How to Calculate Your m²/ft²?

How to Calculate Your m²/ft²?

It’s actually very easy to calculate how many square meters or foot an area is, whether it is a simple rectangle or more complex shape. When dealing with a simple rectangle, just multiply the length by the width for your total square meterage or footage. If you’re dealing with a more complex shape, treat each area as a rectangle and perform the same calculation. Then combine the square meterage or footage of each area for to get the total area.

Common Questions

What is GRP Fibreglass Roofing?

GRP or Glass Reinforced Polyester, also known as Fibreglass is an incredibly popular flat roofing material. It is a composite material manufactured by combining sturdy plastic with fine glass fibres to create an incredibly durable, long-lasting roofing material. GRP Fibreglass Roofing is used by tradespeople and homeowners right across Britain for a wide variety of flat roofing projects.

How Much Does A Fibreglass Flat Roof Cost?

The cost of a fibreglass flat roof depends on a number of factors. Firstly, will you be undertaking the project yourself or hiring a professional? Although GRP is a highly cost-effective roofing material, if consulting a qualified tradesperson this will naturally increase project costs. For a new fibreglass flat roof, you can expect to pay around £90 per square metre for materials, not including OSB boarding.

Do GRP Roofs Crack?

Yes, GRP roofs can often crack due to a number of reasons. GRP roofing systems cannot accommodate the same amount of thermal movement or flexibility that EPDM rubber roofing offers, and so if poorly installed then a GRP roof can be susceptible to cracking.

How Long Does a Fibreglass Roof Last?

You can expect a fibreglass roof to last for up to 30 years, or even beyond, provided it has been installed correctly and received proper care and maintenance throughout its lifetime. This makes GRP roofing kits an incredibly cost-effective roofing solution long-term, particularly when compared to the poor durability of traditional felt roofs.

Is A Fibreglass Roof Better than Felt?

Fibreglass roofing has many advantages over felt. Firstly, as a fibreglass roof kit will produce a flat roof that is entirely without seams, it will have far fewer weak points for water ingress and other issues that commonly plague felt roofing. GRP is also much more durable and resistant to weather damage and impacts and can be expected to last many years longer than felt. The only drawback is that fibreglass costs considerably more than felt, however many homeowners feel that these benefits make the added cost more than worth it.
