Stay Warm and Save Money This Winter Through Proper Roof Insulation

Stay Warm and Save Money This Winter Through Proper Roof Insulation

Winter is coming, which for most means a climb in heating bills. Fortunately, there are ways to stay warm without spending a small fortune. Home insulation is the key to lower winter energy costs, keeping heated air in the house and cold air out. One of the major areas where you want to limit heat transfer is your roof. Here's how to insulate the roof so your family stays warm and cozy while your energy bills stay under control.


The first step is simple and inexpensive and involves working with what you have. Keep your roof in good shape via regular inspection and prompt repair. Fix loose, curling, or cracked roofing shingles and take care of any rotted wood or gaps in the roof fascia, soffit, and flashing immediately. This kind of preventive medicine will safeguard the inside of your home against icy drafts as well as water leaks.

"Cold" vs "Warm" Roof Space

Next, you'll need to decide between a "cold" and a "warm" roof space. These terms refer to exactly where the roofing insulation will be installed, not to the resulting temperature in your living space. In fact, a cold roof space is advisable if you live in a part of the country that has severe winters. It is much less likely than a hot roof to cause fallen snow to melt and refreeze, forming hazardous ice dams. It's also simpler and less expensive to retrofit with insulation. A warm roof, however, does allow a higher level of heat retention.

Blanket Insulation

Blanket insulation is one of the most common methods of insulating a cold roof space, and is traditionally manufactured from fiberglass. Your roofing contractor will install a vapor barrier as needed. They will then carefully roll out the blanket insulation on top of the barrier, ensuring that it is flush with the roof joists and eliminating any gaps between lengths of insulation. Have your contractor cut an opening in the blanket for the electrical components to prevent their overheating.

Spray Foam Insulation

Spray foam may be used to insulate both hot and cold roofs. Have your roofing professional double check that your roof is in good shape before attempting this type of treatment and make sure to coat all rafters or trusses thoroughly with the foam, to prevent heat transfer via the wood.
