GRP flat roofing is where a fiberglass roof has been installed, laid, and fitted properly. They last for a long time, usually for about thirty years, and throughout there will not be much noticeable damage to them over this time period. For the best results, they should be put in when the weather conditions are dry.
Resin and a top coat are needed for these roofs. Resin is a hydrocarbon secretion that acts as an adhesive and varnish. Resin is a material that will be used throughout the process of installing this roof. Top coats can be applied like a paint or a spray. They are what makes roofs resistant to water and keep the amount of ultra violet rays hitting it stable. These materials are the most important components of this type of roofing.
Top coats are also referred to as top seal. This is laid when wet and is made of a cold solution of unsaturated polyester resin. A strand mat provides reinforcement along with emulsion. It is cured with a peroxide catalyst to ensure that it completely bonds. It is finished with a polyester that is pigmented.
Bandaging of the joints of the boards and trims must be done. This lessens the risk of getting cracks and other damage. The bandages are consolidated and made of glass. Only a small amount of an adhesive, resin to be specific, is needed to adhere it.
Laminating is also important. This can be done after bandaging or before it. Longer runs of laminate are to be done in cooler temperatures while shorter ones should be done in warmer to hot temperatures. These also are adhered by the use of resin.
