Spring Eavestrough Inspection in Waterloo Region: What Winter Did to Your System

Freeze-thaw cycles run from roughly November to April in Waterloo Region, and your eavestroughs take every one of them. This spring inspection guide shows which winter injuries to look for, how to spot each one, and which need attention before the next rain.

Pick the right week to look

Start once the snow has left the roof edge and the ground has firmed up. Thawing soil is soft, and a ladder foot can sink or slide in it. In this part of Ontario that usually means April, but let the ground decide, not the date.

If you can, inspect before the heavier spring rains. A leak found in a dry week is easier to fix than one discovered during a downpour. Make your first pass from the ground with binoculars or a phone zoom, and climb only if the ground is firm, the ladder is set properly and no wires are close.

Bring a short kit: binoculars or a phone with good zoom, painter's tape to mark problem spots on the wall, a notepad and a garden hose for the flow test. The tape lets a repairer find each spot without a second walk-around.

Six suspects winter leaves behind

1. A bent front lip or sagging run. Ice load and sliding snow are the usual causes. Sight along the trough from each end, and look for water pooling in the dips after rain.
2. Hangers pulled out of line. Heavy ice tugs the trough forward. Look for a gap between the back of the trough and the fascia, or hanger heads standing proud.
3. A split downspout seam or separated elbow. Water that froze inside expanded and forced the joint open. Run a hose down each downspout and watch every joint for spray.
4. Failed sealant at seams and end caps. Repeated expansion and contraction wears it out. Look for drips, or dirty tracks running down the wall under a joint.
5. Displaced extensions and splash blocks. Snow piles, shovels and frost push them around. Confirm each one still points water away from the house.
6. Roof-edge damage. Check that the shingles at the eave are flat and that the edge still lets water drop into the trough and not behind it.

A dent is mostly cosmetic. A dip is not, because standing water freezes and pulls on the hangers all over again next winter. Put sagging ahead of surface damage on your list.

Also look inside. Ceiling stains near an exterior wall can point to ice damming last winter. For a fuller list of warning signs, see how to spot gutter damage.

What the meltwater did on the ground

The ground under each downspout records how water behaved all winter. Look for a washed-out channel, a splash block that has sunk or tilted, and puddles that stay for more than a day after rain.

Then check the soil at the foundation. It should still fall away from the wall. Frost can shift soil and pavers, and a small dip against the house sends every downspout's water straight to the footing. The grading guide explains how the slope should look and how to correct a low spot.

Triage: what cannot wait and what can

• Act now: a run pulling away from the house, a downspout dumping water against a wall or a basement window well, or a damaged section that spills over an entry.
• Fix this season: loose hangers, leaking seams, dents that hold water, and sags that pond.
• Photograph and watch: cosmetic dents, faded paint and light surface rust. Take a photo and compare it in the fall.

Fresh photos also give you a dated baseline. If a problem grows over a season, the pictures show it. The snow and ice damage prevention guide explains how to head off next winter's version.

Sequence your spring jobs

Inspect first, repair second, clean third. Clean once the maple seed pods and oak catkins have dropped, usually late May into June, so you are not paying to clear troughs that refill within days. The exception is a trough that is already full when you inspect. Clear it at once, then plan a second look after the seed drop.

Small repairs, such as resealing a seam or adding a hanger, go best in a dry, mild spell, because sealant needs clean, dry metal to bond.
