RETEX Recently replaced this flat roof in Richmond, VA. But How Long Should A Flat Roof Last?
Flat roofs are a common roof type throughout Richmond, whether for a whole home or on small additions with low pitches. The two main types of flat residential roofs are modified bitumen and single-ply.
Modified bitumen roofs have an estimated lifespan of 15 to 20 years. Meanwhile, a single-ply flat roof – such as a TPO or EPDM roof – can last between 20 and 30 years.
The main disadvantage of any flat roof is any puncture or tear, such as from a piercing tree limb, could threaten the entire structure.
