FAQ: How Long Does Your Type of Commercial Building Roof Typically Last?

January 9, 2020

A lot of commercial buildings boast of the excellent roofing durability of their commercial roofs. However, one cannot simply say that their type of commercial roofing stands out above the rest without assessing its materials and structure. In order to determine what type of commercial roof to purchase and install, one must know – how long does your type of commercial building roof typically last?

The lifespan of a commercial building roof depends on its material. Below are roofing materials and their corresponding years they typically last.

Single-Ply Membranes

Single ply membranes are commercial roofs with the lightest weight yet deliver excellent protection, insulation, and lifespan for commercial properties. They are self-adhering but some require heat-welds to install effectively on roofs for effective insulation and protection. On average, you can enjoy from 20-40 years.

Rubber Roofs

Rubber roofs otherwise known as Ethylene propylene diene monomer (EPDM) are common commercial roofing materials. In fact, they’re available in small sheets just in case commercial roofs require repairs. The synthetic rubber sheet can last from 25-30 years with effective maintenance. However, it does not guarantee excellent UV protection if you use the affordable yet monotone black color. In addition, it is susceptible to foot traffic damages.


Polyvinyl chloride (PVC) roofs share the same base ingredient as their water piping counterparts. However, they have added durability and impact resistance with the use of talc and fibreglass on their membranes. PVC roofs have a 30-40 year lifespan too.


Thermoplastic polyolefin (TPO) is the evolution of the traditional EPDM. Instead of using saw and slate dust for membrane reinforcement, TPO manufacturers use talc and fibreglass. It has a longer lifespan of 30-35 years with effective maintenance.

Modified Bitumen

Traditional tar and gravel roofs used waterproof membranes and roofing tar to make a huge membrane sandwich. Unfortunately, tar is a smelly and noxious material that takes time to dissipate. Therefore, manufacturers developed modified bitumen membranes as a quick and convenient modern alternative. Modified bitumen roofs have a lifespan of 25-30 years.

Asphalt Rolled Roofing

Residential asphalt shingles are the most affordable options for homeowners. For commercial property owners, there is asphalt rolled roofing. The asphalt and felt membrane can last only from 15-25 years. In addition, it does not provide excellent protection against possible hailstorms.

Standing Seam Metal Roofs

Standing seam metal is an excellent choice for residential properties too. They offer excellent roofing protection, UV reflection and insulation, and a lifespan of over 70 years even with minimal roofing material maintenance. Furthermore, they are quick to install.
