What is the life span of Modified Bitumen roofing?

Modified bitumen roofing typically has a lifespan of approximately 14 to 20 years. This type of roofing is often used for low-slope applications and is made using polymer-modified asphalt, which provides improved elasticity and durability compared to traditional asphalt roofing. The materials and manufacturing processes involved in modified bitumen allow for resilience against weather conditions and the potential for installation in various climates, contributing to a relatively long lifespan within the specified range.

Additionally, the maintenance of modified bitumen roofs can influence their longevity, with regular inspections and repairs able to extend their useful life closer to the upper limit of the 14 to 20-year range. This information is crucial for homeowners and inspectors alike, as understanding the expected lifespan helps in planning for future maintenance or replacement.
