Eavestroughs & Downspouts

About Eavestroughs & Downspouts
Water management starts at the roofline. A correctly specified eavestrough system channels spring runoff, summer downpours, and snowmelt away from your foundation, siding, and landscaping. Pro Materials supplies Kaycan rainware in aluminum and vinyl: 5" and 6" K-style aluminum eavestrough, K-Snap and U-Snap vinyl systems, a solid vinyl half-round profile, and the matching downspouts, elbows and outlets, plus gutter protection from Kaycan and Alu-Rex.
Everything from the eavestrough to the gutter guard - sourced from a single supplier, matched for compatibility, and priced for trade volume. Every line we carry is built and sold for the Canadian market, which means heavy snow loads, freeze-thaw cycling and the temperature swings Ontario contractors work through. We supply contractors, builders and homeowners across York Region, the GTA, Simcoe County and Durham Region.

Eavestroughs & Downspouts Buying Guide
Key factors to evaluate when specifying eavestroughs & downspouts for your project.
Profile and size
We stock Kaycan aluminum K-style eavestrough in 5" and 6". A 6" trough carries noticeably more water than a 5", so step up wherever runoff concentrates: large roof planes, steep pitches, and valleys that dump two roof faces into one run. A half-round trough carries less than a K-style of the same nominal width; Kaycan's Classic half-round comes in solid vinyl. Our eavestrough guide walks the sizing decision.
Aluminum or vinyl
Kaycan coats its own aluminum coil in-house, and its aluminum rainware comes with the full component line: hangers, corners, drop outlets, end caps and gutter wedges. The vinyl systems are solid PVC with cement-welded joints and no compression seals: K-Snap in 6 colours, U-Snap in white, and the Classic half-round in brown and white. Kaycan rates their heavy-duty hangers for ice and snow loads. We do not stock steel eavestrough.
Coil gauge
Seamless runs are formed on site from coil, and Kaycan's gutter coil comes in .023" and .027" gauge.
Gutter guards
Pine needles decide the product. The Alu-Rex dual-layer guards (DoublePro, Hover Pro and Gutter Clean Pro) carry a lifetime clog-free warranty that includes coniferous areas; the single-layer Gutter Clean System and T-Rex carry a 25-year prorated clog-free warranty that excludes conifers. Our gutter protection page lists every guard we stock.
Colour matching
Match the eavestrough to the fascia, or pick a neutral that disappears against it. Our exterior house colours guide covers matching the eavestrough to the siding or using it as part of a contrasting frame. Kaycan's gutter coil comes in a long list of colours and two-tone combinations, and K-Snap vinyl in six.
Downspouts
Kaycan makes aluminum downspouts in 2"x3", 2 1/2" square, 3"x3" and 3"x4". A 3"x4" has twice the opening of a 2"x3", so pair it with every 6" run; our counter rule is a downspout roughly every 30 to 40 feet of trough. Where a downspout is not connected to a sewer, the Ontario Building Code asks for an extension that carries the water away from the building without eroding the soil.
Frequently Asked Questions
What is the difference between an eavestrough and a gutter?
In Canada, the terms are used interchangeably. Eavestrough is the traditional Canadian term; American literature typically uses gutter. Same products, different words - we use eavestrough because that's what most Canadian contractors and homeowners search for.
What eavestrough size do I need - 5" or 6"?
A 5" K-style eavestrough suits most bungalows and small two-storey roof planes. Step up to 6" on large planes, steep pitches, or valleys that dump two roof faces into one run, because a 6" trough carries noticeably more water, and pair every 6" run with a 3"x4" downspout. Our eavestrough guide walks the decision.
How long do aluminum eavestroughs last?
Kaycan does not publish a service life or a warranty term for its aluminum rainware in the material we hold, so we do not quote one; ask for the warranty details with your quote. What shortens a run's life is mostly in the installer's hands: hangers spaced so wide the trough sags and ponds, joints and end caps left unsealed, and a trough left full of debris through the winter.
Do you supply eavestrough for commercial projects?
Yes. We stock 6" aluminum K-style eavestrough and the matching downspouts, elbows and outlets, which covers most low-rise commercial and agricultural work. We do not stock steel eavestrough or box gutter. Request a quote with your material list and quantities and we will tell you what we can and cannot supply.
What gutter guards work best in Canadian winters?
Start with the trees. Under pines and spruce, use a dual-layer guard: the Alu-Rex DoublePro, Hover Pro and Gutter Clean Pro put 7/64 in. micro-perforations over a slotted second layer, and Alu-Rex gives them a lifetime clog-free warranty that includes coniferous areas. The single-layer Gutter Clean System and T-Rex carry a 25-year prorated clog-free warranty that excludes conifers. We carry gutter protection from both Kaycan and Alu-Rex, and our gutter guards guide charts the warranty schedule and drainage figures.
Can I order by the piece or do I need to buy in bundles?
We sell to contractors and homeowners on a quote basis, in project-specific quantities. Submit a quote request with your material list and we'll respond with pricing and availability.
What downspout size pairs with 5" and 6" eavestrough?
Kaycan's aluminum downspouts come in 2"x3", 2 1/2" square, 3"x3" and 3"x4". Pair every 6" K-style run with 3"x4", which has twice the opening of a 2"x3", and match the drop outlet to the downspout. The vinyl systems take their own downspouts: K-Snap in square, round or ribbed, U-Snap in ribbed, and the Classic half-round in square or round.
