved Insulation

There are many ways to tell if your home requires improved attic insulation. Perhaps the best indicator is the age of your home. Many older homes have less than 6 inches of insulation in the attic, which is far below today’s standard. Other signs to watch for that could indicate a need for improved attic insulation include: 

  • High heating and cooling costs 
  • An overworked HVAC system
  • Cold/warm spots in the home 
  • Ice buildup on the roof in winter

Types of Insulation for Your Attic Roof

Insulation comes in many types, such as loose-fill, rolls, and foam board, but the best insulation for attics is spray foam. Not only does it provide a high R-rating, but it can get into many of the nooks and crannies in the attic that other types of insulation cannot. Blow-in insulation is also a viable option for the attic, with materials able to fit into tight spaces. We use industry-leading Owens Corning insulation on many of our attic insulation jobs.

Frequently Asked Questions Regarding Insulating Your Attic

Insulating the floor is standard practice, however it can make sense to insulate the underside of the roof as well. At Davidoff, our consultation includes determining where insulation will work best in your property.

Yes! Too much insulation and your home will be unable to “breathe.” This can lead to moisture being trapped and mold growth. Insulation is important, but so too is proper ventilation. Too much insulation can hinder that.

This largely depends on the type and quality of the old insulation. For instance, if it’s wet or showing signs of a pest or rodent infestation, then it should be removed before new insulation is installed. However, in many cases, new insulation can be installed over the existing insulation.

The amount of insulation used depends on the type of insulation used, the R-value you want, and the size of your attic space.

While the average lifespan is between 20 to 30 years, degeneration can start as early as 15 years after being installed. Severe weather and the type of insulation may reduce the lifespan.
