How Long Do Fibreglass Roofs Last?

Fibreglass roof installation is normally laid in either one or two layers, usually with a joint-less finish. Fibreglass roofs can be made to any colour. Most fibreglass roofs are guaranteed for 25 years but can last much, much longer if well looked after; cleaned and maintained. Fibreglass is expensive due to material costs, and although it is not as flexible as rubber it is incredibly resistant to damage and repairs are very easy and almost un-seen. Fibreglass roof installations are a great choice as they are extremely weatherproof and at little risk of leaking or developing frost damage (Fibreglass is also used on the hulls of some boats to give you an idea of strength). If you can stretch to the extra cost then it is well worth the money in terms of both durability and aesthetics.

How many years do fibreglass flat roofs last?

Most traditional roofs that are made from either asphalt or mineral felt will have a maximum life expectancy of between 10 to 15 years. Though they have quite a poor reputation in the industry due to their likelihood to leak or get water damage through ‘pooling’ – the unwanted gathering of water which accelerates the deterioration of many materials which include roofing asphalt.

The silver lining – if you keep your fibreglass roof clean and well maintained, you could have a fibreglass roof that lasts you between 20 to 30 years, before it needs replaced. Your fibreglass roof could last even longer before you need another fibreglass roof installation due to the introduction of plastic and rubber materials.

How many fibreglass flat roof installations will I need?

Depending on how you are at your property, you may need to have a maximum of two to three flat roof installations during your lifetime.

You do have other options for flat roof materials. These include EDPM and TPO roofing options. EDPM and TPO are types of rubber which tend to have a longer lifespan that the traditional materials, but Fibreglass is a much harder wearing material and is a preferred and smarter option.

If your property consists of either a full or partial flat roof then you will be well aware of the need for continued maintenance in order to prolong its lifetime, as well as the need eventually to replace the covering over time.

There are many ways to clean your Fibreglass flat roof after getting rid of all the leaves, debris and water. The simplest way to clean your fibreglass flat roof is with a yard brush and some hot soapy water. For less labour-intensive work, you can use a pressure washer or when you have a flat roof with a non-slip surface. You also want to ensure that pooling isn’t happening and that your fibreglass roof is not a water trap.

Materials have developed and advanced over time, and you will need to look at the best option for you: Fibreglass, TPO, EDPM, Felt, Copper, and Zinc, and more.
