Fibreglass Flat Roof Lifespan

This is where the term alligatoring comes from.

Fibreglass flat roof lifespan.

You will have to also take into consideration the environment the surface is exposed to the level of maintenance it receives over the years and the amount of foot traffic. Even though this is a normal thing within the lifespan of fibreglass roofs. Fibreglass roofs can last for 50 years. The result is the roof becomes to looking wrinkled and cracked like the skin of an alligator.

Compared to an average life expectancy of bitumen based materials the life expectancy of a fibreglass roof is far greater than other flat roof products making it a cheaper option on a year by year basis. In our experience a professionally applied fibreglass roof will last a lot longer than the 30 years. Most traditional flat roofs are made from either mineral felt or asphalt and will have a maximum life span of between ten and 15 years. For grp roofs this can reach up to 50 years well over the average flat roof.

The noise can be reduced by special expansion joints that can be added when the roof is being installed. It typically has a lifespan of 40 to 50 years although most manufacturer warranties only guarantee a lifespan of 10 to 15 years. Grp resin catalyst hardener fibreglass mating and a top coat resin are the essentials of a grp roofing system along with the fibreglass roof trims and flashing. Thermoplastic olefin membrane is another flat roof option made from.

In addition to these materials a grp shopping list also needs to include sealants and adhesives to bond trims and flashings along with rollers brushes and buckets. Unfortunately though they have a bad reputation due to their propensity to leak or become damaged through pooling water. However when it reaches that age it can lose its elasticity causing it to look cracked and wrinkled like the skin of an alligator hence the term. When a grp roof does reach this age it can lose its elasticity.

For one all roofs have a certain life expectancy.
