Energy Bill

Will a new roof help lower your energy bill? With the continuous increase in electricity and heating costs, this is a question many people are asking themselves. If you are one of the people thinking about installing a new roof and wondering whether it will improve your home’s energy efficiency, then do continue reading. In this article we will discuss the impact a new roof can have on your energy bill. 

So, will a new roof lower your electricity bill? The short answer is: yes it will. Installing a new roof can help make your home more energy efficient and as a result cut down on your monthly energy costs. Older roofs often have insufficient insulation as well as cracked or missing tiles, which can cause heat loss and lead to higher energy bills. 

How Can Your Roof Affect Energy Costs? 

There are various factors in your home that affect the energy performance of the building.  Draughty doors and windows or improperly insulated basement and loft spaces are only a few of the areas in your house that heat can escape through. When your roof ages, it starts breaking down and becomes less effective in a number of different ways. For one, outside temperature and humidity can seep in and affect the energy efficiency as well as the structure of your home. 

While a new roof will certainly make a difference to your energy bill, however, it’s also important to consider whether the amount you save on your energy bill will be enough to cover the costs of materials and installation in the long run. 

How Will a New Roof Cut Lower Your Energy Bill?

The amount you can save on your energy costs by replacing your roof will depend on different factors including the materials used and how the roof tiles are installed. 

When considering whether a new roof is a smart choice and how it will affect your home’s energy performance, those are some of the important factors to consider: 

  • Ventilation: Roofs are designed to allow ventilation and proper airflow between your loft space and the outside. A properly insulated roof can stop heat from escaping and help you save money on your heating, however, you still need to allow for sufficient ventilation. Without ventilation all the hot air that rises up gets trapped in the loft which can result in condensation and slowly contribute to the deterioration of your roof. In the summer months it can also put a strain on your air conditioning and lead to a noticeable increase in your bill. 
  • Energy Rating: The better the energy rating of your home, the more you can save on your energy bill. Your roof insulation plays a big part in the energy rating of your house. If you have an old house, installing a new roof is a quick way to improve your building’s energy efficiency rating and see great savings on your energy bill. 
  • Type of Roofing Material: The type of roof tiles you choose will greatly impact the energy efficiency of your home and as a result the savings you make on your bill. Certain materials will reflect more or less light than others and also store heat differently depending on their structure. This can all contribute to the overall energy efficiency of your roof. 
  • Solar Reflection: This is an important factor to consider in the warmer month. If your roof can’t reflect sunlight away, all of the heat is absorbed in the roof tiles and transferred into your home. This leads to increased need of running your AC and can result in a higher energy bill. 

How to Choose the Right Roof

Picking the correct roof for your home requires careful planning, particularly if you wish to improve your home’s energy consumption. When doing your research it’s important to consider various aspects such as your home’s location, budget and roofing materials. 

Your Home’s Location

The first important factor to consider is where your home is located. In warm-weather climates you would use a roofing material that allows heat to come out of your home. For this job, it’s better to use light-coloured roof tiles and materials that reflect the sunlight. This will help keep your home cool and reduce your AC bill. In colder climates you want the exact opposite. If you live somewhere with limited sunlight, you want to use darker roof tiles that can absorb all the sun and stop heat from escaping your home. 

What Kind of Tiles Will You Use? 

The other important thing to consider is the type of roofing material you want to use. There are many different types of roofing products to choose from, in different materials, colours and styles. 

Some of the popular options include classic clay tiles, asphalt, reclaimed slates, composite plastic, metal sheets and more. The most energy efficient options out of those are the clay roof tiles, roof slates and concrete tiles. Those materials absorb and retain heat so they are great insulators. In addition they are air-tight and offer great protection against drafts. 

How to Install a New Roof? 

Now you know the benefits of installing a new roof on your home, you might be wondering how to do it? While it is possible to DIY a roof repair, we would recommend getting in touch with a local specialist. There are many safety considerations to take into account when installing a new roof, so it’s always best to leave it to the professionals.
