Without proper attic ventilation, your roof and the rest of your home may experience problems that may compromise their structural integrity and affect the health and well-being of your household. These issues can include the following:

5 Issues You May Experience With Poor Attic Ventilation

1. Shortened Roof Lifespan

Your shingles may be at risk of aging prematurely if your inadequately ventilated attic accumulates more heat radiating from the sun overhead. Also, moisture causes your roof deck to rot. Eventually, your shingles will crack or buckle and shed too many granules. Soon after, you’ll be left with a roofing system that’s no longer capable of protecting your home against the weather.

2. Mold and Mildew

An unventilated attic creates a damp environment for mold and mildew to grow. As long as condensation occurs, these organisms can spread quickly and appear on a variety of surfaces, including the roof decking and the attic flooring. If not addressed immediately, they’ll also spread indoors, which can impact the health of everyone in your household.

3. Ice Dams

Warm air trapped inside the attic melts the snow high above the roof. As it runs down toward the roof edge, it refreezes. The cycle repeats until ridges of ice form along the edge of your roof, preventing melted snow from getting drained away from your property. Roof repair contractors recommend addressing attic issues before winter to minimize the formation of ice dams.

4. Rust

Moisture inside a poorly ventilated attic can cause rust and corrosion, especially around the roof’s metal components like nails and fasteners. Eventually, this problem can cause venting and plumbing straps to fail.

5. Sagging Deck

Sagging happens when excess moisture seeps into your roof decking. This moisture dissolves adhesives which hold your decking and shingles together. Eventually, you will notice that your shingles and decking are warping and sagging. Call your local roofing contractor as soon as possible to fix the problem.
