Extending the Lifespan of Your Commercial Roof

The longevity of commercial roofing systems varies, and inevitably, they will all require replacement. The lifespan of your roof depends on your specific type, and there are distinct warning signs that signal when a replacement may be necessary.

No matter the material or roofing system in place, the cost of replacing a commercial roof is considerable. Ignoring your roof until problems become unavoidable is ill-advised. Regular vigilance and inspections are essential for assessing the condition of your roof, either by conducting them personally or through an annual professional check by a commercial roofing expert. This article aims to guide you through recognizing these warning signs and help prevent early roof replacement due to overlooked minor issues.

How Long is A Commercial Roof Good For?

Commercial roofs come with varying lifespans, and it’s crucial to have a ballpark figure of how long yours is expected to last. Commercial roofing systems, such as PVC, EPDM, and TPO typically last between 20 to 30 years. Metal roofing can extend up to 60 years but they do come with the downside of being less energy efficient. Slate, clay, or concrete options have impressive longevity, lasting between 70 and 100 years, but are most suited for regions with minimal rainfall.

Remember, the durability of a commercial roof is greatly influenced by how well it is maintained. Regular inspections and timely repairs of minor issues can significantly prolong the life of your roof. So asking the question, ‘how long is a commercial roof good for?’, should be qualified with the additional question of, ‘are regular inspection and maintenance programs a service I plan to utilize long term’?

Interior Leaks

When it comes to internal signs of leakage, the evidence is usually unmistakable. If water is dripping from the ceiling or puddles form on the floor following a rainstorm, it’s a clear indicator that a roof replacement might be imminent or at the very minimum repairs are needed. Nevertheless, some signs are not as overt and require a keener eye.

Mold growth is a definitive sign of moisture problems and can pose serious health risks, potentially triggering asthmatic conditions. Furthermore, the presence of musty smells can also point to moisture intrusion. Visible damage or stains on ceiling tiles or walls usually signify a severe leakage problem, suggesting that a roof replacement may be necessary.

When Commercial Roof Seams Fail

Roof seams are a common source of trouble in various roofing systems. PVC and TPO roofs have their seams thermally fused, while EPDM uses a special adhesive tape. The once-popular modified bitumen roofs rely on hot tar and overlay materials for sealing seams. Over time, these seams may fail due to improper installation or just the natural weathering/normal wear and tear, leading to leaks. It is critical to have a trusted roofing professional inspect these seams regularly to prevent significant damage.

Regardless of the roofing system in place, when seam breakdown occurs, it typically indicates a need for roof replacement. Incorrect installation can lead to early seam deterioration. However, it is usually the relentless wear and tear from weather and environmental conditions that weaken these critical joints over time. When the integrity of the seams is compromised, moisture infiltration becomes an issue, often leading to the necessity for a new roof or significant repairs. To prevent such issues from escalating, it is essential to have your roof’s seams inspected by a qualified roofing contractor.

Semi-annual roof inspections, preferably in the spring and fall - heading into winter - are highly recommended tasks to ensure your commercial roof has the longest lifespan possible

Perforation in the Roofing Membrane

Tears or punctures in the roofing membrane need immediate attention from a roofing specialist to assess whether it’s an isolated issue or a sign of general wear, particularly in older roofs.

Large rooftop equipment, such as HVAC units, often necessitates maintenance work that can inadvertently damage the roofing membrane. Therefore, it is wise to schedule a roofing inspection following any such repairs or installations.

Breakdown of Rubber Over Time

The synthetic rubber commonly used in roofing, particularly EPDM, is subject to deterioration due to the continual cycle of expansion and contraction with temperature changes over the years. When the material can no longer withstand these fluctuations, it may be time to consider a roof replacement.

How To Extend the Lifespan of your Roof to the Greatest Extent

Nothing is more crucial than regular inspections and maintenance to ensure your commercial roof reaches its full lifespan potential. Not only is this approach cost-effective, but it also prevents minor defects from developing into severe, costly problems that could necessitate an entire roof overhaul.

It is recommended to have a certified and insured commercial roofing contractor conduct an annual inspection of your building. Beyond the regular semiannual roof maintenance inspections, additional inspections after severe weather events are highly recommended and can help identify and remedy any serious damage caused.
