Blown-In Attic Insulation in Ottawa
Attic insulation upgrades that cut heat loss, even out room temperatures and help stop ice dams
Attic Insulation Contractor for Ottawa Homes
Attic insulation in Ottawa does two jobs. It keeps heat in the house through long winters, and it keeps the roof deck cold so snow does not melt and refreeze into ice dams. Vanity Roofing installs blown-in attic insulation for homeowners across Ottawa and the Ottawa Valley, from city homes in Nepean and Barrhaven out to Almonte and Carleton Place.
Blown-in insulation fills every gap between joists, around wiring and over the top plates where heat escapes, which batts often miss. Because we are roofers, we look at the whole attic, including ventilation, baffles and bathroom fan venting, so the insulation and the roof work together.
Ontario homeowners may also qualify for home energy rebates that help cover the cost of an insulation upgrade.
Signs Your Attic Needs More Insulation
High heating bills, cold rooms upstairs and big icicles every winter usually point to the attic. A proper insulation upgrade gives you
- Lower heating and cooling costs
- More even temperatures from room to room
- Fewer ice dams and less risk of roof damage
- Less frost and condensation in the attic when paired with good ventilation
- A quieter, more comfortable home through Ottawa winters and summers
Insulation works best with good airflow, so we always check your roof ventilation as part of an attic upgrade. Together they keep heat in the house and help prevent ice dams in the winter.
Why Choose Vanity Roofing for Attic Insulation
Most of our insulation work is in attics, where it does the most good, and we can also look at other areas of the home where heat is escaping.

How an Attic Insulation Upgrade Works
Detailed Evaluation
We measure the attic and find the gaps, thin spots and air leaks
Custom Solution
We recommend the insulation depth and R-value that suits your home and Ottawa's climate
Professional Installation

Quality Verification
We confirm even coverage, clear vents and a clean hatch before we leave
Why Choose Blown-In Attic Insulation
Blown-in insulation is loose-fill material, usually fibreglass or cellulose, blown into the attic with a hose. It settles into every corner, around joists, wiring and vent pipes, and builds a continuous layer with far fewer gaps than batts or rolls.
Many older Ottawa homes have thin or settled insulation from when they were built. Topping it up to current recommended levels for our climate, often R-50 or higher in an attic, makes a real difference to comfort and energy use.
- Even coverage around joists, vents and other obstacles
- Fills small gaps that batts and rolls cannot reach
- Builds up to the R-value your attic needs
- Cuts heat loss through the ceiling and roof
- Installed from the attic hatch with no mess in your living space

- A full attic inspection before any work starts
