While felt roofing is very common on flat roofs, it is quite different from other roofing methods. It is actually made of several layers of felt sheets. Two or three of these sheets are woven on top of one another and covered in tar to prevent moisture from seeping in. While felt sheets are not terribly strong on their own, several layers together can make a powerful barrier.
Felt flat roofing is generally used on sheds, home extensions and gardening structures.
Felt roofing has been around for a long time, which means that not only has it proven itself as a durable roofing material, but it can also be applied in a variety of ways. It is also very good at keeping out water, even during heavy rainfall.
Its high wind resistance means that even when stretched over a small structure, the material will hold. Other materials, such as shingles may not be able to stand up to high winds, but felt roofing offers some of the best wind resistance of any roofing material.
And this versatile material is suitable for any size of job. While it is most commonly used on small structures, it is also durable enough to be used on larger ones as well.
And if your structure requires a fat roof, you want something that is impermeable by any liquid and that won’t absorb water. Shingles wood and other materials can soak up water over time, causing them to curl or warp. But felt roofing, when covered in a coating of tar, simply repels the water and prevents its ingress. This is why it is often the roofing material of choice for structures with small, flat roofs. The owners don’t have to worry about heavy rainfall damaging their roof and requiring repairs every so often.
