Flat Roof Installation

Alpha Building Group provides high-performance flat roofing solutions for commercial and residential properties, delivering robust waterproofing systems that stand the test of time. With extensive expertise in flat roof construction and refurbishment, our team manages every stage of the process – from site survey and system specification through to installation and ongoing maintenance.

We install a wide range of advanced flat roofing systems, each suited to specific project requirements. These include bituminous membrane systems, known for their exceptional durability, tensile strength, and resistance to thermal movement and foot traffic – ideal for both new builds and refurbishments. Where required, we can overlay existing systems to extend lifespan without full removal.

We also specialise in cold-applied liquid roofing, offering seamless, flame-free application – perfect for sensitive or complex roof areas. These systems are fully bonded, quick to install, and provide excellent resistance to standing water and weather extremes, making them ideal for detailed or irregular roof structures.

In addition, we offer single-ply roofing systems, valued for their lightweight construction, high thermal performance, and fast installation. These flame-free systems can be installed using adhesives, hot-air welding, or mechanical fixings depending on the project's demands. They are an excellent choice for clients seeking efficient, recyclable roofing with minimal environmental impact.

As certified installers for leading manufacturers, Alpha Building Group ensures all flat roofing systems are installed to the highest standards, delivering long-lasting, energy-efficient protection that meets both aesthetic and performance expectations.

Pitched Roof Installation

Pitched roofs remain the traditional and most visually prominent roofing solution for residential properties, offering excellent rainwater runoff and a longer lifespan than many alternatives. Alpha Building Group provides expert pitched roof installation for new builds and renovations, working with slate, tile, or composite materials to suit both architectural style and performance requirements. Our team ensures structural integrity, proper ventilation, and full compliance with building regulations. Whether it's a simple gable roof or a complex multi-angled structure, we ensure every pitched roof is built for strength, beauty, and long-term weather resistance.

Metal Roofing Services

Metal roofing systems offer a sleek, durable, and fire-resistant solution for both industrial and modern residential buildings. At Alpha Building Group, we supply and install high-quality standing seam, corrugated, and profiled metal roofing systems in aluminium, steel, or zinc finishes. These roofs are designed for exceptional longevity, with minimal maintenance and excellent resistance to corrosion and extreme weather. Ideal for commercial units, agricultural buildings, and contemporary home designs, our metal roofing services include full design consultation, thermal insulation, acoustic considerations, and custom flashing and trim details.

Roof Access & Protection Systems

Safe and secure roof access is essential for ongoing maintenance, inspections, and compliance with health and safety regulations. Alpha Building Group provides a range of roof access and fall protection systems tailored to both domestic and commercial properties. From permanent access ladders, walkways, and guardrails to fall arrest systems and edge protection, we ensure every installation meets regulatory standards. Whether you're a facilities manager or a homeowner, we can assess your requirements and deliver practical, compliant solutions to keep operatives and residents safe when working at height.

Exterior Cladding Services

Exterior cladding enhances the aesthetics, insulation, and weatherproofing of a building. Alpha Building Group offers full cladding services to both residential and commercial clients, using materials such as metal, fibre cement, composite panels, and timber. Our solutions are tailored to each project, improving building performance while transforming external appearances. From contemporary rainscreen systems to robust industrial cladding for warehouses and retail units, we manage everything from substrate preparation to final detailing. Our cladding installations are fully weather-sealed, thermally efficient, and built to last.

Rooflight Renewal

Rooflights are a key component in bringing natural light into interior spaces, but over time they can become damaged, discoloured, or inefficient. Alpha Building Group offers rooflight renewal services to upgrade existing installations or replace failing units with high-performance, modern alternatives. We supply and fit a wide range of rooflight types, including domes, lanterns, and flat glass systems – all compliant with current building standards. Whether part of a flat or pitched roof, our team ensures all renewals are leak-free, secure, and optimised for thermal performance and light transmission.

Environmental Roof Installation

Green and environmental roofs provide a sustainable, visually striking alternative to conventional roofing systems. At Alpha Building Group, we install eco-friendly roof solutions such as sedum green roofs, wildflower systems, and solar panel-integrated structures. These installations help regulate temperature, improve air quality, reduce stormwater runoff, and promote biodiversity. Suitable for both domestic and commercial applications, our environmental roof services are delivered with a focus on structural compatibility, drainage planning, and long-term maintenance support. We guide clients from concept through to final planting or PV connection.

Flat to Pitched Roof Conversions

Converting a flat roof to a pitched system can dramatically improve aesthetics, increase internal ceiling height, and solve ongoing water pooling or drainage issues. Alpha Building Group provides full flat-to-pitched roof conversion services, including structural design, planning support, and complete installation. Whether you're looking to modernise the look of your home or eliminate the maintenance challenges of a flat roof, our team will engineer and deliver a tailored solution that enhances both function and kerb appeal. We ensure minimal disruption throughout the build and deliver a finished product that's visually balanced and structurally sound.
