Rolled roofing emerged during the late 19th Century and it became a common roofing material for low plane roofs. One of the best things about roll roofing is that it is a low cost option that you can use on small areas such as over sheds, garage, and a flat roof.
There are different types of rolled roofs that you can use depending on the square foot you are trying to cover and your area’s weather.
There are also plenty of things that affect the durability and lifespan of rolled roofs, and this guide will tell you all about the basics.

What Is Roll Roofing?
This roofing material consists of 2 or 3 layers with asphalt composite and a felt base. Some rolls are self-adhesive, some are nailed down on the roof, and some require heat welding during the installation.
The reason why most people go for rolled roofing over shingles when it comes to low plane roofs is primarily the cost.
Depending on the material, roll roofing can cost anywhere between $1.50 and $6 per square foot. Most architects recommend metal or rolled roofs for flat surfaces as it provides better insulation and coverage.
Rolled Roofing Materials
Flat roofs are available in rolls, which might make you think that their application is easy but handling them can be quite difficult. Typically, a roll is 6 to 20 feet wide and 100 feet long. Most of the rolls contain rubber or a combination of different materials.
Following are the most common types of roll roofing materials:
This is one of the least expensive roll roofing options. It is widely used in residential areas and is usually made from sawdust, slate dust, or recycled tires.
This roofing material is the easiest to install by overlapping the sheets on a flat roof. The three major benefits of rubber roofing are that it’s cheap, easily maintainable, and durable.
This roofing has an oil-based, mineral surface. It is made of fiberglass mat or thick organic, felt. The roll itself is saturated with asphalt and then topped with mineral granules that offer benefits such as sunlight reflection and impact resistance.
While this roll roofing material is cheap, it is less durable than rubber. On the other hand, it can be installed pretty quickly, which saves you a lot of money on labor.
This roofing material comes at a spot above rubber roofing and is made by combining three materials — sawdust, slate dust, and recycled tires. The reason why EPDM roofing is better than rubber roofing is because it very lightweight but still durable. It is inexpensive and can be easily installed due to the adhesive seams. This prevents any leaks and makes the material last longer.
This roofing material is popular due to its cost. It is made from a combination of ethylene-propylene and polypropylene rubber. However, its manufacturing differs from company to company, which is why its quality and durability vary greatly.
In general, TPO roofing is quite durable. It is cheaper than EPDM and its white color provides heat resistance. Moreover, it prevents mildew and algae growth and is corrosion-resistant.
This roofing material is another form of asphalt roofing that has now become available in rolls. You can find it in cold-press adhesive or self-adhesive with the seams fused together. The right bitumen roll can outlast all roofing materials and if maintained properly, it can last for more than 20 years.
How Long Does Rolled Roofing Last?
As explained above, every rolled roof is made from different materials, which makes some less durable and others highly durable. Let’s have a look at the lifespan of each roofing material:
- Rubber: 20 years
- Asphalt: 5 to 15 years
- EPDM: 20 to 30 years
- TPO: 20 years
- Bitumen: 12 to 20 years
