A metal roof is one of the most energy-efficient and long-lasting roofing options available on the UK market today.
Whether you're considering steel, aluminium, copper, or zinc, metal roofing offers superior weather resistance, fire safety, and long-term savings compared to traditional materials like asphalt shingles.
Recently we covered what the best roofing sheet to buy is. But how much does a metal roof actually cost?
Well, the answer does depend on the type of metal, installation complexity, roof size, and additional materials like underlayment and insulation.
In this guide, we’ll break down metal roofing costs per square metre, compare different materials, and explore installation expenses, maintenance requirements, and long-term value to help you decide if a metal roof is the right investment for your home.
Factors That Affect the Cost of a Metal Roof
The total cost of a metal roof varies depending on several key factors. Here's a quick summary of those factors:
- 💰 Material Type: Copper and zinc roofing are premium metals, while steel and aluminium are more budget-friendly. Our sister company, The Metal Roof Company, can supply the traditional hard metals, along with an experienced installer to carry out the project. Corrugated Metal Roofing Sheets are a cheaper option, and look brilliant on most property types.
- 🏠 Roof Complexity: Steeper, multi-level roofs require more materials and labour than simple designs. Steeper roofs require more materials and specialised labour to ensure safety during installation. Multi-level roofs with dormers, skylights, or chimneys involve extra flashing and custom-cut panels, increasing the overall expense. Curved or custom-shaped roofs demand skilled craftsmanship and premium materials, adding to both material and labour costs.
- 👷 Installation Costs: Professional labour varies by region, but complex roofs require higher fees. Flat or gently sloped roofs are easier and faster to install, reducing labour costs. Complex designs require more time and precision, leading to higher fees for professional installation. While possible for experienced homeowners, improper installation can lead to leaks, panel misalignment, and reduced lifespan—hiring professionals is recommended.
- 📏 Roof Size: The larger the roof, the more materials and time required. A larger roof means more panels, fasteners, and structural support, longer installation times and higher transportation and handling costs
- 🌡 Underlayment & Insulation: Additional layers for weatherproofing and energy efficiency increase costs. Underlayment (moisture barrier): Essential for protecting against leaks and condensation—£3 - £4.50 per square foot. Insulation helps regulate temperature and improves energy efficiency, especially in extreme weather conditions. Skipping underlayment is NOT an option—it ensures your metal roof performs well in all seasons and climates.
- 🎨 Coatings & Finishes: Protective coatings like PVC Plastisol or GreenCoat® Mica BT extend lifespan but add to the cost.
By understanding these factors, you can accurately estimate your total roofing expenses before starting your project. Let's go a bit deeper.
Metal Roofing Prices by Type (£ Per Square Metre)
Metal Type | Approx. Cost (£/m²) | Key Features |

How to Maintain a Metal Roof for Long-Term Savings
A well-maintained metal roof can last 50+ years, with some materials like copper and zinc exceeding 100 years.
Unlike traditional asphalt shingles, metal requires minimal upkeep to retain its durability, weather resistance, and aesthetic appeal.
Regular maintenance ensures that your investment remains in peak condition, preventing costly repairs down the line.
Here’s how to properly care for your metal roof:
🧼 Cleaning: Wash with mild detergent and water to prevent debris buildup.
- Wash the surface with a mild detergent and warm water using a soft sponge or low-pressure hose to remove dust, dirt, and organic buildup.
- Avoid harsh chemicals like bleach or ammonia, as they can weaken protective coatings and lead to premature fading or corrosion.
-
💡 Pro Tip: Clean your metal roof at least once a year or more frequently if you live in a coastal or heavily wooded area where salt and debris accumulation is common.
🎨 Re-Coating: Protective coatings extend lifespan—consider reapplying every 10-15 years.
- Metal roofs come with protective coatings such as PVC Plastisol, Polyester Paint, or Galvanised Zinc, but these coatings can wear down over time due to exposure to UV rays, heavy rain, and snow.
- Reapply a protective coating every 10-15 years to reinforce rust resistance and maintain the colour and finish of the panels.
- If your metal roof has a powder-coated finish, touch up any chipped or scratched areas to prevent further deterioration.
- For copper or zinc roofs, allow the natural patina to form for protection, but remove unwanted oxidation spots if necessary.
-
💡 Pro Tip: If your metal roof has painted panels, consider a UV-resistant sealant to reduce fading and prolong its appearance.
🔍 Regular Inspections: Check for loose fasteners, rust spots, or minor leaks twice a year.
- Inspect the roof twice a year (spring and autumn) for any loose fasteners, rust spots, or minor leaks that could worsen over time. This would be the same for polycarbonate roof sheets.
- Check for signs of water infiltration, particularly around seams, flashing, and roof penetrations like chimneys or skylights.
- Look for dents or deformations caused by falling debris, hail, or extreme weather conditions.
- Examine coatings and paint finishes to spot early signs of peeling, cracking, or discolouration.
🔩 Repairs: Address small dents or scratches early to prevent corrosion.
- Tighten loose screws or fasteners to prevent panels from shifting, especially after storms or high winds.
- Seal minor leaks early using roofing-grade silicone or polyurethane sealants to prevent water from seeping underneath panels.
- For small dents or scratches, use a matching touch-up paint or protective spray to stop rust from developing.
- If panels become severely damaged due to storms or impact, replace individual sheets or sections rather than waiting for the issue to spread.
- Ensure that flashing around vents, chimneys, and skylights is intact, as these areas are prone to leaks if not properly maintained.
-
💡 Pro Tip: When fixing any part of a metal roof, always use manufacturer-recommended fasteners and sealants to maintain warranty coverage.
