Roof insulation

Roof insulation

Heat will naturally rise, and as much as 25% of your home’s heat will escape through the loft and roof. This means adequate roof insulation is crucial to reducing your energy bills and cutting carbon dioxide emissions.

Roof insulation will last for 40 years and with payback in as little as two years, it’s an extremely worthwhile investment and cost-effective way to reduce bills.

It doesn’t matter if your roof is uninsulated, or just requires a top-up. You’ll save money either way and help yourself to escape fuel poverty fears.

You’ll be able to install pitched roof insulation, flat roof insulation and even conservatory roof insulation.

How much will I save with roof insulation?

With the rising prices of gas and electricity affecting most homes, finding a way to cut your expenses is very important. Roof insulation is a great way of doing just that, and is installed with minimal hassle and little cost.

270mm is the recommended width of roof insulation, according to the Energy Saving Trust. Whether you have no previous insulation or are simply topping up, this is the desired width.

With the recommended amount of roof insulation, you’ll see annual savings of:

  • Up to £175 off your energy bills

  • Around 720kg off your home’s carbon footprint

With these savings over 40 years, you’ll make a huge saving that’ll benefit both your finances and home’s environmental friendliness.

Insulating pipes and water tanks

It’s not just the roof lagging that will provide insulation and once this is installed, the area above will be noticeably cooler.

This could cause the pipes and water tank to freeze in the winter, if not suitably insulated. This wouldn’t cost too much and you can expect to save a little money on your heating.

It would also be worthwhile insulating the loft hatch with a draught excluder too, to stop cool heat escaping through the cracks.

Roof insulation quotes

Roof insulation is a great way to reduce your bills as most heat loss in your home is through the roof. Lagging helps to retain heat, cutting bills by up to £175 a year.

Roof insulation FAQs

Will roof insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

Which type of insulation is best?

The best type of insulation for your property will depend on the type of walls and any insulation that’s already present. It’s usually a good idea to have some form of wall insulation as well as loft insulation, as this helps to prevent heat loss in both areas.

How long does it take to install roof insulation?

How long it takes to install insulation will depend on the size of your property. In general, loft and cavity wall insulation can be installed in a day or two. External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.
