At Roof Repair Malaysia Roofers, we’re here to talk about a subject that could significantly impact your comfort and your wallet: attic insulation and weatherizing. Believe it or not, these measures can reduce your energy bills by up to 40%. Surprising, right? Most homeowners aren’t aware that over half of their home’s heat slips away through the roof. By sealing air leaks and properly insulating the attic, you can lower heating costs and keep your indoor spaces comfortable.

Let’s explore the essential benefits of attic insulation. According to the Canada Mortgage and Housing Corporation (CMHC), a well-insulated home is akin to wearing the right attire for the weather—it protects your house from external temperature variations, moisture, and mold. Here are three key points to understand about attic insulation:

First, attic insulation shields your home from top to bottom. Since the attic occupies the highest point of your house, it’s particularly vulnerable to temperature fluctuations. To optimize energy efficiency, you should have the entire house insulated, from the roof down to the foundation.

Second, it’s an economical way to weatherproof your home. During winter, your attic becomes the coldest part of your house, and during summer, it becomes the hottest. Proper attic insulation reduces heat loss and gain, significantly lowering your heating and cooling expenses.

Third, it safeguards your home from ice dams and mold growth, both of which often lead to expensive roof repairs. Inadequate insulation and ventilation cause warm, moist air to accumulate in the attic, creating conditions conducive to mold. This warm air also melts roof snow, forming puddles that refreeze as ice dams when temperatures drop. Ice dams are a common culprit behind winter roof leaks.

Now, you might be wondering if foam spray insulation is the best solution. Insulation is rated based on its R-value, which indicates its resistance to heat loss. The higher the R-value, the better the insulation’s performance. Our roofing experts will conduct a thorough assessment of your roof and attic to recommend the most suitable insulation. Our high-quality foam insulation offers uniform sealing of gaps and air leaks.

Before adding attic insulation, it’s crucial to address air leaks. These leaks can be found in various parts of your home, and, when combined, they’re akin to leaving a window open during the winter, as per the Environmental Protection Agency (EPA). Both the EPA and CMHC recommend sealing air leaks before insulating the attic. Focus on areas around windows, doors, pipes, vent stacks, flues, chimneys, electrical fixtures, heating and air conditioning ducts, access hatches, staircases, and more.
