What Is a Glendale Tile R&R? A Homeowner’s Guide to Tile Removal and Replacement

Tile R&R stands for “tile removal and replacement.” This is a roofing process in which a specialized contractor removes the tiles from a roof. Next, they replace the worn-out waterproofing membrane underneath. From there, they reinstall the same tiles, but over a protected surface.

This process has become increasingly popular in Glendale, Arizona. The reason is that local extreme weather conditions affect the lifespan of the materials beneath the tiles. When homeowners find out “what is a tile R&R”, they realize it can be a useful solution for their properties. 

Other homeowners don’t realize that even if the tiles look fine from the outside, the roof may have issues. The waterproofing is located beneath the tiles. That layer can deteriorate before the visible tiles show any damage. For this reason, a Glendale tile R&R may be the best option in these cases.

Why Tile Roofs in Glendale Need an R&R, Not a Full Replacement

At this point, you may be wondering, “Do I need to replace my tile roof or just the underlayment?” Find out here:

The Tile Is Decorative — The Underlayment Does the Waterproofing

Roof shingles are not the primary barrier against water. While they can help—shingles channel water away and protect the roof from the sun—the true waterproofing system is the membrane installed beneath them.

As the years go by, that protective layer beneath shingle roofing systems begins to deteriorate. Especially in Glendale or other cities in Arizona, with constant exposure to heat, the tiles may look solid. However, the underlying material may be nearing the end of its useful life.

How Long Tile Underlayment Lasts in Arizona’s Climate

Glendale’s climate can be harsh on any roofing system. In Arizona, high temperatures can persist for much of the year. This causes the materials to constantly expand and contract. 

This explains why older underlayment systems have a lifespan of 15 to 25 years. Now, there are more modern and durable synthetic options that can withstand high temperatures perfectly for longer periods.

In fact, some homeowners realize their roof is leaking even when the shingles appear to be in perfect condition. What you see on the outside isn’t necessarily what’s happening on the inside.

Signs Your Glendale Tile Roof Underlayment Is Failing

Look out for these signs that may indicate the system under the roof is failing:

If you spot these signs early and hire a roofing contractor, you can prevent more costly damage.

What Does a Tile R&R Actually Involve? Step-by-Step

How does a tile R&R work? Here’s a step-by-step guide:

Step 1 — Tile Removal and On-Site Staging

The tile removal and replacement process begins by removing the existing tiles, taking the utmost care to minimize damage. This makes our subsequent reinstallation process much easier.

The work is done with great care, but a certain amount of breakage is to be expected. It is advisable to have compatible tiles or similar replacement materials on hand, just in case they are needed.

Step 2 — Decking and Substrate Inspection

The shingles have been removed. Now, you should always inspect the roof’s structural framework. Are there any areas damaged by moisture? Is the wood weakened? Are there any sections that are unstable?

If damage is found, it must always be repaired. This is where roof repair services come in handy, so that the new underlayment can be installed afterward.

Step 3 — New Underlayment Installation

This is the most important part of the project. The new waterproofing system must be installed using modern materials—specifically, those that can withstand Glendale’s extreme heat and provide top-notch waterproofing.

We’ll analyze the roof slope and local code requirements. Based on that, we may use self-adhesive membranes, multi-layer synthetic systems, or even high-performance traditional materials—all to ensure you get the best results.

Step 4 — Flashings, Drip Edge, and Bird Stop

Current building codes in Arizona, including Glendale, require additional components. Many older roofs do not have them. Specifically:

• Metal drip edge. This is a metal piece installed along the edges of the roof. Water is directed into the gutters, preventing moisture damage to the wood.
• Ridge cap systems. These are components located at the highest point of the roof that close off open spaces.
• Bird stop to prevent birds from entering. This is a barrier installed near the edge of the shingles. It prevents insects, birds, or debris from entering under the roofing system. 
• New flashings around penetrations and walls. These are metal flashings installed in chimneys, ventilation ducts, or wall joints. The goal is simple: to prevent leaks.

These elements improve the overall durability of the roof. 

Step 5 — Battens and Tile Reinstallation

Finally, wooden battens and original shingles must be installed. The shingles are laid over the waterproofing membrane. However, if any shingles cannot be reused, they are replaced to ensure a satisfactory result.

Tile R&R vs. Full Tile Roof Replacement: Which Makes Sense?

Here we explain the differences between tile roof repair and replacement in Glendale, so you can compare the two options:

Cost Comparison

A Tile R&R offers significant cost savings compared to a re-roofing. The price depends on the following factors:

• Roof size. 
• Extent of structural damage. 
• Type of membrane. 
• Number of broken shingles.

Always try to get everything in writing to avoid hidden costs.

When a Full Tile Replacement Makes More Sense

A Tile R&R is a great solution in many cases. However, there are situations where a complete replacement is preferable. For example:

In that case, it’s a good idea to opt for a new roof installation, as it can provide better results in the long run.

Warranty Differences

With a Tile R&R, the new warranties cover the waterproofing membrane as well as labor. However, they do not always cover reused tiles. Typically, only new components are covered.

For best results, it’s essential to know what the coverage includes before starting the project.

Current Arizona and Glendale Building Code Requirements for Tile Roofs

Here are all the details on Arizona’s tile roof code requirements:

City of Glendale Permit and Inspection Requirements

In Glendale, many commercial and residential roofing projects require municipal permits and inspections. These inspections ensure that the work complies with all applicable standards of the Glendale (Arizona) roofing code. If you don’t have the necessary permits, you may encounter problems in the future when selling the property or filing insurance claims.

ROC Licensing — Why It Matters

Any company that performs this type of work must hold a valid license issued by the Arizona Registrar of Contractors—as we do at Allstate Roofing, with over 25 years of experience. By hiring a licensed professional, you ensure that everything complies with the legal and technical requirements established by the state.

Code Items Required on Every Tile R&R Today

Generally, most projects should include:

• New flashings
• Code-approved underlayment
• Metal drip edge
• Bird stop
• Proper ventilation systems

These elements are essential components of any modern roofing installation.

How to Choose a Glendale Roofing Contractor for a Tile R&R

If you’re planning to make this purchase, you should know how to hire a tile roofer in Glendale:

Verify License, Bond, and Insurance

Before choosing any company, you need to verify that they have:

• A valid license. This confirms that the company is legally authorized to operate.
• Liability insurance. This means that potential property damage during the project is covered.
• Workers’ compensation coverage. This means there is protection against workplace accidents occurring on the property.
• Bond status. There must be financial backing that offers greater protection to the property owner in the event of non-performance.

This reduces legal and financial risks for the property owner. In addition, an A+ rating from the Better Business Bureau (BBB) can be a guarantee of high-quality work. For example, we have one.

Ask for Tile-Specific Experience

Not all roofers have experience with tile systems. To choose the best tile roofing company in Glendale, AZ, you need to make sure they know how to handle tile replacement and removal. Whenever possible, ask to see examples of recent projects and their results.

Get the Underlayment Spec in Writing

A reputable roofing company should clearly specify the underlayment in the contract. For greater clarity, you should request the following:

• Brand of the material
• Type of membrane
• Warranty
• Installation method

This is key to ensuring that everything is done properly.

Confirm Tile Breakage and Salvage Policy

Finally, we recommend asking how the company will handle any tiles damaged during the process. Also, confirm whether the replacement of compatible tiles is included in the estimate, so you have a transparent final price.
