Will insulating my attic stop the ice at my eaves?

Often it helps a great deal, because ice damming is usually escaping heat melting snow that then refreezes over the cold overhang. Air sealing plus even coverage to the eaves lowers the deck temperature, which is the actual cause.

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of fixing it.

Cellulose or fibreglass?

Both work when installed to depth with the ceiling sealed underneath. Cellulose is denser and resists air movement better; fibreglass is lighter and settles less. We pick based on what is already up there and tell you why.

Why is the area above my exterior walls always cold?

Geometry. The roof meets the wall at the lowest point in the attic, so there is least room exactly where it is needed most. Baffles hold insulation back from the soffit vents while letting depth carry over the wall plate.

I store things in my attic. Can I keep doing that?

Yes, but the plywood squashes the insulation beneath it to joist depth. Either the storage area gets raised on a platform above the finished depth, or it stays as a deliberately weaker zone kept small. We will not top up around it and pretend it is not there.

Should I block the vents to stop drafts?

No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.

Attic Insulation Edmonton

Blown-in attic insulation in Edmonton, sealed before it is filled

Attics in Edmonton lose depth over time — insulation settles, someone crawls through it for a wiring job, and the corners near the eaves are usually thin to begin with. A top-up is only worth doing if the baffles are clear and the ceiling below is sealed, so that is what we check before quoting.

Attic hatch insulated and weatherstripped
Baffles kept clear so the soffit vents still breathe
Blown-in loose-fill to the depth your permit specifies
Existing insulation levelled before the top-up
Depth markers left in place so the result is verifiable
Air sealing at pot lights, top plates and the attic hatch

The eaves are where it goes thin

Geometry works against you

The roof meets the wall at the lowest point in the attic, so there is least room for insulation exactly where the wall below needs it most.

What it needs

Baffles that hold the insulation back from the soffit vents while still letting depth carry out over the wall plate. Skipping them in an Edmonton attic either blocks the venting or leaves a cold band above every exterior wall.

Insulating a Edmonton attic with knob-and-tube or old wiring

Stop and check first

Some older Edmonton homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Edmonton ceilings need clearance and cannot be buried. Newer IC-rated fixtures are built to be in contact with insulation.

What we check

We identify what is installed before blowing. Where fixtures cannot be covered, they need boxing or replacing — and each one is also a significant air leak, so they are usually the first thing sealed regardless of type.

Ice damming and what the attic has to do with it

A heat problem, not a gutter problem

Ice at the eaves on an Edmonton roof usually means heat is escaping into the attic, melting snow on the upper roof, and that meltwater refreezing over the cold overhang.

Where the fix actually is

More heat tape rarely solves it. Sealing the air leaks and getting even insulation coverage right out to the eaves is what lowers the deck temperature. That is why we look at the attic when someone calls about ice, not at the roofline.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Edmonton homes a bathroom fan is frequently ducted into the attic space rather than through the roof or soffit. It dumps warm wet air straight into the coldest part of the house.

Why it matters before insulating

Burying that under fresh loose-fill hides a moisture source that will show up as frost and staining. If we find one we tell you, because it needs correcting first — insulation on top of it makes it harder to reach and harder to diagnose.

The attic hatch nobody insulates

A hole in the ceiling

An uninsulated, unsealed hatch is a direct opening between the heated house and a cold attic, and it is often the single worst detail in an otherwise good Edmonton ceiling.

Simple fix

An insulated cover with weatherstripping and a dam around the opening so blown insulation does not spill through when it is opened.
