Do gutter guards actually work? An honest answer from the people who clean gutters.

Fair warning before you read this: we clean gutters for a living, so you would expect us to tell you guards are a waste of money.

We are not going to. Good guards on the right house are worth it. But the pitch you get at the home show, the one where you never think about your gutters again, is not true, and believing it is how people end up with a worse problem than the one they were solving.

What guards actually do

A gutter guard is a screen, mesh or cover that keeps leaves out of the trough while letting water in. On a Simcoe County house with maples or oaks over it, a decent one takes you from clearing twice a year to clearing every second or third year.

That is a real saving. It is not nothing.

What it does not do is stop debris getting in entirely. Shingle grit, pine needles, seed pods and the fine silt that comes off asphalt all pass straight through most guards or build up on top of them. That material still ends up in the trough, and it still packs down and blocks a downspout eventually. It just takes longer.

The three kinds, and how they hold up here

Plastic mesh and clip-in screens. Cheapest, and the ones that go wrong most often around here. They sag, pop out under snow load, and go brittle after a couple of winters. We pull a lot of them out of gutters in the spring, usually in pieces.

Metal mesh, properly fastened. The middle option and the one that makes sense on most houses. Fine enough to stop leaves, robust enough to survive a winter off the bay. Needs the mesh brushed off occasionally, because leaves that cannot get in will sit on top instead.

Solid reverse-curve covers. These are the expensive ones with the sales pitch. Water is meant to wrap around the curve into the gutter while debris slides off. They work in moderate rain. In a hard Simcoe downpour, and in the meltwater surge we get in March, water overshoots the curve and runs straight off the roof past the gutter entirely. You end up with a dry gutter and a wet foundation, which is the exact thing gutters exist to prevent.

The problem with never looking

Here is the part that costs money.

Guards do not just keep leaves out. They keep you out. Once a house has covers on it, most people stop checking, and nobody notices the downspout that has been slowly plugging for three years or the section of fascia that has started to rot behind the trough.

We have opened up guarded gutters in Orillia and Oro-Medonte that had not been touched since installation and found them packed solid with a compost of needles and shingle grit, water backing up under the drip edge, and rot in the fascia board underneath. The guards were doing their job. The homeowner had simply been told they would never need to look again.

A blocked gutter you can see is a $200 problem. A blocked gutter behind a cover that nobody has checked in five years turns into fascia and soffit work, and that is thousands.

Ice is the Simcoe-specific bit

Most guard marketing is written for somewhere warmer than here.

When a guarded gutter freezes, the ice forms on top of the cover as well as inside the trough, and the cover holds it there. That adds weight along the roof edge and gives meltwater somewhere to sit and refreeze, which is how ice dams start. Dams push water back up under the shingles, and that leak shows up on a bedroom ceiling in February.

Guards do not cause ice dams on their own. Poor attic insulation does that. But a guarded gutter that has not been cleared makes them worse, and a solid cover makes them harder to clear once they have formed.

So should you get them?

Worth it if: you have heavy tree cover, a two or three storey house where getting up there is genuinely awkward, and you will accept that you are reducing the frequency rather than ending it.

Skip it if: you have an open lot with little overhang, or a bungalow where clearing the gutters is a straightforward job. On those houses the guards cost more over ten years than the cleanings they replace.

Whatever you choose: get the system looked at every second or third year. Not scrubbed out necessarily, just opened and checked. That is the difference between guards saving you money and guards hiding a problem until it is expensive.

What we do

We do not sell or install gutter guards. We clean gutters, guarded or not, and we will tell you honestly what we find under yours.

If you already have covers and cannot remember the last time anyone looked, that is worth a visit. We take a section off, check the trough and the fascia behind it, clear whatever is in there, flush the downspouts, and put it all back. You get photos of what was under there, which for most people is the first time they have actually seen it.
