⭐⭐⭐⭐⭐ 4.9/5 | 250+ Homes | Licensed & Insured | 15+ Years in the Waikato

Trying to pick the right roof for your shed can feel like a big decision. You want something that lasts, looks good, and doesn’t break the bank, especially with Waikato’s changing weather. Whether you’re building a new shed or replacing an old, leaky roof, the material you choose makes a huge difference.

This guide will walk you through the two most popular choices for shed roofing: metal and asphalt shingles. We’ll explore their pros, cons, and what makes each option shine, helping you decide which one is the perfect fit for your shed in 2025.

Quick Verdict: Metal Roofing vs. Asphalt Shingles for Your Shed

Honestly, there’s no single “best” option; it really comes down to your priorities, budget, and the specific conditions your shed faces. If long-term durability, low maintenance, and modern aesthetics are key, metal roofing often takes the lead, especially with Waikato’s rainfall. However, if you’re looking for a more budget-friendly option with a traditional look and easier DIY potential, asphalt shingles are a solid choice that can still perform well.

Understanding Metal Roofing vs. Asphalt Shingles

When it comes to shed roofing, these two materials stand out. They both offer protection, but they do it in very different ways, each with its own set of advantages and disadvantages. Knowing these differences helps you make an informed decision for your Waikato property.

What is Metal Roofing?

Metal roofing for sheds typically involves panels made from steel or aluminum. These can come in various profiles, like corrugated sheets or standing seam panels. Metal roofs are known for their strength and modern look. They’re built to last, often for several decades, and can handle a lot of what New Zealand weather throws at them. The metal is usually coated to prevent rust and can come in many colours, offering a sleek finish for your shed.

What are Asphalt Shingles?

Asphalt shingles are a very common roofing material, made from a base mat (usually fiberglass) coated with asphalt and ceramic granules. For sheds, you’ll often see them in a traditional three-tab style or a more robust architectural style. They offer a classic, textured appearance and are generally more flexible in terms of installation for homeowners. They’ve been a go-to for decades because they’re reliable and relatively easy to work with.

Key Differences at a Glance

The main distinctions between metal and asphalt shingles are their lifespan, initial cost, maintenance needs, and how they look. Metal roofs typically last much longer, require less upkeep, and come with a higher upfront cost but often pay off over time. Asphalt shingles are usually cheaper to install initially, have a shorter lifespan, and might need more attention down the line. They also offer a more traditional look, while metal tends to be more contemporary.

Metal Roofing: Full Breakdown

Metal roofing has seen a huge surge in popularity, not just for sheds but for residential and commercial buildings too. It offers a combination of resilience and style that’s hard to beat, especially in the Waikato region.

How Metal Roofing Works

Metal roofing panels are typically installed in overlapping sections, secured directly to the shed’s roof deck or purlins. The design allows for expansion and contraction with temperature changes, and systems like standing seam hide fasteners for a clean look and enhanced weather protection. This installation method creates a strong, continuous barrier against the elements.

Key Features of Metal Roofing

  • Exceptional Durability: Metal roofs are incredibly tough, able to withstand heavy rain, strong winds, and even hail without much trouble. This is a big plus for sheds in exposed areas.McElroy Metal
  • Long Lifespan: You can expect a metal roof to last 50 years or even more, which means you likely won’t ever need to replace your shed’s roof again.Sheffield Metals
  • Low Maintenance: Once installed, a metal roof mostly takes care of itself. There are no granules to wash off and fewer areas for moss or lichen to take hold, which is a common issue with other materials in damp climates.
  • Fire Resistance: Metal is non-combustible, giving it a Class A fire rating, a great safety feature for any structure.McElroy Metal
  • Variety in Style and Color: Metal roofing isn’t just corrugated tin anymore. It comes in a wide range of profiles and colors, from classic steel to modern standing seam, allowing you to match your shed to your home or create a unique look.
  • Energy Efficiency: Lighter-coloured metal roofs can reflect sunlight, keeping your shed cooler in the summer months, which is great if you use it as a workshop or storage for sensitive items.

Pros of Metal Roofing

  • Very long-lasting, often outliving the shed itself.
  • Resistant to fire, rot, mildew, and insects.
  • Handles extreme weather conditions well, including heavy winds and rain.
  • Low maintenance requirements; rarely needs repairs if installed correctly.
  • Available in many colors and styles for a modern finish.
  • Can be made from recycled materials and is often recyclable at the end of its life.

Cons of Metal Roofing

  • Higher initial cost compared to asphalt shingles.
  • Can be noisy during heavy rain or hail if not properly insulated.
  • Installation can be more complex, often requiring professional expertise.
  • Damage, such as large dents, can be difficult to repair invisibly.

