What Is The Least Expensive Type Of Roof

When a new roof is on the horizon, the first instinct for many homeowners is to find the cheapest option that still does the job. So what is the least expensive type of roof? The honest answer is that a few materials sit clearly at the budget end, with basic asphalt shingles and corrugated metal the most affordable for most homes, and rolled roofing the cheapest of all for sheds and simple structures. But cheapest upfront is not always cheapest over time, because a roof that needs replacing in ten years can cost more than one that lasts fifty. We connect homeowners with trusted roofing contractors across Australia every week, so we see the full range of roofing materials quoted and installed, and where the genuine value sits. This guide ranks the least expensive types of roof, weighs cost against lifespan, and helps you find the best value for your home, not just the lowest sticker price.

What Is The Least Expensive Type Of Roof?

Let us answer it head on. The least expensive type of roof is asphalt shingles, specifically basic three tab shingles, which remain the cheapest roofing material in most markets. They are quick to install, use less material than premium products, and need less labour, which keeps the roof cost down. Right alongside them sits corrugated steel roofing, the most affordable metal roof option and hugely popular in Australia, where asphalt shingles are far less common than in North America. For the very cheapest result on a shed, garage or simple structure, rolled roofing is cheaper still, though it lasts only a few years. So the budget podium is rolled roofing for short-term jobs, then three tab asphalt shingles and corrugated metal for homes. Each behaves differently, lasts a different length of time and suits a different climate, so we will work through the main roofing materials one by one.

Cheapest Roofing Materials Ranked

To choose well, it helps to see the main options side by side, from cheapest to dearest. Below we rank the common roofing materials by cost, with a quick note on each one's lifespan and where it makes sense. Remember that these are guides only: actual prices vary widely depending on your roof size, design, location and the grade you choose.

Rolled Roofing

Rolled roofing is the cheapest roofing material going, often costing well under other options per square. It comes in long rolls of asphalt-based sheet laid over a flat surface, and is fast and cheap to install. The trade-off is lifespan: rolled roofing lasts only about 5 to 8 years, so it is strictly a budget choice for sheds, workshops and low-slope outbuildings, never a home you care about. For a quick, disposable covering, though, nothing beats it on price.

Asphalt Shingles

Asphalt shingles are the most popular budget roof in many countries and the benchmark for affordable roofing. Basic three tab shingles are the cheapest, while architectural shingles and composite shingles cost a little more for a thicker, longer-lasting product. Asphalt shingles last anywhere from 12 to 30 years depending on quality, and asphalt shingles perform reasonably well in moderate climates. They handle various shapes of roof and come in many colours. The catch in Australia is that they are less common and can struggle with intense sun and severe weather compared with metal, so weigh the low upfront cost against a shorter life in harsh conditions. Where a roof already has a single layer of existing shingles, a new layer can sometimes be laid straight over the top to save on removal, though this is not always permitted.

Corrugated Metal And Steel Roofing

Corrugated steel roofing is the affordable metal champion and a staple on Australian homes, sheds and farms. Made from coated steel like Colorbond or Zincalume, it is lightweight, quick to install and far tougher than its low price suggests. Steel roofing handles harsh weather conditions, withstands strong winds, is fire resistant and reflects heat in hot climates. Metal roofs typically last 30 to 75 years with proper installation, so the cost per year is excellent. For most Australian homeowners chasing a cheap but genuinely durable roof, corrugated metal is the standout value, which is why we see it specified more than any other material.

Concrete Tiles

Concrete tiles are the budget-friendly option in the tile category and a long-standing favourite across Australian suburbs. They cost more upfront than metal or shingles but last at least 50 years, and individual tiles are cheap to replace. Concrete tiles are heavy, so the roof structure must carry the load, and they suit most houses with a traditional look. While not the cheapest roofing material outright, their long life makes them a cost effective choice for many homes that want a tile roof without the premium price of terracotta or slate.

Standing Seam Metal Roofing

Standing seam metal roofing is the premium cousin of corrugated steel, with raised seams that interlock for a sleek, watertight finish and a clean, modern look. It costs more than corrugated metal because of the extra material and labour in those raised seams, but it shares metal's strengths: long life, energy efficiency and excellent performance in severe weather. Standing seam metal is a worthwhile investment for a feature roof or a contemporary home, though it is not the cheapest way to get a metal roof. For pure budget, corrugated wins; for looks plus longevity, standing seam earns its keep. Other metal choices include lightweight aluminum shingles and steel metal shingles, which mimic the look of tile or slate at a fraction of the weight.

Clay And Terracotta Tiles

Clay tiles, including terracotta, sit above concrete in both price and prestige. They bring a timeless, colour-fast finish in earthy tones and can last over 100 years, easily outliving the home around them. Clay tile roofs cost more upfront and, like concrete, are heavy enough to need a strong roof structure. They are never the cheapest type of roof, but for heritage homes and traditional looks, their century-plus lifespan and natural insulation make them a sound long-term buy rather than a budget pick.

