The Benefits of Proper Attic Insulation for Homes in the Greater Toronto Area
For the significant majority of Toronto homeowners, the least used area of their home is the space found directly between the ceiling of the top floor and the pitched roof; that is, the Attic Insulation. This space is awkwardly-shaped and can be difficult to access, and while some homeowners might use this area for storage purposes, it is quite possible that most have never actually looked in their attic during the time that they have lived in the home.
In this latter situation, it is often assumed, with a high degree of accuracy, that the attic basically consists of exposed rafters with some type and thickness of insulation lining the gaps in-between. And though an attic may be thought to be a dark and dingy void, the insulation that it houses can have a substantial impact on energy use and the prevention of roof repairs for Toronto homeowners.
Attic insulation plays an important role in reducing heat transfer or the process by which air naturally moves or travels from warm areas to cold areas. The insulation serves as a barrier in this case, inhibiting warm air from escaping the home via the roof during the cold weather months and similarly preventing hot air from entering the home during the warmer/summer months; thus homeowners can set their thermostats to more moderate temperatures throughout the year and keep utility costs at a more manageable level.
In addition to its positive influence on energy efficiency, attic insulation can help Toronto and area homeowners avoid the unnecessary and unwanted expense of repairing a leaky roof or other types of roof repairs. How? By preventing such adverse situations as:
- Mold and mildew growth
- Condensation inside the home
- The formation of ice dams in winter
- Deterioration of/damage to the shingles
- Expansion and contraction of the roof decking
A question then becomes: what is a proper or adequate amount of attic insulation for the climate in Toronto? The answer first requires a brief examination of a term often used to describe insulation or other types of insulating materials; R-value. Essentially, R-value is a measure of the resistance of any insulation to heat flow; accordingly, insulation with a higher R-value or rating will naturally have better protective or blocking properties.
With this in mind, a recommended/acceptable R-value for attic insulation in Toronto-area homes would be in the range of R-50 to R-60, depending on the type of roof and the age of the home.
A Comprehensive Inspection Can Assess the Efficiency of Your Attic Insulation
There are several factors that can have an impact on attic insulation R-values, such as:
- Type of insulation – loose, batts, foam
- The density or thickness of the insulation
- Installation – was it done in the proper fashion?
However, it is quite likely that many homeowners would not be able to confirm most/all of the above nor would they be aware of the precise R-value of their attic insulation; yet, if they are experiencing one or more of the following circumstances, it may be a sign that their insulation is below acceptable levels:
- Abnormally high utility bills
- Ceilings hot or cold to the touch
- An ineffective air conditioning system
- Mold on ceilings or in wall-ceiling corners
- Uncomfortable temperatures on the upper story
Consequently, if homeowners suspect or have evidence that their attic insulation is not performing to acceptable standards, they might want to contact an experienced roofing company, such as Avenue Road Roofing in Toronto, to conduct a detailed inspection and determine whether an insulation upgrade or perhaps a full replacement may be required.
Furthermore, depending on the extent and duration of the insulation problem/deficiency, this inspection can identify and roof repairs that may be required, either to the shingles, the roof deck, or the drainage/gutter system; in the latter instance, this may result from ice dam formation subsequent to ineffective attic insulation over the winter months.
