• Curling Shingles - Curled shingles can be a sign that shingles are old and need to be replaced. But when they are less than 10 years old, it could be a sign that improper attic ventilation is occurring. As warm and humid air ventilate from the attic space, it has to escape through the cracks and gaps between your roofing substrate, underlayment and shingles. This humid air can curl shingles in between keys and where they butt together.

• Phantom Leaks - Sometimes poor attic ventilation can trap humid air from air conditioning equipment and other condensation ventilation in the attic space. Without good attic ventilation, this condensation can cause phantom roof leaks to appear in interior ceilings and walls.

• Mold - When mold or mildew is in your attic space, it’s a sure sign that a roof leak has occurred. But if your roof leak isn’t a roof leak and it’s due to humid and moist air trapped in the attic, it can be the cause of mold and mildew. When black mold is allowed to form, it can not only cost a fortune in removal and replacement costs, it can also severely affect your health.

• Ice Dams - Poor attic ventilation can also cause problems in the wintertime. When hot and humid temperatures inside the home leak into the attic due to weak insulation or faulty heating equipment, it can cause the surface of the attic roof to heat up. This will in turn heat up the shingles of the roof. As accumulated snow on the roof heats up and melts, it flows down the roof to the cooler eaves. Here it refreezes into an ice dam, blocking further water from flowing off of the roof. The water must go somewhere and it does—right through roofing materials and into the homes attic.
