Introduction
Why Choose Welted Aluminium?
Aluminium is lightweight, durable and naturally resistant to corrosion, ideal for the UK's demanding climate. Our approach uses traditional welting 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 welts aluminium on site so every junction remains watertight and built to last.
Key Benefits
Advantages of Welted Aluminium Roofing
Watertight Welted Joints
All seams and junctions are welted 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, welted 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 welted junctions and details

Maintenance
Caring for Your Aluminium Roof
Welted 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
- Inspect welted seams and joint sealants annually
Gentle Cleaning
- Wash with mild detergent and soft brush every 12-18 months
- Avoid abrasive cleaners or tools that damage the finish
Gutter Maintenance
- Clear gutters and downpipes regularly to prevent water backup
- Remove debris that could cause standing water
Professional Service
- Consider a professional inspection every 5 years
- Address any movement or damage promptly
Sustainability
Environmental Benefits
Aluminium combines long-life durability with exceptional recyclability. These are the core environmental advantages clients value most.
Responsible materials, reduced maintenance and long service life help aluminium outperform many roofing systems on environmental impact.
- Infinitely recyclable
- Low embodied carbon
- 50+ year lifespan
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 from raw materials.
Long Lifespan Reduces Waste
50+ years of service means fewer replacements and reduced material consumption over the building lifecycle.
No Toxic Runoff
Unlike some roofing materials, aluminium doesn't leach harmful chemicals into rainwater or surrounding ecosystems.

FAQs
Frequently Asked Questions
How long does a welted aluminium roof last?
With proper installation and minimal maintenance, welted 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 welted seams and mechanically formed joints. All external junctions are sealed by welting 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 welting, 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.
