Zinc vs Aluminum Eavestrough Costs in Ottawa

Zinc eavestroughs are a premium product that costs significantly more than aluminum, with Ottawa installation prices running $30 to $55 per linear foot for zinc compared to $8 to $18 per linear foot for seamless aluminum. That makes zinc roughly three to four times the price of a standard aluminum eavestrough system, putting a full zinc installation on a typical Ottawa home with 150 linear feet in the range of $4,500 to $8,250 versus $1,200 to $2,700 for aluminum.

The high cost of zinc reflects both the material itself and the specialized installation it requires. Zinc eavestroughs are typically made from zinc-titanium alloy (the most common brand being VM ZINC or RHEINZINK), which is a European product that must be imported. The material is soldered at joints rather than sealed with caulk, similar to copper work, and not every Ottawa eavestrough contractor has experience soldering zinc. You will need to find a contractor with specific sheet metal or architectural metal experience, which limits your options and can increase labour costs.

So why would anyone pay three to four times more for zinc? The advantages are real and significant for the right home. Zinc develops a beautiful blue-grey patina over time that is self-healing — minor scratches and surface marks naturally weather to match the surrounding finish. Zinc is virtually maintenance-free and has an expected lifespan of 60 to 80 years in Ottawa's climate, compared to 20 to 30 years for aluminum. Zinc is also fully recyclable and considered one of the most environmentally sustainable building metals. It does not corrode the way steel does, and unlike aluminum, it does not require a factory-applied paint finish that can chip, fade, or peel.

However, zinc has some drawbacks in Ottawa's specific climate. Zinc is softer than aluminum and dents more easily from ice chunks, hail, and ladder contact. It also requires isolation from dissimilar metals to prevent galvanic corrosion — if your roof has copper flashing or your fascia has steel nails, direct contact with the zinc gutter will cause accelerated deterioration. A qualified installer must use compatible fasteners and separation barriers at every contact point.

From a practical standpoint, aluminum is the better value for the vast majority of Ottawa homes. The 20 to 30 year lifespan of quality aluminum eavestroughs is more than adequate when you factor in the significantly lower upfront cost. You could install aluminum eavestroughs three times over the lifespan of a single zinc system and still come out ahead financially. Zinc makes the most sense on high-end custom homes, architectural projects, or heritage restorations where the aesthetic and longevity justify the premium.

If you are considering zinc eavestroughs, ensure your quotes specify the exact alloy and gauge, soldering method, compatible hangers, and the installer's experience with zinc specifically. Given the specialized nature of this work, getting multiple quotes is even more important than usual.
