Flat Roofing Systems We Provide

Single Ply Roofs Edinburgh

One of the most popular options for modern builds and refurbishments is the single ply roof system. At Valtor Roofing, we supply and install EPDM, TPO, and PVC membranes, which are lightweight, flexible, and highly durable.

The benefits of single ply roofs in Edinburgh include:

  • Minimal seams for maximum waterproofing
  • Excellent energy efficiency and thermal performance
  • Lightweight installation ideal for new builds and roof overlays
  • Fast application with minimal disruption
  • This system is particularly well-suited to commercial properties, extensions, and larger residential projects where cost-effectiveness, reliability, and performance are critical.

GRP (Fibreglass) Flat Roofs

GRP, or fibreglass roofing, has become a highly popular option for both domestic and commercial clients. The system is applied in layers, forming a tough, seamless finish that is watertight and resistant to weathering.
We often recommend GRP for extensions, balconies, and roof terraces because it can be finished with non-slip coatings and is highly resistant to foot traffic. As flat roofing contractors, we also value GRP for its longevity, often lasting 30+ years with minimal maintenance.

Traditional Felt and Lead Roofing

Flat roofs in historic parts of Edinburgh often require a more traditional approach. Our team has the skills to work with felt and lead flat roofs, ensuring that repairs and replacements remain sympathetic to the character of heritage buildings.
These systems are still widely used across the city. Felt offers a cost-effective solution for garages, outhouses, and smaller roofs, while lead is highly durable and perfectly suited to conservation projects.

Liquid-Applied Flat Roofing Systems

Where complex detailing, awkward roof shapes, or flame-free application is required, liquid-applied membranes provide the perfect solution. These systems are cold-applied, forming a seamless and flexible waterproof barrier that bonds to most surfaces.
They are particularly effective for refurbishments or projects where speed is critical. Many of our commercial and industrial clients in Edinburgh choose liquid systems for their adaptability and long-term protection.

Why a Tailored Approach Matters for Flat Roofing in Edinburgh

The weather in Edinburgh can be unforgiving. Heavy rain, high winds, and regular freeze-thaw cycles all put additional strain on a flat roof. A one-size-fits-all approach will not work.
That’s why we assess each property individually, considering drainage, insulation, materials, and detailing to ensure the system is fit for purpose and built to last. For example, a modern extension may benefit most from single ply or GRP, while a listed tenement in the Old Town may require a traditional felt or lead system. By tailoring the roofing system to your property, we ensure your investment is protected and your roof delivers performance for decades to come.

Absolutely. Many homes across the city already use flat roofs for extensions, tenements, and garages. With the right system, flat roofs provide excellent protection and can even be adapted for green roofs, solar panels, or roof terraces.

Costs vary depending on the size, materials, and complexity of the project. Felt and single ply systems are generally more affordable, while GRP and liquid-applied systems provide premium performance. We always provide clear, tailored quotes after a full inspection.
