Roof Attic Ventilation Problems

An unexplained uptick in your household heating and cooling bills which can happen if your attic insulation gets wet and loses its effectiveness.

Roof attic ventilation problems.

Vents come in various styles. The risk reward for having no ventilation or poor ventilation along with the negligible cost of installing a good working. For the best results place roof ventilation near the roof s peak and soffit vents in the eaves. Not only does ventilation help maintain the quality of your roof but it also helps to prevent ice damming in the winter.

Here are some subtle and some not so subtle things to watch out for. If you don t know how your roof vents work or if you re unsure about your attic ventilation in general you should talk to a roof inspector about your current system and any inherent weaknesses that may be at work. The wind which blows over your roof will help to draw the hot moist air out of your attic when roof ridge vents are installed correctly. An inadequate attic ventilation system can cause a variety of problems that manifest themselves in different ways.

Air flows in through the soffit vents and out through the roof vents. Grab a flashlight and inspect your attic during the winter. Soffit vents tend to be the most effective way to ventilate your attic. We can address this by getting more specific which is to say we need to discuss the most common problems that occur with the roof vents themselves.

We discussed the most common issues with roof ventilation in the recent section. This happens because of the change in air pressure. A contiguous air vent in conjunction with soffit vents are recommended for encouraging the best natural air flow. It is still a huge risk even if your top cap is covering most of the gap between vents if you are in an area that receives snow at any time.

Without proper ventilation moisture from everyday activities such as showering washing laundry and washing dishes rises to the attic and slowly collects there. If you see dampness or frost you need better roof ventilation and some attic vents. This can lead to a number of serious and expensive problems. Improperly spacing your vents can also lead to some serious leaking.

Excess heat and moisture cause roof decking to dry rot and shorten the life of shingles and underlayment. But what we failed to do is explore the reasons why ventilation issues occur in the first place.
