When you’re an entrepreneur building your own commercial establishment, picking the correct roofing system can be a bit challenging. Flat roofs are ideal for rooftop equipment like HVAC systems and solar panels, but do require regular maintenance. On the other hand, metal roofing is far more durable, but roofing contractors charge a pretty penny in upfront installation fees. If you’re trying to decide which roof would be best for your own business facility, the following article does a commercial flat roof vs metal roof comparison.
Contrasting Commercial Roofing: Metal VS Low Slope
Are you leaning toward flat roofing for your office building? Or do you want to go the standing seam route instead? While both options are tempting, there are a few things that can help you make the correct decision for your needs. Things such as the lifespan of the roofing systems along with the drainage concerns should be seriously considered when choosing between the two.
Here is a list of factors that you should keep in mind when roofing your business.
Installation Cost
As a smart businessman, the first thing you should be looking at is the investment. Flat roofing systems, such as TPO and BUR, cost an average of $5-10 per square foot. On the other hand, metals, like zinc and steel, are more expensive at $8-15 per square foot. So, pick what fits your budget.
Installation Purpose
What exactly do you need the roof for? If you want something like a rooftop dining area or a place to house your HVAC system or solar panels, then a flat roofing system is the correct choice. However, if it’s a durable roof for your commercial property, then metal roofing is a better option.
Roofing Lifespan
Next, let’s see how long each roofing option lasts. Depending on the material and membrane, flat roofs require replacements in about 15-30 years. Conversely, metal roofing is celebrated for being a long-term roofing solution of 40-70 years instead. So, definitely keep your long-term goals in mind.
Water Drainage
Are you located in a rainy city? Flat roofs are notorious for having ponding issues due to the low slope—which leads to material degradation and premature replacements. However, when you consider the pros and cons of metal roofing for businesses, remember that it encourages fast runoff.
Maintenance Considerations
No matter the roofing system you choose for your business, you’ll need to keep up with it. Flat roofing is vulnerable to punctures and UV damage and demands routine sealing. On the other hand, metal roofing systems only require routine cleaning to continue performing well.
Weather Resistance
Your roof protects your investment, so naturally you’d want a system that can take the beating. If your business is located in a moderate climate, flat roofing will work just fine. However, if it’s extreme heat, high-speed winds and hail that you’re experiencing, pick metal roofing instead.
Energy Efficiency
Energy-efficient commercial roofing systems don’t just lower utility bills—they keep indoors comfortable, which boosts labor productivity. While flat roofs are highly energy efficient; metal roofing just doubles the effect thanks to its material and the coating on top. So, choose carefully.
Installation Timing
Do you want a commercial roofing system that goes up as soon as possible? Or are you alright waiting? If it’s the former, then a flat roofing system, whether it’s TPO EPDM or something else, would be perfect. However, if you don’t mind the extra time the roofers will need, then pick metal roofing instead.
Structural Work
Metal roofing is known to be heavy. This is why, before the commercial roofers put it up, they need to reinforce the structure underneath. On the other hand, if you want to avoid the hassle, time and expense of reinforcing your building, then flat roofing is the better choice.
Long-Term Value
Do you want a roofing system that yields a quick return on a limited budget? Then a commercial flat roof is the way to go! But, if you’re interested in gaining long-term value through a durable roofing option instead, then a metal roofing system wins by a longshot.
To Summarize
In conclusion, when you do a commercial flat roof vs metal roof comparison, you should consider the following factors. Take into account the durability of the roofing system; think about the energy efficiency; and also look into the future and consider ROI.
