A well-ventilated attic can be the solution to a lot of potential headaches. There are some clues to look for to see if you have a ventilation problem, though.
Your roof’s surface should remain cool during the winter. Snow will melt on a warm roof, causing it to trickle to the colder edges where it will refreeze. This is called an ice dam, and it is problematic as it traps moisture behind it where it will seep under your shingles and in to your house. If you notice an ice dam forming on your roof, or if you notice mildew or rotten shingles that result from one, you may have a ventilation problem.
These problems should be visible from your yard with a pair of binoculars. Shingles are often wet and slippery, especially in the winter, so we recommend staying safely on the ground.
If you aren’t feeling like going outside, you can also check your attic for common warning signs. Insufficient attic ventilation will cause moisture to build up under your roof leading to some serious problems. Look out for blackened or water-stained wood. This signifies mold or rot, which can be dangerous. If you see that the insulation is matted down or soggy, or if you notice rust developing on nails or other metal surfaces, this indicates too much moisture. In the winter, you can also check for frost or ice.
Poor ventilation can increase the cost of cooling your home in the summer, as warm air becomes trapped inside. A common misconception is that increased ventilation will also increase heating costs. If the vents are properly installed and the attic well insulated, this won’t be being the case.
In fact, the cost of many of these problems can be astronomical. Considering that, many are surprised by the relatively inexpensive price tag associated with installing air vents.