Slate, Wood And Copper: The Premium End

At the top of the price ladder sit the luxury materials, none of them cheap. A slate roof, made from natural slate, is among the most expensive of all, but slate roofs can last 75 to 150 years with minimal maintenance, the longest of any material. Wood shingles and wood shakes offer a natural, rustic look and last 20 to 60 years with proper maintenance, though they need care in damp conditions and bushfire zones. Copper roofing is rare, beautiful and extremely durable, ageing to a striking patina, but its price puts it well out of budget territory. These materials are about character and longevity, not saving money, so they sit at the opposite end from the cheapest roof options.

Cheapest Is Not Always Best Value

Here is the trap to avoid: the lowest upfront cost is not always the cheapest roof over its life. Think in cost per year, not just the sticker price. Rolled roofing might be cheapest to install, but replacing it every 5 to 8 years quickly overtakes a metal roof that lasts 50. Basic three tab asphalt shingles last 15 to 25 years, while corrugated metal lasts 30 to 75, so the slightly higher initial cost of metal often works out cheaper per year. Higher-quality roofing materials also come with better warranties and longer lifespans, plus stronger insurance coverage and resale value. Roof replacement costs add up fast if you do it twice in the time a better roof would have lasted once. So when comparing options, divide the price by the expected lifespan to find the real best value, and you will often find that a mid-priced metal roof beats the cheapest shingle on long-term cost. A good roof is also a worthwhile investment in the home itself, so a quality material that looks sharp and lasts can lift resale value, not just trim your running costs.

What Affects Your Roof Cost?

Material is the biggest factor, but several others shape your final roof cost. Roof size leads, since more roof means more materials and more labour. Roof design and complexity matter next: a simple gable is cheap, while a complex roof with many valleys, hips and features increases installation costs and material waste. A steep pitch raises labour because the work is slower and needs more safety gear. Labour costs themselves vary widely depending on your location and roof accessibility, with hard-to-reach roofs costing more. Professional installation is worth paying for even on a cheap material, because a poorly laid budget roof fails early and wipes out the saving. Finally, demand and local rates shift prices by region. The cheapest material on a large, complex, hard-to-access roof can still cost more than a pricier material on a small, simple one, which is why an on-site quote always beats a per square estimate.

Cheapest Roofs For Flat Surfaces

Flat roofs are a special case with their own cheap options. On a flat surface, pitched-roof materials like shingles and tiles do not shed water properly, so you need a waterproofing system instead. Rolled roofing is the cheapest, ideal for a shed or garage, lasting 5 to 8 years. A step up is membrane roofing, which lasts 20 to 35 years when maintained and forms a durable waterproof membrane over the roof. Built-up roofing, the traditional layered tar paper and bitumen system, can last 20 to 30 years with proper maintenance. For a low-cost flat roof on a home extension or carport, a quality membrane is usually the best balance of price and lifespan, while rolled roofing wins only where cost is the sole concern.

Climate Matters: Choosing For Australian Conditions

The cheapest roof for one home is wrong for another, because climate changes everything. In hot climates, a reflective metal roof keeps homes cooler and cuts energy costs, while dark asphalt shingles absorb heat. Near the coast, salt air corrodes some materials fast, so coastal-grade steel roofing or tiles outlast cheaper options. In areas of severe weather, a roof must withstand strong winds and heavy rain, where metal and tile beat lightweight shingles. In bushfire prone areas, a fire resistant, non-combustible material like steel or tile is essential, and wood shingles are a poor choice. Snowy and alpine zones, rare in Australia, favour steep, shedding roofs. The lesson is simple: the cost effective choice depends on where you live, so a cheap material that fails in your conditions is no bargain. Matching the roof to the local climate is as important as the price.

Energy Efficiency And Long-Term Costs

A cheap roof that drives up your power bills is a false economy, so factor in energy efficiency. Metal roofs, especially in light colours, reflect the sun's heat and can noticeably lower cooling energy costs in our climate, an energy efficient choice that pays back over time. Tile and slate offer natural insulation thanks to their thermal mass, holding temperatures steadier through the day. Adding roof insulation and good ventilation under any roof boosts efficiency further. A green roof, or living roof, is a niche option that adds natural insulation and absorbs heat, though it carries a higher initial cost and needs structural support. For most homeowners, a reflective metal roof or well-insulated tile delivers the best balance of low upfront cost and ongoing energy savings, which is part of what makes them such good value.

Low Maintenance And Lifespan

Cheap roofs and low maintenance do not always go together, so consider upkeep before you buy. Metal roofs are among the lowest maintenance, needing little more than an occasional wash to perform for decades, and they resist moss and rot. Concrete and clay tiles are durable but need the odd cracked tile replaced and periodic cleaning. Asphalt shingles need checking for curling or lost granules as they age. Wood shingles demand the most regular maintenance, especially in damp conditions. The rule across every material is that a roof that is properly maintained lasts far longer than one that is neglected, so even the cheapest roof rewards a little care. When you compare options, weigh the ongoing maintenance alongside the upfront price, because low maintenance is a real long-term saving and a longer average lifespan.

