Have you been wondering: what is the lifespan of a flat roof? We explore how many years a flat roof lasts and the options for flat roof materials.
How many years does a flat roof last?
Most traditional flat roofs tend to be made up of asphalt or mineral felt; they usually have an average lifespan of approximately 10-15 years. Over the years, flat roofs have garnered a relatively bad reputation for their ability to become damaged from pooling water or leaks.
However, if you ensure that your built-up roof is well-maintained, your flat roofing material can last you much longer. Many flat roofs in the modern-day tend to last around 20-30 years before you require a replacement. Since plastic and rubber materials have been introduced, you can sufficiently extend the shorter lifespan before replacing them.
What are the options for flat roof materials?
For those looking to improve without a more traditional type of roofing option, you may wish to consider materials like TPO and EPDM. You can select from more hardwearing options like lead, concrete tiles, copper, fibreglass and zinc, or choose rubber roofing. EPDM and TPO offer a relatively longer lifespan than traditional materials.
Here are reviews of some of the most popular residential and commercial roofing options on the UK market:
Why Do EPDM Roofs Last Longer Than Other Materials
EPDM chemical structure is created through carbon black, a highly resistant material to degradation and decomposition that many products can retain from frequent UV exposure. EPDM is highly flexible; its properties can expand and contract if temperatures become too hot or cold.
The material is best at withstanding strong winds and extreme weather conditions as its synthetic rubber composition makes it completely waterproof. Its longevity was proven in 2010 by the ERA (EPDM Roofing Association in Washington DC.
The study tested roof membranes and tiles samples approximately 30 years old, carefully evaluating their physical and mechanical properties. Such properties tested include water absorption, tear-resistance and tensile strength. Its result was highly positive, providing that the samples met all minimums and standards even after 30 years of exposure to the elements.
Benefits Of EPDM Rubber Roofing
There are many benefits to EPDM rubber roofing to discover, the following include:
HOW TO MAINTAIN A FLAT RUBBER ROOF
Maintenance for your flat roofing material doesn't have to be a chore; however, it's something you must ensure you carry out maintenance and inspections a few times a year. The most suitable time of the year is once in the spring to assess the dampness and cold from the winter months and its potential effect on your roof.
We encourage you to do so once in the autumn to see if the sun's rays cause any moisture damage in the hot summer months. It may be worth checking the roof after spouts of heavy rain or harsh weather like a hailstorm or heavy snowfall.
Ensure there is no water pooling on top that requires removing. When carrying out bi-annual inspections and maintenance, it's essential to remove any leaves from the roof, dirt, and debris that could eventually cause drainage system issues by blocking water from properly draining, causing it to pool or potentially clog.
For those with overhanging trees and branches that dangle over your roof, it's best to cut them off, alongside heavy branches that could damage the rubber membrane material if it fell on it. Like any other roof, you must be prepared to undertake the occasional repair every once in a while; you can do so as a DIY project with inexpensive repair kits fit with patches for straightforward maintenance of any EPDM roof.
ISSUES THAT CAN AFFECT THE LONGEVITY OF A FLAT ROOF
The primary reason people have worries about purchasing households with flat roofing is its problems with life expectancy and the factors that can affect it. The flat roof's lifespan will typically depend on the manufacturers' materials to produce the roofing, so it's paramount to ensure you do inspections on your home every once or twice a year for proper maintenance.
A poorly installed flat roof is also likely to underperform in terms of effectiveness. It's best to utilise the help of a talented professional to complete the work for you, or you can do so yourself by taking the time to carefully follow the instructions. The best way to complete said task is to choose the most efficient, high-quality material on the market, ideally from a reputable dealer in your local area.
Correct installation and high-quality EPDM will ensure that your new roofing is a long-lasting investment, so don't let the expected lifespan put you off your purchase.
