Introduction
Why Choose Zinc for Your Roof?
Zinc roofing represents the pinnacle of architectural metal roofing in the UK. Renowned for its distinctive aesthetic appeal and exceptional longevity, zinc has been a preferred choice for prestigious buildings across Europe for over 150 years. Its natural self-healing patina and remarkable 100+ year lifespan make it one of the most sustainable roofing materials available.
Whether you're working on a contemporary new build, a period property restoration, or a modern extension, zinc roofing delivers unparalleled performance in the British climate while developing a beautiful, protective patina that evolves over time.
Key Benefits
Advantages of Zinc Roofing
100+ Year Lifespan
Titanium zinc roofing can last well over a century with minimal maintenance, making it one of the longest-lasting roofing materials available
Self-Healing Patina
Develops a protective zinc carbonate layer that self-heals minor scratches and protects against corrosion throughout its lifetime
Fully Sustainable
100% recyclable with no loss of quality. Zinc is a naturally occurring element that requires minimal processing compared to other metals
Beautiful Aesthetics
Distinctive blue-grey patina develops naturally over 2-5 years, creating a unique and sophisticated appearance that ages gracefully

Installation Process
Professional Zinc Installation
Zinc requires specialist installation techniques for optimal performance
Substrate & Ventilation
Install timber boarding or metal deck with ventilation gap. Zinc must not contact cement, copper, or steel directly to prevent galvanic corrosion.
Underlay Installation
Apply approved underlay membrane. Ensure complete weatherproofing before zinc installation. Install thermal insulation as required.
Panel Fabrication
Cut and fold zinc sheets to precise measurements. All folds must allow for thermal expansion. Maximum panel widths typically 650mm.
Fixing & Sealing
Install using formed joints that allow movement. Form watertight seams using traditional hand tools. Complete with zinc flashings and trims.

Pricing Guide
Zinc Roofing Costs in the UK
Zinc is a premium roofing material. Prices reflect specialist installation requirements and material quality. Typical 2024 costs:
£120 - £180
Per m² - Standing Seam
£140 - £200
Per m² - Batten Roll
£160 - £220
Per m² - Flat Lock/Cladding
Cost Considerations:
- Pre-weathered finishes (ANTHRA-ZINC, PIGMENTO) add 15-25% to material costs
- Complex roof geometries increase labour costs significantly
- Heritage/conservation projects may require specialist approval
- Zinc accessories (gutters, downpipes, flashings) typically £80-150 per metre
- Consider whole-life costs - zinc requires minimal maintenance over 100+ years
Natural Beauty
Understanding Zinc Patina Development
One of zinc's most distinctive characteristics is its natural patina development. This protective layer not only enhances the aesthetic but also provides long-term corrosion protection.
Initial Installation
Bright metallic silver-grey appearance (mill finish) or pre-weathered finish if specified.
Early Patination
Surface begins to dull and develop subtle blue-grey tones as zinc carbonate forms.
Developing Patina
Distinctive blue-grey patina becomes established across most of the surface.
Mature Patina
Full protective patina layer. Self-healing properties continue throughout lifespan.
Note: Patina development varies by location, exposure, and climate. Urban areas may develop patina faster due to atmospheric conditions. Pre-patinated finishes (QUARTZ-ZINC, ANTHRA-ZINC) provide immediate consistent appearance.
Maintenance
Caring for Your Zinc Roof
Zinc roofing requires minimal maintenance due to its self-protecting patina. However, following these simple guidelines will ensure optimal performance:
- Annual Visual Inspection: Check for debris accumulation, leaf blockages in valleys and gutters
- No Aggressive Cleaning: Never use acidic or alkaline cleaners - they damage the protective patina
- Debris Removal: Clear leaves and organic matter to prevent staining and water retention
- Gutter Maintenance: Keep gutters clear - zinc gutters should last as long as the roof
- Avoid Contact: Prevent contact with copper, steel, or lead which can cause galvanic corrosion
- Professional Inspection: Recommend specialist inspection every 10-15 years
- Repairs: Minor repairs can be made by welding or soldering new zinc sections
Sustainability
Environmental Benefits of Zinc
- 100% Recyclable: Zinc can be recycled infinitely without degradation - approximately 90% of zinc is recycled at end of life
- Natural Material: Zinc is the 24th most abundant element in the Earth's crust - a naturally occurring resource
- Low Embodied Energy: Zinc production requires less energy than stainless steel or copper per tonne
- Century Lifespan: 100+ year expected life means minimal replacements over building lifetime
- No Toxic Runoff: Unlike copper, zinc runoff is not harmful to aquatic ecosystems in typical concentrations
- Self-Protecting: No painting or coating required throughout entire lifespan - zero VOC emissions
- Thermal Performance: Reflects solar radiation reducing cooling loads in summer months

FAQs
Frequently Asked Questions
How long does a zinc roof last?
Titanium zinc roofing has a proven lifespan exceeding 100 years. Many original zinc roofs installed in Paris in the 1860s remain in excellent condition today. Manufacturers typically offer 30-40 year warranties.
Will zinc patina look different on different parts of my roof?
Yes, patina development varies by exposure. Areas with more water runoff or south-facing aspects may patinate faster. This natural variation is part of zinc's character. Pre-weathered finishes provide uniform appearance from installation.
Can zinc roofing be repaired if damaged?
Yes, zinc can be easily repaired by specialist roofers. Damaged sections can be cut out and new zinc welded or soldered in place. The patina will develop on repairs over time to match the surrounding area.
Is zinc suitable for curved or complex roofs?
Absolutely. Zinc's malleability makes it ideal for complex geometries, curves, domes, and bespoke architectural features. Batten roll systems are particularly suited to curved applications.
Do I need specialist installation for zinc?
Yes. Zinc requires trained installers familiar with material properties, thermal movement allowances, and proper seaming techniques. Always use approved contractors certified by zinc manufacturers.
How is welded zinc different from screw-fixed metal roofing?
Traditional zinc roofs are fully welted, soldered and seamed on site so there are no exposed screws or rivets to fail. The welded approach creates a continuous skin that copes with thermal movement on complex buildings, unlike modern screw-fixed sheet systems that rely on sealants or gaskets.
