Comprehensive waterproofing solutions for roofs, decks, and structures — because water always finds a way in if you let it.
Proper waterproofing is your first and most important line of defense. Waterproofing is about more than just keeping rain out. It's a comprehensive approach to protecting your roof, deck surfaces, parapets, and structural elements from the cumulative effects of moisture intrusion — effects that can silently compromise a building's structure, air quality, and value over time. At Advanced Roofing and Sons, Inc., we provide professional waterproofing solutions for both residential and commercial properties across Southern California, tailored to the specific surface, exposure, and performance requirements of each project.
Southern California's climate is often misunderstood when it comes to moisture risk. While rainfall is infrequent, when it does come it can be intense — and flat roofs, rooftop decks, balconies, parapets, and below-grade structures have limited margin for error. A single compromised seam, failed flashing, or unprotected penetration can allow water to travel far from its entry point before damage becomes visible. Our waterproofing services address every vulnerable surface systematically, ensuring no weak points are left exposed.
• Flat and low-slope roof membranes
• Rooftop decks and walkable deck surfaces
• Balconies and elevated concrete surfaces
• Parapets, walls, and coping
• Planter boxes and green roof assemblies
• Flashings, penetrations, and transitions
• Below-grade and foundation-adjacent structures
At Advanced Roofing and Sons, Inc., we approach every waterproofing project with the same philosophy — find every potential point of failure and eliminate it. With over 31 years of experience waterproofing structures across Southern California, we know where water hides, how it travels, and exactly how to stop it.
