Tips for how to safeguard the vents on your roof

Dec 14

The truth is that your roof's ventilation system is probably not something you consider often. It's not likely to break or fail to function until it breaks.

It's an integral aspect of daily life in your house. A properly-designed ventilation system can make an enormous difference to the lifespan of your roof, your satisfaction, health, future home repair costs, and the cost of heating and cooling. This can bring a number of advantages for something that tends to be a matter of thought.

In conclusion, let's give some attention to ventilation, how it functions and why it is important, and how you can best take care of the ventilation system.

How Attic Ventilation Work

Effective ventilation in an attic that's not completed usually comprises intake vents that are low down with the soffits and exhaust vents higher up the peak of the roof ridge. This ensures continuous airflow throughout the attic. The cooler, outside air is pulled in through the vents on the soffit. In the meantime, humid, warm air that is pushed to higher points (hot air rises, while cold airdrops) is released through vents located on the roof's ridge. This results in continuous circulation, which is important for many reasons.

Why Roof Ventilation is Important

Proper ventilation in the attic allows you to eliminate the accumulation of heat and moisture that can otherwise wreak havoc on your home. In both cold and hot climates, the buildup of moisture and heat can create problems. A region with hot summers or cold winters as do most Canadian homeowners may suffer from both.

If it's hot outside the sun's heat pounding down the roof could increase the temperature in the attic. Exposure to this excessive heat could cause the roof to warp as well as cause distortion and premature aging of the shingles. The floor of the attic must also be considered. If it's not properly sealed and evenly distributed, the heat could get into the living space and cause it to become harder and more expensive to maintain comfort. You will see a rise in your energy costs because your AC is forced to work twice as hard.

The roof deck's underside is heated by warm air from the living area that is heated below when temperatures drop below freezing in winter. As the roof deck gets warmer and the roof deck warms, the lower layer of accumulated snow on the roof starts to melt, and water begins to run down the roof. The runoff is ice when it gets to the colder outer edges. When this happens often and the dam is formed, it will form on the eaves, preventing the flow of runoff. At some point, the water will have nowhere else to go, which is why it backs up under the shingles.

Let's discuss the H-word that is humidity. The outside air or the living area enters your attic. It will condense into the form of a liquid upon contact with cooler surfaces. Over time, that moisture may cause the deterioration of the roof's system as well as the interior structures, or destroy the insulation of your attic. In a hot attic, it can cause the growth of the common mildew and mold. This can put additional stress on the cooling system in your home. Your pocket suffers...again.

Signs Of Improper Ventilation

A poor attic ventilation system may cause problems that manifest the same way in different ways.

A mysterious increase in your home's heating and cooling bills, which could be the result of attic insulation being damp and loses its effectiveness.

You'll notice a buildup of ice at the edge of your roof during the winter months.

A wavy or curved roofline and shingles with ripples caused by the warping of decking that has been damaged by moisture underneath.

The attic is susceptible to rust and corrosion, for example, lighting fixtures, electrical cabinets, nail heads, and electrical boxes.

Water staining, dampness, or frost that has accumulated on the attic side of your roof sheathing.

The growth of mold in your attic may cause an increase in symptoms and respiratory problems in your family.
