You probably don’t think about your roof most of the time. It’s there, on top of your house, keeping the snow out and providing shelter, but so long as there are no leaks and it looks okay from the ground, you assume it’s just doing its job.

The truth is that your home is a complex system in which each separate component, from the foundation to the chimney stacks, works with the other components to create a comfortable, safe, climate-controlled environment.

This means that even if it isn’t damaged or leaking, if your roof is showing signs of age, it may be having a surprising impact on other parts of your home. Here are the two most common examples:

Temperature

You may not know it, but your roof plays a surprising role in regulating the overall temperature of your home. This is due to several factors:

  • Insulation: Warm air rises, and a poorly insulated roof will let a lot of that rising air out into the atmosphere, driving up your energy bills and leaving you with a frustratingly cold home. Around 25% of your overall heat loss happens through your roof, and this can be significantly higher if it is old or in poor repair.
  • Color: Believe it or not, the color of your shingles or roofing membrane can play a significant role in energy loss. Light-colored roofs tend to deflect heat, keeping your home cooler in the summer and making things easier for your air conditioning system.
  • Materials: Different roofing materials also impact energy retention and heat loss. Metal roofs and flat roofs often perform significantly better than houses with conventional asphalt shingles.

Many people who live in old houses are familiar with the experience of having rooms that just never seem to get warm, no matter how many space heaters you plug in. If this is your experience, you might want to call roofers in Ajax who can help you determine how your roof can help you regulate home temperature more effectively.

Ventilation

A roof doesn’t just play a role in insulating your home — it also ensures that any warm air that does escape won’t lead to water damage or the spread of mold.

No matter how good your insulation is, some warm, moist air from inside your living space will rise into the attic. When this air meets the cold air near your roof deck, condensation forms. Without proper ventilation, this condensation builds up, causing rot to set in and create perfect conditions for the spread of mold.

If you constantly have to scrape black mold out of the corners of your ceiling, chances are the main problem is insufficient ventilation. Getting an Ajax roofing company to help you cut more vents is a quick and effective solution.

In the depths of winter, everyone wants to be able to nestle down in a warm, comfortable house. But finding the perfect temperature can be impossible if your roof is aging, so if you want to make the coming months as cozy as possible, make sure your roof is doing its part.
