What Is Roofing Felt?
Roofing felt is a material used for insulating roofs. It’s a polymer sheet treated with hot gas to form a foam-like material that acts as a barrier against the elements. Despite its name, this material is not designed to be exposed to the elements for long periods of time. Instead, it serves as an additional layer of protection over the plywood roof deck.

The most common uses for roofing felt include protecting walls and roofs from the elements. It is layered several times, and each layer is designed to provide a layer of protection. The base is usually composed of wood, cellulose, fibreglass, polyester, or some other natural material. The base layer is then saturated with bitumen, a protective coating made from asphalt, which keeps water from penetrating felt fibres. For this reason, roofing felt is made of several layers.
Roofing felt is a highly versatile material that offers several benefits. It protects against heat loss and acts as a barrier between the roof and the elements. It’s typically sold in rolls and applied to the roof’s base (usually plywood) before the final layer of shingles is applied. Depending on the climate of where you live, you may want to consider other insulation products to complement the roofing felt. This article will explain the benefits of using roofing felt in the construction of your home.
Roofing felt comes in two weight grades: 15 lb and 30 lb. For lighter projects, 15 lb felt is recommended. For heavier ones, 30 lb is recommended. The weights of the two roofing felt grades are similar but the 15 lb felt is easier to tear. If you’re looking for roofing felt for a specific job, look for a label that specifies its weight and recommended slope.
Unlike the low water vapour resistance felt, air permeable felt is more resistant to extreme temperature changes and is best for homes located in humid areas. It is also known as ‘Air Open’ underlay and is relatively new to the construction market. If you’re wondering, what is roofing felt, read on! It’s an important material for your home’s roof and it’s worth taking the time to understand its functions.
While most roofing felts last between six to ten years, they can be damaged over time. Cleaning your roof regularly will prolong its life and keep the area from deteriorating. You’ll also need to be sure to keep the area of your roof protected from harsh weather. Some roofing felts can be repaired, while others are not. Make sure you follow the manufacturer’s guidelines regarding care. The best way to care for your roof is to inspect it often and replace it if it becomes brittle.
Underlayment is a crucial part of your roof’s protection. If a shingle fails, a layer of roofing felt beneath it will prevent the home from losing its rating in a fire. Sometimes, the roof deck will become so saturated that it will not be able to cope with the flexing caused by weather. Depending on your climate, this type of roofing felt is more expensive than the other kinds, but it will protect your home from damage caused by extreme temperatures.
