Rancho Santa Fe Tile Roof Installation | Westlake Saxony 900 Blend Charcoal

July 2026

Custom homes are built one trade at a time, and success depends on every contractor working together. This new construction project near the golf course in Rancho Santa Fe was completed for a general contractor who first noticed our workmanship on another custom home and asked Zenith Roofing Services to install the roofing system on this project. The roof was completed using Westlake Saxony 900 concrete roof tile in Blend Charcoal, installed over Malarkey Right Start UDL synthetic underlayment to create a durable waterproofing system beneath the tile. Throughout construction, our crew coordinated closely with the painters, stucco contractors, window installers, plumbers, deck builders, and other trades to help keep the project moving while ensuring every roofing detail was completed at the proper stage. One of the most interesting photos from this project reveals something homeowners almost never get to see. After removing the original tile roof, the old underlayment showed clear wear patterns where the flat portion of each concrete tile had rested for nearly 30 years. The constant pressure of the tile, combined with decades of Southern California heat, gradually wore through the waterproofing layer beneath the roof. Many people believe concrete tile roofs leak because the tiles wear out. In reality, concrete roof tiles often last many decades. It's the waterproof underlayment beneath the tile that eventually reaches the end of its service life. Since the underlayment is completely hidden once the roof is installed, this deterioration often goes unnoticed until water finally finds its way inside the home. Photos like these are an excellent reminder of why tile roof inspections are so important. A roof can still look beautiful from the street while the waterproofing underneath is quietly reaching the end of its lifespan. Understanding what's happening beneath the tile allows homeowners to plan maintenance before minor deterioration becomes interior damage. This project not only delivered a beautiful new roofing system for a custom home, but also captured a rare look at the hidden aging process that every concrete tile roof eventually experiences.
