Roof Colour and Material: How Does it Affect Your Indoor Temperature?

01 December 2022

The majority of homeowners are aware that a variety of factors, including weather, a home’s roofing type, the state of its windows, air conditioning units, and heating systems, can affect the temperature inside their home. Did you know that in addition to these factors, one more contributes to keeping a suitable temperature without costing extra? It’s the colour of your roof. Johnson Roofing, a reputable roofer, explains how it works in this post.

The Colour of Your Roof

Numerous factors, including the colour of your roof, can influence how warm or cool your home is inside. Dark colours tend to absorb heat and sunshine, contrary to the widely held belief that light colours tend to reflect sunlight and reject the heat it transmits. With some exceptions, the same holds true for your roofing. Light-coloured roofs typically assist in maintaining cooler indoor temperatures by deflecting the sun’s heat waves. On the other hand, dark-coloured roofs absorb the sun’s heat waves and radiate this heat upward, increasing the temperature of the spaces inside.

You should also take into account the following before deciding that light-coloured roofs are always preferable.

The Type of Roofing Material

Different types of roofing materials react differently to sunlight. For instance, metal roofing reflects the heat of the sun better than asphalt shingles. As a result, choosing a dark-coloured metal roof over a light-coloured shingle roof may not necessarily be a terrible idea.

The Weather Conditions

The performance of your roof also changes with the time of year and varied weather conditions.  Light-coloured roofs, for instance, will assist in lowering cooling costs by blocking the heat from the sun from entering your home during the summer. Contrarily, light-coloured roofs are less effective than darker roofs at retaining heat, resulting in higher heating costs during the winter. Dark-coloured roofs don’t help homes cool off during the summer, but because they are good at absorbing heat, they reduce heating bills during the chilly winter.

It All Comes Down to Your Decision

You now realise that there is no simple way to state that roofs with lighter colours are always preferable to those with darker ones. Both of them offer advantages and disadvantages, so you can ultimately choose whichever one you want. At the end of the day, it will still come down to your decision.
