How Often Do Flat Roofs Need Replacing?
Flat Roof Replacement Frequency: Typically, flat roofs need replacing every 20-30 years, depending on the material and maintenance.
Here are some general guidelines for the replacement frequency of flat roofs based on common roofing materials…
- Built-Up Roofing (BUR) – This type of roofing, which consists of layers of asphalt or tar with reinforcing materials, can last around 20 to 30 years with proper maintenance.
- Modified Bitumen Roofing – Modified bitumen roofs typically have a lifespan of 10 to 20 years.
- EPDM (Ethylene Propylene Diene Monomer) Rubber Roofing – EPDM roofs can last around 20 to 30 years with proper care.
- TPO (Thermoplastic Polyolefin) Roofing – TPO roofs usually have a lifespan of 15 to 20 years.
- PVC (Polyvinyl Chloride) Roofing – PVC roofs can last around 20 to 30 years.
It’s important to note that these are just general estimates, and actual lifespan can vary. Regular inspections and maintenance are crucial for prolonging the life of a flat roof.
