GRP Roofs

Flat roofs have long been a cause of concern in the UK, as it is UV rays that damage most flat roofs (rain just shows the symptoms of the damage caused by the sun) one might wonder how, in hot countries, there are so many successful flat roofs. We believe the main reason for flat roof failure in the UK is the fact that we experience many more temperature changes.

Midwest Roofing have tried many different flat roofing solutions, some more successful than others. Built-up felt systems rely on heat being applied to the roof either by using hot (melted) bitumen or torch-on felt. GRP requires no torch/heat.

The Solutions

FIBREGLASS Roof with 20 Year Materials & Workmanship Warranty: @ £65m2: 3 meters x 7 meters Garage /Kitchen roof from: £1,365 – 10 years Insurance Backed Guarantee as Standard.

New 18mm OSB3 boards is laid on the existing roof joists. Once the entire roof area is decked our skilled team will fix all the pre-formed trim detail to the new roof, each joint is carefully laminated with resin and a 450g mat bandage to provide additional structural strength at all joints and roof details.

Upon completion of the deck and trim details, the roof is laminated with a resin and a 600g mat glass fibre mat, not a 450g mat that many other companies will use. (If you have a terrace /balcony we recommend 600g mat x 2 giving you a 1200g mat glass fibre mat) The roof is finally sealed with a further coating of nonslip topcoat. The topcoat can be pigmented in several standard colours, although we recommend the standard light grey colour to diminish thermal gain. The topcoat will also stop any UV transmission into the body of the GRP layer.

GRP Roofs expected lifetime of up to 20 years, yet remains easy to remove and recycle at the end of its useful life. In addition, the thin design results in the minimal use of raw materials in manufacture and energy for transportation. It is UV resistant. Fibreglass roofs can be ideal for awkward situations or where a walking surface is required.

Midwest Roofing can install any type of fibreglass flat roofs, high-quality roofs which are fully guaranteed up to 20 years.
