In the UK we have a large variety of roofing materials and at Trilogy we use the vast majority. They range from:
Pan tiles – Pan tiles are an interlocking system which lap over just one course, creating a characterful roofscape. These can be with a profiled shape or they can be a flat tile and are traditionally made from Clay but Moreso Concrete in modern times.
Slate – whether it be natural or cement fibre, we deliver a smart, lightweight finish with exceptional durability, longevity, fire resistance, and low maintenance.
Plain tiles – Plain roof tiles are small, rectangular tiles typically made of concrete or clay, widely used in the UK for their traditional appearance. They can be made from either clay or concrete and can be used not only on pitched roofs, but on vertical faces of dormers and cladding.
Britmet - Britmet Lightweight Roofing is the UK's largest manufacturer of lightweight metal roofing systems and synthetic slate tiles, offering durable and cost-effective alternatives to traditional roofing materials. Their products are known for their ease and speed of installation, low weight (around 1/7th the weight of concrete tiles), and suitability for low-pitch roofs.
Tiled Roofs
Tiled roofs are a popular choice for homes and businesses due to their durability, weather resistance, and timeless appeal. Available in a wide range of materials, colours, and styles, they provide excellent protection against rain, wind, snow, and frost, while adding character and value to any property. With minimal maintenance required, they’re a long-lasting and cost-effective roofing solution.
Slate Roofs
Slate roofs are elegant, long-lasting, and highly resilient, making them ideal for both traditional and modern properties. Each slate tile is unique, offering a classic and refined appearance. Slate naturally withstands harsh weather, requires minimal maintenance, and can last over a century, making it a premium, eco-friendly, and reliable roofing option.
Flat Roofs
Flat roofs are a practical and versatile roofing solution, especially for modern homes and commercial buildings. They are easier to install and maintain, offer extra usable space for terraces or roof gardens, and can be constructed with durable materials such as rubber, asphalt, or PVC. Flat roofs provide effective weather protection when properly installed and maintained.
Flat Roofing Systems
Flat roofing systems provide a structurally efficient and cost-effective solution for residential, commercial, and industrial buildings. Commonly specified for extensions, garages, apartment blocks, and commercial units, flat roofs are designed with a slight fall to ensure effective rainwater drainage and long-term weather resistance.
At Trilogy Group Ltd, we design, install, repair, and maintain flat roofing systems in accordance with current building regulations and manufacturer specifications.
