Keeping Lofts Cool In The Summer

Keeping your loft cool in the summer

When it comes to temperature control for house extensions, much of the focus is often on ways in which to retain heat. Here we focus on the best ways of keeping lofts cool in the summer.

In the UK, an exposed roof can cause a chilly loft however, during the summer, this concept is turned on its head and lofts can become almost like a greenhouse, trapping heat and creating a stuffy atmosphere.

It’s a scientific fact that heat rises. Couple that with the exposure to sunlight hitting your roof and, assuming it is properly insulated, your loft could be the hottest room in the house come Summer.

Here are a few tips to help you to combat the heat in your attic this summer:


Fundamentally, if there is no way for heat to escape, temperatures will quickly rise. Ventilation doesn’t necessarily mean air conditioning (although this would solve the problem!) – simply having a Velux roof window installed on one sloping wall and a vent towards the bottom of the facing wall to pull cooler air up from below and let it escape out of the elevated window.


It may sound counterintuitive to insulate a room that you are trying to cool down, ensuring that your roof space is properly insulated can go a long way towards keeping it cool in the summer. Just as insulation keeps heat in, so to can it deflect it away (especially if radiant barriers are used), saving you money on air conditioning and fan use just as it does on heating during the winter.


While dormer or Velux windows are essential for effective ventilation and increased airflow, if the sun is shining through them all day onto your carpets and soft furnishings then the temperatures will rise steadily and you will return home to a stuffy loft room. Fit all attic windows with retractable blinds or shades, and keep these closed while you’re out during the daytime.

Overhanging, deciduous trees on either the western or eastern side of your home will help to shade rooms within the house, although large shrubs planted on the southern side might obstruct low winter sun which is needed for heat during these months.

Roof Colour

If possible, changing the colour of your roof from dark browns and greys to lighter shades can help to reflect the sun’s rays, reducing the greenhouse effect on your loft. Terracotta can provide a nice option here, so long as the material is suited to your environment.

Remember, painting or weatherproofing your roof is a highly dangerous activity, and should be performed by a professional if you are in the least bit unsure as to what you’re doing.
