Both products serve similar purposes in waterproofing and protecting roofs, but they have distinct characteristics that make them suitable for different applications.What is Tar Paper?Tar paper, traditionally made from a base of paper saturated with tar, is known for its durability and excellent water resistance. It’s primarily used as an underlayment in roofing to provide a barrier against moisture. Tar paper is particularly effective in environments with heavy rainfall or snow.What is Roofing Felt?Roofing felt, on the other hand, is made from fibers like cellulose or polyester, soaked in asphalt or bitumen. Similar to tar paper, it serves as a moisture barrier but is generally lighter and easier to install. Roofing felt is available in two types: organic (made from natural fibers) and inorganic (made from fiberglass). The choice between the two may depend on personal preference and the specific requirements of the roofing project.Key Differences Between Tar Paper and Roofing FeltWhile both tar paper and roofing felt can be used to protect roofs, their differences can influence your decision:CompositionTar paper is typically heavier and more robust due to its tar content, whereas roofing felt is lighter and easier to handle.Water ResistanceTar paper offers superior water resistance, making it ideal for extreme conditions, while roofing felt is suitable for normal applications.Installation EaseRoofing felt is easier to install due to its lighter weight, making it a preferred choice for many contractors.Which One Should You Choose?Choosing between tar paper and roofing felt ultimately depends on your specific needs and the conditions of your roofing project.
