Gilbert has grown rapidly, and many of the homes built here over the last 15–25 years have tile roofs. Those roofs are now reaching the age where the underlayment — the waterproof layer beneath the tile — may be due for replacement. Monument Roofing helps Gilbert homeowners understand what's happening on their roof and provides honest, expert underlayment replacement, section repairs, and inspections.
Gilbert's housing stock has a high concentration of tile roofs on homes built from the mid-1990s through the early 2010s. Those roofs are now 15–30 years old — right in the window where original underlayment reaches the end of its service life in Arizona's climate.
Arizona's heat, UV exposure, and temperature swings cause underlayment to dry out, become brittle, and tear over time. Monsoon storms then find every weak point. The tile itself can look fine from the ground — concrete and clay tiles often last 50+ years — while the waterproof layer beneath it is failing.
If your Gilbert home is approaching or past the 20-year mark with its original underlayment, the question isn't usually whether the underlayment will need replacement — it's whether you want to address it before interior water damage makes the decision for you.

Roof age of 15–25 years with original underlayment
Leaks appearing during or right after monsoon storms
Multiple previous repairs or recurring leaks in different spots
Not every Gilbert home with a leak needs full underlayment replacement. When the failure is limited to one section — a valley, a south-facing slope, or an area around a penetration — a section replacement repair may be the right approach. We remove tile in the affected area, cut out the failed underlayment and battens, inspect the decking, and rebuild the section correctly.
When inspection shows underlayment failure across multiple sections — which is common on Gilbert homes approaching the 20-year mark — full underlayment replacement is usually the smarter long-term investment. It addresses the whole roof system at once rather than chasing leaks section by section over several years.
Every Gilbert project starts with an inspection. We'll show you photos, explain what we find in plain language, and give you an honest recommendation.
