Most Calgary attics are under-insulated. If your energy bills are climbing or certain rooms never reach the right temperature, your attic is usually where you're losing heat. Epic has been solving this problem for Calgary homeowners since 2001.
Calgary winters are hard on homes. When your attic isn't insulated properly, heat escapes through the ceiling instead of staying where it belongs, and your furnace runs longer and harder to make up for it. Over a cold winter season, that adds up.
It's not just about comfort or energy bills, either. Poor insulation paired with inadequate ventilation creates the conditions for ice dams along the roofline, condensation on the underside of the roof deck, and moisture buildup that leads to ceiling stains and, eventually, structural damage. We see these problems regularly as a roofing company, and they almost always trace back to the attic.
The good news is that a proper insulation upgrade, done once and done right, addresses all of it. Most Calgary homeowners see a noticeable difference in comfort within the first season.

Some rooms never quite reach the right temperature, your heating bills have crept up, or you've noticed ice building up along the roofline in winter. These are all signs your attic insulation may be underperforming. A free inspection will confirm your current R-value and whether an upgrade makes sense.
For most Calgary homes, yes. If your attic is below R-50, you're losing heat through the ceiling every winter. Most homeowners see a noticeable drop in heating costs within the first season. Combined with better comfort and reduced moisture risk, it's one of the more straightforward home improvements to justify.
The most common option for existing Calgary homes is blown-in fiberglass or cellulose, which brings the attic up to R-50 quickly and without major disruption. For air sealing specific areas, we use closed-cell spray foam. The right material depends on your attic's current state, which is why we assess before we quote.
The most common attic insulation upgrade for Calgary homes. Loose-fill fiberglass or cellulose is blown in to bring your attic up to R-50, the current Alberta building standard. It's fast, effective, and doesn't require tearing up ceilings or walls. Most jobs are done in a day.

Used for air sealing, rim joists, and areas where blown-in insulation isn't the right fit. Closed-cell spray foam creates an air and vapour barrier in one application. It costs more than blown-in, but it's the right call for specific parts of the attic, especially in older homes with more complex layouts.

Older homes sometimes have insulation that's settled, moisture-damaged, or contaminated by pests. When that's the case, we remove the old material before installing new. Starting clean ensures the new insulation performs as designed and doesn't trap existing problems.
We'll come out, take a look at what you're working with, and give you a straight answer on what needs to happen and what it will cost. Most assessments take less than 30 minutes.

Common signs include uneven temperatures between floors, high heating or cooling bills, ice dams forming along the roofline in winter, and drafts near the ceiling. A quick attic inspection will confirm your current R-value and whether an upgrade makes sense.
Alberta's current building code recommends R-50 for attic insulation in most residential applications. Many older Calgary homes were built to lower standards and have R-20 to R-30. Bringing them up to R-50 typically improves comfort and energy use.
Blown-in fibreglass or cellulose is the most common and cost-effective option for existing homes. Both perform well in Calgary's climate and can be installed without major disruption. Spray foam is a better fit for air sealing specific areas or homes with more complex attic layouts.
Most standard blown-in insulation jobs in Calgary take a single day. Larger homes, projects that require insulation removal first, or jobs with significant air sealing work may take longer. We'll give you a realistic timeline during your free assessment.
Done correctly, attic insulation upgrades do not void roofing warranties. In fact, proper insulation and ventilation can extend your roof's life by reducing thermal stress and preventing ice dam conditions. As an Owens Corning Platinum Contractor, we make sure all insulation and ventilation work is compatible with your roofing system.
Yes. Poor insulation paired with inadequate ventilation is a leading cause of condensation buildup in Calgary attics, which shows up as ceiling stains or moisture on the underside of the roof deck. Addressing the insulation and ventilation together fixes the root cause, not just the symptom.
