The Most Common Roofing Mistakes We See in Rochester Homes

1. Poor Ventilation

Improper attic ventilation is one of the most frequent mistakes we encounter. Without adequate airflow, heat and moisture build up in your attic, leading to mold growth, rotting wood, and ice dam formation in the winter. Over time, this shortens the lifespan of your roofing materials. Proper ridge and soffit vents help keep your attic cool and dry year-round.

2. Incorrect Shingle Installation

It’s more common than you might think: shingles installed with too few nails, nailed in the wrong place, or layered incorrectly. These mistakes can cause shingles to lift, curl, or blow off during Rochester’s high winds. Inadequate sealing is another issue that leaves roofs vulnerable to leaks. Always hire certified roofers who follow manufacturer installation guidelines.

3. Skipping Ice & Water Shield

In a climate like ours, the ice and water shield isn’t optional—it’s essential. This waterproof barrier protects your roof’s most vulnerable areas: eaves, valleys, and around penetrations like chimneys or skylights. We often see leaks and water damage where this protective layer was skipped or improperly installed.

4. Layering New Shingles Over Old Ones

While it may seem like a shortcut to save time and money, adding a second layer of shingles can trap moisture, hide damage, and add unnecessary weight to your roof structure. In Rochester, where snow loads can already be heavy, this can be risky. A full tear-off ensures your new roof starts on a solid, dry, and inspected base.

5. Ignoring Routine Maintenance

Even a well-installed roof won’t last long without regular care. Clogged gutters, missing shingles, and flashing damage can lead to leaks if left unaddressed. We recommend having your roof inspected annually—especially after storms or harsh winters—to catch minor issues before they become major ones.

Your roof is your home’s first line of defense against Rochester’s challenging weather. Don’t leave it to chance. By avoiding these common roofing mistakes—and working with a reputable, experienced local contractor—you can ensure your roof stands strong for years to come.
