Just wanted to know how long it would take to lay a fibreglass roof, we have a 15 square metre garage roof that needs to be done and we are getting roofers quoting us 3 days to complete the job.

A typical GRP roof installation of up to 20 square metres can be installed by a team of two contractors within a day. This would involve stripping the existing roof, laying fresh decking and applying the new system.

The weather is one of the main problems for holding up a GRP roofing job but a professional contractor would always prepare for that scenario and plan an installation around a block of good weather.

The amount of time you have been quoted there seems a bit excessive for the square metres you have to cover and would recommend you get a second opinion either from us or another GRP roofing contractor.
