Whether you’re building a new commercial property or renovating an existing one, the roofing system is crucial. It must be durable and long-lasting while also being aesthetically appealing and cost-effective.
The materials used on a commercial roof depend on many factors, including the structure of the building and climatic conditions. A good roofing contractor, like Roofing Companies Columbus GA know how to pick the best roofing material for your building.
Flat roofs are popular on commercial buildings because they allow space for rooftop gardens and terraces. These features help to improve the air quality inside a building and keep employees cool during hot weather.
A properly installed flat roof also provides a solid base for HVAC and ventilation systems, which can be placed on top of it for maximum durability and performance. This feature is particularly important on large commercial buildings, where heavy equipment can weigh down the roof.
Before a commercial roof is installed, the layout needs to be carefully planned to ensure that all of the necessary weight is evenly distributed. This is especially important for large buildings with HVAC units on top, which can cause the roof to sag and create additional water storage areas.
In addition, the layout design should incorporate a drainage system to prevent the buildup of water on the roof surface and to prevent it from pooling in any vulnerable areas. This can be done with gutters or drains strategically placed around the building to help direct water away from the building’s structure.
Thermoplastic polyolefin (TPO) membranes are a popular choice for flat roofs due to their strength and resistance to hail and high winds. They also repel age-accelerating factors that can weaken a roofing membrane over time, such as mold growth and dirt.
Another option for a flat roof is a built-up roofing (BUR) system, which consists of multiple layers of bitumen and fabric felts bonded together with either hot or cold seaming. These layers are referred to as “plies.”
There are many different flat roofing materials available for commercial buildings, including EPDM synthetic rubber and thermoplastic polyolefin. Each type offers its own set of advantages and disadvantages, so it’s important to choose the one that best fits your building’s needs and budget.
Thermoplastic polyolefin membranes are a good choice for flat roofs that are located in warmer regions, since they can reflect heat and keep the temperature inside the building lower than it would be without the membrane. They also resist heat damage and age-accelerating elements like UV rays.
The intense heat of summer can cause a lot of damage to your commercial roof. This can include problems like leaks, structural damage, and ice dams that could lead to the collapse of your building.
Aside from the extreme temperatures, your roof may also be exposed to high levels of ultraviolet (UV) radiation. UV rays degrade the chemical bonds in your roofing materials, which could eventually lead to premature roof failure.
Another problem that can occur due to the extreme heat of summer is thermal shock. This occurs when your roof reaches very high temperatures during the day and then cools off quickly at night. This sudden change in temperature can cause the roof to expand and contract, causing the roof to warp or develop gaps over time.
One of the most common ways that high temperatures can damage your commercial roof is by putting pressure on your fasteners and seams. This can lead to your fasteners moving out of place or the seams separating.
It can also cause your roof to lose its water-repellent properties. This can lead to your roof absorbing too much moisture, which can cause your roof to rust and rot if left untreated.
Finally, high temperatures can dry out the oils in some of your roof’s materials. This can make them brittle and break down over time, which can lead to cracks or holes in the roof.
