Oakland has some of the oldest homes in the Bay Area: craftsman bungalows, 1920s–40s houses in the hills and flatlands, and plenty of duplexes and small apartment buildings with flat roofs. Many still have several layers of old roofing, steep pitches and complicated flashing around chimneys and dormers. Titanium Roof Innovations handles shingle replacements and flat roof work in Oakland, and every job starts with a free estimate and photos of what we find.
