The first thing to consider when it comes to flat roofs is that, if installed correctly with top-of-the-line materials, they can last between 20 and 25 years. If you're nearing this threshold or noticing any abnormalities, such as those mentioned in this blog, it may be time to replace your roof. The type of flat roof material you choose will determine the length of its lifespan. For instance, a flat membrane roof can last 25 to 30 years, depending on the type you choose.
TPO membrane or PVC membrane roofs usually last about 25 years, while EPDM roofs are more durable and can last between 25 and 30 years. Flat roofs can last up to 20 years if properly installed. The durability of the roof depends on the quality of the roof materials and the good maintenance of the roof. On average, a flat roof in a residential or commercial structure needs to be replaced after about 15 years.
However, this lifespan can be extended depending on the roofing materials used and the maintenance schedule followed. The age of a flat roof is often an important factor in determining when it needs to be replaced. Generally, flat roofs have an average lifespan of 15 to 30 years, depending on the materials used and the quality of the installation. Regular maintenance and inspections can prolong this lifespan, but beyond a certain point, repairs become less cost-effective than a complete replacement. Determining when to replace a flat roof involves considering several factors such as regular maintenance, major damage, energy efficiency issues, changes in building use or standards, and future plans.
Investing in a new, durable flat roof will not only protect your building, it will also provide you with peace of mind and long-term cost savings. Before starting the roof replacement process, check with your roofing contractor that both the materials you use and your work are backed by a warranty. But even if you don't notice any signs that your flat roof needs attention, it must be sealed every five years to protect it from water damage. If your building undergoes a change of use, such as a renovation or expansion, it is essential to assess the condition of the existing flat roof. If you're not ready to make the full commitment to replacing a flat roof, you have several different alternatives. You can follow instructions and guidelines to install a flat roof without an expert's help.
However, if there is damage that needs to be repaired or replaced, it's better not to spend money on lining it but to fix the problems instead. The best way to prevent roof leaks and extend the life of the flat roof is to ensure that moisture drains properly. If you're a building manager, owner, or caretaker, it may not always be immediately apparent that your flat roof requires attention. That's why it's important to invest now in a high-quality flat roof replacement with professional and expert installation so that you can rest easy for many years to come.
