Fibreglass Flat Roofing

Yes, a correctly installed fibreglass flat roof will last 30+ years.

Approximately the same as other flat roofing systems. Since 1976, we’ve found fibreglass roofs to out-last rubber and other sheeted membranes, so the lifetime cost is cheaper versus less durable flat roofing systems.

In short, it is much more durable – it is resistant to tearing so tolerates foot traffic, is extremely hard-wearing and it is puncture resistant.

This is almost always down to poor installation quality. Applicators that are not properly trained or do not install a fibreglass system correctly cause flat roofing systems to leak.

Look for: 1) a long, successful track record, 2) insurance-backed guarantees, 3) accreditations and 4) a good technical understanding.

Built GRP is an independently tested fibreglass roofing system. Demonstrating superior mechanical properties and excellent waterproofing, it offers extensive guarantees and an approved contractors list. There are two tyes: S600 (single layer laminate) for standard applications and the D600 (dual layer) for more demanding applications expecting foot traffic.

Yes, fibreglass has a high strength-to-weight ratio, long-term durability and waterproofing potential as well as excellent abrasion resistance and impact resistance. Unlike other membranes, it can tolerate foot traffic. It is also versatile, meaning it can be applied to a range of substrates, from timber to concrete and plywood.

Yes, some fibreglass composites exhibit very high strength-to-weight and modulus-to-weight ratios comparable to some metallic materials.
