A lot of Edmonton’s business owners believe that spring is the best season for commercial roofing projects, while knowledgeable facility managers and property owners know a well-kept secret: September is the best month in Alberta’s capital for replacing commercial roofs. Once summer winds down and fall starts creeping in, this “hidden” season comes with some big perks that will save money, keep your business running smoothly, and sets you up for long-term success.
Perfect Weather for Big Projects
September weather in Edmonton normally ranges from 7°C to 18°C. That’s just ideal for roofing crews to work efficiently without the extreme heat of summer or the inclement weather of October and November.
Roof replacements may take weeks or even months, so weather consistency is a must. September’s typically dry conditions minimize weather-related delays that can devastate project timelines and budgets, unlike the unpredictable weather of spring. This means fewer interruptions to your daily business.
Less Impact on Business Operations
For many businesses, September marks a slower period – after the summer rush, but before the holiday season picks up. Patios start to close, retail stores see fewer customers, and companies often schedule maintenance. This makes it way easier to fit in a big roofing job without disrupting daily operations.
For example, restaurants don’t have to worry as much about debris falling near customers, and retail shops can plan work around inventory schedules. Company facilities can even line up the roof work with equipment maintenance for maximum efficiency.
Better Access to Skilled Contractors
By September, roofing companies aren’t slammed with emergency repairs from hailstorms or rushing to beat the snow. This means they can send their best crews to focus fully on your project.
With fewer distractions, they can really take their time with details like drainage, flashing, and membrane installation, all things that make a big difference in how well your roof holds up.
Materials Perform Better in Moderate Temperatures
In fact, temperate weather improves the performance of roofing materials including modified bitumen, TPO, and EPDM. Without the strain of intense heat or cold, they stick, seal, and cure more effectively.
Fits Nicely into Budget Cycles
September is the ideal month to spend any remaining operational budget because many Edmonton firms end their fiscal year in December or March. By doing the roof now, businesses may still allocate funds for it this year and still have time to consider future improvements.
Gives You a Winter-Ready Roof
Getting the work done in September means your new roof will be completed before the snow and ice arrive. That’s important for businesses who can’t afford to risk leaks or downtime in the winter, such as retail establishments running into the holiday rush or warehouses holding temperature-sensitive products.
Part of a Smart Maintenance Plan
Likewise, replacing your roof in September coincides nicely with other seasonal maintenance duties, such as building upgrades or HVAC (Heating, Ventilation, and Air-Conditioning) maintenance. It’s a way of preventing issues before they occur rather than rushing to make repairs after the events.
Final Thoughts
Savvy Edmonton business owners see September as a strategic timeframe, not just another month on the calendar. It’s beneficial due to the perfect weather, the availability of contractors, the cost savings, and the minimal business disruption. And if you’re ready to make the most of this perfect timing, MTM Roofing Service has the expertise, crews, and high-quality materials to get your commercial roof done right.
