Roofing Ventilation: What Welland Homeowners Need to Know

The ventilation in the roofing system of your Welland home is vital to ensure that your roof can dissipate heat released by the sun shining on it. It's also crucial for your home's energy efficiency. 

Heat enters your house through the roof then the ceiling, which leads to higher cooling costs in the summertime. In the wintertime, warm air will escape from your home because of inadequate ventilation. 

This means that you'll have to crank up the thermostat and run your furnace for a longer period of time. You can go a long way in preventing these two scenarios by having a roof ventilation system installed in your roofing system.

Here are some questions and answers about ventilation of the roofing system in your Welland home:

What does a roof ventilation system do?

A roof ventilation system works together with your home's central air conditioning and heating systems to ensure that you get excellent indoor climate control. Air in your attic can be very hot or very cold due to the temperature differences between indoors and outdoors. 

It is not only uncomfortable, but it will also result in gaps in your insulation. This will increase the heating and cooling costs in your home. 

A roof ventilation system enables you to control the temperature in your attic, which inevitably can also affect the temperature inside your house.

What happens when there is no appropriate ventilation?

When there are no vents or too few vents, warm air stays inside your attic space and doesn't escape into the atmosphere. This leads to overheated rooms below because of trapped air and causes poor insulation due to lack of circulation.

If you have a closed-up attic space without appropriate rooftop ventilation, consider having more holes or vents cut into the plywood before installing new insulation or finished flooring materials. Otherwise, you will pay significantly more on heating bills each month.

Roof ventilation is critical to ensure that your roof can dissipate heat released by the sun shining on it. It's also crucial for your home's energy efficiency. 

What do I need to know about adding insulation in my home?

Homes that are under-insulated are the most affected by poor roof ventilation. Without proper ventilation, your home's ability to retain heat becomes compromised, leading to higher cooling costs in the summertime. A tight building envelope plays a large part in how much it will cost you to heat and cool your home.

If you have an older home, it is more likely to need additional insulation in the roofing system. This can be done while a new roof is being installed or afterward if you decide on a roof replacement.

How do I know if my home needs extra insulation?

There are a number of ways to determine how much insulation is needed in your home. In most cases, it will be obvious which areas require more insulation when you add up the total R-value in your attic. 

The R-value refers to the thermal resistance of a material and measures its ability to resist or impede heat flow. The R-value is based on the thickness of the material used. The higher its R-value number, the more effective it will be in your roofing system.

Does choosing the right material matter?

Choosing the right material for your insulation is vital. If you choose materials that cannot withstand changes in temperature, they will deteriorate quickly. This is due to high levels of humidity or heat inside the home.

Fiberglass, cellulose fiber, or mineral wool are some of the best choices because they can resist wet conditions. They do well in extreme temperatures.

How does it affect your electric bill?

How do I work with the contractor?

When shopping around for a new roof or installing one on your home, ask how the contractor can increase roof ventilation. 

Remember to have adequate insulation installed in your home if you haven't already. You will likely need to replace the old insulation, though it's possible that using blown-in cellulose insulation over old fiberglass batts is an option (if there are no signs of water damage or mold).

Because warmer air rises, it escapes through the roof only if the space below has adequate ventilation. This may mean cutting new vents in the roof. Let your roofing contractor guide you.
