When the Roof Insulation is Inadequate Wasted Energy Can Become a Problem
Here in Central Texas we're very conscious about energy costs. Even though the electricity rates are fairly low, the amount of energy consumption that occurs to keep homes comfortable in the summer is notable.
When energy costs seem excessive, something that property owners may not consider is how roofing insulation may be contributing to the problem. In addition to high energy bills, you may notice:
- Significant temperature changes from day to night and vice versa.
- Spots on the ceiling that are colder or warmer.
- Condensation that creates wet spots.
- Ice dams on the roof when the temperature drops below freezing.
- The temperature is inconsistent throughout the house.
When insulation around the roof isn't up to par, your HVAC system is going to get worked overtime. That will do more than waste electricity. It will cause premature wear and tear that shortens the lifespan of your HVAC unit. To avoid all of these problems you'll need to examine the insulation issues and take steps to get the roof better insulated.
Have you noticed your energy bill going up despite using less electricity?

Insulation Issues That Cause Energy Waste at the Roof
Without proper insulation the roof can only do so much to keep a home comfortable in the middle of a hot summer or cold winter. It turns out there can be layers of insulation and other factors that contribute to how well insulated the roof is in any season.
-
Inadequate Attic Insulation
The biggest contributing factor for energy efficiency at the roof is inadequate insulation in the attic. Attic insulation acts as a barrier between the roof and the living areas of a home. It helps to limit the amount of hot and cold air that seeps down from the roof. When there isn't enough attic insulation it's harder to regulate the temperature inside, and you'll feel the difference.
-
Roof Leaks That Damage the Insulation
You may have proper insulation, but a roof leak could be causing it to fail. When moisture is able to get into the attic it can make the insulation wet causing water damage that makes it ineffective.
-
Inadequate Ventilation
You may have installed the right level of insulation, but inadequate roof ventilation could be limiting what it can do. Not only will poor ventilation cause warm and cool air to linger, it can also create condensation that damages attic and roof insulation.
-
Lack of UV Protection From the Sun
The exterior of the roof is another type of insulator for a home or building. Some roofing materials are better at deflecting solar heat so that it doesn't transfer into the structure. There are also special coatings that can help reflect the UV rays. If you use the wrong roofing materials they may not provide enough insulating protection from the sun.

How to Keep Energy Costs in Check With Proper Roof Insulation
Whether inadequate roof insulation is the result of a poor installation or water damage, the result is the same - wasted energy that costs you money. Here are some ways that you can correct the situation to stop wasting electricity and start feeling more comfortable.
Get a Roof Inspection to Assess the Situation
Regular inspections provide homeowners with a lot of valuable information. A professional roofer can not only tell you if you have proper insulation but also identify other ways you can save energy with roofing improvements. For example, the roofer may find that you have a lot of air leaks around the roof or there isn't enough ventilation to circulate the air.
A roof inspection will give you a full rundown of all the ways you can stop wasting energy and start saving money.
Add More Attic Insulation
If the attic insulation is inadequate there's only one fix - add more insulation. Here again it helps to work with an experienced roofer. They can tell you what level of insulation is most appropriate for the local environment, and more importantly, your home.
Apply a Protective Coating to the Roof
You can make your roof more energy efficient with a special protective coating that blocks UV rays so that the roof absorbs less solar heat. It's like a first layer of insulation that helps to keep the temperature inside more comfortable and constant from the outside.
Some roofing materials are made with protective coatings already applied. You can also apply protective coatings to existing roofs in some cases. Just be careful if you have asphalt shingles because adding a protective coating could void the warranty.
Consider Adding Roof Insulation
Roof insulation is added to the areas between the roof deck and ceilings rather than on the floor of the attic. Insulation that can be applied directly to the roof deck includes blown-in cellulose, perlite cover boards and spray foam insulation.
Make Sure the Roof is Properly Maintained
Last but not least is regular inspections and roof maintenance. It will not only keep the roofing material in better condition so it insulates better but will help you catch issues like leaks that can make insulation less effective.
