Roofing Material Comparison Pros Cons
Rolled asphalt roofs and EPDM (ethylene propylene diene monomer) roofs are both popular options for flat and low-pitched roofs. Both materials have their own advantages and disadvantages, which can make it difficult to decide which one is the best choice for a particular building.
One of the main advantages of rolled asphalt roofs is that they are relatively inexpensive. They are also easy to install, which makes them a popular choice for DIY projects. Additionally, rolled asphalt roofs are durable and can last for many years with proper maintenance. They are also resistant to fire and UV rays, which makes them a good choice for areas with high temperatures and intense sun exposure.
On the other hand, EPDM roofs are made from a synthetic rubber material, which makes them more resistant to extreme temperatures, UV rays and chemical exposure. They are also longer-lasting than rolled asphalt roofs, with a lifespan of up to 50 years. EPDM roofs are also easy to repair and maintain, and they are environmentally friendly, as they can be recycled at the end of their life.
Another advantage of EPDM roofs is that they are available in large sheets, which can make installation quicker and easier. They are also highly flexible and can withstand movement in the building structure without cracking or breaking.
However, EPDM roofs are generally more expensive than rolled asphalt roofs, and they can be more difficult to install. They also require special equipment and techniques to install, which can make them less suitable for DIY projects.
In summary, both rolled asphalt roofs and EPDM roofs are suitable for flat and low-pitched roofs, but they have different advantages and disadvantages. Rolled asphalt roofs are less expensive and easy to install, but they have a shorter lifespan than EPDM roofs. EPDM roofs are more durable, longer-lasting, and environmentally friendly, but they are more expensive and require special equipment and techniques to install. Ultimately, the choice between the two will depend on your budget, the location of your building, and the specific needs of your project.
