Insufficient Ventilation And What It Means For Your Roof

When your roof does not have proper or sufficient ventilation installed, it can lead to a veritable laundry list of problems that damage your roof. You can avoid some major home damage as well as avoiding spending a lot of coin on roof renovations by making sure that your roof is properly ventilated. Read this article to learn more. 

Problems You May Encounter

Blistered shingles are among the most common of problems you will face if you do not have adequate ventilation flowing through your roof. Blistered shingles occur when there is a significant amount of air pressure that exists underneath your roof's shingles. Without a ventilation system, or proper ventilation system, the air cannot escape from your roof. This build up of air pressure leads to your shingles blistering and eventually cracking and breaking.

Improper roof ventilation also lessens the integrity of the roof. The excess moisture from the humidity in the air that can't escape worms its way underneath your shingles. The moisture begins to dissolve adhesive, warps shingles and the wood the shingles are attached to, and generally lowers the integrity of your roof. This can make your roof a dangerous place to walk on, as well more susceptible to things like wind damage.

Ice dams are a problem that roofs without proper ventilation will face during winter months. Without a properly vented roof, moisture in the air causes a series of icicles to grow and hang from your roof. The ice build up blocks water from properly sliding down your roof. Instead, it starts building up further, creating an icy dam that eventually starts to hold moisture on your roof. Damage from ice dams include gutters breaking from the weight of the ice, standing water causing mold or mildew to grow or breaking down the shingles, and built-up water pooling into your home .

Ice dams are not the only problem you will encounter in the winter months if you do not have adequate ventilation. The appearance of frost in the attic due to moisture forming in the stale air that cannot escape is a common problem among roofs without adequate ventilation.

One Solution To Insufficient Ventilation

The most common, and perhaps best solution, to making sure that your roof is properly ventilated is installing mixed exhaust vents.

A mixed exhaust ventilation system consists of two types of exhausts that will allow for maximum ventilation to occur. These are generally referred to as high vents and low vents. The high vents function such that they act as exhaust vents. The exhaust vents will essentially make sure that air is escaping your house, and particularly the area around your roof, so as to not create pockets of stale air under your shingles or in your attic.

On the other hand, the low vents function as intake vents. They replace the stale air that was resting in your attic and just above your uppermost ceiling with fresh air. This is so the airflow can reach the house without ultimately becoming stale. This is, perhaps, the most sufficient way to get air flow throughout your house while simultaneously getting rid of the stale air that is the cause of so many problems in the winter time, as well as being a primary cause of why your house may become so humid.

If you have noticed these problems in your home, or are just aware that your roof does not have a proper ventilation system, take the proper steps to rectify the situation. You can hire a professional that deals with roof repair to first rectify the damage done by improper ventilation and then install the proper ventilation for you. Although the problem of insufficient ventilation may seem benign, it can cause big issues in the long run if not dealt with.
