The importance of proper Roof Ventilation in your home

A lot of times people don’t consider doing a full inspection of the roof when purchasing a new home. It is just assumed that it was correctly designed, correctly installed and working well. Unfortunately, this is often not the case.

A proper roof ventilation system can have a huge effect on your family from an energy consumption point of view. An unventilated roof space can have a substantial warming effect on your entire house in summer making you run your air conditioners for longer at higher settings to compensate. Often there are inexpensive and simple options available to improve/repair or even install a new roof ventilation system for your home.

The other potential downside is that unventilated spaces can attract moisture from exaust fans and other common household activities. This moisture without the ability to be vented can cause quite serious damage to your internal roof cavity and shorten the life expectancy of your roof while increasing your ongoing maintenance costs. See below for some visual demonstrations of how a roof ventilation system can assist your family.

The two main functions of Roof Ventilation are Summer Venting

To clear out the hot in your roof space caused by direct sunlight. Hot air rises, so your roof vent is placed at the highest point  possible on the roof line. Outside air is drawn in while the hot air inside is expelled, leaving your roof space cooler.

and Winter Venting

To draw the moisture out of your ceiling area caused by the running of bathroom and stove exhaust fans. The condensation is simply drawn up through the roof vent shaft and expelled through the top.

Importance of Ventilation

Often homeowners don’t consider having a full inspection of the roof done before purchasing a new home. They assume that the roof was designed and installed correctly, but this is not always the case. Many homes lack proper roof ventilation and this can have a substantial effect on your energy bills and your family’s comfort.

An unventilated roof space can attract moisture from common household activities. This moisture builds up and eventually causes damage to the interior structure of the roof. This leaves the underside of your roof open to wood rot, termites, mold, pests and insects of all kinds. Many unpleasant things are attracted to warm, moist air.

The good news is that there’s a very simple solution: Roof ventilation.  Once your roof is properly ventilated, you’ll notice that your home feels much cozier. It will hold cold and hot air much better and your energy bills will go down. A properly vented ceiling space can make your roof last longer and this can be a savings of thousands of dollars over the lifetime of a roof.

It’s important to take the design of your home and roof into consideration and select a cost-effective solution that will provide optimal efficiency.  Once installed, your new venting system will accelerate the flow of air through the attic, pushing out the hot air and replacing it with cooler, fresh air.  While most home owner understands the important to remove hot air in summer, they are worried about the effects of ventilation during winter.  The important thing to understand is that dry air insulates a lot better than moist air.

Moist air comes from many sources, just from breathing, showering and cooking.  Ideally, this moist air gets directed out of your home straight into the atmosphere.  Joe has designed a unique system that allows exactly this, while keeping both the cold winter and the hot summer air out of your home.

Most homeowners say that they notice an immediate difference in the temperature throughout their home and the monthly energy bill can go down by 30%.
