Zinc has become one of the most popular choices for roofing in recent years. Its sleek, modern finish, outstanding durability, and eco-friendly credentials make it a strong contender for both residential and commercial projects. But while the material itself is excellent, the success of any zinc roof ultimately depends on the contractor you choose to install it.
Zinc roofing requires specialist knowledge, precision workmanship, and a solid understanding of building regulations. Choosing the wrong contractor can lead to poor installation, costly repairs, and a roof that falls short of its true potential.
This guide will walk you through everything you need to know about selecting the right zinc roofing contractors, so you can invest in your property with confidence.
Why Zinc Roofing Is Worth the Investment
Before we dive into selecting contractors, it’s worth briefly touching on why zinc roofing has grown in popularity across the UK.
Longevity: With proper installation, zinc roofs can last 80–100 years.
Low Maintenance: Zinc develops a protective patina that naturally resists corrosion.
Sustainability: Fully recyclable and requiring less energy to produce than many alternatives.
Versatility: Ideal for both traditional pitched roofs and contemporary designs.
These benefits mean zinc roofing isn’t just about aesthetics – it’s also about value, durability, and environmental responsibility. But all these advantages rely on the quality of the installation, which is where your contractor comes in.

Step 1: Look for Proven Experience
Zinc is not a material that every roofer can handle. Its installation requires specific training and a deep understanding of how zinc behaves over time.
Check Past Projects: Ask potential contractors to provide examples of completed zinc roofing installations.
Industry Experience: Look for companies with several years of dedicated experience in metal roofing.
Specialist Knowledge: Zinc installation differs from lead, copper, or steel. Ensure your contractor has expertise in this material specifically.
An experienced contractor will understand how to detail seams, joints, and fixings correctly – critical factors that affect the roof’s lifespan.
Step 2: Verify Accreditations and Training
Roofing is a trade where accreditations matter. They serve as reassurance that the contractor follows best practices and industry standards.
Manufacturer Training: Many zinc producers (such as VMZINC) offer training programmes for contractors. Check if your roofer is certified.
Industry Bodies: Look for memberships with recognisedorganisations like the NFRC (National Federation of Roofing Contractors).
Health and Safety: Verify that contractors hold CSCS cards, along with IPAF or PASMA for access equipment if required.
These accreditations not only guarantee competence but also demonstrate professionalism and commitment to quality.
Step 3: Review Reputation and Testimonials
A contractor’s reputation often speaks louder than their sales pitch.
Customer Reviews: Check online platforms, Google reviews, and testimonials on the company’s website.
Word of Mouth: Personal recommendations from neighbours, architects, or local builders are invaluable.
Case Studies: Reputable companies will showcase case studies highlighting their workmanship and problem-solving ability.
Look for consistency – if a contractor is repeatedly praised for professionalism, timeliness, and quality, they’re likely a reliable choice.
Step 4: Assess Communication and Professionalism
A contractor’s approach during the initial stages will give you a sense of how they’ll manage the project.
Clear Quotations: Expect detailed quotes outlining materials, labour, timelines, and any potential extras.
Transparency: Reliable contractors explain what’s included and highlight any exclusions upfront.
Responsiveness: If they’re slow to reply or vague in their communication, that could be a red flag.
Roofing projects are significant investments, so you need a contractor who keeps you informed at every stage.
Step 5: Understand Warranties and Guarantees
A high-quality zinc roof should last decades, but you’ll want to ensure you’re covered just in case.
Workmanship Guarantees: Contractors should provide a warranty covering the installation work.
Manufacturer Warranties: Many zinc suppliers back their materials with guarantees, often lasting 30+ years.
Insurance: Confirm that your contractor carries public liability and professional indemnity insurance.
These protections safeguard your investment and offer peace of mind.
Step 6: Evaluate Design and Detailing Expertise
Zinc roofing isn’t just about laying sheets – it’s about precision detailing that ensures long-term performance and striking aesthetics.
Seam Types: Contractors should advise on whether standing seam, flat lock, or other systems suit your project.
Integration: Look at how they plan to integrate zinc with other materials (stone, brick, timber, etc.).
Bespoke Solutions: The best contractors can adapt zinc to complex roof shapes or unique architectural requirements.
A roofer who demonstrates design understanding as well as technical skill is far more likely to deliver an exceptional result.
Step 7: Compare Value, Not Just Cost
It’s tempting to go with the lowest quote, but with zinc roofing, value is about far more than price.
Quality of Materials: Ensure they’re using zinc from reputable suppliers.
Workmanship Standards: Cheap labour often leads to costly future repairs.
Overall Package: Factor in warranties, project management, and aftercare.
Choosing a contractor solely on cost can be a false economy. Instead, look at the overall value they provide.
Step 8: Ask the Right Questions
When shortlisting contractors, don’t be afraid to ask questions such as:
- How many zinc roofing projects have you completed?
- Are you trained or approved by zinc manufacturers?
- Can I see examples of your work?
- What warranties do you offer on both materials and workmanship?
- How will you ensure the roof meets current building regulations?
A professional contractor will welcome these questions and answer them confidently.
Step 9: Consider Aftercare and Maintenance Support
Even though zinc roofs are low-maintenance, you may still need occasional inspections. A reliable contractor will:
- Offer guidance on routine checks.
- Provide aftercare services or maintenance packages.
- Be available for advice long after installation.
This long-term support sets the best contractors apart from those only interested in one-off jobs.
Final Thoughts – Choosing With Confidence
Zinc roofing is a smart investment, blending modern design with exceptional durability. But its performance and longevity rest squarely on the shoulders of the contractor you choose.
