Those dark streaks are typically a type of algae called Gloeocapsa magma, which thrives in Durham's humid climate. It feeds on the limestone filler in asphalt shingles. While not immediately damaging to the roof's structure, it can retain moisture and accelerate granule loss over time. A professional cleaning or treatment can remove the stains and help preserve your roof's lifespan.

Nail pops are common in our area due to temperature fluctuations and the natural settling of your home's framing. As the wood expands and contracts, it can push the roofing nails upward, breaking the sealant and potentially creating a leak point. It's important to have these addressed promptly by a roofer who can properly resecure and seal the area to prevent water intrusion.

We recommend checking your roof, gutters, and attic twice a year—spring and fall. Look for missing or cracked shingles, accumulated debris in valleys and gutters, signs of moss or algae growth, and any visible nail pops. Also, check your attic for daylight coming through the roof boards or signs of moisture stains. Spotting these issues early can prevent costly repairs from water damage.
