The life expectancy of a roof depends on a lot of different factors. Things such as roof design, climate, quality of installation and regular maintenance can determine how long your roof lasts. But above all, the lifespan of your roof will depend on the material it’s made of.
Let’s explore some of the most common materials and how long you should expect them to last.
Metal roofing systems usually last longer than any of their competitors, with a lifespan of anywhere from 40 to 70 years. This is an impressive number but you will need to meet a few criteria to get the most from your metal roof.
Choosing quality brands like Metalcraft and ColorCote really can make a difference. These brands often have top quality finishes that can handle even the worst weather. As well as this, you should be wary of coastal environments. If you live by the water, the salt in the air may affect your roof and cause it to wear down faster. Always consult a professional roofing supplier before committing to a new roof.
Asphalt and Fibreglass Shingles
Asphalt shingles are usually the most inexpensive and easy product to install, but that doesn’t make them long lasting. The average life expectancy of asphalt singles is only 20-40 years, depending on the manufacturer and local conditions.
Fibreglass shingles are a more expensive variety and you might get a longer life out of them. Some fibreglass shingles have been made to last up to 50 years.
Stone tile roofing systems are usually made of slate, clay, terracotta or concrete. Stone is a fine material to use for roofing, as it is not only aesthetically appealing, but also able to withstand strong winds and heavy rain.
Clay tiles can typically last about 40 to 60 years, but they are very heavy and not easy to install. This makes DIY work and repairs difficult and it may increase the costs of installation.
Flat roofs are often made of rubber, usually EPDM. This synthetic rubber roofing membrane is great for UV resistance and durability, but it is often very expensive.
The average lifespan of this roof is 40 to 50 years, although many manufacturer warranties only guarantee them for a life expectancy of 10 to 15 years.
