3 Myths About Flat Roofing
Daniel Bracewell • 16 August 2021
If you’re planning to build a modern home or an extension on your home, you might have some misgivings about flat roofs. Despite flat roofs have been around for centuries, they are surrounded by many myths that can make them look like an impractical choice.
However, whether you want to create a green roof, use the space for solar panels, or create a terrace, it’s important to know the truth about flat roofs, so we have a brief guide to bust three myths about flat roofs.
1. They leak
Flat roofs are not completely flat, and they are designed to shed water effectively with a slight pitch. Combined with adequate gutter and drainage systems, flat roofs are no more likely to leak than any other kind of roof. Waterproof membranes can be applied to flat roof construction, and offer an extra barrier against the elements that will last for 10 to 15 years.
2. They’re expensive
Flat roofs require fewer materials, and the simple design means they can be installed faster and with less labour than other roofs, making them a less expensive option. The choice of materials will also determine the costs, so ensure you get estimates for different types of materials and designs.
Flat roofs allow you to use all the interior square footage available, and they can offer additional usable space as well. Gardens, solar panels, or a deck are all possibilities for extending the use of a flat roof.
3. They can’t withstand heavy loads
In climates that experience moderate amounts of cold weather, there are concerns that a flat roof cannot withstand the weight of heavy snowfall, but modern building codes require that all roofs can bear the load of the average local snowfall.

With 2026 starting with a burst of cold, wintry weather in the north of England, now is a good time to consider what damage snow and sub-zero temperatures can cause to your flat roofing in Manchester . One potential risk is the formation of ice dams – but what are ice dams, how do they cause damage and what can you do to prevent them? What are ice dams? As their name suggests, ice dams are areas of ice that prevent melted snow and ice flowing off of a roof. They form when the warmth from inside your home hits the roof, melting the snow and ice that has settled on the flat roof. This water then runs off the roof, but if temperatures are still below freezing, as it reaches the colder edges, it can re-freeze, creating a dam. These ice walls hold pooled water on the roof, rather than letting it escape – and it’s this that can cause the damage. On flat roofs, ice dams can also form around depressions in the roof – in other words anywhere that water can sit, you could end up with a pool that is unable to drain. They cause damage because standing water on your roof can seep into the underlying structure if there are any cracks or signs of damage in your roofing material. When ice dams form at the edges of roofs, they can also lead to damp penetrating walls if the pools of melted snow last long enough. How can you prevent ice dams from forming? The best way to prevent ice dams is to ensure that your roof is properly insulated. This will prevent the heat from your home melting the snow that’s accumulated on your flat roof while the outside temperature is still below freezing. Keeping your gutters and drainage channels clear is also essential. This helps to ensure that any snow that does melt has somewhere to go and can safely leave your flat roof. It’s one of the reasons why cleaning your gutters in the autumn is a good idea.

If you’re exploring how to lower your energy bills and reduce your carbon footprint, you may be looking at the likes of solar panels for your home. But what if your property has a flat roof rather than a pitched roof? Can you still install solar panels on a flat roof? The short answer is yes, you can! In fact, it is often easier to install solar panels on a flat roof than it is to fit them to a sloped roof, which might make this an even more appealing avenue to explore when you’re looking at flat roof ideas . In many cases, you also don’t need planning permission to install solar panels on your flat roof. Of course, there are exceptions if you have a listed building or live in a conservation area, but if you own your house (different rules apply for flats too), you should be free to add solar panels to your home as you choose. There are different kinds of mounting systems for flat roof solar panels and which is most appropriate for your home will depend on the direction it faces. It is worth noting that the cost of installing solar panels is often higher on flat roofs because of the mounting system, but some of this can be offset by the lower labour costs because the installation process is usually more straightforward. One of the main reasons homeowners install solar panels is to reduce their energy bills. Many report savings of hundreds of pounds each year, which means these panels often pay for themselves relatively quickly. What’s more, under the Smart Export Guarantee , you can sell any energy you don’t use back to the National Grid, which can increase the rate at which your investment in solar panels pays for itself. So, if you are exploring ways to make the most of your flat roof, consider solar panels as an option to reduce your energy bills and do good for the environment.