Pricing for Metal Roofing

The cost of metal roofing for a shed can be higher upfront than asphalt shingles. Prices vary widely based on the type of metal (steel, aluminum), the profile (corrugated, standing seam), and the complexity of the shed’s roof. For metal panels, you might expect to pay more per square foot for materials and installation compared to basic shingles. While specific New Zealand pricing for shed roofing can fluctuate, general estimates for metal roofing range from $120 to $900 per square (100 square feet) for materials alone, with installation adding to that. This higher initial investment is balanced by its exceptional longevity and low maintenance over time.

Best Use Cases for Metal Roofing

  • Sheds in areas prone to harsh weather, like strong winds or heavy rainfall in Waikato.
  • Workshops or storage sheds that need maximum protection and durability.
  • Homeowners seeking a modern aesthetic or a roof that matches a contemporary home.
  • Those looking for a very low-maintenance option that will last for decades.
  • Sheds where energy efficiency is a consideration to keep interiors cooler.

Asphalt Shingles: Full Breakdown

Asphalt shingles remain a favourite for many shed owners, and for good reason. They offer a blend of affordability, traditional aesthetics, and proven performance that appeals to a wide range of budgets and tastes.

How Asphalt Shingles Work

Asphalt shingles are installed in overlapping layers, starting from the bottom edge of the roof and working upwards. Each shingle is fastened with roofing nails, and the asphalt coating and ceramic granules bond together, creating a waterproof seal. This layered approach helps shed water effectively, making them a common choice for sloped roofs.

Key Features of Asphalt Shingles

  • Affordability: Asphalt shingles are typically the most cost-effective roofing material, making them popular for budget-conscious projects.
  • Ease of Installation: For smaller shed projects, asphalt shingles can be a DIY-friendly option, especially three-tab varieties, allowing homeowners to save on labour costs.
  • Wide Range of Styles and Colors: Brands like GAF and CertainTeed offer a vast selection, including architectural shingles that mimic wood shakes or slate, allowing for great aesthetic flexibility.GAF, CertainTeed
  • Good Weather Protection: Quality asphalt shingles offer reliable protection against rain, wind, and UV rays. GAF Timberline HDZ and CertainTeed Landmark shingles, for example, have features like advanced algae protection and strong adhesion against wind uplift.GAF
  • Fire Resistance: Most asphalt shingles have a Class A fire rating, providing good protection against external fire sources.

Pros of Asphalt Shingles

  • Lower upfront cost for both materials and installation.
  • Easily accessible from most hardware stores and roofing suppliers.
  • DIY-friendly for those with basic carpentry skills.
  • Offers a traditional look that can match many residential homes.
  • Good sound dampening properties compared to metal during rain.

Cons of Asphalt Shingles

  • Shorter lifespan (typically 15-30 years) compared to metal roofing.
  • Requires more maintenance over its lifetime, such as occasional repairs or granule loss.
  • Can be susceptible to moss and algae growth, especially in damp, shaded Waikato environments.
  • Less durable against extreme impacts like large hail compared to metal.

Pricing for Asphalt Shingles

Asphalt shingles are generally the most affordable option for shed roofing. Basic three-tab shingles can be very inexpensive per square, with architectural shingles costing a bit more but still less than most metal options. In New Zealand, asphalt shingles typically fall into the $100 to $200 per square (100 square feet) range for materials. This makes them a popular choice for those looking to keep initial costs down.

Best Use Cases for Asphalt Shingles

  • Budget-conscious projects where initial cost is a primary concern.
  • Sheds where a traditional or residential aesthetic is desired to match a nearby home.
  • DIY enthusiasts who want to install their own shed roof.
  • Smaller sheds or those requiring less heavy-duty protection.
  • Areas where future roof replacement is not a major concern within 20-30 years.

Side-by-Side Comparison: Shed Roofing Materials

Let’s put metal roofing and asphalt shingles head-to-head on the most important factors for your shed in Waikato.

Feature Comparison

  • Lifespan: Metal (50+ years) significantly outlasts Asphalt Shingles (15-30 years).
  • Durability: Metal offers superior resistance to strong winds, hail, and fire. Asphalt is durable but can be prone to granule loss and cracking over time.
  • Maintenance: Metal requires minimal maintenance. Asphalt may need occasional repairs, cleaning, and is more prone to moss/algae.
  • Aesthetics: Metal offers a modern, sleek look with varied profiles. Asphalt provides a traditional, textured appearance. Both come in many colours.
  • Weight: Metal is lighter than asphalt shingles, which can reduce stress on the shed’s structure.
  • Environmental Impact: Metal is often made from recycled content and is fully recyclable. Asphalt shingles are usually petroleum-based and less commonly recycled.

Price Comparison

This is where the biggest difference usually lies. Metal roofing has a higher initial material and installation cost, but its long lifespan means a lower cost-per-year over the life of the roof. Asphalt shingles are cheaper to buy and install upfront, but you’ll likely replace them at least once (maybe twice) for every metal roof, increasing their long-term cost.

Ease of Installation Comparison

For a DIY project, asphalt shingles are generally easier for an average homeowner to install. They are less specialised and require simpler tools. Metal roofing, especially standing seam, often requires specific tools and expertise to ensure proper sealing and cut lines, making professional installation highly recommended.

