Deciding on an asphaltic roof coating can feel a bit overwhelming, especially when determining which is right for your roof. Between fibered and non-fibered coatings, no one is better than the other. Each one has their own benefits and it really depends on a number of things such as roof type or climate.
Let’s explore the difference between fibered versus non-fibered roof coatings, and then explain how each is typically used, so you can make an informed decision on which product is best for you.
A fibered roof coating is infused with fibers (usually fiberglass) in addition to the basic materials used for the coating itself. These fibers can be very small in size or relatively large. The fibers are used to increase the strength of the roof coating and make it more resistant to tears and breaks. However, this strength comes at the expense of elasticity.
As the name suggests, a non-fibered roof coating is a substance that does not include the infusion of fibers. Non-fibered coatings have more elasticity and stretching capability when cured, but they may not resist tears and abrasions as well as fibered coatings.
The answer to this question truly depends on the intended application because both coatings have their uses. Factors that may play into your decision include the type of roof/substrate, the total surface area and the climate and weather conditions to which the roof may be exposed.
As a basic rule of thumb, you’ll lean toward fibered coatings when your priority is strength and resistance against tears and abrasions, while non-fibered coatings work best for applications that require greater flexibility and the ability to stretch the material farther over a surface area.
