What Is Roofing Felt?
2 October 2020
If you’re considering a flat roof extension at the moment, it’s important to give good consideration to the types of materials you could use for the project and roofing felt is a great choice for a project of this kind, able to be used on flat roofs but also garages and garden sheds, so if you’re looking for versatility, you’ll find it here.
The product itself is made up of two or three layers of felt, usually coated with waterproofing of some kind, to create an impenetrable barrier that prevents water ingress… very important for a roof, especially in the UK where we’re blessed with lots of rain.
There are all sorts of benefits associated with felt as a roofing material, but the main one is that it’s a very durable option and can protect your home from whatever the elements choose to throw at it over the years.
It’s strong and durable, and can be used on any size of project, big or small - and it can be used on any kind of surface, so ideal for your flat roof, but also any curved or pitched areas you have on the property.
Another benefit is that your home will enjoy a greater level of insulation thanks to roofing felt, helping to trap heat in the house where it belongs. Your home loses a lot of its heat through the roof so anything you can do to help prevent this will make your property more eco-friendly and help save you money on your energy bills… so it’s a win-win for all!

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.
