A GRP roof is possibly one of the best and most reliable ways to weatherproof flat, barrel-vaulted or pitched roofs out there on the market. As it’s low maintenance, it’s easy to manage and the quality materials make it one of the best roofing methods available. Fibreglass roofing includes wetting out the layers of glass mat on the roof of a building and when this has been cured, your roof should have strength. It can also give you a waterproof barrier across the surface which is perfect for a flat roof.
There is a list of materials that are required to fibreglass a flat roof, and these include:
- Fibreglass matting.
- Ancillary tools
- Roofing resin
- GRP roofing trim
- Roofing topcoat
When the resin has cured, you can apply a topcoat which acts as a tack-free sealant securing the fibreglass underneath. The topcoat adds colour to the roof, and you should ensure that it’s non-slip in case you need to walk on your roof after the application.
So, what are the advantages?
Unlike most materials for roofing, fibreglass doesn’t rot or smell and it doesn’t gather moss. It’s easy to clean, too, which is handy for those who prefer their gutter and roof cleans to be easy. There are many other benefits of a GRP roof, and these include:
- Most of these roof options have a life of 20 years from correct installation.
- There is no complex machinery required to install a GRP roof, and a lot of the time, this kind of roof doesn’t require any heat equipment. This reduces on-site accidents for installers, making for a safer roof option.
- There are a variety of roof trims that you can select from that suit the roof build. You can easily cut these to the shape of the roof itself and this makes a GRP roof a very flexible option.
- As the fibreglass roof has no seams, it’s entirely waterproof. GRP was originally used for boats and yachts – and it still is today. This should give you the confidence that it can withstand horrendous rains and an aggressive weather environment. Consistent waterproofing is so important, as you won’t end up invalidating your insurance or losing your belongings to water damage.
- The topcoat is also waterproof, which makes it resistant to weathering. Rain isn’t the only worry; the heat of the sun – which can warp some materials – won’t affect your GRP roof in the same way.
- The repairs and maintenance of a GRP roof mean that it’s easy to keep clean. A simple brush or hose down should do the job to keep it completely clean.
There are a lot of options out there for your flat roof and you may have heard felt and rubber are your material options as they are widely used in both commercial and residential buildings. However, doing your research on the durability of GRP roofing could be everything that you need to make the switch. It could be the best decision that you make this year.
