What is Felt Roofing Roll?
Felt roofing roll is a type of roofing material made from a felt-like substrate that is saturated with asphalt. It is primarily used for waterproofing flat roofs, but can also be used in various roofing applications. The rolls come in large sheets, making them easy to apply over large surface areas.
Composition and Structure
The primary components of felt roofing rolls include:
- Felt material: Typically made from fiberglass or organic materials.
- Asphalt: Acts as a waterproofing agent.
- Granules: Some felt rolls are topped with mineral granules to enhance durability and UV resistance.
Types of Felt Roofing Roll
There are two main types of felt roofing rolls: organic and fiberglass. Understanding the differences between these types will help you choose the right material for your roofing needs.
Organic Felt Roofing
Organic felt is made from natural fibers such as cellulose. It is thicker and provides excellent insulation properties. However, it is more prone to moisture absorption, which can lead to mold growth over time.
Fiberglass Felt Roofing
Fiberglass felt is made from synthetic fibers and is more durable and moisture-resistant than organic felt. It is lighter and easier to handle, making it a popular choice for contractors.

Felt roofing rolls offer several advantages that make them a popular choice among homeowners and contractors alike:

- Versatility: Suitable for various roofing applications, including flat roofs and low-sloped roofs.
Disadvantages of Felt Roofing Roll
While felt roofing rolls have many benefits, they also come with some drawbacks:
- Shorter Lifespan: Compared to other roofing materials like membrane roofing, felt rolls may not last as long.
- Moisture Issues: Organic felt can absorb moisture, leading to potential mold growth.
- Less Durable: Felt roofing may not withstand extreme weather conditions as effectively as other materials.
Installation Process
The installation of felt roofing rolls can be done in several steps:
Preparation
Before installation, ensure the roof surface is clean and free of debris. Inspect for any damage that needs to be repaired.
Application
- Roll out the felt roofing material, starting from the lower edge of the roof.

Maintenance Tips
Maintaining your felt roofing is essential for longevity:
- Regularly inspect for cracks or damage.

Common Misconceptions
There are several misconceptions surrounding felt roofing rolls:
