Aluminium gutters are generally better for longevity, durability (withstanding extreme weather), and aesthetics (seamless options), while plastic (PVC) gutters are superior for low initial cost and easy DIY installation, though they can become brittle and are prone to leaks at joints over time. Your best choice depends on your budget, desired lifespan, and local climate, with aluminium offering a better long-term investment despite higher upfront costs.
UPVC guttering is less durable than aluminium. If exposed to sunlight and rain, plastic is at risk of damage and can even crack when something impacts it. Aluminium also beats uPVC in lifespan, with uPVC guttering having a potential lifespan of up to 20 years with good maintenance.
What are the advantages and disadvantages of aluminium gutters?
Aluminum is the most effective and widely used gutter material for modern homes. Copper and steel offer longevity and aesthetic appeal but at a higher cost. Vinyl and wood gutters are best for specific climates or historic restorations.
Although PVC gutters offer moderate resistance and are a functional option for basic projects, they do not match the strength and durability of steel, making them less recommended for high-traffic areas or where a long-lasting solution is desired.
Copper gutters have a lifespan of 100 years, far longer than any other gutter metal. Lastly, copper has a high recycle value. Also worth noting, copper is typically 16 ounces, which although thinner than aluminum gutters is equal in strength.
7 Reasons Why You Should Not Buy Plastic Gutters:
Vinyl – Vinyl is both the cheapest and least durable material used in gutter installation. Although this material is DIY friendly, it will need replacement much more quickly than the other materials. Vinyl is prone to cracking and other damage from temperature, weather, and impacts.
Like other plastic guttering, prolonged exposure to sunlight and rain will damage the material. UPVC can also easily crack when subjected to strong forces such as impact from falling branches, rocks, and hailstones. UPVC is expected to last from 10 years to 25 years, which is quite shorter compared to Aluminum.
The general rule of thumb is that your rain gutter slope should be anywhere from ¼ to ½ of an inch per every 10 feet of gutter. However, this may change depending on the home, as some houses can have differences in how their roof slopes along the gutters, among other factors.
Aluminum gutters have a life expectancy of 20 years, so you should expect to replace your gutters every 15 to 20 years. Since downspouts experience less wear and tear than gutters, aluminum downspouts may last 30 years. Older homes often have gutters made of copper.
In conclusion, despite its many advantages, aluminum can be weakened by various factors such as corrosion, fatigue, elevated temperatures, impact, and environmental factors.
When compared to traditional forms of roofing, Colorbond gutters combine versatility with a superior steel exterior that offers the perfect level of protection for Australian conditions. Durable, strong and beautiful, brand-new guttering can also guard your roof against damage and keep your home in excellent condition.
Drawbacks of Aluminum Gutters
Aluminum is more prone to denting than vinyl, especially when exposed to falling limbs or large hailstones. While aluminum does resist rust, if the paint chips or the surface coating wears off, corrosion can begin over time.
Obstacles to using aluminum instead of plastic
So why doesn't the beverage industry use the more sustainable aluminum exclusively? Cost: Aluminum cans are generally more expensive to produce than plastic bottles. Customer preference: Some customers prefer the taste, feel, and look of plastic bottles over aluminum cans.
Metal gutters like aluminium, steel and cast iron offer greater durability but come at a higher cost. Cast iron and copper are ideal for heritage or high-end properties where appearance and lifespan matter.
Summer is generally dry and hot, offering a perfect working environment for gutter installations. There are fewer chances of rain interruptions, and the materials tend to dry quickly.
Unlike aluminum gutters that come with seamless options, vinyl gutters are only available in sections. As a result, they're more likely to leak. The average life span for vinyl gutters is about a couple of decades because of their weather sensitivity. Aluminum gutters can better withstand adverse weather conditions.
Clogged or Blocked Gutters
The most common issue for any homeowner is dirty gutters. Each fall and spring, you will need to climb around the whole perimeter of your roof to clean out the clogged gutters.
Aluminum gutters are budget-friendly, rustproof, lightweight and come in a wide selection of colors. They are the most popular choice if you plan to install your own gutters. Vinyl gutters fit most budgets, come in several colors and are also a good choice for DIY installation. Copper doesn't mold, mildew or rust.
No, standard magnets will not be able to hold on to aluminum gutters, as aluminum is not a magnetic metal. You will need to use plastic gutter clips that will hook over the front lip of the gutter for a sure grip.
Your gutter guards might not be working if you notice water overflowing during rain. This often happens because guards can't handle heavy rainfall or become clogged with small debris. Even worse, some systems actually trap leaves and pine needles instead of keeping them out.
When comparing plastic and metal guttering, it is clear that installing a metal gutter system is the best option. Primarily, due to its cost effectiveness, lifespan and superior appearance. Aluminium guttering is the most popular metal guttering choice, and it is easy to see why.
One of the most significant advantages of not having gutters is the reduction in maintenance. Gutters require regular cleaning to remove leaves, twigs, and other debris that can clog them and prevent proper water flow. This maintenance can be time-consuming and often requires professional services, adding to the cost.
Vinyl gutters are one of the most affordable options, costing between $3–$6 per linear foot. They are lightweight and easy to install, making them a great choice for DIY enthusiasts.
