Keep the Heat In: How Much Warmth is Lost Through a Poorly Constructed Roof?

Did you know that the roof of your house could be one of the biggest sources of energy loss in your home? If your roof is not properly constructed or maintained, a large amount of heat can escape through it. This can mean higher energy bills and uncomfortable living spaces. So, let’s take a look at how much warmth escapes from the roof if it is not properly constructed or maintained. 

What Causes Heat Loss? 

Heat loss occurs when there are gaps and cracks in the roof, as well as when insulation is inadequate. A poorly sealed roof will allow air to enter and exit, which means that warm air escapes during winter months and cool air escapes during summer months. The more air escaping, the greater the amount of heat lost from your home. Insulation also plays an important role in preventing heat loss; if insulation is absent or inadequate, it won’t do its job of trapping heat and keeping your home warm.  

How Much Heat Is Lost? 

The amount of heat lost from a poorly constructed or maintained roof depends on several factors, including the size and type of house, the climate you live in, and the efficiency of your heating system. Experts estimate that up to 25% of heat can escape through a poorly insulated attic—that’s more than enough to make a noticeable difference in your energy bills!

Proper Construction Matters 

The materials used in your roof construction play a vital role in how much heat escapes from your home. Heat rises, so if your roof isn’t built with proper insulation, then you’ll be losing a lot of warmth every time the weather turns cold. You also need to ensure that there are no gaps between the roof and the walls of your home as well as between each part of the roof structure (for example, around chimneys). Sealing these voids will help reduce heat loss significantly.

Regular Maintenance Is Key 

Even if your roof was properly constructed, regular maintenance is still key when it comes to preventing heat loss. Over time, cracks can form in shingles or tiles due to normal wear and tear or severe weather conditions such as hailstorms or heavy winds. These cracks may seem small, but they can allow up to 40% more heat to escape from your home in cold weather! If this happens, you may want to consider replacing those damaged shingles or tiles with better-insulated materials.  

You should also check for any signs of water damage such as discolouration or moss growth on the underside of your roof. Water damage often leads to rotting which means that warm air will start leaking through those holes instead of staying inside where it belongs. In addition, keeping trees trimmed away from your house helps reduce any chance for pests and birds who might decide to make their homes on top of yours!        

What Can You Do to Improve Your Roof’s Insulation? 

There are several steps you can take to improve the insulation of your roof and reduce heat loss in your home: 

• Check for any existing damage or wear-and-tear on your roof. If there are any holes or lose shingles, patch them up as soon as possible. 

• Make sure there is adequate insulation in your attic and replace any old material with new insulation if necessary. 

• Have a professional EPC assessor evaluate the condition of your roof every few years – they may be able to spot any potential issues before they become major problems.

• Consider investing in solar panels – not only are they good for the environment but they can help keep your home cool during hot summer days (and warm during cold winter nights).  


Heat loss through a poorly constructed or maintained roof can have serious consequences for both comfort levels in your home and energy costs throughout the year. Fortunately, there are easy steps you can take to prevent this from happening—such as inspecting for drafts and replacing old insulation—that can help safeguard against costly energy bills due to excessive warmth escaping from your home’s roof! Taking these steps now could save you money over time–so don’t delay! Get started on protecting against heat loss today!
