Seasonal Eavestrough Maintenance Guide for Southern Ontario Homeowners

Eavestroughs work in every season here, and each season asks for something different. This guide walks through a full year of tasks, from the spring thaw to winter watching, so the right job happens at the right time.

Spring: after the thaw, before the seeds

April is for finding out what winter did. Once the roof edge is clear of snow, walk the house with binoculars or a phone zoom, and look for sagging runs, gaps behind the trough and split downspouts. Our spring exterior maintenance guide covers the rest of the house.

• Check the ground as well: splash blocks that heaved or sank over winter, and low spots where meltwater pooled beside the foundation.
• Flush every downspout with a hose and check that each extension still points away from the foundation.
• Reseal open seams in a dry, mild spell, since sealant needs clean, dry metal.
• Hold the main clean until the maple seed pods and oak catkins have dropped, usually late May into June. Clear the troughs sooner only if they are already full of water.

Summer: short checks after storms

Summer needs the lightest touch. After a heavy thunderstorm, take a five-minute look from the ground for twigs, torn leaves and any trough that is still holding water the next day. Standing water in July turns into a smelly, growing mess fast.

• Check for wasp nests under the eaves before any ladder goes up. Early summer nests are small and easy to miss.
• Look for soil washed out under a downspout after a downpour. A splash block or a longer extension fixes that.
• Trim branches that scrape the roof or drop on the edge.
• Touch up scratched paint on steel troughs before rust starts.
• Use the quiet weeks to book any repairs or guard installation, so they are done before the leaves fall.

Fall: the main event

Leaf drop peaks in late October and November, when maples and oaks unload onto roofs. Book the main clean for the stretch after most leaves are down and before wet debris freezes solid. That window can be tight, so plan it in early October.

1. Clean every run and flush every downspout.
2. Repair before the cold. Tighten loose hangers and reseal seams, because freezing water will work into any gap.
3. Set the discharge. Extensions should be straight, unkinked and sloped away from the house.
4. Check the roof edge for curled shingles or a loose drip edge, and note anything for a roofer.
5. Put away the hose and clear the splash blocks so meltwater has a path.

If you clean the troughs yourself, keep to single-storey eaves, use a standoff and stay three points on the ladder. Second-storey runs are crew work.

The fall home exterior checklist shows how gutters fit into the wider job.

Winter: watch, do not chip

Winter is not maintenance season. From December to March, your job is to watch from the ground and stay out of trouble.

• Keep the snow around each downspout outlet clear, so meltwater has somewhere to go.
• Do not chip ice out of a trough or off the eave with a hammer or shovel. You will bend the metal and risk a fall.
• Keep walkways under the eaves clear of people and pets, since falling ice is dangerous.
• Note leaks or ice building at the same spot after each thaw. Photograph them, so you can act in spring.

Watch the forecast as well. Mild days followed by hard overnight frost are the risky pattern, because meltwater that cannot drain refreezes in the trough and spills over the edge.

Persistent ice dams point to heat leaking into the attic, not to the trough. The snow and ice damage prevention guide explains the cause and the options.

Two habits that make the year easier

Keep a log. A note on your phone, with dated photos, shows what you did, what you found and what changed. It shortens every future quote and makes problems obvious.

Match the schedule to your trees. A house with heavy maple and oak cover may need two cleanings a year. A house with light cover may manage on one. D&D Home Services offers gutter cleaning across Kitchener, Waterloo, Cambridge and Guelph, with free quotes confirmed in writing before work begins.
