General Questions
What is a flat roof?
A flat roof is a roofing system usually seen on commercial and industrial spaces. As implied by the name, it has a low slope that is less than 10 degrees. Although it may appear flat, it has a slight incline for water drainage purposes. Access our blog post, Are You Wondering: What is Flat Roofing for a closer look into flat roofs.
How long does a flat roof last?
How long a flat roof lasts depends on several factors, including material and maintenance. That said, they are usable between 2 and 4 decades. Some of the most durable materials are EPDM and PVC. When properly installed and maintained, they can last a long time.
For more information you can refer to our blog post, How Long Can a Roof Last.
What materials are used for flat roofing? (EPDM, TPO, PVC, Torch Down, etc.)?
The most commonly used materials for flat roofing are the following:
- EPDM (rubber roofing)
- Modified bitumen
- TPO (thermoplastic polyolefin)
- PVC (polyvinyl chloride)
Each of these materials have unique benefits to offer. Delve deeper into flat roofing materials by checking our blog post, What is the Best Material to Use When Installing a Flat Roof.
Is a flat roof really flat, or does it have a slope for drainage?
Quite the opposite, a flat roof isn’t completely flat. Most people are misled by the name. Flat roofs have a slight pitch that directs water toward drains or gutters. This slope allows for efficient water drainage and prevents ponding. Find out more about roof pitch by reading our blog post, What Roof Pitch is Good for a Flat Roof.
