Q. Why should I choose GRP fibreglass flat roofing over a conventional felt roof?

GRP or Fibreglass flat roof coverings are far superior than felt. Why? 1-120140530_151950_Android_editThey have a vastly longer lifespan and are simply more durable. They can be both aesthetically pleasing and functional too. They can even be walked on.

Q. How expensive will my GRP fibreglass flat roof be?

There are many factors to be considered in calculating the cost of installing your fibreglass flat roof. Bottom line is that it will work out much cheaper than any conventional flat roofing material over its very long lifespan.

Q. How long will a GRP fibreglass flat roof last?

There are fibreglass roofs in existence today that were installed over 50 years ago. Yes really. With today’s advanced materials, a well-laid fibreglass roof installed by experienced professionals like Proplas will outlast just about any other roofing system. In fact it’s often recommended by architects as a ‘gold standard’ option for new builds to ensure a quality roof that lasts.

Q. What are the colour options available?

Because we have vast technical experience and industrial backup, we offer a full spectrum of colours for your fibreglass flat roof. You can even have custom colours to your own specification, multi colours and even patterns. The only limit is your imagination. Don’t forget that Phil, the owner of Proplas, is also a fibreglass sculptor so you can have something truly bespoke for your flat roof if you wish! Phil is happy to advise, should you need ideas or inspiration.

Q. How safe is grp fibreglass flat roofing?  Is it flame retardant, waterproof and can you walk on it?

Very, Yes, Yes and Yes. GRP fibreglass roofing is incredibly safe and very, very waterproof. The materials are cold-applied so there is never any danger from flames as used in other applications. Fire retardant is standard with the Premier System. Non-slip grit can be added to any system and fire retardant can be added to the Standard System, should it be required.

Q. What maintenance will my fibreglass flat roofing need? How to clean a fibreglass flat roof?

Fibreglass flat roofs need very little maintenance. We recommend periodic washing with warm soapy water and a soft brush to keep it looking nice and new. Simple.

Q. Can the fibreglass flat roofing be insulated?

Any amount of insulation can be installed if needed – thermal or acoustic.

Q. Will I get pools of water or puddles? What drainage system is needed?

Fibreglass flat roofing should have a ‘fall’ to a drain or gutter, preventing pooling.  We can always incorporate a water feature should you require it! Proplas owner, Phil, has had personal hands-on experience in the industry for 30 years, and has never had a roof fail to date.

Fibreglass flat roofing is easy to repair, if needed. We have a full fibreglass roofing repair service. We’re equally happy advising customers directly on how to do it themselves.
