London & Surrey’s Professional Cold Flat Roof Contractors

Are you looking for a cold roof roofing contractor? At Asgard Roofing, our highly experienced roofing contractors are here to help you with all your roofing and building needs. With over two decades of experience working across domestic and commercial properties in Surrey and London, we know how to get the best cold roof solutions for your roof structure.

We can install thorough cold roof insulation installation, helping you quickly and efficiently protect your property. As one of the most cost-effective methods of installing thermal insulation to your existing roof joists and pitched roof rafters, cold roofs remain one of the most popular types of our installation services.

What is a Cold Roof?

Cold flat roof construction is widespread and involves insulation boards being placed between and below the roof covering. This is typically used during a refurbishment of older joisted roofs that do not have a current insulation layer. As the materials are placed above the plasterboard, it can mean that you do not need to replace the waterproofing membrane on the existing roof decking or raise the roofline.

As one of the leading providers of pitched and flat roof constructions in Merton, Wandsworth and across South London, our dedicated team are here to help you transform your property, so get in touch today to find out more.

Cold VS Warm Roofs

Both options are our top-rated flat roof services for property owners across Surrey and London, providing various benefits. A warm roof (warm roof construction)is a straightforward thermal bridging install that puts insulation boards on top of the roof, with a vapour control layer before the flat roofs waterproofing layer is added.

On the other hand, cold roofs have rigid insulation placed between the structural supports at the ceiling level. This ensures the roof void between the roofs covering and the interior ceiling retains warm air below the cold surface, which is particularly beneficial in winter.

We install Single-ply waterproofing and many flat roofs systems

we use the following systems for general flat roofs, cold roof constructions and warm roof constructions

  • EPDM roofing system
  • GRP Fibreglass system
  • Torch on felt flat roof system
  • Liquid waterproofing system
  • Slate lead roofs
  • Redland 49 tile roofs
  • Clay tile roofs

Warm Roof Construction

Our flat roofing service continues beyond cold roof construction. We also offer the installation of warm roofs, which can significantly improve the thermal performance of your building.

Heat is retained within the building with a warm flat roof rather than lost to the cold outside air. This can lead to reduced energy bills, improved comfort levels, and a more sustainable building overall.

Asgard Roofing – the local cold roof roofing contractors you can Trust

We pride ourselves on our expert flat roof installation and the quality of our work, which is why we strive to exceed your expectations with every project. Our roofing services and installations come with a standard ten-year, insurance-backed guarantee designed to give you complete peace of mind that you are protected should any problems arise.

Why must a gap between the insulation and the roof deck be provided?

The roof has a cold bridging, so a higher moisture build-up exists. To prevent issues like that causing problems such as dampness and mould, there must be adequate roof void ventilation to allow this moisture to escape.

This is the complete opposite of what is required for a warm roof type of roof. Our expert flat roofing team will be able to provide adequate ventilation, allowing your roof to thoroughly remove moist air and ensuring your roof can last for as long as possible.”
