RR Alvarez Roofing | Roofing Services in San Francisco, CA 94112

In San Francisco, heavy rain can overwhelm old or clogged gutters, causing water to back up under your roof shingles and lead to leaks. Our professional gutter installation ensures proper sizing, pitch, and downspout placement to efficiently channel water away from your roof and foundation. This direct management of rainwater is a key defense against the leaks many local homes experience after storms.

San Francisco's moist climate encourages moss, algae, and debris accumulation on roofs. This buildup can trap moisture against the roof deck and, critically, around the metal flashing—the seals around chimneys, vents, and valleys. Over time, this moisture can cause the flashing to corrode or lift. Our thorough roof cleaning removes these elements, helping to preserve the integrity of your flashing and prevent one of the most common sources of leaks.

A roof in San Francisco needs to handle wind, fog-driven moisture, and intense rain. For a durable installation, we focus on high-quality, weather-resistant materials, reinforced roof decking, and most importantly, expert flashing details. Properly installed flashing around all penetrations and in valleys is the frontline defense against leaks. Our new roofs are built with these local stressors in mind to provide long-term protection for your home.
