Commercial flat roofs are an integral part of many buildings, offering both protection and aesthetic appeal. Understanding the longevity of these roofs is crucial for building owners and managers to ensure they get the best return on their investment. In this guide, we delve deep into the factors that influence the lifespan of commercial flat roofs and how to maximize their longevity.
Types of Commercial Flat Roofs and Their Lifespans
There are several types of commercial flat roofs, each with its unique characteristics and lifespan:
- EPDM Roofs: Made from a synthetic rubber material, EPDM roofs have a lifespan ranging from 20 to 40 years. They are known for their durability and resistance to UV rays.
- TPO Roofs: TPO, or thermoplastic olefin, roofs typically last between 20 to 30 years. They reflect sunlight efficiently, reducing energy costs during the summer months.
- PVC Roofs: PVC roofs are known for their strength and flexibility, with a lifespan of up to 30 years. They are resistant to chemicals, making them ideal for buildings near industrial areas.
When choosing a roofing system, it's essential to consider both its expected lifespan and how well it suits your building's specific needs and the local climate.

Factors That Can Shorten Your Roof's Lifespan
Several factors can reduce the longevity of your commercial flat roof:
Extreme Weather Conditions
Central PA experiences a range of severe weather conditions, from thunderstorms and hail to heavy snowfall. Such extreme weather can damage the roof, and if these damages aren't promptly addressed, they can lead to more significant problems down the line.
Neglecting Regular Maintenance
Many commercial roofs fail prematurely due to a lack of regular maintenance. A roof that could last 30 years or more might only last 15 to 20 years without proper care. Regular inspections by professionals, like those at Equity Roofing, can save building owners significant amounts in repair and replacement costs.
The Importance of Regular Maintenance
Imagine a scenario where a 10,000 square foot roof, warranted for 20 years, is replaced at a cost of $80,000. Without regular maintenance, simple issues could lead to the need for a complete replacement after just 20 years, costing upwards of $120,000. On the other hand, with yearly inspections costing around $800, the total expenditure over 30 years would be significantly less.
Essential Maintenance for Flat Roof Systems
Seams and Flashing Points
The roof membrane, usually available in 10' or 20' wide rolls, is joined together using various methods depending on the type of roofing system. Over time, these seams and flashing points can become vulnerable and require periodic maintenance to prevent leaks.
Drains
Drains play a crucial role in preventing water accumulation on flat roofs. Regular cleaning is necessary to prevent blockages, which can lead to excessive weight from ponding water and other related issues.
Puncture Repairs
Various factors can cause punctures on a flat roof, from falling branches to carelessly placed equipment. Prompt detection and repair of these punctures are vital to prevent water damage.
