Scottsdale homes — from McCormick Ranch to DC Ranch, Gainey Ranch to Grayhawk — are known for their distinctive tile roofs. But even the best-looking tile roof can hide failing underlayment beneath it. Monument Roofing provides Scottsdale homeowners with thorough inspections, honest assessments, and expert underlayment replacement — including premium systems with a 50-year manufacturer warranty on the material.
Scottsdale has some of the most beautiful tile roofs in Arizona. Barrel tile, flat profile tile, and custom color blends are common on homes throughout the area. But regardless of how attractive or well-maintained the tile looks from the street, the underlayment beneath it faces the same Arizona conditions: 300+ days of sun, summer temperatures above 110°, dramatic temperature swings, and seasonal monsoon storms.
The underlayment is the waterproof layer — the tile is a protective shield. On Scottsdale homes built 15–25 years ago, the original underlayment is often reaching the end of its functional life. The tile may still have decades left. The underlayment may not.
For Scottsdale homeowners who plan to stay in their homes long-term, our premium underlayment system — which uses Tri-Built self-adhered high-temperature peel-and-stick underlayment and carries a 50-year manufacturer warranty on the material — is often the right choice. It's a higher upfront investment that delivers the longest-lasting protection.

Multiple repair attempts on an aging roof without lasting results
Scottsdale homes vary widely in age, roof complexity, and tile style. Some roofs have a single failing section — a valley or a particularly sun-exposed slope — while the rest of the underlayment is still in acceptable condition. In those cases, a section replacement repair addresses the problem without unnecessary work.
On older Scottsdale homes where the underlayment is failing across multiple sections, full underlayment replacement is usually the better long-term investment. It avoids the cycle of repairing one section this year, another section next year, and a third the year after — often at a higher cumulative cost than doing it all at once.
For Scottsdale homeowners choosing full replacement, our premium system with self-adhered peel-and-stick underlayment and a 50-year manufacturer warranty is a popular option. We also offer our standard 40 lb system. We'll explain both and help you decide.