Performance in Waikato Weather

The Waikato region experiences a mix of conditions: plenty of rain, some strong winds, and varying temperatures. Both materials perform well, but metal has an edge in extreme conditions. Its seamless panels and durable coatings make it highly resistant to our frequent rainfall and prevent leaks. Its resistance to high winds is also excellent. Asphalt shingles hold up too, but prolonged dampness can encourage moss growth, and strong gusts can sometimes lift or damage older shingles if not perfectly installed.

Which Should You Choose for Your Shed Roofing?

The right choice depends on what’s most important to you for your shed.

Choose Metal Roofing If…

  • You want the longest-lasting roof possible for your shed.
  • You prefer minimal maintenance and don’t want to worry about roof repairs for decades.
  • Your budget allows for a higher initial investment for long-term value.
  • You’re looking for a modern aesthetic or need a roof that stands up to Waikato’s strong winds and heavy rain.
  • You want an energy-efficient option to keep your shed cooler.

Choose Asphalt Shingles If…

  • You need a budget-friendly option for your shed’s roof.
  • You prefer a traditional look that blends well with most homes.
  • You’re planning a DIY project and want a material that’s easier to work with.
  • Your shed is small, or you don’t require the absolute maximum lifespan from your roofing material.

Considering Other Shed Roofing Options

While metal and asphalt shingles are the most common, there are other materials that might suit very specific needs for your shed:

  • Ondura Corrugated Panels: These are lightweight asphalt-saturated organic fiber panels. They’re very affordable and easy to DIY, great for small, budget-friendly sheds, though less durable than metal or premium shingles.Ondura
  • Cedar Shakes/Shingles: For a high-end, rustic look, cedar shakes offer natural beauty and good insulation. However, they are expensive, require maintenance, and can be a fire risk if untreated.
  • Rubber Roofing (EPDM): Excellent for flat or very low-slope shed roofs, offering superior waterproofing and durability. It’s often professionally installed and best for specific roof designs.Firestone Building Products
  • TPO Roofing: Similar to EPDM, TPO is a single-ply membrane ideal for low-slope roofs. It’s known for energy efficiency and durability, often used in commercial applications but suitable for larger, modern sheds.GAF

These options cater to particular aesthetic or functional requirements, but for most sheds, the metal vs. asphalt shingle decision covers the primary considerations.

FAQ — Shed Roofing Choices

1. What is the most durable shed roofing material for Waikato weather?

For sheer durability and resistance to Waikato’s specific weather (rain, wind), metal roofing generally outperforms asphalt shingles. It lasts longer and stands up better to harsh conditions over many decades.

2. How much does it cost to re-roof a shed in New Zealand?

The cost to re-roof a shed in New Zealand varies greatly depending on the size of the shed, the chosen material, and whether you DIY or hire professionals. Asphalt shingles generally offer a lower upfront cost than metal roofing. For accurate pricing, always get a quote from a local Waikato roofing company like CTR Roofing Ltd.

3. Can I install shed roofing myself?

Yes, smaller shed roofing projects, especially with asphalt shingles or corrugated Ondura panels, can be DIY-friendly if you have basic construction skills and the right tools. Metal roofing, particularly standing seam, is more complex and often benefits from professional installation to ensure a watertight and long-lasting finish.

4. How long does shed roofing last?

The lifespan of shed roofing materials varies significantly: asphalt shingles typically last 15-30 years, while metal roofing can last 50 years or more. Factors like installation quality, maintenance, and local weather conditions also play a big part.

5. Are there eco-friendly shed roofing options?

Yes! Metal roofing is often made from recycled content and is fully recyclable at the end of its life, making it a good eco-friendly choice. Some asphalt shingles can also be recycled, though local facilities for this are less common.

6. Does shed roofing need insulation in Waikato?

Whether your shed roof needs insulation depends on its purpose. If you’re using your shed as a workshop, office, or for storing temperature-sensitive items, insulation can significantly improve comfort and protect contents. For simple storage, it might not be necessary.

7. Can I match my shed roof to my house roof?

Absolutely! Many homeowners choose roofing materials and colours for their shed that match their main house to improve aesthetic appeal and curb appeal. Both asphalt shingles and metal roofing come in a wide array of colours that can complement any home style.

8. What factors should I consider when choosing shed roofing?

Key factors include budget (initial vs. long-term), desired lifespan, aesthetic preferences, maintenance requirements, the slope of your shed roof, and how well the material stands up to local Waikato weather conditions like rain and wind.

9. What is the best shed roof style for drainage in heavy rain?

For heavy rain drainage, a good slope is crucial regardless of material. Gable or gambrel roof styles, combined with smooth materials like metal or well-installed asphalt shingles, are very effective at shedding water quickly. Metal roofing’s seamless panels are particularly effective in preventing leaks during downpours.
