Monument Roofing is a residential Arizona roofing company serving Chandler, Gilbert, and Scottsdale. We specialize in tile roof underlayment replacement — lifting and resetting your existing tile with a new high-performance waterproofing system. We also provide tile roof leak diagnosis with section replacement repairs, and thorough residential roof inspections. Your tile roof might look fine from the ground — but if it's 15–25 years old, the underlayment beneath the tile could already be failing. We help Arizona homeowners deal with aging underlayment, recurring leaks, and roof sections that need real rebuild work, not surface patches.
We focus exclusively on Arizona residential tile roofs. Underlayment replacement, section rebuild repairs, and detailed roof inspections are what we do every day.
The waterproof layer beneath your tile is the real roof. When it fails — and in Arizona, it often fails before the tile — we lift and number every tile, replace the underlayment with a high-performance system, and reset your original tiles. Same roof profile, decades of renewed protection. This is our primary service and what we do most.
Learn About Underlayment ReplacementNot every leak means you need a full reroof. When the damage is contained, we remove tile in the affected area, replace failed underlayment and battens in that section, inspect the decking, and rebuild the section correctly. Real corrective repair — not a temporary patch that fails next monsoon season.
Learn About Section RepairsA detailed, photo-documented inspection of your tile roof system. We check tiles, underlayment, flashings, valleys, and penetrations. You get clear findings and honest recommendations — not a sales pitch. Know what your roof actually needs before you spend a dollar.
Learn About Inspections
Here's a fact that surprises many Arizona homeowners: the tile on your roof is not the waterproof layer. Tile is a protective shield. The actual waterproofing is the underlayment beneath it — a membrane that sits between the tile and your roof deck.
In Arizona's climate, that underlayment takes a beating. 300+ days of sun per year, summer temperatures above 110°, and dramatic temperature swings between scorching afternoons and cool desert nights cause the underlayment to dry out, become brittle, tear, and lose its ability to keep water out. Monsoon season then exposes every weak point.
The tile itself can look fine from the ground for decades. Concrete and clay tiles often last 50+ years. But the underlayment beneath them typically lasts 20–25 years in Arizona conditions — sometimes less. When homeowners wait until they see visible tile damage, the underlayment has usually been failing for years.
This is why we focus our company on underlayment replacement. It's the repair most Arizona tile roofs actually need — and it's the one that prevents the kind of water damage that costs tens of thousands to fix inside your home.
Learn About Underlayment ReplacementThis is our primary service. Here's what happens when we replace the underlayment on an Arizona tile roof.
Every tile is lifted, numbered, and staged so it goes back in its exact original position.
Old underlayment, deteriorated battens, and failed fasteners are stripped down to the deck.
The wood deck is inspected. Any damaged or rotted sections are cut out and replaced.
New underlayment, battens, and flashings are installed. Tile is reset. Broken tiles are replaced.
Your original tile, reset on a new waterproofing system rated for Arizona conditions.
Here's how we think about tile roof repairs: not every leak means you need a full reroof. We don't push full replacement when a targeted repair is the right answer. But we also don't believe in quick patch jobs that fail again the next time it rains.
When we diagnose a leak, we don't just caulk a crack and leave. We remove tile in the affected area to see what's happening underneath. If the underlayment in that section is compromised, we cut out the failed material, inspect the decking, install new underlayment and battens, and rebuild the section properly.
These repairs — what we call section replacement repairs — typically range from about $1,500 to $4,500 depending on the size and complexity of the affected area. They're real corrective work, not temporary patches.
During the inspection, if we find that the underlayment is failing across large portions of the roof — not just in one section — we'll be honest about that too. In those cases, full underlayment replacement is usually the smarter long-term decision, and we'll explain why in plain language. No pressure. No upselling. Just the facts from someone who's been on your roof and seen the condition firsthand.
Both systems include a full tile lift, deck inspection, and tile reset. The difference is the underlayment material and the warranty.
A proven system for Arizona homes. Standard system jobs typically range from around $12,000–$18,000 depending on roof size, pitch, and decking condition.
50-Year Manufacturer Warranty on Underlayment Material
The premium option for homeowners who want the longest-lasting protection. Self-adhered underlayment seals around fasteners, reducing leak paths. Material warranty covers the underlayment for 50 years.
Every project starts with an inspection so we can give you an honest recommendation based on your roof's actual condition. Not sure if you need a full underlayment replacement or a section repair?

Monument Roofing is a residential Arizona roofing company focused on tile roof underlayment replacement, leak diagnosis, section replacement repairs, and roof inspections for homeowners in Chandler, Gilbert, Scottsdale, and nearby Valley communities. Rather than broad commercial roofing or high-pressure sales, the company provides practical recommendations, clear scopes of work, and specialized Arizona tile roof expertise on every project.
We focus on residential tile roofing, especially underlayment replacement, corrective repairs, and inspection work on Arizona homes.
Many Arizona tile roofs fail beneath the tile before the tile itself wears out. We help homeowners address the real waterproofing issue underneath — replacing aged, brittle underlayment while preserving the tile above.
When a roof leak is localized, we can rebuild the affected section properly — removing tile, replacing failed underlayment, and resetting the area correctly rather than relying on a surface patch that may fail again next monsoon.
Inspections are used to identify whether a roof needs a localized repair or whether broader underlayment failure points toward full replacement. Every inspection includes photos and a clear assessment of the roof's actual condition.
Homeowners should understand what is being replaced, what condition the roof is in, and whether repair or full underlayment replacement makes more sense. We walk through the findings and the plan before any work starts.
