Metal Roof Types: What You Need to Know

Understanding the different metal roof types can make all the difference when choosing a metal roof for your home or business. At All Needs Plumbing, we’ve seen firsthand how picking the right metal roofing material boosts your property’s look and protects it from Sydney’s varied weather. Whether in St. George, Inner West, Sutherland Shire, or anywhere in Sydney, knowing your options helps you make smart decisions, especially regarding gutter cleaning and maintenance.

Common Metal Roof Types and Materials

Corrugated Metal Roofing

Corrugated metal roofs are the classic wavy sheets on sheds, garages, and homes. Their distinctive ridges give them strength and flexibility, making them lightweight yet durable. Because of their shape, water runs off quickly, which helps prevent pooling and reduces the chance of leaks. This quick shedding of water also means less debris sticks around the roof, making gutter cleaning easier. 

Corrugated roofs usually come in steel, zinc, or aluminium. Steel is strong and budget-friendly, but it can rust if not properly coated. Aluminium resists rust better, making it great for coastal homes where salt air is a problem. Zinc is less common but offers good corrosion resistance and a longer lifespan.

Standing Seam Metal Roofing

Standing seam roofs feature tall, raised seams that interlock panels together, with fasteners hidden beneath the seams. This design creates a smooth, sleek appearance and offers superior weather resistance. Because the fasteners are concealed, there’s less chance of water penetration through screw holes, which is a common leak point in other metal roofs. 

This makes standing seam roofs highly durable and low-maintenance. Their smooth surface also means less debris buildup, which helps keep gutters cleaner for extended periods. These roofs typically come in steel, aluminium, or copper. Copper standing seam roofs are a premium choice, offering decades of maintenance-free performance and developing a beautiful green patina.

Metal Shingles and Tiles

Metal shingles or tiles are a great option if you want the classic look of shingles or tiles but with metal’s durability. These products are made from steel, aluminium, or copper and designed to mimic traditional roofing materials like slate or terracotta tiles. They offer excellent weather resistance and can add a unique aesthetic to your home or business. 

Because they have flatter surfaces than corrugated or standing seam roofs, debris such as leaves and twigs can collect more easily. To prevent blockages, you’ll want to keep a close eye on your gutters and schedule regular cleaning.

Copper Roofing

Copper roofs are known for lasting a very long time and looking beautiful. They can last over 100 years, often outliving the building itself. Copper naturally resists corrosion and requires very little maintenance. Over time, it develops a greenish patina that many homeowners find attractive and unique. 

While copper roofs are more expensive upfront, their durability and low upkeep make them a worthwhile investment. Copper handles extreme weather well and is fire-resistant, adding to its appeal.

Zinc and Aluminium Roofing

Zinc roofs are made from a blend of zinc, aluminium, and copper, which gives them excellent corrosion resistance and a long lifespan. Zinc is also environmentally friendly because it’s recyclable and requires minimal maintenance. 

Aluminium roofs are very light and don't rust easily, which makes them perfect for homes near the coast where salt air can speed up corrosion. An aluminium or zinc roof will keep your house cooler in the summer and help you save money on your energy bills.

Pro-Tip: Trim overhanging branches near your metal roof. This simple step reduces leaf litter and debris falling into gutters, saving time and protecting your roof from scratches and moss growth. Plus, it reduces the risk of branches damaging your roof during storms.

How Metal Roof Types Affect Gutter Cleaning and Maintenance

Different metal roof profiles impact how much debris ends up in your gutters. For example, corrugated roofs with their ridges can channel leaves, twigs, and other debris into gutters more than smooth standing seam roofs. This means gutters under corrugated roofs might clog faster, leading to water overflow and potential damage to your roof edges or walls.

If you want to avoid these problems, you need to clean your gutters often. If your gutters get clogged, water can back up and damage your metal roof or let water into your home. Keeping gutters clear ensures rainwater flows freely away from your property, protecting your roof and foundation.

Pro-Tip: Schedule gutter cleaning at least twice yearly, especially after storms or heavy winds. This keeps things clear so water doesn't back up and damage your roof or walls. You should clean your gutters more frequently if you live near many trees.

FAQs About Metal Roof Types

What is the biggest problem with metal roofs?

Noise during heavy rain or hail is a common concern, as metal can amplify sound. However, with proper insulation and professional installation, this can be minimised. Another issue is corrosion, especially in humid or coastal environments. Choosing the right materials and coatings helps prevent rust and extends your roof’s lifespan.

What kind of metal roof does not break down easily?

Copper roofs are the longest-lasting, often exceeding 100 years. Zinc roofs also offer impressive longevity, while steel and aluminium roofs typically last 40 to 60 years, depending on maintenance and environmental conditions.

When should you not use a metal roof?

Metal roofs may not be the best choice if you have a limited budget because of their higher upfront cost. They also might not suit buildings that can’t support the weight, or proper insulation isn't possible if noise is significant or a concern. Some heritage or local council regulations may also restrict metal roofing in certain areas.

What happens if lightning strikes a metal roof?

Metal roofs don’t attract lightning more than other roofing materials. If lightning strikes, metal safely conducts the electricity to the ground, reducing fire risk compared to non-metal roofs.

Do metal roofs leak over time?

A metal roof is usually less likely to leak than a regular roof. However, poor installation, damaged fasteners, or ageing sealants can cause leaks. Regular inspections and maintenance will help keep your roof dry.
