Aluminum’s cost-effectiveness and widespread accessibility make it a top choice for constructing gutter systems. However, aluminum gutters might not be the best for every home. Our guide explores the advantages and disadvantages of aluminum gutters, their cost, and how they compare to other gutter types. We’ll also provide maintenance tips and answer frequently asked questions to help you decide whether aluminum gutters are right for your home.

Advantages of Aluminum Gutters

Aluminum is one of the most versatile gutter materials available. It’s affordable, easy to install, and lasts over 20 years. Below is a closer look at all of its advantages.

Affordability

Aluminum gutters have a lower upfront cost than other types of gutters, such as copper, steel, and zinc gutters. Their lighter weight makes them easy to install, reducing labor costs.

Customizability

Aluminum gutters come in various styles and colors for do-it-yourself (DIY) or professional installation. K-style gutters can blend with your roofline, fascia-style gutters create a streamlined contemporary look, and half-round gutters are a great option for noise reduction. You can also choose between seamed aluminum gutters or seamless gutters that run the entire length of your home.

Durability

Aluminum gutters are strong and durable. These gutters are also rust-resistant, making them ideal for most climates. Aluminum even resists thinning when exposed to the elements and has a high strength-to-weight ratio that allows it to withstand snow, hail, and ice. Well-maintained aluminum gutters can last for more than 20 years.

Easy Installation

Aluminum gutters don’t have specialized installation requirements, so the installation process is usually straightforward and a great option for DIYers. The simple installation makes aluminum gutters more affordable if you hire a professional to install the gutters for you.

Disadvantages of Aluminum Gutters

Aluminum gutters are ideal for most homeowners, but you must consider whether their poorer weather resistance and high maintenance are worth the money you save.

Easily Damaged

Aluminum has a high strength-to-weight ratio, but its lightweight design doesn’t hold up as well as stronger metals against forceful conditions. Pressure during installation, accidental contact with a ladder, and storm-swept debris can dent aluminum gutters. Large dents can cause clogs and cracks, leading to more damage and early replacement. Aluminum gutters are also more vulnerable to leaks caused by heavy snow loads, hail, and ice accumulation.

High Maintenance

Aluminum gutters are rust-resistant but lack the superior corrosion-resistant properties of copper, which prevent algae, moss, and mold growth. Additionally, their tendency to clog typically requires professional cleanings twice a year to prevent rust and corrosion.

Homeowners often paint aluminum gutters to match their home’s exterior, but the outer finish is highly susceptible to cracking and fading with UV exposure, requiring a fresh coat of paint every few years.

Limited Thermal Resistance

Aluminum gutters withstand the elements in most climates but expand and contract with temperature changes. Expansion and contraction in extreme temperatures can lead to leaks in joints and excessive sagging.

Cost of Aluminum Gutters

Affordability is one of the primary benefits of aluminum gutters. Low material costs and an easy installation lead to a lower upfront investment, making aluminum an ideal choice for homeowners on a budget.

The national average cost to install aluminum gutters ranges around $900–$3,300.* However, many factors can affect the cost of aluminum gutters, including the size of your home, the type of gutters you choose, and whether the project is a new installation or replacement. Complex roof styles and roof height can also add to the installation cost.

Upfront Costs

DIY versus professional installation: If you already own the necessary tools to complete the job, choosing a DIY installation means you’ll pay for just the materials. However, your work won’t be covered by a warranty.
Gutter gauge: Aluminum gutters are available in 0.025-, 0.027-, and 0.032-inch thicknesses. A thinner gauge reduces upfront costs but damages more easily.
Gutter style: The style of gutter you choose will impact the price. Expect to pay $5–$7 for materials and $6–$14 for installation if you decide on K-style gutters. Half-round gutters typically cost $7–$11 for materials and $8–$18 for installation. If you opt for European-style gutters, you’ll pay around $9–$13 for materials and $10–$20 for installation.
Gutter type: Aluminum gutters are available in precut sections or one seamless piece that’s custom-made on-site. Sectional aluminum gutters cost $7–$10 per linear foot, and seamless aluminum gutters cost $9–$13 per linear foot.
Home levels: Installing gutters on a two-story home increases the price due to the need for longer aluminum downspouts and scaffolding equipment required to reach higher roofs. Installation costs on a one-story home range from $300–$2,400. A two-story can cost $600–$4,000, and a three-story home $900–$5,440.
Home size: Larger houses require more materials and labor, which increases the total cost of the project. Aluminum gutter installation on a 1,000-square-foot home ranges from $480–$2,000, while installation for a 3,000-square-foot home costs $1,200–$5,440.
Installation: The average cost of aluminum gutters with installation ranges from $6–$20 per linear foot.
Materials: The average cost of aluminum gutters is $5–$13 per linear foot. You’ll also need to purchase gutter hangers, brackets, sealant, lag screws, and downspouts, which vary in cost.
Project scope: Gutter installation on complex rooflines with multiple corners, gables, and pitches costs more. The removal and disposal of old guttering also add $80–$300 to the total installation cost.

Long-Term Costs

Maintenance: Aluminum gutters require cleaning and painting. Expect to pay $125–$225 for professional cleaning twice a year.
Repairs: The average cost to repair damaged aluminum gutters ranges from $100–$450, depending on the extent of the damage. Replacing severely damaged sections costs $6–$17 per linear foot.
Replacement: Full aluminum gutter replacement includes the cost of removing your old gutter system and installing a new one. The average cost to remove old gutters ranges from $75–$300, but lower costs may not include hauling away the old guttering material.

Life Span of Aluminum Gutters

New aluminum gutters typically last 20–30 years under ideal conditions. However, the longevity of your aluminum gutter system depends on the following.

Care: Routine maintenance, including regular gutter cleaning and occasional painting, will extend the life of your aluminum gutters. Schedule a professional cleaning at least twice a year and repaint them when the outer surface starts to crack or peel.
Environment: Aluminum gutters aren’t a great option for coastal areas, where the high salt content and moisture in the air accelerate the corrosion process.
Weather conditions: Climates subject to rapid temperature changes and severe storms can shorten the life span of aluminum gutters due to damage from contraction and expansion and impact from storm debris.

Aluminum vs. Other Gutter Types

Aluminum gutters aren’t the only option for directing rainwater away from your home. Consider whether the longevity of copper gutters or the affordability of vinyl outweigh the benefits of aluminum gutters before making your choice.

Copper Gutters

Copper gutters are a stylish gutter option that can add elegance to your home. They don’t require painting and develop an attractive patina over time.
