Felt is a popular flat roofing material. It’s most typically found on shed and garage roofs.
Previously, felt was fitted on roofs using hot bitumen. This process was time-consuming and made roofs that didn’t last particularly long. Now torch-on felt is the best thing to use. You apply it in sheets using a blow torch to make one side sticky and layer it on.
Lots of homeowners decide to use felt to cover their flat roof as it’s relatively inexpensive and lightweight. We’ve made a list of its advantages and disadvantages to help you decide if felt is the right roofing material for you.
One benefit to felt is that it’s light-weight. This means that you can fit it on smaller, weaker structures like sheds, as well as more robust buildings.
Another advantage to felt is that it’s inexpensive. It’s much more affordable than other roofing materials like asphalt, rubber, fibreglass and PVC.
Another reason why people choose felt is because it’s repairable. If it gets worn or torn, it’s easy to torch a new felt patch over the damaged area.
Felt is also flexible. You can cut or join it together to fit any size or shape of roof. It also comes in numerous colours, including brown, purple, grey and green.
Felt has a relatively short lifetime compared to other roofing products. Felt roofing normally lasts for about 10 years, whereas asphalt, rubber, fibreglass and PVC can last 25+ years.
Prone to weather damage
Unfortunately, felt is prone to weather damage. It can get soft and warp out of shape in hot temperatures. In winter it can become brittle and in prolonged sunshine it can fade and weaken.
Repairs can look scruffy
Although felt is repairable, the outcome can often look scruffy. So while you can keep your roof water-tight by torching patches over damaged areas, you may prefer to replace the whole thing, which will cost you more.
