San Francisco's coastal winds and moisture make roof flashing—the metal strips sealing joints and edges—especially vulnerable. Failure is a common local issue that leads directly to leaks and water damage inside walls and attics. Our inspections meticulously check flashing around chimneys, vents, and valleys. If we find failure, our repair or replacement uses high-grade, corrosion-resistant materials and precise installation techniques to withstand the local elements, ensuring a lasting seal for your home.

Our comprehensive moisture control inspection identifies sources of unwanted dampness, from inadequate attic ventilation to compromised vapor barriers. For San Francisco homes, this is key to preventing mold and structural rot. If installation is needed, we properly install or repair moisture and vapor barriers, often in crawl spaces, basements, and attics. We focus on creating a continuous protective layer and improving airflow, using quality materials suited to our local climate to safeguard your home's health and integrity.

Our family-owned approach means you get direct, accountable service. For gutter addition, cleaning, installation, or replacement, we assess your home's specific needs, like its roof pitch and drainage patterns. We don't just install gutters; we ensure the entire system—including downspouts—effectively directs water away from your foundation, which is vital in San Francisco to prevent foundational erosion and basement moisture issues. Our work is precise, clean, and built to handle the seasonal rains.
