Introduction
Why Choose Welded Aluminium?
Aluminium is lightweight, durable and naturally resistant to corrosion, ideal for the UK's demanding climate. Our approach uses traditional welding and seaming techniques to create fully watertight joints without exposed screws, bolts or fasteners.
Whether restoring a listed property, fitting a bespoke roof on a new home, or supplying engineered metalwork for large commercial or infrastructure projects, our team fabricates and welds aluminium on site so every junction remains watertight and built to last.
Key Benefits
Advantages of Welded Aluminium Roofing
Watertight Welded Joints
All seams and junctions are welded or mechanically formed, no exposed screws or bolts. Each joint is designed for long-term durability and weather protection.
Weather Resistant
Naturally resistant to corrosion and oxidation. Perfect for the UK's wet climate with no rust or degradation over time when properly finished.
Lightweight & Strong
Approximately one-third the weight of steel, reducing structural load while maintaining excellent strength and allowing installation on varied building types.
50+ Year Lifespan
With proper installation and minimal maintenance, welded aluminium roofing can deliver 50+ years of service, offering excellent long-term value.
System Types
Traditional Aluminium Roofing Methods
Standing Seam Roofing
Hand-folded and mechanically seamed vertical ribs create distinctive lines and excellent water shedding. Seams are formed without exposed fasteners.
- Fully welded junctions and details
- No exposed screws or bolts
- Allows controlled thermal movement
- Suitable for low pitch roofs
Batten Roll & Heritage Detailing
Traditional batten roll construction with hand-crafted aluminium cappings. Replicates heritage aesthetics while delivering modern durability and lightweight performance.
- Hand-formed cappings
- Welded hip and ridge junctions
- Suitable for curved and complex roofs
- Conservation area and listed building friendly
Bespoke Welded Metalwork
Custom-fabricated aluminium assemblies including welded trays, architectural flashings, copings and specialist details made to project tolerances.
- Fully welded fabrications
- Hand-formed complex profiles
- Built for long-life, maintenance-free service
- Available finishes: mill, PVDF, bespoke powder-coat
Installation Process
How We Install Aluminium Roofing
A professional installation process ensuring optimal performance and longevity with no exposed fasteners
Survey & Specification
Detailed site survey and material selection. We prepare drawings reflecting your project requirements and traditional welding/seaming methods.
Workshop & On-site Fabrication
Fabrication in our workshop and on-site forming as required. Welding, mechanical seaming and folding techniques are used to form watertight joints.
Installation & Sealing
Skilled installers position and secure assemblies using formed joints and welding. All junctions are welded or mechanically formed, with no exposed screws visible.
Quality Finish & Handover
Final inspection, flashings and trims completed, and all weatherproofing sealed. Client sign-off and provision of maintenance advice and project guarantees.

Maintenance
Caring for Your Aluminium Roof
Welded aluminium roofing is low-maintenance if properly detailed. Follow these guidelines to preserve long-term performance:
- Annual Inspection: Check for debris accumulation in valleys and gutters
- Gentle Cleaning: Wash with mild detergent and soft brush every 12–18 months
- Gutter Maintenance: Clear gutters and downpipes regularly to prevent water backup
- Weld & Sealant Checks: Inspect welded seams and joint sealants annually for any movement or damage
- Professional Service: Consider a professional inspection every 5 years
Sustainability
Environmental Benefits
- Infinitely Recyclable: Aluminium can be recycled repeatedly without quality loss, 75% of all aluminium ever produced is still in use today
- Energy Efficient Recycling: Recycling aluminium uses only 5% of the energy required to produce new metal
- Long Lifespan Reduces Waste: 50+ years of service means fewer replacements and reduced material consumption
- No Toxic Runoff: Unlike some roofing materials, aluminium doesn't leach harmful chemicals into rainwater

FAQs
Frequently Asked Questions
How long does a welded aluminium roof last?
With proper installation and minimal maintenance, welded aluminium roofing can last 50+ years in the UK climate. Many installations come with 20–30 year warranties.
Do you use screws or bolts?
No. Our roofing uses welded seams and mechanically formed joints. All external junctions are sealed by welding or seaming, with no exposed fasteners.
Can you work on listed or heritage buildings?
Yes. We specialise in conservation-sensitive work and deliver like-for-like replacements using traditional detailing and materials approved by conservation officers.
What about large commercial or infrastructure projects?
We deliver engineered metalwork for large structural projects including tunnels, utilities, transport infrastructure and major buildings. This requires full design co-ordination, workshop and on-site welding, and specialist installation, contact us for a detailed brief.
How do I get a quote?
Contact us to arrange a site survey. We provide detailed specifications, drawings and fixed quotations for residential, heritage and commercial projects.
What finish options are available?
Mill finish (natural silver), powder coating (RAL range) and PVDF coating (premium UV resistance). All finishes are selected for durability and aesthetic match to your project.
