Why Commercial Flat Roofs Need Maintenance
Commercial flat roofs are a smart investment for Calgary’s businesses, but they require regular maintenance to make sure they stand up against the weather and other factors.
Preventative maintenance prevents costly repairs and can double the lifespan of a roof.
Calgary’s brutal weather—load-bearing snow in addition to dense, heavy rain and freeze-thaw cycles—make all roofs pool and leak. With proactive care, any underlying soil integrity issues can be caught in time, protecting important assets and avoiding costly interior damage to walls, ceilings, and floors.
By ensuring a watertight seal, maintenance prevents moisture intrusion and resultant growth of mold, which is essential for protecting sensitive HVAC systems and preventing increased energy consumption. According to the study, proactive routine inspections and maintenance can prevent 60-80% of all roof leaks, protecting the roof’s value and functionality.
By doing so, possible dangers are minimized on-site, creating a safer working environment.
Spring Maintenance Checklist for Flat Roofs
Spring is an ideal time to inspect and maintain your commercial flat roof, ensuring it stays in excellent condition for years to come.
Start by removing debris such as leaves and branches. These can cause moisture to build up and damage your roof.
Next, check drainage systems, such as scuppers and downspouts, to make sure water drains properly and doesn’t build up. Inspect for wear in flashing, seams and the roof membrane. Ninety percent of leaks begin as cracks in these materials.
Regularly clean and inspect your gutters to ensure no water collects and creates ponding or leaks. Consider using a flat roof inspection checklist to note problems, such as blistering, bubbles or wrinkles in the membrane.
Catching issues early will help maximize your roof’s service life. If given the attention it needs, your roof can enjoy a lifespan of 25 to 30 years!
Inspecting for Common Flat Roof Problems
Flat roofs on Calgary commercial properties face particular issues. Unfortunately, the region’s harsh temperature extremes and repeated cycles of melting snow or rain produce real challenges with upkeep and longevity. Conducting regular inspections, no matter how small your flat roof is, is key to nipping any potential problems in the bud.
One main issue with flat roofs is water pooling. This problem is usually due to the common 2% to 4% slope, and if it’s not corrected promptly, it can result in damaging leaks. Membrane damage, such as cracks and tears caused by expansion and contraction, is a major problem. If clogged drains are preventing proper water runoff, this creates even bigger problems.
Pay special attention to trouble spots such as flashing, skylights, and roof penetrations. Either with binoculars from the ground or a ladder, check these areas and take photos of any observed damage, such as discoloration or cracks.
Proper insulation and ventilation help with energy efficiency and prevent moisture accumulation, which can lead to serious damage.
Effective Flat Roof Repair Techniques
Commercial flat roofs in Calgary need specific care to maintain their durability and performance. For smaller leaks, localized repairs with materials such as rubber patches or modern elastomeric sealants can deliver water-tight protection quickly and affordably.
Small punctures and tears in the membrane may be repaired through surface patching procedures. This creates the most seamless repair allowing the roof’s integrity to be maintained.
Waterproof coatings, which can be applied directly from the bucket, add an extra level of defense, extending life expectancy. Conduct regular inspections—at least twice a year, preferably every spring and every fall.
Inspection is critical, catching vulnerabilities while they’re minor and avoiding expensive repairs. When well maintained, flat roofs, such as EPDM systems, can last 30 years or more. Taking the time to invest in proactive care will save you money over time.
Proactive Maintenance Strategies for Longevity
Taking a proactive approach to flat roof maintenance and restoration is key to maximizing a roof’s longevity and performance. Having a regular maintenance program, even if that means two inspections a year, preferably in the spring and fall, can help catch problems before they worsen.
Regularly clearing debris, especially around drains and scuppers, can keep them from clogging, which would direct seawater under your deck to damage the structure below. Repairing minor issues as soon as they arise, like small punctures or areas of puddling water, prevents them from developing into expensive damages down the road.
These home maintenance projects require high-quality materials and professional services to be truly effective. The truth is that 80% of roof leaks are due to poor installation or lack of maintenance.
Calgary’s extreme weather conditions such as heavy snow and high winds require additional caution to ensure you are properly protecting your investment.
Calgary's Building Codes and Regulations
Working with Calgary’s strict building codes and regulations is key to keeping commercial flat roofs safe and in compliance. What makes Calgary unique is its proactive approach.
The City of Calgary administers the Building Maintenance Bylaw, a pathbreaking regulation that applies to all buildings over five stories to minimize safety hazards. Compliance doesn’t stop there with this bylaw. It incorporates the National Building Code — Alberta Edition, which makes different provisions for buildings below five storeys and above that threshold.
Licensed contractors who know these details inside and out will not only get you in compliance but save you from being penalized. When only 1% of a five-year maintenance budget goes to repairing existing infrastructure, proactive planning becomes a necessity.
