Following on from our last blog on felt flat roof replacement, we thought it would make sense to move on to a brief overview of GRP flat roofing replacement.

GRP flat roofs (more commonly known as Fibreglass flat roofs) have become increasingly popular in the roofing world over the past 10 years. This is in no small part due to the fact most will be covered with a manufacturer guarantee of around 20 years and are expected to last around 10 years after that.

One of the other reasons for their increasing popularity is the fact that if they are installed correctly they will be very resistant to leaks. However if leaks do occur you will often find that the majority of the time it is due to errors in the original installation (laying a GRP roof is more challenging than many people anticipate) rather than the GRP roof reaching the end of its anticipated lifespan.

Unfortunately finding the cause of a leak in this type of roof can be a bit of a challenge, this is mainly due to the seamless construction of GRP roofing, but once the area of the leak is identified it is a very straightforward repair in most cases.
However if these small repairs do not fix the leak its often best to consider replacing the entire roof, as it is likely that the main cause will be an installation error as mentioned earlier such as if the boards used were not completely dry at the time of installation (in this situation the only option would be an entire roof replacement).
