professional attic insulation service Toronto homeowners can trust does more than add material to a space above the ceiling. It improves comfort, lowers heating and cooling costs and helps protect the roof above from moisture damage. Flat Roofs Toronto offers one-call attic services, from inspecting existing insulation and removing old material to installing new insulation, air sealing and related attic work.

Signs You Need Upgraded Insulation

  • An older home. Insulation that has not been upgraded in more than 20 years is often insufficient, and some older materials contain hazardous elements.
  • Mould or water damage. Water is the biggest enemy of insulation, and a leaking roof usually means damaged insulation.
  • Pests. Droppings, dead animals and lingering odours mean it is time for removal and replacement.
  • High utility bills. Poor insulation lets conditioned air escape.
  • Icicles on eavestroughs. A warm attic melts snow and refreezes at the edge, which can lead to moisture and rotting wood.

Types of Attic Insulation

Spray foam is polyurethane sprayed directly into place. Open-cell foam is less costly and forms an air barrier, while closed-cell foam is denser and also provides a vapour barrier. Batt insulation is fiberglass installed between joists and is an inexpensive, easy option for unfinished spaces. Blown-in insulation uses cellulose or fiberglass, with cellulose offering a slightly higher R-value but a tendency to settle over time. Both are built to resist fire. Rigid foam panels are another option for renovations and new builds.

Understanding R-Value

R-value measures resistance to heat flow, and a higher number means better performance. It depends on the density of the material rather than thickness alone. Toronto-area homes generally aim for R-50 to R-60. Newer homes may only need to add R-19, homes around 20 to 25 years old may need R-30 to R-38, and homes older than 25 years often need R-50 to R-60.

Ventilation and Air Sealing

Insulation performs best when air leaks are sealed first and the attic can breathe. Proper airflow prevents moisture buildup that can compromise both insulation and structure. The team can also handle attic cleaning, insulation removal, air duct replacement, rodent proofing and attic access improvements such as drop-down stairs or door repairs.

What It Costs

Typical attic insulation projects average roughly $1,500 to $3,500, with per-square-foot rates ranging from about $1.00 to $4.50. Inspection, old-material removal and air sealing add to the total, which is why a free quote is useful.
