The roof of a building should do more than keep the rain out. After all, when properly designed and planned, a roof can also be an energy efficiency power house, thus keeping the building occupants comfortable and saving money at the same time.

 

The options for creating an energy efficient roof, or just improving an existing one, are numerous. This means that homeowners will certainly find one or more options that work for them and their budget.

 

Attic insulation

 

Attics are neglected corners of a home that residents rarely visit; unfortunately, this also means that the insulation in an attic is generally insufficient. Homeowners looking to lower energy bills should check that the insulation in their attic has a high enough R-Value for their climate and that there aren't any gaps. For best results, the attic floor and ceiling should be insulated.

 

Install a cool roof

 

Not all roofs are created equal, and there's almost no match for the cool roof's energy efficiency. Made of a variety of materials, there is always one shared characteristic between cool roofs: a highly reflective surface. Most homeowners don't want to start from scratch on their existing roof, so this option is generally only used in new construction. However, there are additional considerations to remember before installing a cool roof: special care is needed to avoid mould and heating bills will be higher in cold months.

 

Roof paint

 

Homeowners generally only worry about the paint on the walls of their home, but a roof needs to be maintained too. Higher quality product will help your energy efficient roof last longer and look better too. When selecting a new paint, remember, lighter colours reflect more heat, which means less need for cooling costs. Not all roofs are suitable for painting. According to Roofline, painting is suitable for several roof types, including concrete tiles and metal surfaces such as Colorbond.

 

Solar panels

 

Solar energy systems are only getting more popular and, as a result, more affordable. However, they aren't a great option for every home. A specialized contractor should be hired to access the home's exposure and potential problems, like trees that will block the sun. Even where challenges are present, there are some workarounds for homeowners who really want to harness the power of the sun.

 

Green roofs

 

While solar panels aren't exactly considered attractive, green roofs most certainly are. Not every building is fit for a green roof as specific architectural requirements must be met. The possibilities for a green roof, however, are essentially endless: vegetable gardens, small trees, flower beds, etc. As an added benefit, the green roof will be removing carbon dioxide from the air while it's being energy efficient.

 

Avoiding asphalt shingles

 

Asphalt shingle roofs, while by far the most popular option in parts of the world, are also one of the least energy efficient. If shingles, for whatever reason, are the only option, then check out shingles that use a highly reflective surface or have solar panel membranes built in.

Unless homeowners are proactive, odds are that their hard earned cash is literally flowing right out their roof. While the most energy efficient roofs are built from scratch, almost all existing roofs can still be improved with some simple changes. However, homeowners who are lucky enough to be building their own house from scratch should really invest in the most energy efficient roof possible.
