Frequently Asked Questions

How does Thompson Roofing inspect for and repair roof deck rot common in Columbia?

Our inspection process is thorough, especially in areas prone to moisture. We look for soft spots, sagging, and signs of water intrusion that indicate rot. For repairs, we remove the affected decking and any compromised materials, ensuring the underlying structure is sound before installing new, treated plywood and a proper underlayment. This approach addresses the root cause to prevent recurrence and protect your home's integrity.

What's the best way to remove and prevent black algae stains on my roof in this area?

For existing stains, we use a low-pressure, professional-grade cleaning solution that safely lifts algae without damaging your shingles. To prevent it from coming back, we can apply a zinc or copper-based strip near the roof's peak. As rain washes over these strips, it deposits trace minerals that inhibit algae growth, providing long-term protection specifically suited to our humid local climate.

Why is addressing roof deck rot quickly so important for homes in Columbia, NC?

Roof deck rot compromises the entire structural support of your roofing system. Left unchecked, it can lead to more extensive water damage inside your home, including mold and weakened framing. Given our local humidity and rainfall, a small leak can accelerate rot quickly. Prompt repair by our team stops the damage, preserves your home's value, and ensures your roof can properly handle our coastal weather.
