1. Extreme Weather Conditions

Union County experiences harsh weather conditions throughout the year, including heavy rain, strong winds and even snow and ice. These weather extremes can seriously affect asphalt shingles in different ways such as:

• Thermal Expansion and Contraction: Fluctuations in temperature cause asphalt shingles to expand and contract, leading to cracks, warping, and granule loss over time.
• Wind Damage: Strong winds can lift and tear shingles, especially if they were improperly installed or reaching the end of their lifespan.
• Ice Dams: During winter, ice dams can form at the roof’s edge, blocking drainage and leading to water seepage under the shingles.
• Hail Damage: Hailstorms can crack or puncture asphalt shingles, affecting their waterproofing ability.

To mitigate these weather-related damages, the best you can do is choose impact-resistant shingles rated for high winds (Class 4 rating), ensure proper attic insulation and ventilation to prevent ice dams, and schedule regular roof inspections after severe weather events.

2. Poor Installation Practices

Improper installation is one of the leading causes of premature asphalt roof failure. The most common installation mistakes include:

• Inadequate Underlayment: Skipping or using low-quality underlayment can lead to leaks and water damage.
• Incorrect Nailing: Overdriven or underdriven nails can cause shingles to loosen or blow off in strong winds.
• Improper Flashing Installation: Weak or missing flashing around chimneys, vents, and skylights can cause water infiltration.
• Poor Ventilation: Inadequate roof ventilation traps heat and moisture, accelerating shingle deterioration.

To ensure proper installation you should hire licensed and experienced roofing contractors familiar with Union County’s building codes and verify that the contractor follows manufacturer guidelines for installation. It is also highly advisable to request a warranty to cover both materials and workmanship.

3. Moisture and Algae Growth

Union County’s high humidity levels can promote moisture-related problems, including algae and mold growth on asphalt roofs. Dark streaks caused by Gloeocapsa magma (a type of algae) go far beyond being just an aesthetic issue. They can also retain moisture, leading to premature shingle decay.

To prevent algae growth you can install algae-resistant shingles (treated with copper or zinc granules), trim overhanging tree branches to reduce shade and moisture retention, and clean the roof periodically with a gentle moss-removal solution (avoid pressure washing, since it can be harmful for shingles).

4. Granule Loss and Shingle Deterioration

Asphalt shingles are coated with granules that protect them from UV radiation and enhance fire resistance.

However, over time, these granules can wear off due to different factors like:

• Aging: As they get older and reach the end of their lifespan (typically 15–30 years), roofs naturally lose granules.
• Storm Damage: Hail and heavy rain can accelerate granule loss over time.
• Foot Traffic: Walking on the roof during inspections or repairs can dislodge granules.

Excessive granule loss exposes the asphalt layer to UV damage, leading to brittleness and cracks. To address this problem, homeowners should inspect gutters for granule accumulation (a sign of significant loss), replace damaged or aging shingles as soon as possible, and, if possible, avoid unnecessary foot traffic on the roof.

5. Material and Labor Cost Increases

The cost of asphalt roofing materials and labor has increased due to factors like inflation, supply chain disruptions, and high demand. For this reason, homeowners in Union County usually face budget constraints when replacing or repairing their roofs.

To effectively handle this situation the best you can do is get multiple quotes from reputable contractors, consider different shingle grades (architectural shingles last longer than 3-tab shingles), and plan roof replacements for the off-peak seasons (fall or spring) when contractors may offer discounts.