How To Get The Best Value On A New Roof

Finding the cheapest roof that is actually worth having comes down to a few smart moves. Get at least three quotes from licensed roofing contractors and compare them like for like, since prices vary widely depending on the contractor. Always insist on professional installation, even with a budget material, because quality fitting is what makes a cheap roof last. Choose the most durable material your budget allows rather than the absolute cheapest, since a small step up often doubles the lifespan. Match the material to your climate and roof design, and ask about warranties and what each option means for your insurance coverage. A fully itemised quote lets you see exactly where your money goes. Combine these and you will land on the best value roof for your home, not just the lowest price.

Signs You Need A New Roof, Not Just A Repair

Before spending anything, it is worth knowing whether you need a full new roof or just a repair, since a patch is always the cheapest fix when it is enough. Telltale signs that a roof is past saving include widespread leaks and water stains, sagging sections, and large numbers of cracked tiles or rusted, lifting metal sheets. On an asphalt shingle roof, curling shingles and bare patches where the granules have worn away signal the end of its life. A roof beyond about 80 percent of its expected lifespan rarely repays further repairs. If only a small area is damaged on an otherwise sound roof, a targeted repair is the least expensive path by far. But once damage is widespread, repeated repairs cost more than a new roof would, so a fresh start in an affordable material is the smarter money.

DIY Versus Professional Roofing

It is tempting to cut costs by doing roofing yourself, and for a small shed with cheap rolled roofing that can work. For a home, though, DIY rarely pays. Roofing is dangerous work at height, mistakes cause leaks that cost far more to fix than the labour saved, and a botched job can void material warranties and affect your insurance coverage. Professional installation also gets the flashing, ventilation and fixings right, which is what makes even a cheap roof last its full lifespan. In Australia, metal roofing is fitted by licensed roof plumbers for good reason. The sensible saving is not skipping the professional, it is choosing an affordable material and a fair-priced, qualified roofer, then letting them install it properly the first time. That is how a budget roof becomes a long-term asset rather than a recurring headache.

Real Roof Choices From Our Network

Real homes show how the cheapest sensible choice changes with circumstances. In Dubbo, where summers are fierce, a family on a budget skipped asphalt shingles for a light corrugated Colorbond roof at around $60 per square metre, cooler in the heat and rated for 40-plus years, cheaper per year than any shingle. In Whyalla, on the South Australian coast, owners chose coastal-grade steel roofing over a cheaper standard sheet, paying a little more upfront to beat the salt air that would have corroded the budget option within a decade. And in Burnie, in Tasmania's cool, damp north, a homeowner avoided wood shingles, which rot in those conditions, and reroofed in concrete tiles for their durability and natural insulation. Three homes, three climates, each proving that the least expensive type of roof is the one that lasts longest where you actually live, not the one with the lowest sticker price.

Conclusion And Your Next Step

So, what is the least expensive type of roof? For most homes, basic three tab asphalt shingles and corrugated steel are the cheapest to install, with rolled roofing the budget pick for sheds and flat outbuildings. But the smartest spend is rarely the cheapest sticker price. Corrugated metal usually wins on long-term value, lasting 30 to 75 years where a cheaper shingle lasts 15 to 25, and the right roof depends on your climate, your roof design and how long you plan to stay. Weigh upfront cost against lifespan, energy efficiency and maintenance, and you will find the genuine best value rather than the cheapest mistake.

Frequently Asked Questions

Here are the questions our network hears most about cheap roofing options.

What Is The Cheapest Roofing Material?

The cheapest roofing material is rolled roofing for sheds and flat outbuildings, lasting only 5 to 8 years. For homes, basic three tab asphalt shingles and corrugated steel are the most affordable. Corrugated metal is usually the better buy, since it lasts 30 to 75 years against 15 to 25 for shingles.

Are Asphalt Shingles Or Metal Cheaper?

Asphalt shingles are usually cheaper to install upfront, often the lowest-cost roof for a home. Corrugated metal costs a little more initially but lasts far longer, 30 to 75 years versus 15 to 30 for shingles, so it is frequently cheaper per year and better suited to Australia's harsh sun and severe weather.

What Is The Longest-Lasting Roofing Material?

Slate roofs last the longest, 75 to 150 years or more with minimal maintenance, followed by clay tile roofs at over 100 years. Metal roofs last 30 to 75 years and concrete tiles at least 50. These premium and mid-range materials cost more upfront but deliver excellent value over a very long life.

Is A Cheap Roof Worth It?

It can be, if you choose the cheapest durable material rather than the absolute lowest price. A budget corrugated metal roof offers great long-term value, while the truly cheapest options like rolled roofing suit only sheds. Always weigh upfront cost against lifespan, maintenance and your climate before deciding.

What Roof Is Best For Hot Australian Climates?

A light-coloured metal roof is ideal for hot climates, reflecting the sun's heat to keep homes cooler and lower energy costs. Tiles also perform well thanks to their thermal mass and natural insulation. Dark asphalt shingles absorb more heat, so they are a weaker choice in the hottest parts of Australia.
