Flat roofing installation
and repair

Why install a flat roof?

Flat roofs are known for their space saving, compact design and are very popular on modern minimalist architect-designed homes. They are also particularly well suited to smaller structures, such as extensions, porches, dormer roofs and garages.

Types of flat roof

Built-Up Felt

Built-up bituminous felt roofing

Our modern high performance built up felt roofing systems are the best systems available for a flat roof. They are ideal for both new build and refurbishment projects.

We have installed thousands of square metres of bituminous roofing over the past three decades to a whole range of buildings: from houses and garages to factories and schools. We only use approved contractor and market-leading products, which are incredibly robust and durable. Most of our installations come with a manufacturer’s warranty, which covers our workmanship and the materials used.

Glass Reinforced Plastic

GRP fibreglass roofing

GRP fibreglass has a high strength-to-weight ratio, which means that it can hold a lot of weight, making it an ideal choice for balconies and terraces.

These roofing systems are particularly aesthetically pleasing and can be installed with colour matching to any RAL colour for an excellent finish to perfectly match your building.The fact that you can choose the colour makes it an excellent and cost-effective replacement for decorative metal roofs, such as copper and lead. GRP fibreglass is very versatile and can also be installed onto pitched roofs.

Single Ply Roofing

Single Ply Roofing

Single ply roofing is a flat, synthetic polymer-based roofing material that provides one single layer of waterproofing to your flat roof.

Single ply roofing systems are most commonly found on large commercial flat roof areas, but architects often specify single ply roofing membranes on new build homes. We only install the highest quality approved contractor single ply roofing systems that our roofers have been trained to install. Our systems are aesthetically pleasing, robust, durable, low maintenance and come with a manufacturer’s warranty.

Insulated Flat Roofing

Insulated Flat Roof

A flat roof refurbishment is the perfect opportunity to improve the thermal efficiency of your property.

Insulated flat roofs offer great thermal performance in comparison with pitched roof profiles. We are accredited by the NFRC Roofing Competent Person Scheme, which means that we are able to issue you with a Building Regulations Certificate of Compliance when we install insulation to the required levels to your flat roof.

Green Roofing

Green Roofing

Green roofing systems provide a great opportunity to introduce an element of the natural surrounding to a building.

On some flat roofs, a green installation can even provide additional recreational space. A sedum roof covering is an increasingly popular choice for a green flat roof. These drought resistant plants, originally naive to rocky alpine outcrops, require very little soil and provide natural insulation.

Repair to pitched roofs following storm damage, chimney repairs, tile and slate replacements. Full repair or refurbishment of your tiled pitched roof.
