The black streaks on Durham roofs are a resilient algae called Gloeocapsa magma, which thrives in our humid climate. While DIY cleaning is possible, improper methods can damage shingles. We recommend a professional, low-pressure soft wash with an EPA-approved, zinc-based solution. This safely removes existing stains, and we can also install zinc or copper strips along the roof ridge. As rain runs over these strips, it deposits trace minerals that inhibit future algae growth for years.

Chimney flashing leaks are very common here due to the constant expansion and contraction of materials from our temperature swings, which can break the seal. A permanent fix requires more than just caulk. We remove the old flashing, inspect the chimney structure and roof deck for hidden water damage, then install new, custom-fitted step flashing and counter-flashing. We use durable metals like aluminum or copper and seal all joints with a high-grade waterproof membrane to create a watertight system designed for North Carolina's weather.

Our Durham-specific roof inspection focuses on local trouble spots. We check for algae damage on north-facing slopes, examine all flashing points (chimneys, vents, valleys) for seal failure, look for granule loss from sun exposure, and assess for storm damage from high winds. We also inspect attic ventilation, as poor airflow in our climate can lead to moisture buildup and premature aging. You'll receive a detailed report with photos and clear explanations, so you understand exactly what we found and what needs attention.
