GRP Flat Roofing

Over the years many good alternative systems have become available for flat roof replacement and a GRP Flat fibreglass roofing system is what is now generally recommended for use on domestic properties.  It is also ideal for balconies as it can cope with a lot of regular foot traffic.
Traditionally, domestic flat roofs are usually covered with bitumen felt and have been for many years with some stone chippings or gravel to help protect the felt from the sun damage. This method may look good at first but you soon hear complaints that the gravel fills the gutter and gives moss the ideal conditions in which to grow because the gravel retains the water. As the years go by the hot sun and cold weather makes the felt brittle and that makes it harder for the material to cope with the expansion and contraction that takes place on a roof. Slowly the material begins to crack and leaks start to form.
Sometimes these leaks will stay hidden for a long period of time whilst the supporting chipboard acts like a sponge by soaking up the water before drying out again, slowly causing structural damage to the roof timbers.
