Flat commercial roofs are a vital component of any building since they shield the building’s interior from the weather and provide insulation for the space within the building. However, like any other roofing system, flat roofs have a limited lifespan, and over time, they will need to be replaced.
In this article, we will discuss the different aspects of commercial flat roof replacement and what you need to know before embarking on this project. Firstly, it is essential to understand the signs that indicate that a commercial flat roof needs to be replaced. Some of these signs include visible cracks or tears, water pooling, leaks, or sagging. If any of these signs are present, it is crucial to act quickly to prevent further damage to the building’s interior.
Once it has been established that a commercial flat roof needs to be replaced, the next step is to determine the type of roofing material that will be used. There are several options available, including EPDM (Ethylene Propylene Diene Terpolymer), TPO (Thermoplastic Olefin), PVC (Polyvinyl Chloride), and modified bitumen. Each material has its advantages and disadvantages, and the choice will depend on several factors, such as budget, climate, and the building’s intended use.
EPDM is a popular choice for commercial flat roof replacement due to its affordability and durability. It is a synthetic rubber roofing membrane that is easy to install and requires little maintenance. However, it is not as environmentally friendly for commercial flat roof replacement as some of the other options, and it may not be the best choice for extreme weather conditions. PVC roofing is another durable and energy-efficient option that is resistant to UV rays and extreme weather conditions. However, it is a more expensive option than EPDM and TPO.
Modified bitumen roofing is a type of asphalt roofing that is reinforced with a polyester or fibreglass mat. It is a cost-effective option that is easy to install and repair. However, it is not as durable as some of the other options and may require more frequent maintenance. The next step in commercial flat roof replacement is to select a contractor to carry out the work. It is crucial to choose a reputable contractor with experience in flat roof replacement. The contractor should be licensed and insured, and they should provide references and a detailed estimate of the work to be carried out.
During the roof replacement process, it is essential to ensure that safety measures are in place to protect the workers and the building’s occupants. The contractor should have the necessary safety equipment and should follow all local and national safety regulations. The roof replacement process typically involves removing the existing roof material, repairing any damage to the roof deck, installing insulation, and installing the new roofing material. The contractor may also install additional features, such as skylights or solar panels, depending on the building’s needs.
After the new roof has been installed, it is important to carry out regular maintenance to ensure that it remains in good condition. This includes regular inspections, cleaning, and repair of any damage. Regular maintenance will extend the life of the roof and prevent costly repairs or replacements in the future.
