Will a New Roof Lower Your Electric Bills?

With the cost of living rising and energy prices higher than ever, many people are looking at ways that they can reduce their electric bills. One home improvement you may have been advised to look at is a roof replacement, but will a new roof lower your electric bills? 

Putting a new roof on your house may result in your home retaining more heat, meaning you may need to heat the house less often, which will result in a lower bill. However, there are a number of other factors involved that will determine whether this would be the case for your house.

The state of the current roof

The first major factor that needs to be considered is the condition of your current roof. If you recently had a new roof installed and it is still in good condition, it is unlikely that replacing it will make much difference to your energy bill, unless your current roofing material is a particularly bad fit for the climate where you live. 

However, if your current roof is looking worse for wear due to damaged roofing material or missing tiles, or it has passed its life expectancy, then you may be losing more heat through your roof than is normal. Remember, as much as a quarter of heat generated in the home is lost through the roof and, while this can be reduced, it could also increase if your roof is not in good condition.

The type of new roof

The next factor that will determine whether a new roof will lower your electric bills is the type of roof you are planning on installing. Some roofing materials reflect or absorb heat from the sun better than others. Others, such as clay, are better insulators, meaning they will retain more of the heat inside the house (although the loft or roof insulation is largely responsible for this).

Some roofing materials are also better in certain climates than others. For example, metal roofing (particularly aluminium) is better in coastal climates than some other roofing materials, because it has anti-corrosion and anti-rusting properties that are useful when there is saltwater in the air. This is important because a roof that is inappropriate for the climate will deteriorate quickly, creating a weakness in your roof that will allow heat to escape.

Type of insulation 

Arguably the most important factor as to whether a new roof will lower your electric bill is the type and condition of your insulation. If your current insulation is lacking, then this should be your first consideration before jumping to a roof replacement, provided your roof is in good condition and appropriate for your climate. If you do opt for a roof replacement, you need to ensure that you don’t skimp on the insulation

Your loft or roof insulation is the most important factor in keeping the heat you generate inside your home. There are different options for insulating your roof, depending on whether you have a warm loft (liveable space) or a cold loft (only for storage of items that won’t be damaged by the cold). 

With a combination of the right roofing material and the right insulation, it is possible that a new roof could lower your energy bill. However, this does depend on the state of your current roof and insulation.If you would like to get the condition of your roof assessed, you can speak to our team of roofing experts.
