Attic insulation inspections in Vancouver

The attic is usually the cheapest big energy fix in a house, and the inspection decides how to do it: how much insulation is there, where air leaks through the ceiling, and whether anything up there must not be disturbed.

What inspections find in Vancouver attics

Of Vancouver's 115,455 houses (single-detached, semi-detached, row houses and duplexes), 31% were built before 1961 and 62% before 1991, according to the 2021 Census. Attics in older houses commonly have a fraction of today's recommended insulation, and top-ups done over the years often buried air leaks instead of sealing them first.

Vancouver gets about 2,768 heating degree-days a year, a measure of how much heating its climate needs, and its winter design temperature, the cold day heating systems are sized for, is −4.4°C. Those figures come from the climate data for Vancouver International in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. That's the 7th-lowest heating demand of the 70 cities we cover. With winters this mild, extra attic insulation pays back more slowly on heating alone; keeping upstairs rooms cooler in summer and stopping damp air reaching the roof deck count too.

Vermiculite. Loose, pebbly, grey-brown or silver-gold insulation may contain asbestos. Health Canada's advice is not to disturb it; have it sampled before any attic work. Asbestos and vermiculite testing in Vancouver

The right order for the work

  • Seal the air leaks first: top plates, pot lights, plumbing stacks, the hatch.
  • Fix ventilation baffles so new insulation doesn't block soffit vents.
  • Then top up the insulation. Burying unsealed leaks under new insulation wastes much of the benefit.

What this means in Vancouver’s climate

Mild, wet winters and summer heat waves: fix moisture first, then cooling and heat pumps.

Why it matters here: Checks insulation depth and looks for damp or stained roof sheathing, a sign of roof leaks or warm, moist air escaping into the attic.

Best timing: During or just after the October-to-March rainy season, when wetting is at its peak.

  • Fix moisture before tightening up. Heavy winter rain soaks walls and roofs here. Insulation makes outer layers colder and slower to dry, so fix leaks, condensation and mould first, or upgrades can trap water. Ask: Ask the registered energy advisor to note stains, damp spots and roof or window leaks, and to check that bath and kitchen fans vent outdoors.
  • Seal air leaks, then top up the attic. NRCan calls air sealing the most important retrofit. Pair it with attic insulation: today's new-home minimum here is about R-39, a useful target for older attics. Ask: Ask for a blower door test before and after sealing, so you can see the drop in ACH50.

Attic insulation inspection in Vancouver: common questions

How much attic insulation should a Vancouver house have?

Advisors commonly target around R-50 to R-60 in attics. Your EnerGuide report gives the recommendation for your house.

Can I top up the insulation myself?

Only after the air leaks are sealed and you've confirmed there is no vermiculite. The inspection tells you both.

Does attic insulation help in summer?

Yes. Sealing and insulating the attic floor slows the heat that builds up under the roof from reaching the rooms below, so upstairs bedrooms stay cooler. Keep the soffit vents clear with baffles so the attic can still dry out in damp months.
